Appendix C – Interface Connections
C-1 Introduction
This appendix provides the pin number assignment and wiring information for the connectors on
the EX-5r. All connectors are shown as viewed from the radio front panel.
C-2 T1/E1
Connections
There are two dual-T1/E1 connections. Channels 1 and 2 are on one connector, while channels 3
and 4 are on the other. Channel 1 and 2 are closest to the Power/Ethernet connector near the
corner of the unit.

C-3 Ethernet/Power
Connection
The Ethernet/Power connection of the EX-5r implements Auto-MDIX for the Ethernet function,
and therefore either ‘straight’ or ‘crossover’ Ethernet cables may be used at the data end of the
injector, independent of the wiring of the connected device. The connector on the radio unit
carries DC power on the unused pins. The connector on the injector (the non-DC side of the
injector) is wired as a standard Ethernet connection and implements the Auto-MDIX feature.

C-4 Sync
Connection
The Sync connector is normally connected to a (custom) GPS antenna system.
