[GreenKeys] Fredericks LEM-1

[Duncan Brown]

Anyone know anything about the Plantronics/Fredericks Electronics LEM-1 
Link Enhancement Module??

Looks to be a 2-channel BER tester, maybe with diversity?

It has "Mark & Space" Analog Inputs and "Data, MBC, Q, & GND" for Data 
Outputs.  No controls for data rate or number of bits.

Photos enclosed.

Only thing I could find on the Internet was someone selling a manual & 
data sheet, but listing was 11 years old & his email address doesn't 
work anymore!

Thanks,

Duncan
