iiiII Important Safety Information The list of dangers, warnings and cautions in this section contain important information that will help ensure safe operation of the system. Please read carefully and understand all of these items. All installers, operators and maintenance personnel should read and understand this information before installation, use, or maintenance of the FDL01TU system. The FDL01TU system by itself is not inherently dangerous. HOWEVER, WHEN THE FDL01TU IS CONNECTED TO OTHER EQUIPMENT FOR THE PURPOSE OF CONTROL, SAFETY AND ALL POSSIBLE ASSOCIATED DANGERS MUST ALWAYS BE GIVEN THE UTMOST CONSIDERATION DURING SYSTEM INTEGRATION, DESIGN, INSTALLATION, AND USE. The FDL01TU system may be used in virtually unlimited applications. Many of these associated systems can, by themselves, pose a mechanical, electrical or other hazard to operators and other persons or equipment. To address all possible applications and associated safety hazards in this manual would be impossible. The warnings below and throughout this manual give information that will allow safe installation and use the modem system applications. If you have questions regarding the safety of your specific application, please contact the appropriate people for help. Your Futaba sales representative, representatives of the equipment being controlled, and the technical support staff at local branch of Futaba Corporation are among those who can provide assistance with your safety concerns. The following warnings are included in the lists that follow but warrant repetition here: In installations where the FDL01TU system is used to control motion or operation of potentially dangerous equipment, it is imperative for safety that all operators and installers be thoroughly trained in the normal function of that equipment before attempting to control it remotely with the FDL01TU system. To help ensure safe operation of the equipment, the FDL01TU system must be connected so that it will operate in a fail-safe way. In other words, the equipment being controlled should stop or return to its safest state in the absence of a control signal or total loss of RF transmission from the FDL01TU system. Our system uses one of the most reliable methods available to transmit data using radio signals. Many factors can affect a radio signal that may block it or interfere enough to disrupt regular transmission. Because of this, equipment motion or dangerous electrical current, for example, that continues during a loss-of-signal condition could be very dangerous.

iv Four symbols are used in the margin of the following section and throughout the manual to indicate the level of hazard or information listed. The symbols are defined as follows: Indicates a hazard that will cause severe personal injury, death, or substantial property damage if the warning is ignored. Indicates a hazard that can cause severe personal injury, death, or substantial property damage if the warning is ignored. Indicates a hazard that will or can cause minor personal injury, or property damage if the warning is ignored. Indicates installation, operation, or maintenance information that is important but not hazard-related. Please read the following safety information carefully. Some of these notices are duplicated throughout the manual, in areas of associated content, for your benefit. II.I General Safety Hazards and Notes Improper installation and/or operation of the FDL01TU system can cause serious or fatal injuries to the operator or nearby persons and cause damage to the FDL01TU system, and any equipment it is used to control. Please read and understand this manual completely and the manual of all equipment being controlled before attempting to operate or install this system. Always keep this manual at a location readily accessible to anyone operating the system and related equipment. Ensure that all operators have read and understood this manual, especially all safety and operation procedures contained in it. Please refer to the section in this manual titled How to Obtain Help for the contact that can supply additional manuals or answers to questions not covered in this manual. If this product is passed on to a different user, be sure that this manual accompanies the product. Be certain that the installer of this equipment reads and understands the instruction manual of the equipment that is being connecting to before attempting this installation. The FDL01TU modem should NOT be used in a manner in which failure of the product or loss of the radio signal could cause damage

v to the equipment being controlled, or to anything in the area in which such equipment is located. All integrated control systems should be designed for “fail-safe” operation so that a temporary or permanent loss of signal will not endanger any person, critical process, or equipment (refer to the beginning of the safety section for further explanation). The system design should ensure that the equipment being controlled will default to its safest state in the event of signal loss. The FDL01TU modem contains no user serviceable parts. If the unit requires service, contact your sales representative or local branch of Futaba Corporation per instructions the section titled How To Obtain Help. Do not disassemble or attempt to repair the FDL01TU yourself. Doing so could void your warranty and may void the user’s authority to operate the device. Contact Futaba before using the FDL01TU modem in safety critical applications such as medical equipment, aircraft, hazardous materials handling, etc. II.II Installation Safety Hazards and Notes When mounting the FDL01TU modem, use M2 (ISO) screws that project 2 to 3 mm into the modem. Screws that project further into the modem (3.5mm MAX) may permanently damage the internal components and/or cause the FDL01TU modem to malfunction. Use only the proper regulated DC voltage supplied to the FDL01TU modem. Use of any other voltage may permanently damage the modem and/or cause the modem to malfunction and create a shock or fire hazard. Be certain that all AC power outlets used the power adapters have been properly installed, grounded, and fused. An electrical shock hazard may exist if this unit is powered by a faulty power outlet or source. If such a situation is discovered, immediately discontinue use until the power source and outlet have been properly installed, grounded, and fused by an electrician or other authorized person. Be sure to wire the power and serial connections correctly. Incorrect wiring can damage the system, cause it to malfunction and/or create a shock and fire hazard. Ensure that the FDL01TU modem power and the power to the equipment to be controlled is turned off before connecting or disconnecting the cable between them. This will help prevent

vi accidental damage to the system and unexpected operation and/or injury. Be sure the FDL01TU modem power, the power to the equipment that is being connecting to it, and the DC power source are all turned off before wiring and connecting the power cable. Be sure that the supplied power is within the specified range (3.5 to 7.0 VDC). Voltages outside the specified range may damage the FDL01TU modem. Be sure that the power source has sufficient current capacity. Insufficient current may cause the unit to malfunction. Securely attach the antenna cable, and serial communication connector to the FDL01TU modem and equipment/power source to which it is connected. Failure to do so could cause an unexpected system failure. II.III Antenna Installation Hazards and Notes Be sure to keep all systems and antennas clear of power lines. Permanent equipment damage and severe shock injury or death can occur if the system contacts power lines. This device has been designed to operate with an antenna having a maximum gain of 2.14 dB. Antenna having a higher gain is strictly prohibited for use with this device. The required antenna impedance is 50 ohms. Contact Futaba before connecting any antenna not provided by Futaba specifically for the FDL01TU modem. Attaching any non-authorized antenna may be in violation of FCC regulations. To reduce potential radio interference to other users, the antenna type and its gain should be so chosen that the equivalent isotropically radiated power (e.i.r.p.) is not more than that permitted for successful communication. When using two antennas with a single FDL01TU modem for diversity reception, mount the antennas as far apart as possible (6 cm minimum). If the antennas are too close, the diversity advantage will not be achieved.

vii Before each use, verify that the antenna (and antenna cable, if used) is securely attached and in good condition. A loose antenna or cable may severely reduce the operating range of the system. When installing the FDL01TU modem in a mobile unit such as an Automated Guided Vehicle (AGV), Futaba recommends to use the diversity reception feature as a remedy for multipath fading problems. For diversity reception, install the two antennas as far apart as possible in order to gain maximum benefit (6 cm minimum). The FDL01TU operates at frequencies in the 2.4 GHz band. These frequencies are more directional than lower frequencies and are easily reflected. If there are metal structures nearby, the effective range may be shortened or the directional properties may be further narrowed. To help avoid this, mount the antenna as far away as possible from surrounding metallic structures. Multipath problems occur easily at frequencies in the 2.4 GHz band. When multipath problems are present, moving the antenna as little as 10 cm may result in improved communication or, conversely, worsened or complete loss of communication. Futaba recommends that the mounting position of the antenna be determined after testing and verifying optimal communication conditions. Negative multipath effects can also be overcome with antenna diversity. See p.8 DIVERSITY ANTENNA SETUP and the related register settings for more details regarding antenna diversity function. When installing multiple FDL01TU modem systems that will use different frequency groups in the same area, modem’s antennas of different frequency groups must be mounted at least 6 feet (2 meters) apart. Failure to do so may severely reduce the modem operating range. Please contact Futaba for information about antenna separation when using the FDL01TU and other wireless products in the same area.

viii II.IV Environmental Safety Hazards and Notes If the FDL01TU modem has been stored at a temperature beyond the specified operating temperature range for the system, it may not function properly. Allow it to return to normal temperatures before use. Refer to APPENDIX A – TECHNICAL SPECIFICATIONS for the actual operating temperature range. The FDL01TU modem is a precision electronic device with a rugged design that is intended for industrial applications. However, do not install it where it will encounter excessive vibrations. In some cases, isolation mounts may be used to isolate the modem from the equipment’s vibration. Excessive vibration can permanently damage the modem and/or cause it to malfunction. Do not operate the FDL01TU modem in environments where it will be subjected to excessive moisture (such as rain or water spray), dust, oil, or other foreign matter (such as metal particles). Doing so may permanently damage the modem and/or cause it to malfunction. If it does become wet or contaminated, correct the situation, verify proper operation and have any problems corrected before using it to control other equipment. If necessary, the modem can be mounted inside a protective or waterproof enclosure. If the enclosure is metallic, the antenna must be mounted externally or the effective operating range will be severely limited. The FDL01TU is designed for indoor use. When using it outdoors, the modem should be mounted in a waterproof enclosure and the ambient temperature range should be checked to insure that it is within the modem’s specifications. Always use the modem within its specified environmental ranges. II.V Other Notice Italicized gothic word used in this manual shows functional and technical term especially important for the FDL01TU modem.

