pulsAR radio Operator's Manual
Inspect the grounding connections on a regular basis as well as after a lightning strike. Look for
cables that may have been damaged or connections that may have loosen up or oxidize over time.
Replace any damaged cables or connectors and tighten any loose connections.
3.2.3 Power/Ethernet cable
Connect the outdoor cylindrical connector of the CAT5e cable to port D of the radio. The other end
of this cable (with an RJ45 connector) plugs into the indoor Power Inserter Unit.
You can optionally install the Ethernet/Power Surge Suppressor module (SUP-0202) at the point
where the CAT5e cable enters the building. This protects your indoor equipment against surges
induced by nearby lightning on the outdoor CAT5 cable. The surge suppressor has two RJ45
connectors and a ground wire, which you must connect to an earth ground.
If you use a DC source to power the radio, make sure you do not exceed the CAT5e cable length
specified in the table below. At port D the radio requires a minimum of 9.5 VDC (and a maximum of
58 VDC). With the DC voltages shown at the power inserter, the maximum cable length results in an
input voltage at the radio of 9.5 VDC. The radio includes a voltage monitor which you can read with
the
>show command. This can be useful to determine the status of your battery for a battery-powered
installation.

3.2.4 Antenna Installation
NOTICE
The antennas for the pulsAR radios must be professionally installed on permanent structures for
outdoor operations. The installer is responsible for ensuring that the limits imposed by the
applicable regulatory agency (FCC, IC, or CE) with regard to Maximum Effective Isotropic
Radiated Power (EIRP) and Maximum Permissible Exposure (MPE) are not violated. These limits
are described in the following sections.
The pulsAR radio is typically attached to a pole (with the clamp provided) with the antenna
connectors facing up. For optimum performance the radio must be mounted in close proximity to the
antenna with a cable run typically under 2 meters (6 feet). Afar carries several antennas for operation
at either 900 MHz or 2.4 GHz as shown below:
