pulsAR radio Operator's Manual
Alternatively the radio may also be powered over the spare cat5 line pairs (pins 4-5 and 7-8). On
these lines the radio accepts a DC voltage over a very wide range (10 VDC to 58 VDC), allowing it to
easily be powered by a 12 V battery. This method is not in compliance with the IEEE 802.3af mode
B, which restricts the voltage range to 48 VDC.
Afar provides two Power Inserter devices (figure 1.2) that use this second method. One is for
operation from an AC source (110-240 VAC), and the other for operation from a DC source (10 to 58
VDC).
The AC Power Inserter Unit includes a power supply for connection to an AC outlet (110-240 VAC).
The DC Power Inserter Unit comes with a 10 ft pigtail for connection to your DC supply voltage.
Both inserters have two RJ45 connectors and an LED. The two RJ-45 connectors are labeled “To
LAN” and “To Radio”.

Connector/LED Type Function
To LAN RJ-45 10/100 Base-T to be connected to the Local Area Network. You
can connect this directly to the LAN port of a computer or to an
Ethernet hub. The radio auto-detects and provides the cross-over
function when required. See table 1.5 for pin assignments.
To Radio RJ-45 Carries the DC power and Ethernet signals to the radio. See table
1.6 for pin assignments.
LED
(AC Power Inserter)
Amber/
Green
Amber : Indicates that the power inserter unit has power from the
wall supply but no power is being drawn by the radio.
Green : Indicates that the radio is drawing power.
LED
(DC Power Inserter)
Green Indicates that there is DC power in the pigtail input
WARNING
The Power Inserter connectors labeled “To radio” includes DC voltage in two of the pins. It must
not be connected to a LAN as this voltage may damage some LAN cards.
