3.3.4 Installing new firmware using the RS-232 serial port
On occasion, it may be necessary to install new firmware using the RS-232 port. This is generally a
less desirable method as the download time is much longer and you can only update the radio that is
directly connected to the PC, i.e., remote updates are not possible.
The serial upgrade uses a PC with a terminal emulator. Any emulator can be used, however, it must
have the facility to download a text file on demand. In the example below, the emulator used is
Windows HyperTerminal.
1. Connect the PulsAR Auxiliary Port (3 pin circular connector) to a terminal, or a PC running a
terminal emulation program. A special adapter cable is supplied by AFAR. Configure the
terminal settings as follows:
Baud rate: 9600
Word length: 8 bits
Parity: none
Stop bits: 1
2. Verify that the new software is available in the PC. The download software for the serial upgrade
must have a “.dwn” extension, e.g., pmp03_25.dwn.
3. To have the shortest download time possible, set the radio to use the highest RS-232 speed
allowable on the PC. In this example, a download speed of 57600 baud will be used. Set the
console speed of the radio to 57600 baud by issuing the command:
