Repeater Units can be used to construct flexible networks such as those
shown below.
31 nodes max.
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
is ambient temperature, and λ is the peak wave-
