4.0 INSTALLATION
The Model 592/594 requires no configuration. It plugs directly into
the DTE and connects to the DCE by a short cable. Power is supplied
to the unit by a wall-mount adapter. Refer to the diagram below and
follow the instructions to install the Model 592/594.
1)
Plug the DB-25 female connector labeled “DCE” of Model
592/594 directly into the DB-25 male RS-232 port on your
DTE device (PC, terminal, host, etc.). If your DTE device has
a connector other than a male DB-25, or if you need greater
distance from the RS-232 interface, use
straight through
cable.
2)
Connect the DB-25 female connector labeled “DTE” on the
Model 592/594 to your DCE device.
3)
Supply power to the Model 592/594 using the wall-mount AC
power supply included with the unit. The AC power supply
provides 5V dc @ 300mA to the board.

2.2 DESCRIPTION
The Patton Model 592 and 594 RS-232 to RS-232 Optical
Isolators guard your asynchronous data and equipment from the
hazards of ground looping. Plugging directly into your DTE hardware,
the Model 592/594 provides 2500V peak of DTE/DCE isolation. The
Model 592 supports data rates to 19.2 Kbps. Model 594 supports rate
up to a quick 115.2 kbps! Power is supplied by an external wall-mount
AC transformer.
The Model 592/594’s isolation capability not only guards your RS-
232 TD and RD signals, it also protects the RTS, CD, CTS, DSR, and
DTR control signals as well. The Model 592/594 is easy to install, and
is transparent to flow control between connected devices -- you can run
hardware
or software control! A DB-25 female on the DCE side plugs
into your DTE device and a DB-25 female on the DTE side connects by
cable to your DCE device. The Model 592/594 is made in the USA.
Warning: This product will not provide complete protection should your
equipment or building be subject to a direct lightening hit.
