This warranty is limited to defects in workmanship or materials, and

If this product fails or does not perform as warranted, your sole

condition shall Patton Electronics be liable for any damages incurred

1.1 RADIO AND TV INTERFERENCE

The Model 592/594 generates and uses radio frequency energy,
and if not installed and used properly—that is, in strict accordance with
the manufacturer's instructions—may cause interference to radio and
television reception. The Model 592/594 has been tested and found to
comply with the limits for a Class A computing device in accordance
with the specifications in Subpart J of Part 15 of FCC rules, which are
designed to provide reasonable protection from such interference in a
commercial installation. However, there is no guarantee that
interference will not occur in a particular installation. If the Model
592/594 does cause interference to radio or television reception, which
can be determined by disconnecting the RS-232 interface, the user is
encouraged to try to correct the interference by one or more of the
following measures: moving the computing equipment away from the
receiver, re-orienting the receiving antenna and/or plugging the
receiving equipment into a different AC outlet (such that the computing
equipment and receiver are on different branches).

1.2 CE NOTICE

The CE symbol on your Patton Electronics equipment indicates
that it is in compliance with the Electromagnetic Compatibility (EMC)
directive and the Low Voltage Directive (LVD) of the Union European
(EU). A Certificate of Compliance is available by contacting Technical
Support.

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.

When installed according to the instructions above, the Model
592/594 is designed to operate transparently–just set it and forget it.
There is no ON/OFF switch; the unit is operational as soon as power is
supplied.

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 RS­232 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.
