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.
