TRIAC RS232 cable

Post by jsheets » Mon 20 Apr , 2009 17:27 pm

I downloaded the ZIP file with the pin out diagram, but I do not understand what pin 5 (five) is supposed to do. I looks like it is connected to pins 2 and 3.

Please clarify.

Thanks,
Jim

Pins 1,2,3 & 5 are all Automatic Toolchanger (ATC) inputs.

Pin 1 = Arm in.
Pin 2 = Arm out.
Pin 3 = Arm up.
Pin 5 = Arm down.

The common for all the switches is pin 44 (Grnd).

TRIAC RS232 cable pin out

Post by jsheets » Tue 21 Apr , 2009 12:40 pm

The RS232 cable wiring diagram shows pin out of pins 2 and 3 going from the 9pin connector to pins 3 and 2 of the 25 pin connector. Pin 5 on the 9 pin connector is shown looping around pins 2 and 3. This is what is confusing me. What's up with pin 5 on the 9 pin connector? Also pin 7 on the 25 pin connector loops around pins 3 and 2 of the 25 pin connector.

Thnaks, Jim

Can you put a link to the diagram you are looking at and downloaded?

Pins 2 and 3 are ready transmit and recieve. the next 2 pins ( 4 & 5) are ready to send and ready to recieve.

These pins may not be used and in which case they would be linked to the ground.

Attach the link se we know what you are refering to.

Are you looking at the SCREENING?

Most RS232 leads are made using screened cable with the screen going to one of the pins. Pin 5 is therfore the screen.

Yep - pin 5 on a 9 way D-type is ground (GND)
pin 7 is GND on a 25 way
