Okey dokey, thanks for the heads up
ok so i just wanted to post all the pinouts we know of right now..
So i am going to hook pin 2 on the serial plug, to pin 1 on the controller
Pin 3 on the serial plug to pin 3 on the controller
and pin 5 on the serial plug to pin 2 on the controller (i am assuming that B- is the ground for the interface, because on the 1236 controllers the the B- is now designated a I/O ground.)
My only question is that should i switch the TX and RX on the serial plug around so that the RX pin on the controller is going to the TX pin on the serial plug, and vise versa? That just seems more logical just like the handshaking null modem diagram.. IE.. the controller's TX (transmit) would go to the PC RX(recieve), and the Controllers RX(Recieve) would go to the pc's TX(transmit)
BTW im using a USB to RS232 adaptor on my laptop.. so i dont have much concern for using an isolator.. if i blow anything up, it would only be the rs232 adaptor, and thats no biggie.
Also i have the molex plug that fits perfectly into the curtis controller