ix Operational Safety Hazards and Notes Before each use of the FDL01TU modem, ensure that the area where the equipment will be operated is clear of people or obstacles that may affect its safe operation. Before each use of the FDL01TU modem, verify that both the equipment being controlled and the modem are in proper operating condition. When rewriting the FDL01TU modem’s memory registers, do not turn the modem’s power off until the modem returns a “P0” response. If the power is interrupted before a P0 response is returned, the memory contents may be lost or corrupted and the modem operation will be unpredictable. If the memory contents are lost or corrupted, they may be restored to original default settings by reinitializing them. (See p.25 Memory REGISTER INITIALIZATION for more details.) Do not attempt to operate remotely controlled equipment outside the communication range of the FDL01TU system. Doing so could cause loss of control of the equipment. Without implementing proper serial communication flow control settings, the baud rate between the modem and its terminal equipment (wire linked) can exceed the wireless link data rate and cause the modem buffer to overflow. This can result in malfunction of the systems being controlled and/or data corruption. Ensure that the appropriate flow control settings are being used for your upper layer application protocol. Operation is subject to the following two conditions: (1) this device may not cause interference, and (2) this device must accept any interference, including interference that may cause undesired operation of the device.

52SECTION 2 SYSTEM INSTALLATION

62.1 Wireless Modem Installation 2.1.1 Mounting Method 1 A method to mount the modem directly on a surface using the mounting holes at the side of the modem’s print circuit board. When using this method, provide a guide on the opposite side, because two holes are not sufficient to securely mount the modem. Figure 2–1: Mounting Method 1 2.1.2 Mounting Method 2 To mount the modem using the holes on a flat horizontal surface, which are 3.5mm deep for M2 screws. When using this method, use M2 screws which project the hole 2 to 3mm deep. The screw tightening torque is below 2.5kg cm. Mount the modem on a flat plane and be careful that there is no torsion applied. For the position of the mounting holes, see p.68 DIMENSIONS. Figure 2–2: Mounting Method 2 Be careful not to allow water, oil, dust and other foreign particles (especially metal particles) to enter inside, which may damage the unit. Since the FDL01TU modem is a precision electronic device, install it at a place free of excessive shock and vibration to prevent the unit from damage. WARNINGM2 Screw WARNING

7The FDL01TU is designed to be used inside the room. In case of using it outdoor, be sure to use it within the extent limited by the environmental specification, and check the ambient temperature and the state of water-proof. 2.2 Communication Cable Connection Use the serial communication cable prepared by Futaba to connect the FDL01TU modem to the external terminal equipment. For the connection of the modem, see p.22 PIN ASSIGNMENT. The signal level of the FDL01TU is CMOS. If the interface of the equipment to be connected is RS232C or RS485, the level conversion circuit is required. For the example of the level conversion circuit, see p.64 CONVERSION CIRCUIT. Figure 2–3: Connection of Communication Cable Ensure that the FDL01TU modem power and the power to the equipment to be controlled is turned off before connecting or disconnecting the cable between them. This will help prevent accidental damage to the system and unexpected operation and/or injury. In addition to this manual, read the operation manual of a PC (Personal Computer) and PLC (Programmable Logic Controller) to be connected. 2.3 Antenna Connection At least one antenna must be connected to Antenna Connector A on each FDL01TU modem in use. In the environment where multipath fading exists with reliable communication requirements, a second antenna can be installed to Antenna Connector B for the diversity receive function to improve reception performance. 2.3.1 Single Antenna Setup Always use Antenna Connector A when installing a single antenna. Refer to the figures below for details about the actual mounting and connecting methods. CAUTIONWARNINGWARNING

8 Figure 2–5: Connecting the Antenna 2.3.2 Diversity Antenna Setup In certain situations, reception can be improved by using the integrated antenna diversity feature. This is accomplished by using two separate antennas and enabling the diversity function in REG19 (see p.27 MEMORY REGISTER DESCRIPTION). Refer to the figures below for details about the actual mounting and connecting methods. Figure 2–6: Connecting Two Antennas When using two antennas with a single modem for diversity reception, mount the antennas as far apart as possible (at least 6 cm). If the antennas are too close, the diversity advantage will not be achieved. CAUTION

92.4 Other Installation Precautions 2.4.1 Modem Installation Precautions Securely attach the antenna cable, and serial communication connector to the FDL01TU modem and equipment/power source to which it is connected. Failure to not do so could cause an unexpected system failure. The FDL01TU modem is a precision electronic device. Its rugged design is intended for industrial applications. However, do not install it where it will encounter excessive vibrations. In some cases, isolation mounts may be used to isolate the modem from the equipment vibration. Excessive vibration could permanently damage the modem and/or cause it to malfunction. If the FDL01TU modem has been stored at a temperature beyond the specified operating temperature range for the system, it may not function properly. Allow it to return to normal temperatures before use. Refer to p.66 SPECIFICATION for the actual operating temperature range. Do not operate the FDL01TU modem in environments where it will be subjected to excessive moisture (such as rain or water spray), dust, oil or other foreign matter (such as metal particles). Doing so may permanently damage the modem and/or cause it to malfunction. If it does become wet or contaminated, correct the situation, verify proper operation and have any problems corrected before using it to control other equipment. If necessary, the modem can be mounted inside a protective or waterproof enclosure. If the enclosure is metallic, the antenna must be mounted externally or the effective operating range will be severely limited. The FDL01TU is designed for indoor use. When using it outdoors, the modem should be mounted in a waterproof enclosure and the ambient temperature range should be checked to insure that it is within the modem’s specifications. Always use the modem within its specified environmental ranges. 2.4.2 Antenna Installation Precautions Before each use, verify that the antenna (and antenna cable, if used) is securely attached and in good condition. A loose antenna or cable may severely reduce the operating range of the system. WARNINGWARNINGWARNINGWARNINGWARNINGWARNING

10Avoid mounting the antenna near large metallic objects or inside metal enclosures. Such objects can severely reduce the operating range of the system. When installing the FDL01TU modem in a mobile unit such as an Automated Guided Vehicle (AGV), Futaba recommends using the diversity receive function as a remedy for to multipath fading problems. For diversity reception, install the two antennas as far apart as possible in order to gain maximum benefit (Actual recommendation is 30 cm, 6 cm at least). The FDL01TU operates at frequencies in the 2.4 GHz band. These frequencies are much directional than lower frequencies and are easily reflected. If there are metal structures nearby, the effective range may be shortened or the directional properties may be further narrowed. To help avoid this, mount the antenna as far away as possible from surrounding metallic structures. Multipath problems occur easily at 2.4 GHz frequencies. When multipath problems are present, moving the antenna as little as 10 cm may result in improved communication or, conversely, a further diminished or total loss of communication. Futaba recommends that the mounting position of the antenna be determined after testing and verifying optimal communication conditions. Negative multipath effects can also be overcome with antenna diversity. See p.8 DIVERSITY ANTENNA SETUP and the related register settings for more details regarding antenna diversity. 2.4.3 Multiple FDL Modems Installation Precautions When installing multiple FDL (series) modem systems that will use different frequency groups in the same area, modem’s antennas of different frequency groups must be mounted at least 6 feet (2 meters) apart. Failure to do so may severely reduce the modem operating range. Please contact Futaba for information about antenna separation when using the FDL01TU and other wireless products in the same area.

113SECTION 3 SYSTEM OPERATION

123.1 Data Transparent Mode 3.1.1 What Is Data Transparent Mode? In data transparent mode, the FDL01TU modems are continuously connected in a 1:1 configuration. Full-duplex communication is simulated between the two terminals using a method in which each modem rapidly switches between transmitting and receiving (referred to as Time-Division-Duplex (TDD) transmission). With the exception of FDL01TU modem commands, all data input from the sending terminal are transmitted to the receiving terminal. Using this mode, the user can simply replace a serial cable with a pair of FDL01TU modems and communicate without any special software or hardware requirements. 3.1.2 Time-Division-Duplex Transmission and ARQ Function As noted above, when in data transparent mode, data packets are exchanged between terminals the modems rapidly switching between transmitting and receiving, simulating full-duplex communication. Data input to the sending FDL01TU modem are assembled together with error detection bits and other control data, and then transmitted to the receiving modem. If an error is detected by the receiving modem, it will continue to request retransmission of the packet from the transmitting modem until it receives a valid packet. This is referred to as the Automatic Retransmission Request (ARQ) function. The ARQ function greatly enhances the reliability of the wireless connection because it ensures that the receiving FDL01TU modem will not pass corrupted data on to its terminal. Figure 3–1: Send/Receive Timing Diagram 3.1.3 Connection Method Link is connected and disconnected with the CON and DCN commands. Receiving modems can be shifted among many others by designating station addresses. Wireless Modem A send receive send receive sendWireless Modem B receive send receive send receivepacket length A packet length Btime (t)

