Digital inputs
Using the
Inputs
tab (see Figure 2.81 on page 2-118 ) , you can configure up to 24 digital inputs
that allow you to remotely control various operational characteristics of the transmitter.
Unless otherwise noted these inputs are only accepted by the transmitter if the remote/local
status is set to
Remote
. That setting can only be made by a local user using the front panel
AUI.
Nautel presets the digital inputs prior to shipping. See the NV10/NV7.5 Installation Manual for
a list of default inputs and outputs.
Select the desired digital input (1 through 24) from the list. The
Channel
and
Control
settings
for the selected input, as well as the current logic level (1 or 0), are displayed on the right-hand
side of the page. You can define the
Channel
and
Control
settings as follows:

(telling the system to provide RF power, if pos-
sible) or the
RF Off
button on the local AUI. There are 2 inputs configured by default;
one for
Falling Edge, Turn On
and one for
Falling Edge, Turn Off
.
•
Reset
. Causes a system reset. Same as pressing
Reset
button on the local AUI.
•
Inc/Dec RF Power
. Activating these inputs will increment/decrement the preset power
level by a fixed amount (100W). Holding the selection will increment/decrement the
power level by 100W every 1/2 second. There are 2 inputs configured by default; one
for
Active Low, Increase
and one for
Active Low, Decrease.
•
Main Exciter
. Selects the main exciter to operate the transmitter. There are 2 inputs
configured by default; one for
Falling Edge, Set to A
and one for
Falling Edge, Set to B
.
•
Auto Changeover Enabled
. Sets the exciter changeover function to operate automati-
cally. There is only 1 input configured by default; each subsequent activation of the
input will toggle the state (enabled/disabled) e.g.
Falling Edge, Toggle
.
•
Watchdog Asserted.
Allows the user to assert a watchdog reset to the AUI, thus
rebooting the AUI via a hardware parallel remote input (controlled by a third party
remote control unit).
