Optional DC Power Injector
The ExtendAir (TDD) radios use a power injector (sold separately) to send DC power to the radio over
the CAT5 cable, and including the Ethernet connections. Figure 8 shows the power injector
connectors.
Figure 8 Power injector connectors
• Connect the network Ethernet connection to the DATA connection of the power injector.
• Connect the cable for the radio to the DATA+POWER connection of the power injector.
• Ground the power injector using the grounding receptacle. The injector can also be mount wall
using the bottom panel brackets.
CAT5 Lightning/Surge Protection
To provide for human safety and for the safety of connected network equipment, it is highly
recommended to place a weatherproof lightning suppression device at the egress point where the
CAT5 cable(s) enter the building, shelter, or cabinet.
To protect the radio equipment, install a weatherproof lightning suppression device near the radio for
all connected CAT5 cables.
For the Power/Ethernet cable, specific voltage requirements must be met. The following devices are
the only devices currently recommended:
• Transtector ALPU-EXLT
• Transtector ALPU-90v
• Transtector ALPU-ALVR
Generally, use a short CAT5 cable for the short connection between the radio and the first arrestor. Use
bulk outdoor-rated CAT5 cable for the longer run between arrestors, and indoor- or outdoor-rated
cable with a standard CAT5 termination for the connection from the egress arrestor and power injector.
If the radio arrestor is deleted from the design, Exalt resellers can supply a longer cable with the proper
weatherproof connector for the connection from the radio to the egress arrestor.
Apply this same method for the TDM connections. There are no special requirements for lightning
arrestors. Vendors, such as Transtector and Polyphaser, offer single and multiple TDM weatherproof
arrestors. Note that each connector on the radio can carry up to 2 TDM (Time Division Multiplexing)
connections.
