1. Change the default node address on at least one of the SLC's. I don't remember exactly, but I believe the default node address is 0. Change one SLC to node 1, and the other to Node 2. This is done using channel configuration, then clicking on the Channel-1 system tab. You will also have to ensure that each SLC is set for the same baud rate.
2. Connect the two SLC's using Belden "Blue Hose", you will need a terminating resistor at each end of the blue hose, the baud rate selected in step one will determine the value of the resistor, for example if I remember correctly, 57.6 is 150 ohms.
3. Once the two systems are physically connected. You will have to use the MSG instrcution to pass data between the two systems.
I would highly recommend you go to the AB website and download a couple of manuals on the SLC instruction set, and DH+.
