Connect the Cable
This section describes how to connect cables by using the tracer on the cable to
identify and follow the cable throughout your system.
A tracer is one of the two wires on the duplex cable that is one of
the following:
• Printed with the cable legend
• Ribbed
For further information on choosing cables and wiring your system, refer
to the ControlNet Fiber Media Planning and Installation Guide,
publication
.
The instructions explain how to connect the cable between the fiber modules by
making a simple ‘criss-cross’ connection. To do this, you will connect the cables
between modules from the receive (RX) end of one channel to the transmit
(TX) end of the other module, as shown in the following diagram.
Do these steps to connect the cable.
1. Use the tracers on the cable to identify which cable is connected to the
receive (RX) port and which one to the transmit port (TX).
TIP
Channels 1 and 2 on the module are identical. Channel 1 of a
module can be connected to either channel of another module.
