QK-A032 NMEA183 output————Solved

[Anonymous]

Hello,

 

I just bought a QK-A032 for my Raymarine network in order to send the position to my VHF (Ray49E). The A032 is now connected to the network. Unfortunately I have the following problem:

– using the A032 usb output, I can see the GLL sentences (egg. [09:29:09 (Serial:COM4) $GPGLL,4729.9194,N,00222.6328,W,,A,A*55<0x0D><0x0A>] between brackets)

– using the nmea183 output, I cannot see these GLL sentences (although they are collected by the A032), it seems that this interface does not work, is there something special to do ? I have set the parameters for the nmea183 interface (egg. speed). I have connected this way:

–> A032 white (OUT+) to IN+ AIS, 9600 baud
–> A032 blue (OUT-) to IN- AIS, 9600 baud

My AIS has been used to control the sentences coming in.

Kind regards,

Jean-Marc

Hi,

Please ensure baud rate is set to the same speed for both the A032’s output and the VHF radio’s input (4800bps or 38400bps, if high speed data transfer is required, e.g., for AIS data).

If the connection does not work, swap the NMEA + and NMEA – data wires:

A032 NMEA 0183 OUT+   ->   VHF radio’s NMEA IN-

A032 NMEA 0183 OUT-    ->   VHF radio’s NMEA IN+

Please switch off your devices and disconnect them from their power supply before connecting/disconnecting data wires.

Hope this helps.

Hi,

Thank you for the hint, I’ll try next time I’ll be on board. Let me know: 9600bps is not acceptable if on both sides ? Is it better to limit either to 4800bps or 38400pbs ?

Best regards,

Hi, I would suggest you go with 38.4kbps to avoid overflow issue. Then you probably could try 9.6k if high speed data transfer is not required.

Hello,

 

Thank you for your recommendation, it is ok when + is connected to – and vice versa, i.e.:

A032 NMEA 0183 OUT+   ->   VHF radio’s NMEA IN-

A032 NMEA 0183 OUT-    ->   VHF radio’s NMEA IN+

Note that A032 NMEA 0183 OUT+ is named “OUT A+” and A032 NMEA 0183 OUT- is named “OUT B-”

Kind regards,

Jean-Marc
