Introduction
1.1 Scope of Manual
This manual provides Installation and Operating information on the model 7RSP1Radio
Synthesizer Panel which is a component subassembly of the Model RCU-5500 Radio
Communication Unit. The RCU-5500 operates as part of a Load Management Control System
under the control of QUICS IV Supervisory Control and Data Acquisition (SCADA) System
manufactured by QEI, 45 Fadem Road, Springfield, New Jersey 07081.

Description
The 7RSP1 Radio Synthesizer Panel is constructed on a large, printed circuit board measuring
10.5 inches by 9.5 inches. The panel is designed to be mounted inside of various cabinets.
1.3 Purpose
The 7RSP1 Radio Synthesizer Panel is controlled by an external Central Processing Panel which
has received downloaded information from a QEI Master Station. The 7RSP1 Radio Synthesizer
Panel performs a number of functions; it sets a transmission protocol keys the radio transmitter and
modulates the transmitter with data it received from the Central Processing Panel. The 7RSP1
Radio Synthesizer Panel contains a tone generator and performs control functions as well. When
the Request to Send (RTS) signal from the ASCII/external modem port on the Central Processing
Panel is set, data is transmitted to the 7RSP1 Radio Synthesizer Panel. The data is processed and
converted to the protocol used by the radio receiver. Once the radio has been keyed, the data is
then sent to the radio transmitter in the form of Frequency Shift Keying (FSK). An
acknowledgement signal ACK is sent by the 7RSP1 Radio Synthesizer Panel back to the Central
Processing Panel upon receipt of control information. This resets the Central Processing Panel so
that further information can be sent. Outputs on the 7RSP1 Radio Synthesizer Panel can be set for
different impedances and output levels.
