Digi MIL-120A manual Installation, Link Test, Disabling Link

Install Guide

Installation

Do the following to install the MIL-120A:

1.Attach a UTP cable from the network to the MIL-120A's RJ-45 port

2.Attach a T-type BNC connector from the network cabling to the BNC connector

3.Connect the power adapter's cord from the power source to the unit

Note: Use shielded twisted pair (CAT 5) cabling for CISPR 22 B installation.

Link Test

The MIL-120A provides a Link test function, which is a 10BASE-T standard. The MIL-120A ships with the Link function test “enabled”—only pin one jumpered with a jumper block. This allows the LEDs to illuminate when there are links.

Disabling Link

To disable the Link test:

1.Use a Phillips-head screwdriver to remove the four Phillips-type screws located on the sides of the unit

2.Remove the BNC nut and its washer

3.Slide the housing off, over the BNC connector

4.Locate the two-pin Link jumper (Figure 1)

5.Place the jumper block onto both pins

6.Reassemble the unit (reverse steps 1 through 3)

Note: The MIL-120A operates in a “StarLAN-10” environment when Link is disabled. Only the Power and Link LEDs Illuminate.
