At the main menu, press F3 to go to the codeplug menu. We’ll now “read the codeplug” – this means that we fetch the current settings from the radio. Press F8 to save it, after that, press F10 twice to go back to the main menu. If it’s not, use the arrow up/down-keys to change it.

Press enter twice to verify that RIB serial port is set to COM1 (which is our virtual serial port). When you’re there, use F3 to go to the PC configuration. Press Enter at the credits screen and press F9 to go into the setup menu. Type gp300 and press Enter to start the programming software. Switch to the directory by typing c: and pressing Enter.

Mount the GP300 software directory with the following command: mount c /path/to/the/directory Mount the directory and adjust the CPU cycles (211, not 192!). You can now press Ctrl+F11 several times to bring the CPU speed (cycles) down to ~211. Start DOSBox (you might need administrative/root privileges to use the serial port). Unzip this file to a subdirectory – remember the path. It’s often called GP300.ZIP and contains several files, including a GP300.EXE and a GP300.MDF. You’ll need to have the Motorola GP300 RSS software to program the radio. As my USB adapter is at /dev/ttyUSB0, I’m using the following configuration: serial1=directserial realport:ttyUSB0 Required software On Linux, an example might be ttyUSB0, on Windows it would be something like COM3. Make sure that you use your real, physical COM port instead of COM1. Scroll down to the section in the file.Įdit the serial1 line so that it matches the following format: serial1=directserial realport:COM1 Open the file with your favorite text editor.
The configuration file for DOSBox is stored in. Go to Start → All Programs → DOSBox- → Edit Configuration If you’re using Linux, start DOSBox once – it generates the config file on the first start.

Because of that, we’re going to use DOSBox.ĭownload it from and install it. dev/ttyUSB0 Downloading and configuring DOSBoxĪs I mentioned earlier, we have to use MS-DOS to program the radios.
If you’re using Linux, you can read the syslog or enter ls /dev/ttyUSB* (if you’re using a USB adapter, if you use an internal port it might start with ttyS) in your terminal: ls /dev/ttyUSB* If you’re using Windows you might want to do that in the device manager (Win + R → devmgmt.msc) – serial devices start with COM and have a number at the end, e.g. Software setup Finding the serial portįind out the serial port. When connected to the 9V battery, the red LED on the RIB-less cable should be on. From left to right: RS232-USB, 9V battery, GP300 with RIB-less cable You have to remove the GP300-battery and use the RIB-less “cable”. This includes the 9V battery with the VCC/GND wires, the DB9 serial port and the GP300 itself. That’s the easy part: Connect everything. You can buy those “adapters” on eBay pretty cheap.
