See pages 16 and 81 for details on the maximum transmission distance.
1. Always turn OFF power to the Repeater Unit before setting the baud rate.
2. Set the same baud rate for all nodes on the network.
3. The factory default setting is 2 Mbps.
Turn ON the terminating resistance at the Unit located at each end of the net-
work. The terminating resistance switch is located on the front of the Unit. The
terminating resistance is required at both ends of a network, or both ends of a
segment, to absorb unnecessary signals and reduce noise.
When a Repeater Unit is located at either end of the Network, turn ON the ter-
minating resistance switch of the Repeater Unit.
