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 2036 and 2037 feature an easy-to-read LED that shows
the operating status of the Model 2036. Figure 1 (page 4) shows the
location of these LEDs. The following chart describes the LED’s status
codes.
Please refer to the following key to interpret the above status
codes:
