[time-nuts] Ultralink WWVB receiver manuals?

[John Ackermann N8UR]

I just acquired an Ultralink WWVB timecode receiver -- more 
specifically, model 301 receiver and model 333 decoder.

I'm looking for documentation on these guys.  Anyone have a manual 
they'd be willing to share?

The key questions are really just two:  (a) is the 6P6C modular cable 
connecting the receiver and decoder straight, or reversed, and (b) what 
are the four DIP switches on the back of the 333 used for?

Thanks for any info.

John
