The pin-outs are the same on the BCD input connector, but how the
high-order controls map differs between models.
For example, the PTS-160 doesn't use the 4-bits for 100 MHz, but rather
takes input on the 10 MHz bits up to a value of 16. The PTS-250 does use
the 100 MHz bits, with values of 0, 1, or 2 as possibilities. One might
expect the PTS-160 to respond to 0 or 1 on the 100 MHz inputs, but that
isn't the way it is designed.

Yes, the pinout is the same for all models. If anyone is interested, I have
the manual for the PTS-3200 and can send the interface pinout.

Thanks, Nigel, I think your history description is about right - I
vaguely recall seeing the Rockland brand too. I guess PTS is the
current survivor - the PTS D310 seems quite new, and the company
seems to be still in business in their niche.
Ignacio sent me a pinout page for the PTS 040/160/250, which probably
represents a standard arrangement used for all the models, hopefully
just extended by including more bits for higher frequency units. The
D310 is a dual .1 - 310- MHz type, with two program connectors. Also,
I do recall that they used IEC color codes on the ribbon cables for
convenient tracing of the 8,4,2,1 bits within each BCD digit, so it
should be fairly easy to figure out the details.
