NETWORK MONITOR
The N
ETWORK
M
ONITOR
is activated by selecting option five on the M
AIN
M
ENU
screen. The N
ETWORK
M
ONITOR
allows
real time viewing of all networks and nodes presently operating in a Crisis System. This screen should be used
by technical personnel to verify network operation during installation and trouble shooting. The N
ODES
shown are
as seen by the master of that network. F
REE
, R
ETR
, and R
XERR
are master information as well. To return to the
M
AIN
M
ENU
at any time press E
SC
.
When a node number is displayed steady (not flashing on and off) and the error columns are zero and/or not
incrementing then those nodes are 'on-line' and working. Node numbers that are flashing may also increase the
RETR and RXERR counters and indicate a trouble on that network. This could be due to an internal failure in a
node or a poor data connection in the network.
If the network has excessive traffic, the FREE pool of elements will become depleted. This could lead to loss of
communication with this node or network. Excessive traffic can be caused by one defective node, poor quality or
damaged data pairs.
