The Out of Lock signal is set low by two radio module if the synthesiser has not locked
within 70mSec of ,either TXON or RXON being asserted
The SOX input can be used to send serial commands to the module or pass serial data to the
transmitter.
The command character 02H sent to SRX will divert all following serial data to the SOX output.
This output can be connected to the DIN digital input hence only one serial port is needed to
control the radio module status and transmit serial data over the air.
The STX output and the SRX input can be used to interrogate the X7000 Radio Module
via a serial port and set the following parameters.
The SRX port receives serial data from en external source and the STX transmits serial
data from the X7000 radio module Both operate at half duplex, TTL levels, 9600 baud 8
data bits. 1 stop bit, and no parity. A start bit is defined as a transition from 5V to 0V
Serial Protocol
The X7000 Module is interrogated on the SRX pin by the host sending O5H.
The module will send an acknowledge byte from STX of 06H.
The host has 3.6sec to send one Of the following command bytes:
49H
4CH

YNTHESISED
Forces both receive and transmit channels to the
channel set on the DIL switches.
If this character is sent the module will expect two
further bytes of data. The first byte will set the RF
transmission frequency The second byte will set the
RF receive frequency. The channel bytes are shown
in the DIL Switch Table
