QTI Page 3 of 13 Revision: A Form #: 30Z0250 Effective Date: 16 December 2009 Section 1: MCDT Multi-Channel Data Transceiver Description The Multi-Channel Data Transceiver (MCDT) is available as a modular modem to OEM users who want to design it into their own equipment. Equipped with RS-485 communications, the MCDT can be set up using a personal computer. The MCDT is capable of transmitting or receiving SEIWG-5 data messages, including a status code and distinct ID, over a radio frequency. This frequency is selectable via synthesizer control circuits, providing a selection of up to 1920 RF channels, depending on the model’s frequency range. The MCDT comes in Low-Band, Medium-Band, and High-Band models, having the following frequency ranges: Low Band Medium Band High Band Channel 001 = 138.025 MHz Channel 001 = 154.005 MHz Channel 001 = 162.00625 MHz Channel 600 = 153.000 MHz Channel 1600 = 162.000 MHz Channel 1920 = 174.000 MHz Antenna: MMCX plug to accept user-supplied antenna Power Supply: User-supplied, 4.8V to 16.5VDC nominal, 18 VDC absolute maximum Connections: Current Draw approximations: Mode Current Comments Sleep 33uA RS485 command will wake unit up Active 7.0mA Receiver Off / Microprocessor On Transmission(1Watt) 57ms @ 1.5A Pulse Current Provided by Super Caps Transmission(2Watt) 57ms @ 3A Pulse Current Provided by Super Caps Receiver On 12.6mA Receiver On – Waiting for valid RF message Receiver Active 16.9mA RF message received – Microprocessor On Design Features ID Code Selection 000-999 for EMIDS, 000-063 for all other formats Directional, sensor fault, low battery, tamper, and test status codes for EMIDS format Able to receive and transmit MIDS 20-bit, MMIDS / EMIDS 29-bit messages, TRSS, or REMBASS MMCX antenna port matched to 50 ohms Conformal-coated and shielded circuit assembly Operation Connections to the MCDT can be made using a ribbon cable connected to J1 or using flying leads soldered directly to the VIAS. See Connections table above to determine pin outs. Using the settings provided in Section 3: Serial Interface, open a serial communication program such as HyperTerminal and supply power to the MCDT. Upon establishing a connection to the MCDT, the computer screen will display “BL<LF><CR>” for one second and then display the version information. This indicates a ready status. The “BL” (Boot Loader) response provides for one (1) second the opportunity to enter the programming mode. Sending a “P” will enter the firmware upgrade mode and erase the firmware of the device. Therefore, the user is advised not to send any characters to the unit, especially not the character “P”, to the unit before the version information is received.

QTI Page 4 of 13 Revision: A Form #: 30Z0250 Effective Date: 16 December 2009 Section 2: MCDT Operation During normal operation, the MCDT is capable of sending and receiving SEIWG-5 messages via the serial port and via radio frequency. The MCDT assumes a low-power shut-down mode to conserve power when not in use. Receiving/Transmitting ITEMS REQUIRED 1. DC Power Source: 4.8 to 16.5 Volts 2. Personal Computer with COM port (RS-232 or USB) 3. RS-485 Adapter Cable to convert RS-485 to PC’s COM port format 4. Serial Communications Program such as HyperTerminal SETUP 1. Set the Channel. (Default CHR 001) 2. Enable receiver, if desired. Transmit is always enabled. (Default RCV ON) 3. Enable TRSS format, or disable TRSS for EMIDS format. (Default TRSS OFF) 4. Enable Push to send messages out serial port, or disable PUSH to poll for messages. (Default PUSH ON) RF Link The operational range of the RF link is dependent upon various conditions. The high frequency of the RF link works best under line of sight conditions. RF range may vary from 0.5 kilometer to 5 kilometers for open areas using the 1-Watt setting. Greater range may be expected using the 2-Watt setting. NOTE: Elevating an antenna will increase transmission and/or reception range significantly. The use of relays/repeaters can also be used to increase transmission ranges. Also transmitting and receiving antennas should both point in the same direction (typically up) so they have the same polarization.
