MSAT-G2 Mobile Satellite Radio – FAQ

A. Installation

Ignition Sense Wiring

•
The ignition sense line (orange wire) can be used to switch the radio on and off. It is
typically connected to the ignition switch on a vehicle. If a switched source is not used
then it must be connected to +12 VDC.
•
If the radio is turned on without +12 VDC applied to the ignition sense line the radio will
automatically power down after approximately 30 seconds.
•
If the radio is turned off using the handset power key then the ignition sense line will be
ignored. The radio must then be turned on using the power key.

Current Consumption

•
The maximum current draw for the radio is 3 Amps. This can occur when the unit is
transmitting, the antenna is rotating (vehicle moving), transceiver heaters are on, etc.
•
The radio requires input voltage between 11.5 and 15.6 VDC. If the voltage drops below
that range the radio my automatically power off. If this happens ensure that the power
source is providing adequate voltage during the extra current draw that occurs when the
radio is transmitting.
•
The following are typical current values when the antenna is not rotating (radio is
stationary) and the transceiver heaters are off:
Radio Idle or Receiving Call:
o
Radio Transmitting:
o

Handset Cable Extension

•
The handset cable can be extended with standard CAT-5E cable and RJ-45 couplers up
to 25 feet. Longer cables may be used but the specific installation should be tested to
ensure that audio quality is not affected. If a long cable extension is required or if the
extension is in an electrically noisy environment then the Link Communications Handset
Extension Adapter should be used.

Lightning Arrestor/Protector

Applicable electrical code(s) may require that lightning arrestors/protectors capable of
supporting L-band transmissions be installed on all cabling between the fixed-site
antenna and the structure in which the equipment is housed. It is the professional
installer's responsibility to determine all such requirements with the customer. The
equipment installation must comply with all applicable standards.
