Communication command Input and output between external control equipment and mobile stations are carried out by packet method. The data format of the packet method is either in the sequence of "@TXT ( address) (user data) [CR][LF]" or in the sequence of "@TBN ( address) (data length) (user data)" Binary data method is useful to avoid communication errors when a control code matches exactly a part of user data. @TXT (address) (user data) [CR][LF] Text data Address : ASCII code, hexadecimal 3-digits (For instance, 4 is "34h" in ASCII.) Data : ASCII code, hexadecimal The data length : Arbitrary but no more than 1024 bytes. [CR] : 0Dh in hexadecimal [LF] : 0Ah in hexadecimal Example : Sending "ABCDEFG" to a mobile station whose address is 400. @TXT400ABCDEFG[ CR][LF] Binary data @TBN (address) (data length) (user data) Address Data length [CR][LF] : ASCII code, hexadecimal 3-digits : "001" to "400" (0 to 1024 bytes) The number of bytes should be expressed by hexadecimal 3-digits in ASCII code. : not necessary If data length is longer than predetermined data length, the surplus of the data will slide in front of the next instruction. Therefore "NG[ CR][LF]" may be returned to the data sender. Example : Sending 7 bytes of binary data to a mobile station whose address is 400. @TBN400007 ( 7 bytes of binary data) Taking into consideration the manual input through terminal software, the text data method can delete a character by recognizing backspace key while the binary data method treats backspace key as data. In the communication between the feeder cable and mobile stations, a packet is defined and transmitted as the number of user bytes that are set by bit2 and bit3 of the DIP SW2. In the case that transmission and reception of all the data is completed properly, the sender will output the FUTABA p.10 Ni04-008-1 rev 4.0 message "OK [ CR][LF]" after receiving ACK of the last packet. On the other hand, the receiver will output the same character string that was sent from the sender from the headfirst. In case of @TBN command, the receiver will output the data that is within the range determined by the user data length, otherwise surplus of the data will not be outputted. In case of communication error, if ACK is not returned from the destination after repeating retransmission up to the preset number, the sender will stop sending data and output "NG [ CR][LF]" immediately after detection of the end of input data. In case of failure while sending a packet due to communication error, the sender will output the partial data that the sender could properly receive from the external interface of the receiver. 7. Control command Control commands are used for controlling the fixed station. Command table No. Command string FRQ PNG SWR RST COP 1 2 3 4 5 content Write or read frequency channel number Request response & read the reception intensity of the destination Read switch information Reset software Setting of the coupler or readout @FRQ : Write or read frequency channel number 1) Input : @FRQpp[ CR][LF] pp : Input a number between 1 and 50 ( ASCII code) or input nothing for pp. (note) Inputting a single digit is allowed for 1 through 9. Do not input space between "FRQ" and "pp". 2) Processing : If there is no input for "pp", the current frequency channel number will be outputted. Response message FRQ = pp[CR][LF] (note) pp : 01 to 50 ( ASCII code) Spaces are necessary in front of and afterwards of "=". : If a channel number is inputted in "pp", this modem will return "OK" message to the host computer after changing the SRAM register and reassign the frequency number,. 3) Frequency channel at the booting At the booting this modem and resetting the software, the frequency channel is given by the setting by SW5 on the case top. FUTABA p.11 Ni04-008-1 rev 4.0 @PNG : Request response & read the reception intensity of the destination 1) Input : @PNG[CR][LF] 2) Processing : Receiving this command, this modem returns as a response message the signal intensity of the last packet that this modem has received. Response massage RSSI = nn[ CR][LF] nn : Hexadecimal number of signal intensity in [ dBm] @SWR : Read switch information 1) Input : @SWR[CR][LF] 2) Processing : Receiving this command, this modem outputs information related to its switches of SW2 through SW5. SW1 has no function to send its information. SW2 : Binary, 8 digits ( 0: OFF, 1:ON BIT8 is in the far left.) SW3 : Binary, 8 digits ( 0: OFF, 1:ON BIT8 is in the far left.) SW4 : Hexadecimal, 2 digits ( The lower 2 digits of address) SW5 : Hexadecimal, 2 digits In case of the fixed station, this figure shows the setting condition of its channel switches. The most significant digit of the mobile station address corresponds to the rotary switch in the far right of the SW5. @RST : Reset software 1) Input : @RST[CR][LF] 2) Processing : Receiving this command, software will be reset. This command restarts the exerciser program from the start address. Also the SRAM register will be reset to the condition when this modem was turned on. In addition, this command will initialize not only the software but also the hardware of this modem. It takes about 300ms. After the completion of initialization, a response message of "OK" will be returned to the host computer. @COP 1) Input : Setting of the coupler or readout ( valid only for mobile stations) : @COPp[CR][LF] "p" should be 1 or 2 in ASCII code, or enter nothing. Do not input space between "COP" and "p". 2) Processing : in case of no value for "p"; The current status of the coupler is read out. The message will be; COP = p[CR][LF] p= 1 or 2 in ASCII code A space code ( 0x20) will be added to either side of the "=". FUTABA p.12 Ni04-008-1 rev 4.0 : In case that some value is inputted for "p": Coupler units will be switched. 3) Default setting COP = 1 4) Timing of command execution Receiving a command from external I/F, the mobile terminal will carry out the command and return its end message immediately after the disconnection of the coupler is completed. This command will be carried out regardless of the communication status on the feeder. 8. Address The effective addresses for mobile stations are from 400 trough 9FF. Use rotary switch SW4 for setting. Set the address at "001" when sending data to the fixed station from mobile stations. The address setting of the fixed station is required only for the host computer to send control command to the specific one of the fixed stations that is connected in multi-drop fashion. No specific address is necessary in case sending data from mobile stations, because there exits only one fixed station. 9. Communication with mobile stations Communication procedure ( an example) ① ② ③ ④ ⑤ ⑥ ⑦ Set parameters of fixed station, and make it effective to communicate with mobile stations. Connect to the power source. Connect the external interface ( One of RS-232C, RS422 and RS485) Connect to the matching/distributing unit. (The order between ② and ④ can be changed freely.) Turn on the fixed station and mobile stations. (The order to turn on the powers is free.) Wait more than 1 second and then set frequency channel. After receiving a response of "OK", forward to the next step. Send command/data in format of @TXT or @TBN. If "OK" is returned, the communication is completed. If "NG" is returned, possible reasons of the failure are insufficient signal strength and improper settings of communication cable, switches and frequencies. Send @PNG command and read the value of RSSI. If the value is 57 or lager, please confirm the setting condition again. If "OK" is returned, it is possible to continue communication by repeating ⑦ .
