MReX Transceiver User Manual v1.92 Firmware

Configuration

Parameters can be changed using any common serial terminal program. A serial terminal program

that also allows saving and loading of configuration files can be downloaded from

wte.co.nz/tools.html

Start-up operation is always at 9600:8-N-1.

All configuration commands always start with the asterisk ‘*’ character.

All messages that do not start with the * character are processed by the protocol decoder.

All messages are terminated by a Carriage Return character, shown in this manual as <CR>

All commands that accept a value, can have that value read back by using the ‘?’ suffix. E.g.

*TX_FREQ?

Returns

*TX_FREQ=460000000 (for example)

There are some commands that support multiple entries (such as the same command but for differ-

ent ranges). In this case the question mark can be followed by the parameter to be interrogated. E.g.

*RX_RANGE?<CR>

Returns (lists all ranges)

*RX_RANGE=1:8,2000000

*RX_RANGE=2:0,0

*RX_RANGE=3:0,0

*RX_RANGE=4:0,0

To find the first range only, usage would be:

*RX_RANGE?1<CR>

Returns

*RX_RANGE=1:8,2000000

Note: It is a good practice to restart the unit after changing configuration. This can be achieved by

removing power to the unit or sending the *REBOOT<CR> command.
