Re: [ts-7000] Re: On 7800 cannot use ttts4 or ttts5 (com3 header)

[Eric Robishaw <>]

That would make sense... I'll check that out, though I can't find ANY documentation with the dsub pinouts for the com ports.
Not in the schematics, getting started sheet, "manual", or the mechanicals.  Thanks TS!

Hi Eric,

Are you counting the pins on the header correctly? - TS tend to use DSUB pin ordering 1-5 on the side with the square pin (see mechanical drawing for position) and 6-9 on the other side for their COM headers.

On my TS-7390 I'm having issues with data corruption, and I'm about to get the scope out to measure the actual baud rates being sent between the devices.

Hope this helps.
