Yes indeed. I have several of those, model 745
as one example, and it
is a DA15 for which I have the pinout and made a cable for hooking to
various old micros here.
Is that posted/can you post that cable pinout somewhere? I've got a
number of those models and have never been able to attach anything to
those ports.
Hey Jason--
It's here, (Thank You Al)
http://www.bitsavers.org/pdf/ti/terminal/silent_700/984025-9701rC_743_KSR_7…
page 2-3, table 2-1 (pdf page 13).
I think the terminal is normally supplied with a "loopback" plug
(that's almost always missing) that goes into that DA15-M and loops the
"printer/keyboard interface" to the "communications interface" when
you
are using the onboard acoustic coupler. If you want to talk to a local
host not over the modem, then you remove that loopback plug and plug in
your own cable that goes to your host.
I made this cable with DA-15 female on one end and DE9-male on the other
so that this terminal would look like a PC serial port and connect to
various DCEs such as a terminal server and other stuff I have here wired
for direct connect to a PC comm port,
DA15-F DE9-M
1 5 GND
11 1 CD
12 2 RXD (to the terminal)
13 3 TXD (from the terminal)
15 4 DTR
Keep on the lookout for a model 787 manual. This thing is cleaning up
quite nicely and I hope to put the juice to it later today or tomorrow.
It was found on the floor of a garage-- that would be the dirt floor.
Not cool and it looked pretty rough on the outside but hoping it's still
happy on the inside ;-)
