Digital inputs
In the
Remote I/O
page, use the
Inputs
tab parameters (see Figure 2.92 ) to configure up to 16 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
(bottom panel of any AUI page) is set to
Remote
. That setting can only be selected by a local user
using the front panel AUI.
Nautel sets digital input defaults prior to shipping. See the NX300 Pre-installation Manual for details. If
necessary, re-configure the digital inputs as follows:
Figure 2.92: Remote I/O Input Parameters
