3.0 CONFIGURATION

The Model 2039 is simple to install and designed for excellent
reliability The following instructions will help you set up and install the
converter properly. If you have any questions, please call Patton
Technical Support at [phone].

3.1 CONFIGURATION SWITCHES

The Model 2039 uses a set of eight external DIP switches (see
Figure 1) that allow configuration to a wide range of applications.
Because all eight switches are in one externally accessible DIP switch
package, there is no need to open the case for configuration. The
configuration switches allow you to select data rates, parity, word length
and flow control selection. The following section describes all switch
locations, positions and functions.

The Model 2039 uses a

miniature

configuration switch package.
To configure your unit, use a small screwdriver and gently push each
switch to its proper setting. The ON and OFF positions are shown in
Figure 2. Default settings for the DIP switches are shown in the table
on the following page. Detailed settings follow the table.

5.0 OPERATION

Once your interface converter is properly configured and installed,
it should operate transparently—as if it were a standard cable
connection. Operating power is derived from the RS-232 data and
control signals; there is no "ON/OFF" switch.

5.1 LED STATUS MONITORS

The Model 2039 features an easy-to-read status LED that glows
red to indicate the condition of the transmission line. Figure 1 shows
the location of the LED. The following chart describes the LED's
various functions.

The red LED indicator blinks to show data activity. However, since
there is only one indicator, it uses different LED codes to demonstrate
various messages. The following chart describes these codes:

LED Codes

● ● — ● ——— ● ● — ● ——— Computer is sending data

● ——— ● ——— ● ——— Serial device is connected; computer is

not sending data

● ● ——— ● ● ——— Both serial and parallel devices are

connected; computer not sending
data
