COL/TP: Collisions are occurring on the 10BASE-T network
RCV/TP
Link:
Unit is receiving packets from the 10BASE-T network
There is an active connection to a10BASE-T hub (or another node)
when Link is enabled
Power:
Unit is receiving power
RCV/CX Unit is receiving packets from the 10BASE2 network
COL/CX: Collisions are occurring on the 10BASE2 network
Configuration
Next to the COAX cable connector, there is a DIP switch that control the 50 ohm
termination resistor (Figure 1). These switches support a variety of configurations.
Both switches are shipped in the UP position (default). Other configurations
include:
If the MIL-120A is connected to the end of a multi-node segment without a T-
connector and terminator, enable the 50 ohm resistor by:
•
•
Placing switch 1: UP and
Placing switch 2: DOWN
If the MIL-120A is connected to a single-node “without” a T-type connector and
terminator on a COAX cable of less than one meter’s length:
•
Place both switches (1 and 2) in the DOWN position
Note: For this configuration, you do not need a 50 ohm terminator on the COAX segment of the
MIL-120A's BNC connector.

Follow these guidelines when connecting the 10BASE-T Port:
•
For a Hub or a Repeater, use a straight-through cable (where the pins are
connected 1 to 1, 2 to 2, 3 to 3, and 6 to 6)
•
For a Workstation/ PC port, use a swap cable (where the pins are connected 1
to 3, 2 to 6, 3 to 1, 6 to 2)
