You can untick the checkbox, which would turn off the buffering completely, but that does not seems to have any effect on this problem (so far).8 Pin USB Programming Cable for MOTOROLA Mobile Radio GTX GR400 GR500 GR1225 SM10 MCX760 MCX780 PRO3100 PRO5100 PRO7100įor Mac, Windows XP, Vista, 7, 8 OS 32 bit and 64 bitĬable driver included in the disk or sent by emailĭesktrac, GM140, GM160, GM300, GM328, GM338, GM339, GM398, GM399, GM340, GM360, GM380, GM3188, GM3688, GM640, It uses sliders and RX is 1-14 (because that’s the size of the buffer in the UART chip) and the TX buffer is 1-16 characters. Regarding FIFO, Windows 7 advanced settings do no permit setting RX to zero. It would help a lot though to know what ALL of your port settings are set at, not just baud and FIFO. I’ve tried experimenting with the handshaking (XON/XOFF, hardware, none) to no effect, but this was with DOSbox and RSS running, so changing the settings without exiting and restarting DOSbox may not have any effect. This makes me believe the problem is a handshaking issue, that either the radio or the computer is not pausing when it should.

At the same time, in the DOSbox status window I’m seeing a serial port error that the RX buffer overflowed. Attempts to read the radio result in the same error displayed and failure. Under Win 7 and the latest DOSbox I get the error flashing on the screen very briefly and then the “Radio Communications OK” message when testing the comms. The cable is from KJ6ZWL, as is the RSS software.

The PC I’m using is one I built myself, specifically for amateur radio, so it does have a native serial port. Second, like many others here I’m also encountering the “Error #7 INVALID OP CODE” problem. Now it’s time to configure the RSS, and test the connection between your computer and your Motorola Radius.įirst, my compliments on a great resource you’ve created here. I was able to successfully program with a CPU Speed of up to 400 cycles. If you went too far, hold down the “Ctrl” key and press “F12” to raise the speed back up. While DOSBox is running, hold down the “Ctrl” key and press “F11” until the CPU Speed (displayed in the title bar) reaches somewhere around 191 cycles.

Now let’s go over how to slow down the CPU speed. We already discussed what cables worked for me. Cheap programming cables, and too fast of a CPU speed (on your computer/DOSBox) are the main cause of this problem. getting your Motorola Radius to communicate with your computer. Now comes the part that just about everyone has trouble with. If you see this screen above, congratulate yourself! You have successfully configured DOSBox to run Motorola’s Radio Service Software. You should see a welcome screen that tells you to push any button, and then the following screen below. Now it’s time to see if we did so far is correct.

Starting Motorola’s Radio Service Software The Device Manager can be accessed by bringing up the Start Menu and typing “Device Manager” in the Search Programs and Files area. This can be accomplished by checking the Device Manager. We now need to make sure that the USB Serial Port Adapter has been assigned port COM1 or COM2. Note: If you have an existing serial port on your computer, just plug your Motorola RIB to the computer and the Motorola programming cable to the RIB and your transceiver. Finally, attach the programming cable to the RIB and your transceiver. Attach the Motorola RIB to the USB Serial Port Adapter. Plug in your USB Serial Port Adapter to your computer. The first thing you need to do is get your hardware setup. Getting Setup to Program the Motorola Radius I had to trash two different USB serial port adapters before I found one that worked for me. WARNING! – Some cheap USB serial port adapters do not work to program your Motorola Radius.
It is best to use the recommended cables and connectors listed above.
There are other programming cables that may or may not work to program your Motorola Radius.
