Home / I-Opener Areas / I-Opener Technical Info Reference (MODERATED) CN13 Pinout Serial port pins found

CN13 Pinout (modified 0 times) gaelic Profile I've managed to trace at least the serial port connections of CN13 (the one the modem is on): Pin Signal Signal Pin 16 GND o o Reset 15 14 ??? o o ??? 13 12 RI o o CTS 11 10 ??? o o VCC 9 8 RTS o o DSR 7 6 DTR o o TXD 5 4 RXD o o DCD 3 2 GND o o< VCC 1 (If the graphic looks screwy, copy it and use a fixed font to view it.) Reset should be active high, the polarity of the rest are still being looked at. This is certainly a TTL level connector. 05-03-2000 18:32:42

RE:CN13 Pinout (modified 0 times) ryan/gopher0x yep thats what I got too... and pin 14 is sound out to speakers!!!! 05-04-2000 17:08:52

RE:CN13 Pinout (modified 0 times) RedLine So are pins 13&14 Line-in's to the Yamaha chipset (with the common ground), or are they just (+) and (-) for a mono-in? This makes sense, cause the dial-tones have to get to the sound card somehow! 05-05-2000 12:29:00

RE:CN13 Pinout (modified 0 times) gaelic Checked, the signals are inverted - that is they are intended to be put into a standard inverting RS-232 driver chip without modification. 05-09-2000 15:08:02

RE:CN13 Pinout (modified 0 times) gaelic Hate to do it, but so that others can find this with a search: COM1, RS232, port Also, apparently the HTML editor removes extra spaces, or maybe my browser does, anyway, even after copying, pasting and using a fixed font, you need to add some whitespace to get it legible. 05-09-2000 15:31:42

RE:CN13 Pinout (modified 0 times) goper0x/ryan well I just took a AAA battery and put the neg end to pin 16 (GND) and the positive end to pin 14 ... and i got some poping, and humming from the speakers..... so i figure its just pin 14 .... but im not real sure. and I do know that none of the CN13 pins are routed to the phone jacks, that what th elittle wire that jangs off of the modem is for. 05-10-2000 07:38:06

RE:CN13 Pinout (modified 0 times) Tackhead I'm thinking a small piezo element could be squeezed into the case and glued onto the modem board for folks (like me) who like audible modems. This would free up the signal being sent to the Yamaha. Roastbeef: Can you do us a favor and look at the quality of the sound outputs with both modem-plugged-in and modem-unplugged? I just had a horrible "wow, what a design-flaw" kind of hunch, and I'm too far from an IO to check continuity between the speakers-and-the-modem versus the yamaha-and-the-modem. On an unrelated note - and this should probably be in the "random technical stuff" board - has anyone thought about the feasibility of shielding the clock circuitry that seems to be the source of much of the noise inside the case? 05-10-2000 09:17:55

RE:CN13 Pinout (modified 0 times) 0delay As mention this is conneted to a TTL driver chip. Do we just need a Rs232 inverter driver ... do you know a current part number? As with Prefects com2 mod, is there any way to use the rs323 driver ship as an inverter? Nice work by the way :) Since I removed the modem I might just desolder the phone jacks and drop in two serial connectors in their place. ass for the volume, since I removed the modem my vol seems to be almost non-existant. I a m gonna plug my modem back on and see if the volume return.. I swear it was louder when it played the demo. no clue 05-10-2000 14:52:57

RE:CN13 Pinout (modified 0 times) GinJa Profile Has anyone got this pinout working for a serial port? I cannot seem to get it to work. Can someone verify this for me? BTW i have com2 cn12 working already using Prefects com2 mod. 01-01-2001 09:45:51

RE:CN13 Pinout (modified 0 times) GinJa Profile Answer to my own question is yes I did do something wrong, dahh. This pinout is correct, sorry about that. 01-01-2001 17:52:00

RE:CN13 Pinout (modified 0 times) r_fl_z Profile | Email Seems to work here, though not tested extensively yet. 01-02-2001 02:30:41

I-Opener Modem (modified 0 times) HiRez Profile Silly Question #42 Has anyone tried to take the built-in modem out, slap a DB-9 on it and plug it in to some other box?? If so, the results..... AND/OR ... move the modem elsewhere in the case so as to fit a SMC USB 10/100 in the case? Good Friends Help You Move, Real Friends Help You Move Bodies. 01-10-2001 14:01:32

RE:CN13 Pinout (modified 0 times) Skypilot Profile | Email I found this link that describes how to make a TTL to RS-232 cable. http://www.seattlerobotics.org/encoder/aug97/cable.html My thoughts though were instead of mounting inside a cable, to mount a small board in place of the modem with the MAX232A circuit on it and connect direct to CN13. I could then either add a DB9 connector or try and wire to one of the modem jacks (preferred). In looking at the circuit, I confess I don't know what "vcc" is and what it would connect to. Would any of you electronic whizzes try and translate and tell me what connections from the converter diagram go to what pins on CN13. I plan on using this to connect one of those GPS units to. Does anyone have a suggestion of how to power the GPS unit instead of through the PS2 keyboard input. Could they all be taken off of CN13 an incorporated into this board so you only had one connection to the back of the IO? Skypilot - "Keep the blue side up" 03-16-2001 23:13:00

RE:CN13 Pinout (modified 0 times) Skypilot Profile | Email Ignore the previous post. I found the answer on another thread that described exactly what I wanted. Skypilot - "Keep the blue side up" 03-16-2001 23:16:05

RE:CN13 Pinout (modified 0 times) redwood Profile ok, I've been reading, and, I"m a bit confused... regarding Perfect's serial port.. does VCC, on CN12, hook to the VCC on the MAX chip? all the other connectors have lines drawn thru, to connect... I see, the RX, RTS, TX, and CTS lines run thru, these, I think I can follow. the capacitors and their location looks simple ( I guess there is NO + or - to worry about here, ie: each leg is the same? I suppose, ground, can be connected all together, at each place? btw, my etrex GPS, uses 3 volts, so, I am geting power from the 12 lighter connector in my car... so, will I even Need to connect VCC? thanks, after finally assembling my parts, I'd love to do this Right, :) thanks! 09-03-2001 18:38:34
