4.3 PROGRAMMING
Each transmitter and receiver can be programmed for
any operating frequency, address code and specific
operating parameters required by the particular system.
Each system is fully programmed and tested before
shipment from the factory and should require
reprogramming only in the case of spares.
Programming Hardware Requirements
The RAC17, a computer based programming system, is
available that consists of an RS-232 interface box and a
computer program for PC compatible computers. This
system allows storage of configurations for each system
