Hey all,
Does anyone happen to have a manual for the EIA-232 current interface made by Teletype? I've found manuals for other brands, but they don't seem applicable to this one. 
This interface doesn't seem to have a model number on it. It's a black, rectangular metal box, about 8" long x 5" wide by 3" deep (estimate). It's got 4 terminals on one end, and a DB-25 connector on the other.
Thanks!
