Cable Re-creation

Greetings All,

I have an issue that should be easy, but apparently not for me LOL. An old automation equipment became obsolete at our plant and I was told I could gut it for anything before it was sent out for scrap.

I removed a SLC500 Fixed I/O, and a DTAM Micro, (both very old I know, however in excellent condition). The PLC as you are aware has a RJ-45 (RS485) port, and the DTAM Micro has a DB9 (also RS485) port.

Whomever built this unit used an ethernet cable for the PLC and cut one end off and soldered in a male DB9 plug for the DTAM.

The cable was snaked through a lot of conduit, and I could not easily remove it, and when I came in to work the next day, the whole assembly was already gone for scrap!

I want to remake the cable, however I do not know the RJ-45 to DB9 pin connections and although as I said the hardware is old, I see no reason in using it for something, and obviously do not want to make a wrong pin connection and harm either units.

Can anyone help me out with the pin-outs?

Thanks,
Corbis

It may be of some help.

I believe the pinouts you need are in this manual.http://www.spectrumcontrols.com/pdfs/soi/DTAM_Micro_Manual_0300209_1A.pdf

Excellent

I expected a fast response, but you guys are incredible.

I will make the cable tomorrow. Thank-you very much !!!
