Revision G USER’S GUIDE

Code Upgrading

The DR-915L and DR-915LT have been designed for easy field upgrades. Using the RS-

232 Serial Adapter board, a DR915 Programming cable, a standard Serial Configuration

cable and a current version of the DR-915L/LT Configuration program running on the

user’s PC, the radio can be re-flashed with new operating code. Special customer code

can also be loaded in this manner.

With the radio mounted on an RS232 Serial Adapter board, connect a program upgrade

cable from the programming connector, J4, on the Adapter board to the parallel port on

the PC. Connect a standard DB9 male-to-female serial cable from the Adapter board’s

DB9, J2, and to the serial port on the PC. Power the Adapter board using the supplied

12-volt wall module connected to the Adapter board’s power jack, P8.

Using the DR-915L/LT Configuration program, click on the Flash tab. Select the

software version from the Software Version drop-down box and then press the Program

Flash button. The Configuration program will then read the setup information from the

radio, upgrade the radio code and reload the original configuration.
