The service schematic of the Vertex Standard VX-2200 VHF radio shows that the ACC5 and ACC6 pins of the back DB 15-pin connector are connected to pins EXT_TXD and EXT_RXD pins on the main processor.

Can those pins (or some other pins in the same connector) be used to program the radio or do I have to use the RJ45 connector in the front?

  • $\begingroup$ Hi Ronan, I think this is off-topic for ham.SE, since VX-2200 is definitely not a Ham device, but a trunking controller for people with a commercial license; see the manufacturer's website: for flexible mobile business communications in the VHF or UHF Land mobile radio bands, so you might want to explain in which context you're using the device (you can probably use it as a ham mobile device, but you're not saying) $\endgroup$ Oct 9 '16 at 14:14
  • $\begingroup$ @MarcusMüller I am actually trying to use it as a ham fixed station in the 2m band for now. The radio isn't used exclusively for trunking nor for commercial licenses, since it works from 134 to 174MHz. See the non-trunking page. Also, I'm not in the US, so regulation is a bit different, if still very similar. $\endgroup$ Oct 9 '16 at 20:05

You should be able to find the answer in their service manual. http://www.repeater-builder.com/yvs/pdfs/yaesu-vx-2100-2200v-service-manual.pdf

  • $\begingroup$ The service manual doesn't give a specific answer, although it mentions a "programming cable". $\endgroup$

  • $\begingroup$ Correct, it mentions a 15pin cable and it appears to be what was being described. $\endgroup$ Dec 9 '16 at 21:14
  • $\begingroup$ Usually something like this that requires a special programming cable also requires special software from the manufacturer. It isn't an open specification. $\endgroup$ Feb 16 '17 at 20:24
