Hey all!

 

I'm having a doozy of a time getting my PC to recognize more than one Sainsmart board at a time. It KNOWS there are two boards, but even the Sainsmart USB Relay Manager software will default to the one board. It detects two boards, and I can choose between the two, but the software will only interact with one. It seems to think both boards are the one board? I dunno... It's so strange.

 

If I only have one plugged in, the relay manager will work with either. Is there something weird going on in the EEPROM? They both have different serial numbers. Does anyone here have experience hooking up multiple Sainsmart relays and can you get the relay software to switch between the two correctly? 

 

Thanks in advance.

Thanks for the reply!

 

I think I have it working, although my encoder board loses connection from time to time. Probably a USB power issue.

 

Thanks again!
