H3000 XDR Heel and Trim not working

I have a H3000 hydra processor  using a serial interface  directly connect to the processor, all works fine expect for the Heel and trim which I can't get to work. It looks like the sentence send out the wrong checksum.  The sentence is $IIXDR,A,-0.2,D,HEEL,A,-0.1,D,TRIM,A,13.0,D,RUDDER*4E recorded straight out oof the processor.  if run it past a checksum check the checksum should be *66 . I can't change this in the H3000,  is their any way of ignoring the checksum or customizing the checksum field for sentence that our out of bound? 

I would realy like to record Heel and trim for performance purpose and be able to send out target heel bank to the CPU.

That works as expected. Have you told Exp to receive the XDR sentence?

Setting are H3000 Hydra with XDR sentence on, selected Heel, selected rudder in the XDR section of the nmea setting. Any where else where I need to set the XDR setup?

Did you also select Roll/heel and Trim/pitch?

As well as each XDR option on the right, there is a global XDR checkbox on the left of the NMEA page.

Re: H3000 XDR Heel and Trim not working

On the selected NMEA sentence to recieve XDR is on and in the middle section Roll/Heel, Rudder and Trim/Pitch are selected. Data selected in the number boxes is "Heel (Roll)" 
When i had the system connected to a H3000 Hercules Performance using Hlink heel was showing, this is a different boat with a H3000 Hercules so i can't use Hlink but have to use NMEA and I see the sentence coming in just not displaying.

I have enable heel and trim in the H3000_config.txt, not in the H2000_config.txt, could this be related? The input is NMEA not Hlink?

The H3000_config file is just for HLink.

I presume you are using a recent Exp release?

Maybe mail me a screen image of the NMEA settings page and a sample from raw data?
