Using the I/O Points with InSite
™
NMS Software
InSite software has the ability to read the user analog input (
Analog 1
) and two
user-configurable and independent I/O signals (
I/O 1 & I/O 2
). Each I/O
connection can independently configured as input or output. If configured as
an output, a
saved
default output value can be stored in the radio to ensure the
radio boots to the desired state for this pin.
The values of
I/O 1
&
I/O 2
can be read and displayed by an InSite user to
determine the current state. The values of
I/O 1
&
I/O 2
at the TransNET’s
DATA
Interface connector will remain in a constant state until manually
changed though the InSite
Configuration
screen.
Application Example—Digital Input/Output at Remote
A typical application of the user I/O connections may require one digital input
and one digital output to be controlled by network diagnostics. In this
example,
H3
could be jumpered to
H7
(I/O 1
to RJ-11, Pin 1) and
H4
jumpered
to
H8
(I/O 2 to RJ-11, Pin 2). Using InSite,
I/O 1
could be configured as an
output and
I/O 2
as an input.
