Clean excess solder with some copper wick. You can also use a regular fine-tipped soldering iron and place a big solder blob along one of the rows of pins, then lift up gently, repeat on the other side. Removing the SP213 can be done in various ways – if you have a hot air gun, you can clamp it with tweezers and hold the board up a few millimeters while you slowly heat it, until the board falls down from under the chip. As can be seen in the chip layout, the inputs to the FTDI are next to each other, so a simple solder ball will bridge them, and T1IN/T1OUT will have to be bridged using a wire. In this particular converter, the pins used are R4IN/R4OUT, and T1IN/T1OUT.

Similarly, the data signal coming from the serial port into pin RxIN at +10/-10 volts is converted to TTL (0/+5 volts) out of pin RxOUT. The TTL signal going into pin TxIN is then converted to a +10/-10 volt signal out of pin TxOUT. The TX and RX pins of the FTDI chip are connected to TxIN and RxOUT pins on the SP213 respectively. Once you finish the cuts, carefully pry the two plastic halves apart, until you have something that looks like this (the SP213 is the large chip): On some of these devices, the plastic is not fully opaque, allowing you to see where the circuit board’s edge sits. With great care to not cut too deep (you risk damaging the components on the circuit board!), use a Dremel or sharp pen knife to make an incision along the red line: The adapter used here is available in many local shops where I live, but any similar converter will do the job.
The first step is to cut open the overmolded plastic, so that we can work on the circuit unimpeded. The looks of the USB adapter prior to the procedure are shown in this picture: Part I – Open-heart surgery on the USB adapter It should be easy to remove the Sipex chip, and bridge the FTDI directly to the DB9 connector, thus creating a direct USB to TTL serial port adapter. These converters all share some common traits – they sport an FTDI USB to serial converter, and a Sipex SP213 or similar TTL to RS232 level voltage converter.

was an expensive proposition) was to tweak a readily-available USB to serial port converter into a pseudo-RIB, and then making patch cables with the electrical and data bus configuration each radio model required. But, the gremlins had managed to lose my RIB box and cable kits, leaving me unable to do anything useful with the radios I was given.Ī tinkerer as I am, the first thing that came to mind after thinking about the various options I faced (purchase a new set of RIB boxes, cables, etc.

I have worked with Motorola equipment plenty of times, and have over the years purchased RIB and cable kits, and RSS and CPS software to match.
Recently, I was given a couple of Motorola Radius GM300 mobile radios, a GM350 and a set of three GP320 one-channel handhelds.
Part of my duties at my local Fire Department where I am a volunteer is to take care of the radio communications, be it maintaining the repeaters and base stations, to installing new gear and training probies in the art of radio.
