I need help from some of the folks who traced out the pinouts for the i-Opener for my GCT;
I just got the RS232 board from Jack at BadFlash (Very FAST delivery, Thanks) and using a 16 pin male to female ribbon cable to connect the card to the modem socket CN13 I have now a RS232 COM1. The 16 pin cable is necessary since the R12 telephone and USB ports block the end of the RS232 board and the 16 pin cable I made has the pairs reversed like the IDE cable since when you add the ribbon cable the pairs are switched if you attempt to connect it straight through and of course on one end has a male header , with the other having a female end to match the RS232 mod board.
Now what I have a problem with is that I must have been drinking when I claimed some time ago that the CN5 10 pin header on the GCT was a com port that matched at least on voltage & ground pin, this not true.
CN5 looks like this:
1 - ?
2 - +5 volt (4.93v)
3 - ?
4 - ?
5 - ?
6 - ?
7 - Ground
8 - ?
9 - ?
10 - ?
All the possible pins are there for a possible COM2 port, BUT the interesting thing is that when I hook Badflash's RS232 board to that header and power on, the unit boots but the keyboard will not respond. This is likely a fluke, even though I had the idea that CN5 might be keyboard/PS2 port???
What's the best to figure out the 8 undentified pins on CN5 and assuming it's the TTL COM2 port to indentify signels like RTS DTR SDR ?
The pinouts from the i-Opener modem and the i-Opener VGA are the same as those on the GCT, surely there is COM2!!
