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 2025 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. Since there is
only one indicator, it uses different LED codes to demonstrate various
messages. The following chart describes these codes:

4.0 INSTALLATION
The Patton Model 2025 is very simple to install. Once you have
configured the DIP switches, just plug it in like a normal cable and
you're ready to go. Figure 3 illustrates the proper connections for the
standard cables. If you have special-ordered a non-standard
connector, your connections may be different.
