Figure 57 RSL & Sync In/Sync Out connector
Two Radio Internal Sync Out/In
If using the Internal Sync Out/In function between two radios only, connect Pin 8 from the Sync Out
radio to Pin 6 of the Sync In radio and use a straight connection for Pin 2. Connect no other pins. To
ease the need to keep track of which end of the cable is for In and Out, consider cross-connecting Pins
6 and 8, with a straight connection for Pin 2. Connect no other pins.
Sync Distribution Accessory
If using a sync distribution accessory (sold separately), connect CAT5e cabling straight from the radio
Sync connector(s) to the accessory.
Power/Ethernet Connector
This connector is the primary connector on the radio, and must be connected to provide power to the
radio, and primary Ethernet communications for traffic and Ethernet. Figure 58 illustrates the pin
orientation and functionality for this connector.
The Ethernet cable between the PoE injector (or integrated AC/injector) must be wired as a straight
connection. The wiring follows typical wiring for Power-over-Ethernet (PoE), however the power
consumption requirement for the ExtendAir (TDD) Series radio does not allow for ‘standard’ (802.3af)
PoE, and only the Exalt power injector shall be used. In addition, the Exalt power injector provides
critical reset and alarm capability that would not be available from a generic PoE injector, even if the
power consumption requirement is met.
