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 meters 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)
