DCS port on I Game

(1/1)

iwalker:
Attached is Backplane schematic for a 039 board to troubleshoot DCS port (Channel2).

mozart:
It's similar to what I have. The DCS is identical, but I have it under J6. Thank you for posting!

mozart:
Just in case someone is looking to get the DCS port working:



Here is the recipe: I'm using a USB-TTL jumpered to 5v FTDI adapter, and the only pins in use are RX, TX and GND in the adapter end, going to 5, 9 and 2 on the DCS, respectively. The power provided to the DCS port pin 7 is 13v (not 5v as my previous assumptions), so basically I loop back 13v from pin 8 to 7. I also loop agnd from pin 1 to 3, to ground the power circuit.


So communications run on 5v but the internal DCS circuit needs 13v (which it has on pin 8!!).


I'm not sure if this is the correct way of doing this, but I have it synced since this morning and she runs fine.
