Well, I goofed and sent this post from my other email address that isn't
registered. Trying again from the correct email address.
I came across a couple of what appear to be motor start controls in a box of
RTTY parts I picked up at a hamfest recently. These are marked MULTIPLEX
COMMUNICATIONS INC, Long Island, NY, Model MC110. There's a barrier strip
w/ contacts for Line +/- , Selector 1 & 2 and a switched 1/6A 120V outlet.
The units are marked 5 Minute Delay, which I take to mean when the line
contacts go high, the timer starts. My assumption is a teleprinter in
series with the box would then power up and remain so for the 5 minute
duration, ready to receive a message?. A google search yielded nothing
Does anyone have any info on these units?
Regards,
John WD8INC
