I’ve been modifying radios, scanners, and mobile phones for years. I’ve learned from experience that these industries are total bastards when it comes to connectors and pinouts<\/a>. More often than not, the connector on any mobile device, including phones, is some proprietary one-off thing, even when the protocol is almost invariably serial. This goes double for scanners, communications receivers, and pagers. Hell, even GPS units have bizarro connectors<\/a>. Connectors so badly designed and outrageously expensive that most people just made their own. <\/p>\n

These are the sorts of things that are only justifiable to businessmen — Yes! make a one-of-a-kind undocumented connector, and then charge loads of money for cables and connectors, because we’re the only source! You can almost hear them laughing all the way to the bank<\/del> extinction<\/strong>.<\/p>\n

I recently acquired a Uniden Bearcat BCD396XT<\/a>, which is a remarkable radio. The most salient feature of this radio is its ability to decode APCO25-standard broadcasts<\/a>, which now comprise the majority of public service frequencies like police, fire, etc. But this radio goes a step further, allowing connection to a GPS (for “location based scanning”, a funny thing for a radio device, when radio was invented to overcome problems of distance) or to a computer for complete control. Problem is, the connector of interest is wacky. <\/p>\n

This connector, though it kinda resembles USB connectors, does not transport a USB signal. It is a plain old serial connection. Why they chose to use this connector is beyond me. However, as a hacker, I want access to those pins. I could just open the radio and solder to the board, but it’s more elegant and flexible to find the connectors themselves. After taking some detailed photographs, and searching around a bit, I was able to find a replacement. <\/p>\n

Items on eBay — they can be had for about a dollar each, with shipping <\/a>— a hell of a lot cheaper than the $20 asking price for the standard serial cable. The magic search words turned out to be “4 pin mini USB cable” (most are 5 pin, these 4 pin models appear on a few odd digital cameras and MP3 players<\/a>). <\/p>\n

Please note, these cables are only good for the connectors on the end. Plugging the radio into a USB port without a proper USB adapter is asking for pain.<\/p>\n","protected":false},"excerpt":{"rendered":"