133.2 Packet Transmission Mode Packet transmission mode operates as half-duplex communication and requires explicit commands to control the modem transmissions. Because this mode allows the addressing of different destination receiver modems by embedding the address in the data packets, it is best suited for 1:n and n:m topology applications. In packet transmission mode, the FDL01TU modem normally waits in a ready-to-receive state. When a transmission command is issued to the sender modem from its terminal equipment, the modem searches for a clear frequency channel and, when found, transmits the message to the intended destination receiver modem. Packet transmission mode also allows expansion of the effective wireless communication range by using an additional FDL01TU modem configured as a repeater. 3.2.1 Packet Transmission Mode Protocol In packet transmission mode, after a data packet is transmitted from the sender modem (station) to a destination station, the destination station acknowledges successful communication by returning an acknowledgement (ACK) packet to the sender modem. The sender modem waits for the ACK packet and when it is received, indicates that the transmission was successful. If it does not receive an ACK packet, it will continue to retransmit the data packet until it does receive an ACK packet or until the retransmission count (REG11 or RNO command setting) reaches the preset limit. If the sender modem receives an ACK packet anytime during the retransmission attempts, it returns a “successive completion response” (P0) code to its terminal equipment. If the modem does not receive an ACK packet, it returns a “transmission failed” (N1) code to its terminal equipment. Sender Modem Destination Modem Figure 3–2: Packet Transmission and ACK response 3.2.2 Broadcast Transmission Protocol Broadcast transmission (sending the same data to multiple modems simultaneously) is possible in packet transmission mode by setting 255 as the destination address (REG02). However, because ACK packet are not returned when executing the broadcast transmission, the sender modem does not receive confirmation of the “successful reception” of the transmitted data from any of the receiver modems. In broadcast transmission, the sender modem transmit the data packet the number of times equal to the preset retransmission count (REG11 or RNO command setting) plus Data Transmission ACK response

14one and then it outputs a successive completion response (P0) to its terminal equipment. When the remote receiver modems receive the transmitted data successfully, they output the data to their terminal equipments normally and do not return ACK packet. Once a valid data packet has been received correctly by a receiver modem, rest of data received during any subsequent retransmissions are discarded and not output to its terminal equipment. Sender Modem Remote Modem Figure 3–3: Broadcast Transmission 3.2.3 Transmit Command and Receive Header Six transmit commands can be used in packet transmission mode . Both text and binary data can be sent directly from modem-to-modem or sent through a third FDL01TU modem configured as a repeater. The receiver modem automatically determines the transmitted data format and communication path from the information in the received packet header. Refer to the table below for a list of the transmit commands and the corresponding header component. Transmit Command Receive Header Function TXT RXT Text data transmission TBN RBN Binary data transmission TXR RXR Text data transmission via repeater TBR RBR Binary data transmission via repeater TX2 RX2 Text data via two repeaters TB2 RB2 Binary data via two repeaters Table 3–5: Transmit Commands and Receive Headers Data Transmission Retransmission Retransmission Retransmission ・・・ End

15The following list shows each command’s syntax as issued at the sender terminal equipment and the response displayed at the receiver terminal equipment when the packet is received. 1. Direct Text Data Transmission transmit: @TXT [destination address]{source address}[message] receive: RXT [source address][message] CR/LF 2. Direct Binary Data Transmission transmit: @TBN[destination address]{source address}[message length][message] CR/LF receive: RBN [source address][message length][message] CR/LF 3. Text Data Transmission through Repeater transmit: @TXR [repeater address][destination address]{source address} [message] CR/LF receive: RXR [repeater address][source address][message] CR/LF 4. Binary Data Transmission through Repeater transmit: @TBR [repeater address][destination address]{source address} [message length][message] CR/LF receive: RBR [repeater address][source address][message length][message] CR/LF where {source address} is optional, used in RS485 mode set by serial communication cable 12 pin. The following list defines the parameters and symbols used in the commands above: @ = command header CR/LF = carriage return + line feed destination address = address of modem to receive the message (000 to 239) source address = address of modem sent the message (000 to 239) repeater address = address of the repeater modem (000 to 239) message length = number of bytes in message message = information data (255 bytes or less) In the text data transmission, the message is considered to be terminated when the CR/LF code appears in it. No data after that will be transmitted. When the CR/LF code contains in a message, use the binary data transmission command. CAUTION

163.3 Headerless stream Mode 3.3.1 Operation in the headerless stream mode The headerless stream mode is a specific transmission mode to set transmission data without the packet header, employing the protocol of the packet transmission mode. Parameters such as receiver or repeater addresses are set either by the memory register or by the command. A transmission data packet is automatically terminated by the specific character (terminator). Command responses (P1, P0) are not output. In the headerless stream mode, since the transmission data is no longer to be issued as the transmission command. At the end to end of the wired link, existing upper layer application protocol can be used without awareness of the wireless link protocol. This mode can communicate with the normal packet transmission mode interactively. This mode cannot be used in the RS485 mode. 3.3.1.1 Format of the headerless stream mode In the headerless stream mode, no response (P1, P0) following the transmission command is output. Instead of outputting the receive header or the CR/LF code, the specific characters (terminator) is output which separates data to a transmission packet at the sender end. Since the transmission packet contains the sender’s address, data format (text or binary mode) and the repeater address, the headerless stream mode is compatible with the normal packet transmission mode and the interactive communication can be performed between them. The transmission and receiving formats in the headerless stream mode are as follows. 1. Packet transmission mode (for the reference below) Sender: @TXT002HELLO CR/LF -> Receiver: RXT001HELLO CR/LF 2. Headerless stream mode (when terminator is CR/LF) Sender: @HELLO CR/LF -> Receiver: HELLO CR/LF 3. When the receiver is in the packet transmission mode (text mode) Sender: @HELLO CR/LF -> Receiver: RXT001HELLO CR/LF 4. When the receiver is in the packet transmission mode (binary mode) Sender: @HELLO CR/LF -> Receiver: RBN001HELLO CR/LF CR/LF 5. When sender is in the packet transmission mode Sender: @TXT002HELLO CR/LF -> Receiver: HELLO When the receiver is in the packet transmission mode, be careful about the terminator. For details, refer to REG23 of p.27 MEMORY REGISTER DESCRIPTION.

17The difference between the text mode and the binary mode does not matter in the headerless stream mode. 3.3.1.2 Commands for the headerless packet mode The same command as used in the packet transmission mode can be used, but the following commands which attempted transmission cannot be used. TXT, TXR, TBN, TBR, RPT, RTY. 3.3.1.3 Repeater in the headerless packet mode The repeater also can be used in the headerless stream mode. The repeater address is set with the memory register or the PAS command. The repeater itself no needs to be in the headerless stream mode. Set REG18:bit 5 whether the repeater is used or not. The address of the repeater is set using REG08 and REG09 or PAS command. 3.4 Power Down Mode The FDL01TU has three power down modes. Select the mode according to the power supply operating conditions such as battery powered application. (1) Active Mode This mode is not the power down mode but always capable of transmitting and receiving data. The modem is in the active mode when the power is turned on. The current consumption is 110 mA maximum in this mode. (2) RF Block Power Down Mode This mode shuts down the power supply of the RF circuit block, where only the control (logic) circuit is activating. Since the control circuit is in operation, the setting of memory registers are retained. When the modem returns to the Active mode, it can continue its operation since the register value is retained. Furthermore, functions such as referencing and setting memory registers can be used in this mode. This mode is invoked by the following commands. ROF command: to become the RF block power down mode RON command: to return to the Active mode The current consumption is about 35 mA in this mode.

