RESET – Reset the multiplexer

This sentence resets the multiplexer and starts the bootloader. When a ‘1’ is given as parameter,

the factory settings of the multiplexer are restored.

Format: $PSMDRESET,x[*hh]<CR><LF>

x: Optional parameter to indicate an action while resetting

1: restore the multiplexer to its factory settings

After a reset, the multiplexer outputs a LDR sentence and a VER sentence on the host interface.

SP – Speed

This sentence sets the baud rate of the NMEA inputs and outputs.

Format: $PSMDSP,a,b,c,d,e,f[*hh]<CR><LF>

The following fields are defined for setting the various inputs and outputs:

a: NMEA In 1

b: NMEA In 2

c: NMEA In 3

d: NMEA In 4/Out 1

e: NMEA Out 2

f: RS-232 host port (ignored on multiplexers without RS-232 host port)

Valid field values are:

0 = 4800 Baud

1 = 9600 Baud

2 = 19200 Baud

3 = 38400 Baud

4 = 57600 Baud

5 = 115200 Baud (field e and f only)

Field ‘d’ is ignored when SeaTalk translation is enabled with the CF sentence.

SPQ – Request Speed

Request the baud rate settings of the NMEA inputs and outputs.

Format: $PSMDSPQ[*hh]<CR><LF>

The multiplexer responds with an SP sentence.

TAG Block

When the Channel Numbers option is set to ‘2’ (field ‘n’ of the CF sentence), the multiplexer adds a

TAG block to every NMEA sentence that is output on the host interface. This TAG block has one

source parameter, indicating the input that sentence was received on. It has the following format:

\s:mchx*hh\

where ‘x’ is a digit from 1 to 4, representing the input number. A heading sentence received on

input 1 will be sent to the host as

\s:mch1*1E\$HEHDT,23.5*37<CR><LF>

1 2 ... 33 34 35 36 37 38 39 40 41 42 43 44
