Model: MIL-170TRM 3
MDI-X/MDI Switch
The MDI-X/MDI switch allows for quick configuration of the 10BASE-T port.
Cables used when the switch is in the MDI-X position (the “left” position):
• For a hub/repeater, use a swap cable (pins are connected 1 to 3, 2 to 6, 3 to 1,
and 6 to 2)
• For a workstation/PC, use a straight-through cable (pins are connected 1 to 1,
2 to 2, 3 to 3, and 6 to 6)

Link Sentry Configuration
The Link Sentry feature on the MIL-170TRM is configured through a 4-position
DIP switch (refer to Figure 1). Default setting for the DIP switches: All switches
are in the “up” position.
Link Sentry allows users to add new management tools to the network. When
enabled, it monitors the selected receiver port and, if the Link test signal is not
seen, the unit will stop sending a signal through the selected transmit port.
