Proper DB 25 to DB 9 cable diagram

[stagemanbob]

Hi,

Does anyone have clear wiring diagram to make an adapter from TI 25 pin serial to a standard db9 male connector? I have a lantronix device that I want to use term 80 with.

Thanks in advance.

I have a couple DB25-DE9 adapters that I use.... I can MAP them out for you....

That would be great! I have the parts just need a little clarity.

The problem is that there's no "standard" nine-pole D-sub for RS232. There's a de-facto standard, used by today's PC (or rather the USB-serial converters you have to use), but then it's still a question about if your deviced is a DTE or DCE. The pinout is different.

This is the pin out of the lantronix unit:
