Connections
Connectors for the NET-PATH (labeled Host 1 through Host n) are configured as Data
Terminal Equipment (DTE) and use RJ45 connectors.
Connect the cables from the NET-PATH host ports to the proper connectors on the
host device.
If your host system does not provide the DSR signal, you must loopback the DSR and
RTS signals on the end of the cable connected to the host and ensure the signal passes
through to the cable to the remote agent. Doing so allows the remote agent to detect
connector present from the host; however, it will not detect when the cable is
unplugged. See Figure 2-5 for loopback configuration.
