Author Topic: Serial coax switch control from HRD  (Read 2954 times)

I bought serial to 8 relay boards to control home brew coax switches.
Each command to the serial board is 8 bytes in hex format. Using RealTerm it works well.
I build one for myself and 3 for others in our club. I use DX Labs and have a solution for automatic band switching the serial coax switch.

The others use HDR, it is here I need some suggestions. So far the solutions seem limited to;
-  TRX Manager for $55 and not being integrated with HDR
-  Using a small eval board (CPLD, Tiva, etc) to extract freq info from CAT and then passing the desired switch selection to the relay board. Unless I write a driver with a user GUI the band break/selected port will be hard coded into the eval board. I do not like either approach.

At the start of the project I thought I found a HRD screen shot showing Hex words in a config window just for this application. I have been through the HDR manual and have searched the web and can not find a HRD solution.

Any ideas?

DDUtil_V3 interfaces nicely with a single USB 8-relay board.  I've used it when I needed a way to cycle power to a remote antenna tuner.