183.5 Frequency Grouping 3.5.1 Frequency Allocation The FDL01TU can operate on 76 available frequencies between 2403 MHz and 2480 MHz with 1 MHz separation between each frequency. See the table below for the exact frequency assignments. Freq.No. Freq.(MHz) Freq.No. Freq.(MHz) ０２４０３．３２８４５２４４９．４０８１２４０４．３５２４６２４５０．４３２２２４０５．３７６４７２４５１．４５６３２４０６．４００４８２４５２．４８０４２４０７．４２４４９２４５３．５０４５２４０８．４４８５０２４５４．５２８６２４０９．４７２５１２４５５．５５２７２４１０．４９６５２２４５６．５７６８２４１１．５２０５３２４５７．６００９２４１２．５４４５４２４５８．６２４１０２４１３．５６８５５２４５９．６４８１１２４１４．５９２５６２４６０．６７２１２２４１５．６１６５７２４６１．６９６１３２４１６．６４０５８２４６２．７２０１４２４１７．６６４５９２４６３．７４４１５２４１８．６８８６０２４６４．７６８１６２４１９．７１２６１２４６５．７９２１７２４２０．７３６６２２４６６．８１６１８２４２１．７６０６３２４６７．８４０１９２４２２．７８４６４２４６８．８６４２０２４２３．８０８６５２４６９．８８８２１２４２４．８３２６６２４７０．９１２２２２４２５．８５６６７２４７１．９３６２３２４２６．８８０６８２４７２．９６０２４２４２７．９０４６９２４７３．９８４２５２４２８．９２８７０２４７５．００８２６２４２９．９５２７１２４７６．０３２２７２４３０．９７６７２２４７７．０５６２８２４３２．０００７３２４７８．０８０２９２４３３．０２４７４２４７９．１０４３０２４３４．０４８７５２４８０．１２８３１２４３５．０７２３２２４３６．０９６３３２４３７．１２０３４２４３８．１４４３５２４３９．１６８３６２４４０．１９２３７２４４１．２１６３８２４４２．２４０３９２４４３．２６４４０２４４４．２８８４１２４４５．３１２４２２４４６．３３６４３２４４７．３６０４４２４４８．３８４

193.5.2 Frequency Group Operation The FDL01TU can operate on a fixed frequency or on any frequency in a set of frequency group. Multiple FDL01TU systems can be use different frequency groups and operate in the same area without mutual interference between the systems. When the RF environment is relatively clean, wireless channel links can be made on a fixed, clear frequency (no interference) by using Grouping Method A. In less than ideal RF environments, it is better to use multiple frequencies method in the frequency group (Grouping Method B through G, multi-Access function). Since the modem searches clear frequency in the group, it overcomes multipath fading and interference problems and establishes wireless communications. On the down side, wireless link establishment delays will become longer when using the frequency group function (multi-access function) because the additional time is required for searching the channels in the group with transmitting and receiving the packet on the both end of the modem. The average connection delay will increase and the number of systems that can operate independently in the same area will decrease as the number of frequencies per group increases. Select the best grouping method for your application. 3.5.3 Grouping Methods The frequency grouping method and group number are set using memory register REG06. Method Group Numbers Frequencies per Group A 0 to 75 1 B 0 to 37 2 C 0 to 24 3 D 0 to 18 4 E 0 to 11 6 F 0 to 8 8 G 0 to 5 12 Table 3–7: Frequency Grouping Methods and Group Numbers

214SECTION 4 FUNCTION CONTROL METHODS

22 4.1 Interface 4.1.1 Pin Assignment The figure below shows the pin location of the serial communication connector, following the DCE (Data Communication Equipment) specification. Figure 4–1: Serial Communication Connector Location Pin Name Abbreviation I/O Function 1 Carrier Detect Out DCDO output carrier detect output 2 Receive Data RxD output received data output 3 Transmit Data TxD input transmit data input 4 Data Terminal Ready DTR input terminal ready 5 Signal Ground GND – signal ground 6 Data Set Ready DSR output modem ready 7 Request To Send RTS input receive stop/resume request 8 Clear To Send CTS output transmit stop/resume request 9 Carrier Detect In DCDI input ring indicator input 10 Power Supply VCC – 2.7V to 3.3V DC 11 Modem Shutdown POWER_ON input Power On control 12 RS485 Enable 485ENB in/out RS485bus Tx Enable at 485mode 13 Load Default Parameter /INIT input Load default parameter when low 14 Reserved Reserved – Reserved Table 4–1: Pin Descriptions 1. The serial communication connector’s pin of the modem is defined as the DCE specification, where transmission indicates input and reception indicates output. 2. Pin 12 is for tri-state control for RS485 driver (CMOS - RS485 level converter) which will be externally mounted. When the power is turned on or reset, this pin is configured as an input pin to read the operation mode in the interface. When it is pulled down, the operation becomes the RS485 mode, and when it is pulled up (or leave open) the operation becomes the RS232C mode. Since this pin becomes to configure the output pin after reading the operation mode at the initialize state, never connect it directly to VCC or GND. This pin is internally pulled up with 470 k ohm. 3. Pin 13 is internally pulled up with 100 k ohm. 4. The input pin tolerates 5 V input (5 V tolerant specification). When the user’s system is of 5 V, it is possible to interface with a such system. # 1 # 14

235. Pin 11 can be used as the hardware reset. Since the input pin is at high impedance, never fail to tie the input level. 6. It is no problem if Pins 12, 13 and 14 are leaved open. 7. Since the interface is CMOS structure circuit, it is recommended to take a remedy against ESD problem (e.g. surge absorber; VRD series, made by Ishizuka Denki). 4.2 Serial Interface Setting For connecting the FDL01TU modem with an external terminal equipment, RS232C is appropriate for 1 to 1 topology. And set the RS485 mode to make RS485 multi-dropping topology for multiple equipment connection. Interface configuration can be made with Pin 12 (/RS485ENB) of the serial communication connector. To configure the RS485 mode, pull down Pin 12 with 10k ohm register. In this case, do NOT connect this pin DIRECTLY to the GND. This is because in RS485 mode, this pin will be as an output pin, after the initialization completes, to control the output buffer of the RS485 driver IC chip. As for the RS232C interface, no connection is required because it is pulled up inside. Since the interface level of the FDL01TU modem is CMOS, the level conversion circuit must be provided outside for connecting it with the RS232C or RS485 interface. For an example of the level conversion circuit, see p.64 CONVERSION CIRCUIT. Figure 4–1: Connection Example to PC Converter PC RS-232C FDL modem

244.3 Terminal Software Setup for Memory Register Control Communication or terminal software is necessary to set the memory registers. Nearly any PC communication software can be used. Launch the communication software and set the terminal’s communication parameters as shown below. Refer to your specific communication software instructions how to set these parameters. bit rate: 9600 bps data length: 8 bits stop bits: 1 bit parity bit: none flow control: none local echo: yes terminator: carriage return + line feed 4.4 Memory Register Setting Memory registers set the operation mode and communication parameters of the modem and retain them in memory. All of the settings of the modem are made by these memory registers. Since the memory register is based on rewritable non volatile memories, these memories can be readily rewritten by external terminal equipment such as PC and their contents will be kept even after the power is turned off. This non volatile memory can be rewritten about 1 million times. 4.4.1 Memory Register Referencing and Setting Memory registers are referenced and set with the REG command. (For more information, refer to REG section at p.43 COMMAND SET DESCRIPTION) Example procedure: 1. To view the current value of register 00, enter: @REG00 CR/LF 2. Modem responds with 00H CR/LF (REG00 is assumed to be 00H in this case and varies in each setting case) 3. To set register REG00 to 0FH, enter: @REG00:0FH CR/LF 4. Modem responds with “P0” CR/LF 5. Enter “@RST CR/LF” or cycle the modem power, to activate new values @ = command header (specify following characters are command) CR/LF = Terminator (carriage return + line feed) When rewriting the modem’s memory registers, do not turn the modem’s power off until the modem returns “P0” response. If the power is interrupted before “P0” is returned, the memory contents may be lost or corrupted and the modem operation will be unpredictable. CAUTION

25If the memory contents are lost or corrupted, they can be restored to original default settings by reinitializing them. (See the section below titled p.25 MEMORY REGISTER INITIALIZATION) Input character arrays of commands quickly and sequentially. Too slow input (taking more than 5 seconds in the initial setting) results in command error. 4.4.2 Memory Register Initialization The memory registers can be restored to the factory default values at any time by using one of the following two methods. 1) Memory Register Initialization by hardware: Use either methods stated below, in which the modem attempts to read Pin 13 (/DefParam) of the serial communication connector at the startup and starts initializing the memory registers when it is “L”. Method 1. Set “L” level to Pin 13 (/INIT) of the serial communication connector with the power turned off. When the power is re-supplied, the memory registers are initialized and the modem starts operation in the factory default state. Method 2. Set “L” level to Pin 13 (/INIT) of the serial communication connector while the power turned on. In this state, force “L” to Pin 11 (POWER ON) of the serial communication connector more than 1ms, then return the level to “H”. The modem once becomes the Shutdown mode and returns to Active mode. Since this sequence is the same as the reset, the memory registers are initialized and the modem starts operation in the factory default state. 2) Memory Register Initialization by Command: 1. With the modem power is on and the communication software running, enter “@INI CR/LF ” at the terminal prompt. 2. The modem responds with “P0” response and immediately begins to operate using the initialized factory default state. While initializing the memory registers, do not turn the modem’s power off. It take about 1 sec. to initialize the memory registers. CAUTIONCAUTION

264.5 Command Control Some FDL01TU parameters can be changed by issuing commands from the terminal equipment. Various applications can be supported with the flexibility that command control offers. Command Entry • When a command is issued to the modem from the terminal equipment, a command header (one byte character) should be used the modem to acknowledge the command from ordinary data. The command header is initially set to “@” (40H) but can be changed to another character by changing the value stored in the memory register REG10. • Commands must use all upper case letters (A to Z). The modem does not recognize lower case letters (a to z) in commands. • A two byte terminator (carriage return (0DH) + line feed (0AH)) is used to terminate a command. “CR/LF” shows the terminator in this manual. PC can send this two byte character with pressing ENTER key once using a communication software. But some setting is necessary in the software. • The modem immediately executes a command once it’s recognized. If the command requires a response, the modem returns the response to the terminal equipment when its internal processing is completed. The following is an example of a command entry and response: @BCL CR/LF :command issued from the terminal equipment P0 CR/LF : successive completion response is returned

