The relay rack can be connected to header J3 or J2 on the 826 board.
You must supply 5 VDC power to the relay rack. This can be done in either of the following ways:
- Connect an external 5 VDC power source to the relay rack's +5V and GND terminals.
- Attach a wire on the bottom of the relay rack (via solder) from the +5V terminal to J1 pin 49.
