The SINCGARS SIP system inserts two new LRUs into the SINCGARS equipment suite. These are the
Receiver-Transmitter, Radio RT-1 523C/D and the AmplifierAdapter,Vehicular, AM-7239C/D. The radio is
common with manpack and vehicular configurations for RF operations. It supports synchronous and
asynchronous data interfaces, provides DCE services for the MIL-STD-1 88-220A packet interface, and
interfaces with the Precision Lightweight GPS Receiver (PLGR). The Vehicular Amplifier-Adapter (VAA) serves
as a vehicular mount for two manpack radios, provides synchronous and asynchronous data interfaces,
provides the DTE and router portion for MIL-STD-1 88-220A packet switched network services, and may be
used as a communications device for data transmissions over wire with a Mobile Subscriber Equipment (MSE)
Small Extension Node (SEN) and with the Enhanced PositionLocation Reporting System (EPLRS).
