Now that I have confirmed Insane Multitasker's TELCO/WiModem232/TI-RS232 cable configuration (also confirmed by BerryMiller) with the BOB (break-out box), I am ready to create a cable. I am going to use one of the many obsolete Ethernet CAT5 patch cables that are laying around, taking up space (I just can't seem to get rid of old cables). The patch cable along with DB25M/RJ45F modular adapters will work nicely. Not that I don't have DB25M shells, pins, cable, crimper and pin extractor tool handy (I have wired many a building back in the day using serial connections), but these things are just so handy and easy to use! For those of you who do not know what a DB25 Modular Adapter is it looks like this:
I got them online from http://www.dalco.com...5rj45-male.aspx
Color coded, just push the pin into the numbered socket and there ya go! Plus, if you need a longer cable, simple, you just use a longer patch cable!
Pinouts: 1-1, 2-3, 3-2, & 7-7. The color code I am using is WHT=Frame Ground, RED=Transmit, GRN=Receive, & BLK=Ground. On the first adapter ((DTE (Data Terminal Equipment) = (TI RS-232 Card)) the pinouts are: 1-WHT, 2-RED, 3-GRN, & 7-BLK and on the second adapter (DCE (Data Communications Equipment) = (WiModem232)) the pinouts are: 1-WHT, 2-GRN, 3-RED, 7-BLK. Of course, after you build the cable it doesn't matter which side of the cable you plug into the TI-RS232 or the WiModem232. The connections will be the same.
Well, there is most likely a more concise and easier way that I could have posted about this... I digress...
