Mounting the
NET-PATHm
The NET-PATHm includes rubber feet to prevent travel. We recommend that you do
not stack additional equipment on top of the NET-PATHm.
Connections
Connect the host port lines, telephone line, physical sensors, network connections,
and power supply connections to the appropriate sockets on the NET-PATHm
connection panel.

Connections
Connectors for the NET-PATHm (labeled Host 1 and Host 2) are configured as Data
Terminal Equipment (DTE) and use RJ45 connectors. Connect the cables from the
NET-PATHm 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 2-1 for loopback configuration.
