OK... I know this may be out of the realm of many of you, but hoping someone here has experience with a Telex IP-223 and hopefully a Kenwood radio, I'm looking at a Kenwood TK-7180H. In a truck that I help maintain, we have several Telex IP-223 devices, that connect to our mobile radios so we can transmit/receive radio over an Ethernet connection. The radios in the truck were all installed prior to my involvement but I do know that one of our IP-223s has a radio connection available (each module can control two radios). We currently have two 800MHz Motorola XTL-5000 radios, two VHF-high band XTL-5000 radios, two VHF high-band XTL-1500 radios, two VHF lo-band radios (both Motorola but I don't recall model), and three UHF Motorola radios with with varying band coverage. That makes 11 radios when we can support 12. Actually, we have a 13th IP-223 that is doing nothing, as we planned on adding a telephone option but never did. Anyway, we plan on adding a Kenwood TK-7180H specifically to decode FleetSync II with GPS. All of the portables that we issue are Kenwood radios and we are adding external GPS microphones to them. The back of the TK-7180H has a DB25 connector, which I believe carries RS-232 data we will need to tap to a computer to decode. I believe it also carries the needed lines for connecting to the IP-223, meaning we will need to create a custom DB25 connector that connects both to a computer and to the IP-223. The issue I'm asking about is what pin numbers on the radio correspond with what pin numbers on a DB9 serial port to the computer and what pin numbers on the radio correspond to what pin numbers on the DB25 connector on the back of the IP-223? I'm looking at the service manuals of both the radio and the Telex device but it appears they are using different nomenclature on their pinout diagrams.
