D 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.

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. RJ-45 Pinouts MDI Pin 1=TX+ Pin 2=TX- Pin 3=RX+ Figure 2. RJ-45 Pinouts Pin 6=RX- 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) 1 2 3 4 5 6 87 Model: MIL-120A Legal Regulatory Approvals • FCC Class A • UL 1950 • CSA 22 No. 950 • EN60950 • CE – EN55022 Class B – EN50082-1 Canadian EMI Notice This Class A digital apparatus meets all the requirements of the Canadian Interference-Causing Equipment Regulations.