275SECTION 5 MEMORY REGISTER DESCRIPTION

28 5.1 Memory Register Description The FDL01TU modem contains 28 memory registers which are used to control and store communication parameters and operation mode settings. After rewriting new register settings, the power must be cycled, a hardware reset asserted, or a software RST command is issued to validate the new settings. The following table briefly lists each register, register function and default value: Register Function Default Value Meaning REG00 Local Station Address 000 address 0 REG01 Local Station Group Address 240 address 240 REG02 Destination Address 000 address 0 REG03 Reserved F0 H F0H REG04 ID Code 1 00 H address 0 REG05 ID Code 2 00 H address 0 REG06 Frequency Group C00 see text REG07 Packet Interval 05 H 5 ms REG08 Repeater1 Address A00 not use REG09 Repeater2 Address A00 not use REG10 Command Header 40 H character @ REG11 Retransmission Count 32 H 50 count REG12 Roaming Threshold 50 H -80dBm REG13 Buufer Data Timeout 1E H 30 s REG14 Command Input Timeoutl 32 H 5 s REG15 Command Recognition Interval 00 H 0 s REG16 Terminator 1 0D H CR REG17 Terminator 2 0A H LF REG18 Communication Setting 1 8C H see text REG19 Communication Setting 2 00 H see text REG20 Serial Interface Setting 1 05 H see text REG21 Serial Interface Setting 2 09 H see text REG22 Serial Interface Setting 3 00 H see text REG23 Serial Interface Setting 4 00 H see text REG24 Miscellaneous Settings C0 H see text REG25 Miscellaneous Settings 40 H see text REG26 Data Input Timeout 00 H not use REG27 Reserved 00 H - Table 5–1: Memory Registers Suffix ‘H’ of each default value denotes HEX radix expression in the value.

29REG00: Local Station Address [default value: 000] • Sets the local station address. Valid values are 000 to 999. • This value is inserted in the “source address” field in the transmitted packet header. • If the address check function is enabled (REG18) in the receiving modem, the modem can receive the packet which header contains destination address information identical to REG00. REG01: Local Station Group Address [default value: 240] • Sets the local station global address of the modem. Valid values are 240 to 254. • When plural modems are connected by RS485 multi-dropping topology, commands can be issued to multiple modems simultaneously by setting all connected modems to the same group address. This is the group addressing. • This group addressing allows to handle multiple multi-dropped modems as if they were one modem. REG02: Destination Address [default value: 000] • This address is used in the data transpalent mode and headerless stream mode. • Valid values are 000 to A23(1023). REG03: Reserved [default value: F0H] • The FDL01TU does not use this register. Keep the default value as it is. REG04: ID Code 1 [default value: 00H] • Used with ID code 2 (REG05), set the ID code. Valid values are 000 to 255. Together with ID code 2, up to 65535 ID codes can be set. • The ID code identifies the group of the modems works in the same group. The ID code is used to prevent erroneous connection with other systems and for communication security. • Before transmission, radio data packets are scrambled using a pseudo-random data sequence generated with this ID code as the seed. During reception, the original data is restored by de-scrambling it with the pseudo-random data sequence. The modems with different ID codes cannot communicate with each other. REG05: ID Code 2 [default value: 00H] • Used with ID code 1 (REG04), set the ID code. Valid values are 000 to 255. Together with ID code 1, up to 65535 ID codes can be set. • In case plural modems are used as a single system, always set the same ID code for all modems and repeaters.

30REG06: Frequency Group [default value:C00] • Refer to p.18 FREQUENCY GROUPING in Section 3, for a detailed description of the frequency operation modes.

The default value is 5 ms. • Set this interval to a larger value than the receiving interval set by REG14. • Suitable setting of this interval avoids the data collision possibility of RS485 line. REG08: Repeater 1 Address [default value: A00] • When a repeater is used, set the repeater1 address to pass through. REG09: Repeater 2 Address [default value: A00] • When second repeater is used, set the repeater2 address to pass through. REG10: Command Header [default value: 40H] • Sets the character that identifies the start of a command. • The default is character “@” (40H). • When this character is input from the terminal equipment after no character is received for the command recognition interval (REG15) or longer, subsequent input character is recognized as a command for the modem.

31REG11: Retransmission Count [default value: 32H] • Sets the maximum number of packet retransmission attempts. Valid values are 000 to 255. • When retransmission exceeds the retransmission count (retransmission count plus one), the modem outputs an error response to the terminal equipment. REG12: Roaming Threshold [default value: 50H] • At the time to set the frequency roaming (REG19:bit 2 is 1), set the receiving strength threshold of the radio beacon which starts scanning frequency. • Set the value of the desired radio beacon strength threshold represented in dBm excluding the minus sign, e.g., set to “080” to search the next master station when the radio beacon strength becomes below –80 dBm. REG13: Buffer Data Timeout [default value: 1EH] • Valid values are 000 to 255, representing seconds in 1 s increments. REG14: Command Input Timeout [default value: 32H] • Sets the character input timeout interval for command input. It is used as the timeout between the command header and the character following it and between each character of the command. • At the timeout, the modem operation transits from command-input-state to data-wait-state. • Valid values are 000 to 255, representing tenths of seconds in 0.1 second increments. (Set an integer value equal to ten times the number of seconds desired.) • A setting of 000 disables this timeout function REG15: Command Recognition Interval [default value: 00H] • When a message data contains a command header character (in case of binary data or data in two-byte Chinese characters), data following the command header character will be interpreted as a command, the message does not transmit properly. • Sets the necessary vacant duration time interval to discriminate between ordinary data character and a command header character. Input a command after a longer interval than time interval setting. • Valid values are 0.1 to 25.4 sec., representing tenths of seconds in 0.1 second increments. (Set an integer value equal to ten times the number of seconds desired.) • When set to 000, the command header is recognized at any time, and when set to 255, all command header character are ignored.

32REG16: Terminator 1 [default value: 0DH] • Set an arbitrary 1 byte terminator. In case of a 2-byte terminator, set the first byte character of the terminator. REG17: Terminator 2 [default value: 0AH] • Set another arbitrary 1 byte terminator. In case of a 2-byte terminator, set the last character of the terminator . REG18: Communication Setting 1 [default value: 8CH] Bits 7 – 6: Protocol bit 7 bit 6 Setting 0 0 Data transpalent mode 0 1 Reserved 1 0 Packet transmission mode 1 1 Headerless stream mode Table 5–7: Protocol Bits 5: Reserved • The FDL01TU does not use this register.

Bit 3: Extended reception 0 Disable extended reception (default value) 1 Enable extended reception Table 5–9: Extended reception • Contention type communication in packet transmission mode (including the headerless stream mode) may cause repetitive retransmission when two modems are in transmission state in identical timing. This results in the decrease of response rate or the transmission failure. • This extend reception function solves such problems as above. The data packet received during carrier sensing are received first by interrupting the on-going transmission operation. Bit 2: Receiving frequency change 0 Regularly change frequency within a group while waiting (default value) 1 Fix the frequency to wait while data can be regularly received. Table 5–10: Receiving frequency change • Set the changing method of receiving frequency in packet transmission mode. Sets roaming function with combining bit 1. Bit 1: Beacon transmission 0 No transmission until transmission command is requested (default) 1 Enable regular beacon transmission. Table 5–11: Beacon Transmission • Enable or disenable beacon transmission in packet transmission mode. • Set roaming function with combining bit 2. Bit 0: Reserved • The FDL01TU does not use this register. Keep the default value as it is.

Bit 4: Command Header 0 Use REG 10 character 1 Use Break signal Table 5–16: Command Header Bit 1: Flow Control 0 Software flow control (default value) 1 Hardware flow control Table 5–18 Software/Hardware Flow Control Settings • Selects the flow control method. This setting must match the connected terminal equipment’s setting. • Hardware flow control uses the two control lines RTS and CTS. When using with the RS485 interface, be sure to set to 0. • Software flow control uses XON and XOFF codes. Bit 0: Flow Control 2 0 disable flow control 1 enable flow control Table 5–31: Flow Control 2 Settings • Enable or disable flow control between the terminal and FDL01TU modem connected through the RS-232C serial interface. • This function should normally be enabled, otherwise buffer overflow can occur and data may be lost. REG22: Serial Interface Setting 3 [default value: 00H] Bit 7: Enable and Disable Reception 0 Enable reception at the initial state (default value) 1 Disable reception at the initial state Table 5–19: Enable/Disable Reception • The initial state is in reception enable. Depending on an usage of the modem, the initial state of the modem may be better in the reception disable state. In such a case, use this setting.

