Hello John and Greg--
John--I think he means the 8pin DIN, not the mini-DIN....
Greg--contact me off-list and I'll try to help you with the PSK-1T (even though you apparently outbid me for these items, assuming you recently obtained them ;-) ) I've been using it to command AO-16... I don't know about the DFM unit, other than I think it is probably 1200 and 9600 baud capable.
The PSK-1T can, as a stand alone unit, be used for 1200 baud PSK packet (like AO-16, IO-26, DO-64) and 1200 AFSK packet (like CalPoly-6). The DFM TNC doesn't need to be connected to the PSK-1T for it operate.
If, however, you have a PSK-1 (without the "T"), it requires another TNC to be interfaced to it (like the DFM, an MFJ, etc.).
My hunch is that the pair was used to add 9600 baud capability to somebody's satellite station...

John -
That is the easy question. When Gywn Reedy, W1BEL (sk) and others set the specifications for the external contractor build of the PacComm PSK-1, they elected to use a common pin assignment/cable (late 1980s/early 1990s) for the 8-pin mini-DIN (rear panel of PSK-1) to the RS-232 (DB-9) on your computer.
The cable for usage between an Apple computer and an Apple LaserWriter (serial port). I picked up a PacComm PSK-1 in May, replaced a blown capacitor on the 7805 regulator input and built this serial cable for connection to my personal computer's serial port. IF PacComm no longer sells this cable (you have to send an e-mail request to Linda), then any good Apple dealer or cable supplier should have this cable in their inventory for less than $25.

Hi I was wondering if some one has any manuals for the DFM TNC and the PSK-1 or the the PSK-1+?
To get me going can some one please send the pin out for the radio 8 pin DIN for the DFM TNC.
