We just purchased 2 new ZADSR32xPROR relays cards to use in a RS232 legacy system. These are very different then the original ones we have. I was able to set the EC3 addresses with the NCDBaseStation like before but they did not response to the RS232 commands. We use 2 cards connected together. (Device 1 & 2). I do see the communication lights blinking when the commands are sent. I could operate each card independently with the Base Station originally but they didn’t work with my test software. Now I can’t do that anymore, they do not respond to any commands.
I can connect with the NCDBaseStation now but I can not control any of the relays. Could I have changed a setting that would cause this? Is there a way to restore to the factory defaults assuming I changed something incorrectly? We assumed they were drop in replacements.
