2.2 DESCRIPTION
The Patton Model 590A/591A RS-232 to RS-232 Optical Isolators
offer a simple and effective way to guard your asynchronous data and
equipment from the hazards of ground looping. Plugging directly into
your DTE hardware, the Model 590A/591A provides 2500V RMS of DTE/
DCE isolation. The Model 590A/591A supports data rates to 19.2 kbps
and Model 591A supports up to 115.2kbps.
The Model 590A/591A isolate four RS-232 signals. In addition to two
data lines (TD, RD), Model 590A/591A passes one user-configurable
control signal in each direction. That makes it perfect for applications that
require hardware flow control. Just plug it in between DTE and DCE
equipment—no external power is required. Standard DB-25 female con-
nectors on both sides connect to the equipment ports.
