4.4 Step 4—Measure & Install Primary Power
The primary power at the transceiver’s power connector must be within
10.5–30 Vdc and be capable of furnishing up to 500 mA. The optimum
voltage is 12 Vdc. Be sure to observe proper polarity as shown in
Figure 10.

NOTE: The radio is designed for use only in negative ground systems.
The power supply used with the transceiver should be equipped with
overload protection (NEC Class 2 rating), to protect against a short cir-
cuit between its output terminals and the transceiver power connector.
4.5 Step 5—Review the Radio’s Configuration
There are two essential settings for iNet 900 transceivers that should be
known before placing the radio into service. They are:
Radio Operating Mode—Access Point or Station Adaptor
Network Name—Unique name of the radio network used to
generate the hopping pattern.
NOTE: Transceivers are normally shipped from the factory
pre-configured as remotes.
