I have an old 1988 triac, I have tried to connect the machine to a computer with no success. I made up a cable as described in the manual, unfortunatly the connections to the 7 pin din and the computer comms port don't appear to work. It may be coincedence but the y drive fused last time I tried.
Has anyone the correct connecting cable or can you confirm the connecting pin configuration.
PS can I bypass the 7 pin din and go into the main board?

If you suspect the DIN socket is a bit old and cranky, I'd definately go straight to the board.
I'm sure the schematics are on here (or on the main website legacy downloads page)
I might also try just the two wires for TX and RX first -
If things are blowing, I'd also think about getting a serial protection device - or at least use a PCI / ISA comms card that you can replace easier than a new motherboard

Here's a quote from an earlier post about an Easimill
The same goes for the Triac PNC controller - it's a perfect test to make sure the machines RS232 link is OK

Here's a test to check that the machines RS232 is OK...
- Turn the power switch at the back of the machine OFF
- Disconnect any RS232 cables from the machine
- Turn the power switch back on
- Press the 'T' key (this must be the first key you press after powering on)
- The controler shows a self-test screen. At the the bottom it says something like
Serial Link : O/C
Indicating that the serial link is Open Circuit. Now short out the transmit and receive pins on the round rs232 connector (pins 6 anf 7 - a paperclip was always good for this. The display should change to
Serial Link : S/C
Tha machine is now sending characters out of it's transmit line and checking that they are coming back in on it's receive line. If you get the 'S/C' then the controller software and hardware are all OK!
Hope this helps !
(I seem to remember that the 'S' key shows the software version, and the 'K' key allows you to to a keyboards test too)
