Note 1. Repeater Units must be supplied with 24-V DC power.

2.Wire-to-Optical Repeater Units (CS1W-RPT02 and CS1W-RPT03) are used to convert a section of a wired network to optical fiber. Two Units are always used as a single set.

Wire-to-Optical Repeater Units cannot be connected to Optical Ring/Opti- cal Controller Link Units or Support Boards. If these types of Controller Link Units or Support Boards are connected by mistake, communications errors will occur throughout the network.

3.Repeater Units have a baud rate switch and a terminating resistance switch. The same baud rate must be set for all nodes on the network.

In addition, the terminating resistance switch of Units (Controller Link