37• Issue the REN command to enable reception. Bit 6: Reserved • The FDL01TU does not use this register. Keep the default value as it is. Bits 5 – 4: DCD (Data Carrier Detect) Bit 5 Bit 4 Setting 0 0 Ignore DCD input; DCD output always ON (default value) 0 1 Ignore DCD input; DCD output ON at connection, OFF at disconnection 1 0 Remote modem’s DCD (IN) is transferred to local modem DCD (OUT). (DCD Output = OFF at reset state) 1 1 Remote modem’s DCD (IN) is transferred to local modem DCD (OUT) (DCD Output = ON at reset state) Table 5–20: DCD Settings Bits 3 – 2: DTR/DSR Bit 3 Bit 2 Setting 0 0 Ignore DTR input; DSR output always ON (default value) 0 1 Ignore DTR input; DSR output ON at connection, OFF at disconnection 1 0 Remote modem DTR is transferred on local modem CTS (CTS = OFF at reset state) 1 1 Remote DTR is transferred on local modem CTS (CTS = ON at reset state) Table 5–21: DTR/DSR Control Settings Bits 1 – 0: Reserved • The FDL01TU does not use this register. Keep the default value as it is. REG23: Serial Interface Setting 4 [default value: 00H] Bit 7 : reserved • The FDL01TU does not use this register. Keep the default value as it is. Bit 6 : Transmission buffer clear 0 Data of the transmission buffer is kept after disconnection (default value) 1 Transmission buffer is cleared when the link is disconnected. Table 5–38 Transmission buffer clear • Determine to clear or not to clear data stored in the transmission buffer in the data transparent mode when the link is reconnected. Bit 5 : reserved • The FDL01TU does not use this register. Keep the default value as it is.

38 Bit 4 : CR/LF addition/deletion (1) Setting at the headerless stream mode 0 does not add CR/LF code to the received data (default value) 1 adds CR/LF code to the received data Table 7–6: Addition of CR/LF code • In the headerless stream mode, setting is made whether the CR/LF character is added to the received data or not. • In the communication between the modems set to the headerless packet mode, this setting is invalid because the terminator is originally added to the transmit data. However, when a packet is received from the modem in the packet transmission mode, there is no addition of the CR/LF terminator. In this case, set this bit to 1. Then the received packet is output with the CR/LF character is added. (2) Setting at the packet transmission mode 0 adds the CR/LF to the received data (default value) 1 does not add the CR/LF to the received data Table 7–7: Deletion of CR/LF character • In the packet transmission mode, setting is made whether the CR/LF character is added to the received data or not. • At the receiver modem (set to the packet transmission mode), the sender (set to the headerless stream mode) side terminator (CR/LF character as default) plus packet transmission mode terminator (CR/LF) are output. To avoid such redundant outputs, set this bit of the modem in the normal packet transmission mode to 1. Bit 3: reserved • The FDL01TU does not use this register. Keep the default value as it is. Bit 2: RS485 collision avoidance regular interval output 0 No C/R code output for collision avoidance (default value) 1 Regularly output C/R code for collision avoidance Table 5–23: C/R Code Regular Interval Output • Sets whether the collision avoidance function is used or not, together with bit 1. • When this bit is set to 1, responses or data will be output to RS485 line if there are such responses or data exist in the buffer at the timeout of the RS485 Packet Interval (REG07). If there are no such responses or data exist in the buffer, the C/R code (0Dh) is compulsorily output. • The effective use of this function helps to shift the output timing of multi-dropped modems on RS485 line. Eventually it avoids the data collision on the RS485 line.

39• To use this function, set REG23:bit 1 of all RS485 multi-dropped modems to 1. And set all the RS485 Packet Interval (REG07) to different values more than 1.5 bytes each. Further set this bit of the modem, the RS485 Packet Interval is set to the longest, to 1. Bit 1: RS485 collision avoidance 0 Invalid collision avoidance function (default value) 1 Use collision avoidance function Table 5–24: Collision Avoidance Function • Sets to decide whether to use the collision avoidance function or not, together with bit 2. • When modem tried to output a response or the received data, the modem outputs only if RS485 line is available at the timeout of RS485 Packets Interval (REG07). When RS485 line is not available at the timeout, the modem waits for a line becomes available and starts re-measurement of its packet interval. • Set to 1 makes it unable to output neither response nor the received data, unless other modem(s) outputs any data to the RS485 line and interval time measuring becomes effect. • Bit 2 is used for the purpose of resolving this problem. Bit 0: Global addressing command response 0 No P0 response to global addressing command (default value) 1 Respond P0 response to global addressing command Table 5–25: Global addressing command response • Set to decide whether to return “P0” response (including “P1” for the transmit command) to the terminal equipment for the global addressing command (commands for Addresses 240 to 254). • When the global addressing command is issued to plural modems, which are multi-dropped and have the same global address on RS485 line, there is a possibility causing data collision on the RS485 line. Unless the RS485 Packet Interval is properly set. This is because all modems return the “P0” (or P1) response to the terminal equipment simultaneously on default memory setting. Such potential problem can be avoided by limiting the modem to output the response to the global addressing command is only one.

Response P0 : command accepted N0 : command error (Except 485 mode) Function On headerless stream mode , clears the contents of the transmit and receive buffers of the modem. Example >@BCL CR/LF : clear the buffer contents <P0 CR/LF : command accepted Example >@BIV025 CR/LF : Set the receiving (transmission) interval at 250 ms <P0 CR/LF : command accepted >@BIV CR/LF : Refer the current value <025 CR/LF : 025 (25 0ms) returns Notes Values set by the BIV command will be lost by turning the power on or resetting. Generally, this parameter is no need to modifying. Use with the default value.

46CON Connect Wireless Link Syntax CON(destination address) destination address : 000 to 999 Response P0 : connection established P1 : command received, link established N0 : command error N1 : connection failed – no response from destination modem N4 : connection failed – local modem already connected to a remote modem. Function Requests a wireless link connection to the remote modem in data transparent mode. If this command is input with no destination address parameter, the destination will be the address that was set with the REG02. If the destination address is input, change the destination address to connect the wireless. Example >@DAS002 ↵ : set the destination address to 002 <P0 ↵ : connection established >@CON ↵ : request wireless connection remote station 002 <P1 ↵ : connecting… <P0 ↵ : connection established (Time-Division-Duplex communication between terminals is established.) >@DCN ↵ : request disconnection of the wireless link <P1 ↵ : disconnecting… <P0 ↵ : connection established >@CON003 ↵ : request wireless connection to remote station 003 <P1 ↵ : connecting… <P0 ↵ : connection established >@CON004 ↵ : request wireless connection to remote station 004 <N4 ↵ : local modem already connected to a remote modem Notes If this command is input to designate the destination address, the destination address set with the DAS command will be changed to set the address designated with this command to the designation address. DAS Reference and Set Destination Address Syntax DAS(set destination address) set destination address : the desired destination address (000 to A23)

47Response xxx : current value (reference) P0 : command accepted (setting) N0 : command error Function References or sets the destination address of the modem connection established with in the data transparent mode and headerless stream mode The current DAS value can be referenced by entering the command with no parameter. The DAS command is used for temporary modifying destination address. Change the value of REG02 to change the default value. Example >@DAS002 CR/LF : set the destination address to 002 <P0 CR/LF : command accepted >@DAS CR/LF : reference the destination address <002 CR/LF : current value output (002) Notes This command cannot be used in packet transmission mode. The local station address (REG00) must be set to communicate with the remote modem. Communication cannot be established unless the addresses coincide with each other. This command is not arrowed to use in 485 mode. DBM Read Signal Strength Syntax DBM{Local Station Address} Local Station Address : local station address for 485 mode (000 to 999). Response -xxxdBm : signal strength N0 : command error (Except 485 mode) Function Reads the received signal strength and outputs the value in dBm. Higher values represent stronger signal strength and better receiving conditions. Example >@DBM CR/LF : read signal strength <-78dBm CR/LF : signal strength is -78dBm. Notes The range available for measurement is –40 dBm to –100 dBm. Since the signal strength indication has a slight error in its value, use this result for your ‘rule of a thumb’ reference. This command outputs the strength of last received packet.

48DCN Disconnect Wireless Link Syntax DCN Response P0 : connection established P1 : command received, link disconnected N0 : command error N1 : link disconnect failed N4 : link is disconnected Function In data transparent mode, this command requests wireless disconnection from the remote modem. Example >@CON002 ↵ : request wireless connection to station 002 <P1 ↵ : connecting… <P0 ↵ : connection established (Time-Division-Duplex communication between terminals is established.) >@DCN ↵ : request disconnection of the wireless link <P1 ↵ : disconnecting… <P0 ↵ : connection established >@DCN ↵ : request disconnection of the wireless link <N4 ↵ : link is disconnected FRQ Reference and Set Frequency Group Syntax FRQ(:frequency group){Local Station Address} frequency group : combination of frequency grouping method (A to H) and group number (00 to 75). See p.18 FREQUENCY GROUPING more details. Local Station Address : local station address for 485 mode (000 to A22) . Response xxx : current value P0 : command accepted N0 : command error (Except 485 mode) Function References or sets the frequency grouping method and group number. The current set value is referenced by omitting the “:frequency group” parameter This command is for temporary use only. To change the default value, change the settings of REG06.

