FLQ – Request Filter List

This sentence requests the filter list from the multiplexer. The multiplexer responds by sending FL

sentences, one for each list entry. An empty FL sentence marks the end of the list.

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

Example response:

$PSMDFL,GPRMC,100110,0,1111*4A<CR><LF>

$PSMDFL,GPGGA,100010,0,1111*56<CR><LF>

$PSMDFL,--VWT,010000,5,0001*50<CR><LF>

$PSMDFL,GPGSV,000010,0,0010*55<CR><LF>

$PSMDFL,*2C<CR><LF>

The sentences may not be dumped as one contiguous block. In case of much NMEA data, they may

be interspersed with other NMEA sentences.

ID – Talker ID

This sentence sets a Talker ID translation for a specific input. If a Talker ID is set, the original

Talker ID of the sentences received on that input is replaced by the specified one, before sending

the sentence to the host.

Format: $PSMDID,aa,bb,cc,dd,ee[*hh]<CR><LF>

aa: Talker ID for channel 1

bb: Talker ID for channel 2

cc: Talker ID for channel 3

dd: Talker ID for channel 4

ee: Talker ID for internally generated sentences

hh: optional checksum

An empty field clears the ID and disables the translation for that specific channel. Sending PSMDID

without any fields clears all translations.

IDQ – Request Talker ID’s

Requests the Talker ID translation settings. The multiplexer responds with an ID sentence.

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

LDR – Loader message

This sentence is output by the bootloader on the host interface. It contains the loader version and

multiplexer ID. The loader will wait for a special key during 0.2s after sending this sentence. When

no key is received, the multiplexer application code is started. If no application code is found, the

loader will continue sending this sentence.

Format: $PSMDLDR,xx,v.v,zzz

xx: Hardware ID of the multiplexer (a hexadecimal number)

v.v: Bootloader version number

zzz: Hardware name of the multiplexer

The following hardware ID’s and names are defined:

01: MPX-S (board with RS-232 interface)

02: MPX-U (board with USB interface)

03: MPX-E (board with Ethernet interface)

04: MPX-W (board with USB and WiFi interface)

When bit 7 of the hardware ID is set, e.g. 81, the board has a Bluetooth module installed.

Example: $PSMDLDR,82,1.2,MPX-U

This multiplexer has a MPX-U board with a USB interface and a Bluetooth module installed and

the bootloader is version 1.2.

OV – Overflow

In case of a queue overflow (blinking red LED on the multiplexer), an overflow sentence is output

on the host interface, to indicate on which input queue the overflow occurred:

Format: $PSMDOV,x*hh<CR><LF>

x: Binary field. The first four bits indicate on which input queue the overflow occurred.