QTI Page 5 of 13 Revision: A Form #: 30Z0250 Effective Date: 16 December 2009 Section 3: Serial Interface The MCDT defaults to a low-power shut down mode. Upon receiving an RF message, the MCDT will send the message via the serial port and then return to shut-down immediately. The user may initiate serial communication by sending the MCDT two ASCII characters. After 1 minute of inactivity on the serial port, the MCDT returns to low-power shut down mode. If the user disables the PUSH setting and the MCDT has a new message on hold in the buffer, the shut-down mode will be prevented because this condition pulls the Wakeup [I/O] line low. The MCDT communicates over RS-485. Send a command followed by a carriage return (<CR>). Settings are retained only until power is turned off unless the SAV command is used to store them to the unit’s flash memory. When sending commands and queries, a two-digit hexadecimal checksum (cs) can be used to check data integrity. This is done by preceding the command with “#” and following the command with the checksum value and a carriage return. If a checksum is not desired, simply do not include the # or checksum (cs) value. SETTINGS 38400 baud, fixed No parity 8 bit 1 stop bit No flow control Checksum: To use checksum begin the command with “#” and end the command with the calculated checksum (cs) value followed by the carriage return <CR>. A command with an invalid checksum is ignored and no reply is sent. The checksum is a 2 digit hexadecimal calculated as the 2’s compliment of the sum of the command string. Using the checksum also allows and requires using the serial ID. The universal ID is X, so all units will acknowledge these commands. The unit will respond with its specific ID Example: Sample syntax: Action With Checksum Without Checksum Get channels: #XCHN04<CR> CHN<CR> Returns: #AChnR 2 ChnX 456B0<CR> CHNR 2 CHNX 456<CR> Set channels to 2: #XCHN 2B2<CR> CHN 2<CR> Returns: #ACHNR 2 CHNX 21D<CR> CHNR 2 CHNX 2<CR> Note: “A” is just a sample serial ID, and may be different. Example checksum calculator char CRC2sComp( char *buffr, int end) {//creates 2's complement int c; int calcSum = 0; for( c = 0; c <= end; c ++ ) calcSum += buffr[c]; calcSum ^= 0xFF; //1's complement calcSum += 1; //now 2's complement return (char)(calcSum); }
QTI Page 6 of 13 Revision: A Form #: 30Z0250 Effective Date: 16 December 2009 Message Serial Format Decoded message is sent via RS-485: RXM XX YYY ZZ<CR>, where XX = Message Type, YYY = ID code, and ZZ = status code; all values are hexadecimal. MESSAGE TYPE (XX) The message type consists of two (2) hexadecimal characters. The first character shows the parity; the most significant bit will be set if the parity is bad. The second character identifies the type. Examples of parity: Good parity 0X (0000xxxx in binary) Bad parity 8X (1000xxxx in binary) List of types: MIDS X7 EMIDS/TRSS XD (EMIDS format if TRSS mode OFF (default) / TRSS format if TRSS ON) REMBASS X6 NOTE: Because EMIDS and TRSS have the same message type, the message format is distinguished based on whether TRSS mode is enabled (TRSS format) or disabled (EMIDS format). The MCDT can receive MIDS and REMBASS messages at any time without setting the unit to a particular mode. In addition, the unit can receive either EMIDS or TRSS messages, but the user must specify which for the MCDT to expect since these two have the same message type. ID CODE (YYY) The unit ID code consists of three (3) hexadecimal characters, but only EMIDS messages use all three. MIDS, TRSS and REMBASS are limited to ID codes 000-03F (63). EMIDS uses 000-3E7 (999).
QTI Page 7 of 13 Revision: A Form #: 30Z0250 Effective Date: 16 December 2009 STATUS CODE (ZZ) Status Codes depend upon the message format. MIDS has no status code, and these characters should always be 00. EMIDS status codes are listed in the following table: STATUS CODE ALARM TAMP/TEST LOBATT R>L L>R MEANING 00 0 0 0 0 0 RESERVED 01 0 0 0 0 1 RESERVED 02 0 0 0 1 0 RESERVED 03 0 0 0 1 1 FAULT 04 0 0 1 0 0 RESERVED 05 0 0 1 0 1 RESERVED 06 0 0 1 1 0 RESERVED 07 0 0 1 1 1 FAULT, LOBATT 08 0 1 0 0 0 TEST 09 0 1 0 0 1 RESERVED 0A 0 1 0 1 0 RESERVED 0B 0 1 0 1 1 TEST, FAULT 0C 0 1 1 0 0 TEST, LOBATT 0D 0 1 1 0 1 RESERVED 0E 0 1 1 1 0 RESERVED 0F 0 1 1 1 1 TEST, FAULT, LOBATT 10 1 0 0 0 0 ALARM 11 1 0 0 0 1 ALARM, L>R 12 1 0 0 1 0 ALARM, R>L 13 1 0 0 1 1 ALARM, FAULT 14 1 0 1 0 0 ALARM, LOBATT 15 1 0 1 0 1 ALARM, L>R, LOBATT 16 1 0 1 1 0 ALARM, R>L, LOBATT 17 1 0 1 1 1 ALARM, FAULT, LOBATT 18 1 1 0 0 0 TAMP 19 1 1 0 0 1 RESERVED 1A 1 1 0 1 0 RESERVED 1B 1 1 0 1 1 TAMP, FAULT 1C 1 1 1 0 0 TAMP, LOBATT 1D 1 1 1 0 1 RESERVED 1E 1 1 1 1 0 RESERVED 1F 1 1 1 1 1 TAMP, FAULT, LOBATT Status Code Table
