2 years ago Hi - check out the hardware wiring guide here: https://www.cisco.com/c/en/us/td/docs/routers/access/1101/b_IR1101HIG/b_IR1101HIG_chapter_01.html#con_1232292
- IR1101's PIN 5 is the return (or GND on the relay board)
- IR1101's 4 other PINs are GPIO 1-4 that are going to the relay board inputs IN1-IN4.
- For the relay board VCC (5V) I have used the IR1101 USB port which also supply 5V, but you can also use an external 5V source.
Hope this helps Emmanuel
Hiya, do you have a diagram of how you have wired your relay board to the IR1101 that you could share. The last picture doesn't quite show the breadboard.
