I tried the greenkeys list, but to no avail. So let's see who knows what
I recently acquired a pair of these RS-232 -to- CL converters. They are
branded "ED&M" or possibly "EDeM" - but they seem to have been made by an
outfit called Camiacs. They are marked Model V or Model 5. The circuit
boards are marked "CAM 25-116A" in one corner.
Photos can be seen here:
Does anyone have documents for these units? They have several sets of
internal jumpers, to configure various RS-232 parameters as well as passive
/ active states for the current loop side - Rx+ / Rx- Tx+ / Tx- etc.
Any ideas? Any documents?
Thanks in advance!
