[GreenKeys] STOP THIS NOW

I apologize for putting fuel on that fire.  It won't happen again.

I too purchased a couple CL050A from eBay.  Although I don't have
a solution for your HV keying problem, I did find the manual online
which helps figure out how to set the switches if you want to change
the DTE/DCE configuration on the RS232 side or select 20, 30 or 60mA loop,

http://emea.blackbox.co.uk/manuals/C/CL050.pdf

Interestingly, mine came with coax attached to the loop side.  Looks to
be RG62 class, 93ohm stuff.  The Tx loop was shorted out with a jumper
and the coax was connected to the Rx loop--  suggesting some kind of
receive-only application.