49Example >@FRQ CR/LF : reference the current grouping method and frequency number <F00 CR/LF : output current value (grouping method F: group number 00) >@FRQ:E03 CR/LF : set grouping method to E (6 groups) and group number to 3. <P0 CR/LF : command accepted Method Group Numbers Frequencies per Group A 0 to 75 1 B 0 to 37 2 C 0 to 24 3 D 0 to 18 4 E 0 to 11 6 F 0 to 8 8 G 0 to 5 12 Table 3–7: Frequency Grouping Methods and Group Numbers Notes Do not change this setting while the modem is being transmitted. The maximum number of frequency groups available depends upon the selected grouping method. INI Initialize All Memory Registers Syntax INI{Local Station Address} Local Station Address : local station address for 485 mode (000 to A22). Response P0 : command accepted N0 : command error (Except 485 mode) Function Sets the all contents of the memory registers to the factory default values. Example >@INI CR/LF : initialize all memory registers <P0 CR/LF : command accepted Notes Custom settings of all memory registers are lost when this command is executed.

50 If the group address (REG01) is designated while RS485 multi-drop connection is being made in the RS485 mode, the local station address of all modems will be initialized to 000. Exercise care when issuing this command. For a list of the factory default values, see the section titled p.27 MEMORY REGISTER DESCRIPTION. ODA Disable Received Data Output Syntax ODA{Local Station Address} Local Station Address : local station address for 485 mode (000 to A22). Response P0 : command accepted N0 : command error (Except 485 mode) Function Disables output of any data received via the wireless link to the terminal equipment. Data received, while output is disabled, is stored in the receive buffer. When the modem’s power is turned on (or a reset), the modem is in the state to enable the received data output. Example >@ODA CR/LF : disable the output of received wireless data <P0 CR/LF : command accepted (Data is not output during this period even if received.) >@OEN CR/LF : enable the output of received wireless data. <P0 CR/LF : command accepted <RXT002HELLO CR/LF : outputs data stored in the receive buffer <RXT003MAIL CR/LF : OEN Enable Received Data Output Syntax OEN{Local Station Address} Local Station Address : local station address for 485 mode (000 to A22). Response P0 : command accepted N0 : command error (Except 485 mode) Function Enables output of any data received via the wireless link to the terminal equipment.

51 This command enables serial data output after it has been disabled with the ODA command. When the modem’s power is turned on (or a reset), the modem is in the state to enable the received data output. Example >@ODA CR/LF : disable serial output of received wireless data <P0 CR/LF : command accepted (Data is not output during this period even if received.) >@OEN CR/LF : enable serial output of received wireless data. <P0 CR/LF : command accepted <RXT002HELLO CR/LF : outputs data stored in receive buffer <RXT003MAIL CR/LF : and any new data received PAS Reference and Set Repeater Address Syntax PAS (:Repeater Address1 :Repeater Address2) Repeater Address : repeater address to pass through Response xxx : xxx : current address (reference) P0 : command accepted (setting) N0 : command error Function In the headerless stream mode , references and sets the repeater address to pass through When no repeater address is set, the current setting can be referenced. This command is used to temporarily change repeater address. To change the default value, change REG13. Example >@PAS CR/LF : references the current repeater address <004 : A00 CR/LF : current repeater address is 004 <P0 CR/LF : command accepted < @PAS:002:A00 CR/LF : sets the repeater address to 002 <P0 CR/LF : command accepted Notes This command is not allowed to be used in 485 mode.

52RDA Disable Wireless Reception Syntax RDA{Local Station Address} Local Station Address : local station address for 485 mode (000 to A22). Response P0 : command accepted N0 : command error (Except 485 mode) Function Disables wireless reception in the packet transmission mode. The status when the modem is powered ON or reset follows bit 7 of REG22. Example >@RDA CR/LF : disable wireless reception <P0 CR/LF : command accepted >@REN CR/LF : enable wireless reception <P0 CR/LF : command accepted REG Reference and Set Memory Register Syntax REG[register number](: value) {;Local Station Address} register number : register number to be set (00 to 27) value : value to be set. Input 2 hexadecimal digits (0 through 9 and A through F) followed by the number radix designator H. Local Station Address : local station address for 485 mode (000 to A22 ). Response xxx : current value (reference) P0 : command accepted (setting) N0 : command error (Except 485 mode) N6 : memory register write error Function References or sets memory registers. The current register value is referenced by omitting the “value” parameter. Example >@REG00 CR/LF : reference the contents of register 00 <01H CR/LF : displays current value >@REG00 : 023 CR/LF : set value of memory register 00 to 023 (decimal) <P0 CR/LF : command accepted Notes The register can be rewritten sequentially. However, to make its parameter valid after rewriting it, re-supply the power, reset the modem or use RST command.

53While rewriting the memory register, do not turn off the power until response is output. Otherwise, the memory registers content may be collapsed. When the response of the memory register write error is output, set the values after initializing the memory register. REN Reception Enable Syntax REN{Local Station Address} Local Station Address : local station address for 485 mode (000 to A22). Response P0 : command accepted N0 : command error (Except 485 mode) Function Enables wireless reception in the packet transmission mode. The status when the modem is powered ON or reset follows bit 7 of REG22. Use this command to enable wireless reception after reception is disabled with the RDA command. Example >@RDA CR/LF : disable wireless reception <P0 CR/LF : command accepted >@REN CR/LF : enable wireless reception. <P0 CR/LF : command accepted RID Display Received Serial ID Syntax RID{Local Station Address} Local Station Address : local station address for 485 mode (000 to 999). Response XXXXXXXXXXXX : displays the received serial ID code（12 digits） N0 : command error (Except 485 mode) Function Outputs the serial ID code in the received packet and displays it. The serial ID code consists of 12 digits; upper three digits are 0 and the lower 9 digits are the product serial number of the transmitted-end modem. Be noted that the serial ID code of the packet received last is displayed. When packets are received from multiple stations and their data are stored in the receiving buffer, those data may not be correspond to the serial ID code readout with RID command.

54To use it more securely, it is recommended to readout the local serial ID code with TID command and pad it (either all or a part of it) in the transmitting packet. When no packet is received, “All Zero” is displayed as the result of this command execution. The serial ID code is no relation with ID code setting of REG04 and 05. Example >@RID CR/LF : requests the received remote station’s serial ID code < XXXXXXXXXXXX CR/LF :outputs the received remote station’s serial ID code RNO Reference and Set Retransmission Count Syntax RNO (:Retransmission count) {; Local Station Address} Retransmission count : maximum number of retransmissions (000 to 255) Local Station Address : local station address for 485 mode (000 to A22). Response xxx : current set value P0 : command accepted N0 : command error (Except 485 mode) Function This command references or sets the number of retransmissions (retransmission count) to attempt before making decision as transmission failure. The current value can be referenced by issuing the command with no parameter. RNO command is used to temporarily change the retransmission count. To change the default value, change the setting of REG11. Example >@RNO CR/LF : reference the retransmission count <050 CR/LF : output the current set value (50 times) >@RNO010 CR/LF : set the retransmission count to 10 times <P0 CR/LF : command accepted ROF RF Circuit Block Power Down Syntax ROF{Local Station Address} Local Station Address : local station address for 485 mode (000 to A22). Response P0 : command accepted N0 : command error (Except 485 mode) Function Turn off the power of RF circuit block and stops RF operation.

55This function is used to save the current consumption when no transmit/receive are required. Example >@ROF CR/LF : turn off RF circuit block <P0 CR/LF : command accepted >@RON CR/LF : turn on RF circuit block <P0 CR/LF : command accepted RON RF Circuit Block Power Up Syntax ROF{Local Station Address} Local Station Address : local station address for 485 mode (000 to A22). Response P0 : command accepted N0 : command error (Except 485 mode) Function Turn on the power of RF circuit block and activates RF operation. Use this command to activate RF circuit block after its power down state set by the ROF command. The status when the modem is powered ON or reset, the RF circuit block is in the operation state. Example >@ROF CR/LF : turn off RF circuit block <P0 CR/LF : command accepted >@RON CR/LF : turn on RF circuit block <P0 CR/LF : command accepted RST Reset Syntax RST{Local Station Address} Local Station Address : local station address for 485 mode (000 to A22). Response P0 : command accepted N0 : command error (Except 485 mode) Function Resets the modem to restore the power on state. When any memory register is rewritten with REG command before issuing this command, the value rewritten becomes valid and active. Temporary settings like DAS and FRQ command become invalid and the memory register settings is loaded.

