Expedition Navigation Software / H3000 HLink Data Dropout and Display Hang

**Posted by kcumming** 6/16/2025 7:00 am

I'm running HLink via RS232 to a B&G H3000 Hercules Motion Processor. I'm sending Alternating channels to the mast displays. It seems that only 2 of the 3 displays I'm trying to send are showing the proper data and we''re getting frequent data dropout on the H3000. Additionally the displays, including the GFD's lock up and require a system reset to work. Has anyone experienced this type of issue?

Try not sending tags with them.

Old Hercules systems were notorious for freezing with the display tags. Mostly it was ok if the frequency was longer than 3s, but ...

Yes.

Running H2000 with one H3000 GFD. Similar problems when using alternating.

I run many EXP channels with "refresh tags" off - just send them once when you start up the system if needed. I have very few problems if I stay away from alternating channels.

If you run into any problems with display lighting while running Expedition, please get in touch.
