5 / 11 page Radiometrix Ltd TX2M/RX2M Data Sheet page 5 TX2M and RX2M serial interface commands 2400 baud at RS232 level. 8 bit data, no parity, 1 start bit, 1 or 2 stop bits, No flow control. Transmit (pin 3 on DB9) and Signal Ground (pin 5 on DB9) should be connected to PGM and 0V pin. Command Format Description SINGLE nnnnn Set value of N for single channel operation GOCHAN xx Serial select of channel xx (0 to 127) LOADMX xx Set highest permitted (serial selected) channel xx (others default to ch0) LOADaa nnnnn Set value of N for channel aa (channels 0 to 15) LOADTB nnnnn Set value of N for channel 16 (channels 17 to 127 then in sequence) RVALUE rrrr Enter value for R register SETPAR Channel selected by 3 bit parallel input (0 to 7). Disable modem SETSER Channel selected by most recent GOCHAN operation SETMOD Enable internal modem.
