4.1 GENERAL

4.1.1 PROGRAMMING SETUP

The following items are required to program this transceiver. The part numbers of the programming cable and software are shown in Table 1-1.A printer is also recommended for making a hard copy record of the information programmed into the transceiver. The programming setup is shown above.

•IBM® PC AT or PS/2 compatible computer with one available serial port

•MS-DOS® version 5.02 or higher or equivalent

•E.F. Johnson programming cable (includes required level converter circuit) and adapter cable

4.1.2 PROGRAMMING CABLES

Programming Cable, Part No. 585-7500-031, and Adapter Cable, Part No. 585-7600-031, are required to

connect the computer to the transceiver. The program- ming cable has a female DB9 connector which plugs into the serial port of the computer. In this connector is

alevel converter circuit which converts the RS-232 levels of the computer to the logic levels required by the transceiver. The other end of the cable plugs into the adapter cable which adapts the miniature phone plug to the modular-style microphone connector on the transceiver. Turn transceiver power on after these cables are connected.

4.1.3 PROGRAMMING SOFTWARE

The programming software is distributed on a 3-1/2” 1.44 M diskette. This diskette includes the main executable program RP7600.EXE and several ancil- lary files it requires to run. These files total approxi- mately 430k in size. Also included on this disk is the ADJUST program used to tune the transceiver. This program and other files it requires to run total about 180k in size and are located in a separate subdirectory
