Below are the front and back views of the module. The power supplies on both sides are connected together, so only one side needs to be connected. There are two separate channels on each side, both of which can be used. The arrows indicate the direction of signal flow; inward arrows indicate input, and outward arrows indicate output. The side near the RS232 character terminal is at RS232 level, and the side near the TTL character terminal is at TTL level
