GRT is closed till the new year; does anyone know what is the highest baud rate the low speed serial ports on a WS EFIS can handle. Thanks Barry

Barry,

For my GRT Sport HS EFIS, the max baud rate on the low-speed serial ports was 57,600 (used for the inter-display link).

The fastest rate I see in the manual for WS serial ports 3-6 is 9600 baud. I don't however see a max rate mentioned.

It may depend on whether the WS is a Horizon or Sport.
The Horizon has one or two that go to 115k baud. The rest are limited to 57k baud. I do not know the Sport capabilities.

Thanks ya'll, I have the WS Horizon

I checked the spreadsheet I have for my RS-232 plan.

Ports 1 and 2 on the WS H1 are high speed.

However, if you have a plug-in box like ARINC, it uses port 1 and gives you a replacement port but it is a low speed.

Not sure if the GPS plug in does the same. I don't have one.
