Using the I/O Points with InSite™ NMS Software
MDS’ InSite 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 and Output at a 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.
