Model 5130
Party-Line Interface Module
apply power while continuing to press the
button. The module will go through its nor-
mal power-up sequence and upon comple-
tion light one of two LEDs. If the Model
5130 is configured for operating mode 1
the CH1 TO –18 LED will light. If the
module is configured for operating mode 2
the CH1 TO –12 LED will light. Refer to
Figure 7 for details. From the factory
the Model 5130 is typically configured
for operating mode 1.
If the button is released within a few sec-
onds of the LED displaying the operating
mode no change will be made and the
Model 5130 will begin normal operation.
However, if after the operating mode is
displayed, the auto null button remains
pressed for approximately five additional
seconds the mode will automatically
change (“toggle”). For example, if the “–18”
LED indicates that operating mode 1 is the
current configuration, continuing to hold the
auto null button will cause the configuration
to change to operating mode 2. It should
be very clear that a change has occurred
as the LED will change from “–18” to “–12.”
After the change has occurred, releasing
the button will cause the revised configura-
tion to be saved and the Model 5130 will
begin operation under the revised mode.
When described in words this procedure
seems fairly technical. But a couple of
practice sessions will show how simple
it actually is.