56Example >@RST CR/LF : reset the modem <P0 CR/LF : command accepted Note When a serial communication parameter in memory register is changed with REG command, the response of “P0” returns according to the changed setting parameter, which may cause communication error. In such a case, set the communication parameter of the terminal equipment in correspondence with the new setting immediately after the issuance of RST command. SAS Reference and Set Local Station Address Syntax SAS (:set value){Local Station Address} set value : new local station address (000 to 999) Local Station Address : local station address for 485 mode (000 to 999). Response xxx : current value (reference) P0 : connection established (setting) N0 : command error Function References or sets the local station address. The current value can be referenced by entering this command with no parameter. For setting, input the desired value to set. The SAS command is for temporary local address and setting. To more permanently change the local station address value, use REG00. Example >@SAS001 ↵ : set the station address to 001 <P0 ↵ : connection established >@SAS ↵ : reference the local station address <001 ↵ : output the current value (001) STS Read Status Syntax STS{Local Station Address} Local Station Address : local station address for 485 mode (000 to 999). Response xxxxxxxx : modem’s current status (x = 0 or 1) N0 : command error (Except 485 mode) Function Reads the modem status register. (Represented with an 8-bit binary number.)

57X X X X X X X X Status Bit Name 1 0 0 Connection Connected Disconnected 1 Reception Disabled Enabled 2 Output message Disabled Enabled 3 Receive buffer Data exist Data empty 4 Transmit buffer Data exist Data empty 5 Reserved - - 6 Reserved - - 7 Reserved - - Figure 6–2: Modem Status Bit Description Example >@STS CR/LF : read the current status <00001010 CR/LF : Received data exist, Output message enabled, Reseption disabled ,Disconnected. TBN Transmit Binary Data Syntax TBN[destination address][message byte length]{Local Station Address}[message] Destination address : address of the transmission (000 to A23) Message byte length : message length (001 to 255) Local Station Address : local station address for 485 mode (000 to A22). Message byte : arbitrary binary data (255 or less) Response P0 : data transmission succeeded P1 : command accepted, data being transmitted N0 : command error (Except 485 mode) N1 : data transmission failed -- no response from destination station N2 : data transmission failed -- destination station is in the reception disabled state N3 : data transmission failed -- destination station cannot receive because its receive buffer is full Function Transmits binary data in the packet transmission mode. Any message length between 1 to 255 bytes is accepted. The modem counts the number of message characters and transmits the message. For broadcasting messages to multiple modems, set the destination address to 255. In this case, the modem retransmits the message the number of times of the Retransmission count plus 1, and then it will return “P0”. In case the global addressing command is issued to plural modems connected by RS485 multi-dropping interface, the transmission stops when any modem outputs “P0”, “N2” or “N3” response to the RS485 line. Example >TBN002005HELLO CR/LF : transmit “HELLO” from station 001 to station 002 <P1 CR/LF : data being transmitted <P0 CR/LF : data transmission succeeded. >@TBN003004MAIL CR/LF : retransmit “MAIL” from station 001 to station 003

58 <P1 CR/LF : data being transmitted <N1 CR/LF : transmission failed, no response from destination station Notes Set the message length to 255 byte or less. The message length exceeding 255 byte will be command error. Message must be terminated with 2 byte (CR/LF) character, others will be command error. In broadcast transmission, the receiving result of the destination station cannot be confirmed at the sender side. TBR Transmit Binary Data through Repeater Syntax TBR [repeater address] [destination address] [message byte length]{Local Station Address}[message] Repeater address : repeater address to pass through (000 to 999) Destination address : address of destination station (000 to A23) Message byte length : message byte length (001 to 255) Local Station Address : local station address for 485 mode (000 to A22). Message byte : arbitrary binary data (255 or less) Response P0 : data transmission succeeded P1 : command accepted, data being transmitted P2 : data packet reached to repeater N0 : command error (Except 485 mode) N1 : data transmission failed -- no response from destination station N2 : data transmission failed -- destination station is in the reception disabled state N3 : data transmission failed -- destination station cannot receive because its receive buffer is full Function In the packet transmission mode, transmits binary data through repeater. Any message length between 1 to 255 bytes is accepted. The modem counts the number of message characters and transmits the message. For broadcasting messages to multiple modems, set the destination address to 255. In this case, the modem retransmits the message the number of times of the Retransmission count plus 1, and then it will return “P0”. In case the global addressing command is issued to plural modems connected by RS485 multi-dropping interface, the transmission stops when any modem outputs “P0”, “N2” or “N3” response to the RS485 line. Example >TBR100002005HELLO CR/LF : transmit “HELLO” from station 001 to station 002 <P1 CR/LF : data being transmitted <P2 CR/LF : data packet reached to repeater <P0 CR/LF : data transmission succeeded Notes Set the message length to 255 byte or less. The message length exceeding 255 byte will be command error. Message must be terminated with 2 byte (CR/LF) character, others will be command error. In broadcast transmission, the receiving result of the destination station cannot be confirmed at the sender side.

59TID Display Local Station Serial ID Syntax TID{Local Station Address} Local Station Address : local station address for 485 mode (000 to 999). Response XXXXXXXXXXXX : displays the local serial ID code (12 digits) N0 : command error (Except 485 mode) Function Readout the local serial ID code of the modem and display it. This command corresponds to RID command. The local serial ID code consists of 12 digits; upper three digits are 0 and the lower 9 digits are the product serial number of the modem. Be noted the usage of RID command, the serial ID code of the packet received last is displayed. When packets are received from multiple stations and their data are stored in the receiving buffer, those data may not correspond to the serial ID code readout with the RID command. To use it more securely, it is recommended to readout the local serial ID code with the TID command and pad it (either all or a part of it) in the transmitting packet. The serial ID code is no relation with ID code setting of REG04 and 05. Example >@TID CR/LF : requests the modem’s local serial ID code < XXXXXXXXXXXX CR/LF :outputs the modem’s local serial ID code TXR Transmit Text Data through Repeater Syntax TXR [repeater address] [destination address]{Local Station Address}[message] repeater address : address of repeater to pass through (000 to 999) destination address : address of destination station (000 to A23) Local Station Address : local station address for 485 mode (000 to A22). message : any text data (255 or less) Response P0 : data transmission succeeded P1 : command accepted, data being transmitted P2 : data packet reached to repeater N0 : command error (Except 485 mode) N1 : data transmission failed -- no response from the destination station N2 : data transmission failed -- destination station is in the reception disabled state N3 : data transmission failed -- destination station cannot receive because its receive buffer is full. Function Transmits text data in the packet transmission mode through repeater. Any message length between 1 to 255 bytes is accepted. The completion of data input is recognized by the terminator.

60 For broadcasting messages to multiple modems, set the destination address to 255. In this case, the modem retransmits the message the number of times of the Retransmission count plus 1, and then it will return “P0”. In case the global addressing command is issued to plural modems connected by RS485 multi-dropping interface, the transmission stops when any modem outputs “P0”, “N2” or “N3” response to the RS485 line. Example >@TXR100002HELLO CR/LF : transmits HELLO from station 001 to station 002 through repeater 100 <P1 CR/LF : data being transmitted <P2 CR/LF : data packet reached to repeater <P0 CR/LF : data transmission succeeded Notes Set the message length to 255 byte or less. The message length exceeding 255 byte will be command error. When the same character as the terminator (CR/LF) is contained in a message, the modem distinguishes it as the end of a command and ignore the subsequent data. In such a case, use TBR command. In broadcast transmission, the receiving result of the destination station cannot be confirmed at the sender side. TXT Transmit Text Data Syntax TXT [destination address]{Local Station Address}[message] destination address : address of destination station (000 to A23) Local Station Address : local station address for 485 mode (000 to A22). message : any text data (255 or less) Response P0 : data transmission succeeded P1 : command accepted, data being transmitted N0 : command error (Except 485 mode) N1 : data transmission failed - no response from the destination station N2 : data transmission failed - destination station is in the reception disabled state N3 : data transmission failed – destination station cannot receive because its receive buffer is full. Function Transmits text data in the packet transmission mode. Any message length between 1 to 255 bytes is accepted. The completion of data input is recognized by the terminator (CR/LF). For broadcasting messages to multiple modems, set the destination address to 255. In this case, the modem will retransmit the message the number of times of the Retransmission count plus 1, and then it will return “P0”. In case the global addressing command is issued to plural modems connected by RS485 multi-dropping interface, the transmission stops when any modem outputs “P0”, “N2” or “N3” response to the RS485 line. Example >@TXT002HELLO CR/LF : transmits HELLO from station 001 to station 002 <P1 CR/LF : data being transmitted

61 <P0 CR/LF : data transmission succeeded >@TXT003MAIL CR/LF : transmits MAIL from station 001 to station 003 <P1 CR/LF : data being transmitted <N1 CR/LF : transmission failed. no response from destination station Notes Set the message length to 255 byte or less. The message length exceeding 255 byte will be command error. When the same character as the terminator (CR/LF) is contained in a message, the modem distinguishes it as the end of a command and ignores the subsequent data. In such a case, use TBN command. In broadcast transmission, the receiving result of the destination station cannot be confirmed at the sender side. VER Reference Version Information Syntax VER{Local Station Address} Local Station Address : local station address for 485 mode (000 to 999). Response Program Version x.xxx :Hardware system version N0 : command error (Except 485 mode) Function Reads the modem’s hardware system version.
