4 Channel Relay - Repeated Commands - Requires Wait


We have a 4 channel relay, we have purchased several and you can look up our account. I’m pretty sure it’s the only one type that we have ordered.

If I send multiple commands to the relay it refuses to all but the first. However if I work a 25 millisecond wait between each command it runs fine.

I have two wireshark files that I’d like to attach but am not sure how to do that.

  1. Wireshark file where the command fails (without a wait)
  2. Wireshark file where the command works (with a waits between each command)

Let me know how to send this



It is always recommended to read the response from the relay controller before sending new commands to it. This makes sure that the processor on the relay controller is ready to receive new commands.
