If no expected response is specified, the multiplexer returns

$PSMDWC,message

where message is the response from the module.

The module-specific commands are not listed here because they fall outside the scope of this

specification.

Note that the multiplexer responds with a $PSMDWC sentence when it is in command mode. In

normal mode, a $PSMDWI response is given. A PSMDWI sentence without any parameters exits

command mode. When this sentence is issued in normal mode, a $PSMDWI,No response is

returned.

Terminal Mode

Terminal Mode creates a direct connection between the wired and the wireless interface for testing

and debugging purposes. All other inputs and outputs of the multiplexer are inactive.

A $PSMDWI,T sentence enables Terminal Mode with the wireless module in Data mode. The

blinking red LED indicates Terminal Mode.

At this point, a direct connection exists and no NMEA commands are recognised by the multiplexer.

The connection is completely transparent and any (NMEA) data is passed in both ways. Three

control codes are implemented to control Terminal Mode:

Ctrl-q: Exit Terminal Mode. The wireless module will be set to Data mode and the multiplexer

returns to normal operation. The red LED is off.

Ctrl-c: Switch the wireless module to command mode, to control the configuration of the module

through the wired interface.

Ctrl-d: Switch the wireless module to data mode.

Cycling the power of the multiplexer also exits Terminal Mode.
