Introduction
This document describes the 10 key steps required for configuring the radio and demonstrating
remote diagnostics on a pair of J Series radios operating in Point to Point ( PTP ) mode. After
successful diagnostics polling is achieved, subsequent testing can then be done on user
equipment such as RTUs or PLCs.

RF Connection
It is recommended that whip antennas are not used to simulate a long distance
RF link. RF attenuators are far superior to antennas for short-distance bench testing as the
attenuation of the RF signals between both radios is consistent and is not subject to external
interference. Alternatively 90dB of separation can be achieved with 50 ohm dummy loads or
small whip antennas (minimum separation 1m or 3ft).
(1) If the TX power of each radio is set to 20dBm (100mW) then low power, low cost
attenuators can be used.
(2) Small whip antennas can also be used, but the signal into the receiving radio should be no
greater than -30dBm (set Tx power on all radios to 20dBm).
DC Power Connection
Ensure each radio is wired using the correct polarity and that power supply
is regulated and has adequate current delivering capacity.
