johnph3 Posted April 19, 2022 Share Posted April 19, 2022 Success My 2017 Super AMS is working. Chalk up one more problem to a bad 74ls245. Thanks for your help 5 Quote Link to comment Share on other sites More sharing options...
johnph3 Posted April 19, 2022 Share Posted April 19, 2022 (edited) OK I have a new question? I would like to build a RS232 loop back plug so I can run diagnostic software and get a response back from rs232. I have seen diagrams in the past 5 to 8 years ago but have never taken time to build one. If you know of a site that has diagram to construct one I would like to have a link to it. Thanks in advance. I think I even saw one that had led's on it to signal traffic. Might be more than what I need though.

I'm pretty sure that the CorComp Peripheral Diagnostic Cartridge manual included the pinout for a loopback plug. Quote Link to comment Share on other sites More sharing options...
johnph3 Posted April 20, 2022 Share Posted April 20, 2022 Sorry I know we are getting off subject for this thread but do you know where I can download the Corcomp PDM manual? I just spent the last hour checking sites to try and find it. The funny thing is I have a PDM module but never got a manual. Quote Link to comment Share on other sites More sharing options...

johnph3 Posted April 20, 2022 Share Posted April 20, 2022 Yeah but I believe the TI RS232 uses a somewhat different pin out. Not sure just what I've been told. Quote Link to comment Share on other sites More sharing options...

+Ksarul Posted April 21, 2022 Share Posted April 21, 2022 The only differences for the TI cards is that they are wired DCE instead of DTE. That reverses the signals on pins two and three compared to just about every other computer system out there. The other pins are the same (but also note, the four identified pins are for port 1 of the RS-232 card, and the four pins used to communicate on port 2 will all be different, but are identified in the RS-232 manual).

+mizapf Posted April 21, 2022 Share Posted April 21, 2022 This is probably the most confusing thing about the RS232 on the TI: The TI is, by this interface, configured as an end device, as you would expect from a modem. One could imagine that you can take a "real" terminal and let it talk to the TI. This is a real challenge for emulations that have to somehow adapt the wiring to the real PC interface. In MAME, I designed a "line mapper" for that purpose (see https://www.ninerpedia.org/wiki/MESS_Serial_connection). 1 Quote Link to comment Share on other sites More sharing options...
SkyPilot Posted April 21, 2022 Share Posted April 21, 2022 Late to the party, this is a large thread, so I'll ask my question. Do any non game useful programs exist that use this card? Quote Link to comment Share on other sites More sharing options...

Whooha! Yeah, Foxit might be dead now, as SNP ver3 would take on the new task at hand. I sure hope nobody sees us skipping down the program path hand in hand, BFF.... so, please, none of that is necessary, uh..in public, even though, you have held my programming hand at some point or another...shhhh... Hope your not wearing one of those cameras on your neck tie. Edited April 22, 2022 by GDMike 3 Quote Link to comment Share on other sites More sharing options...

It should mean than a straight-through cable can be used to connect a modem, but that's about the only advantage. It's created literally decades of confusion! 1 Quote Link to comment Share on other sites More sharing options...
apersson850 Posted April 22, 2022 Share Posted April 22, 2022 The p-code system does allow you to redirect screen input and output to the RS232 port. Then you can connect a terminal to your TI and run it from the other end of the desk, or even further away. Until you need to replace a diskette or something. I'm of course convinced that it's this very common ? reason that caused them to turn things upside down with their serial ports. 3 Quote Link to comment Share on other sites More sharing options...

Great for my HDX setup as I can just plug the PC's DB25 right into the TI's port. 3 Quote Link to comment Share on other sites More sharing options...
