1. Go to menu 4) and select 4I) N
ETWORK OPTIONS.
2. Enter the user password and press Enter.
3. Select 4I1) N
ETWORK CONTROL).
4. Press Enter to modify “D
ISPLAY MODE” and use
Up and Down to switch between “
NETWORK
CONTROLLER
” and “LISTEN ONLY” modes.
5. Press Enter to save any change.
6. Press Exit to return to the operation display.
When a display is adjusted to “listen only mode”
the following message flashes three times
during the start-up routine: “T
HE DISPLAY IS IN
LISTEN ONLY MODE
”.
2.16b Remote monitoring
The remote-monitor mode enables one GS820 (the
supervisor display) to monitor another GS820 (the
operator display) from a remote location.
The supervisor display is synchronized with the
operator display configuration and listens directly to
the sensors in the sensor list. Furthermore, with the
option "sync operating page" the supervisor display
can be synchronized to the exact page shown by the
operator display when not in menu mode.
Set-up
1. Set the display mode to "remote monitor" on
line 1 of menu 4I1) N
ETWORK CONTROL.
2. Set the ID of the operator display to be
monitored on line 2.
3. Set the sync operating page option as required
on line 3.
When communication has been established
and the supervisor display configuration has
been synchronized the message "Remote
monitor of id Gxxxxx" appears on the top line
of the supervisor display.
Operation
The supervisor display is not synchronized
when the operator display is in the menu mode.
When the operator display is returned from
menu to operating mode it synchronizes the
supervisor display with any changes that have
been made to the system configuration.
The supervisor display records all normal data
logger events in parallel with the operator
display, except during synchronization or when
it is turned off.
When remote monitoring is turned off, the entire
system configuration is cleared from the
supervisor display and all parameters revert to
their default values.
Restrictions
Both the supervisor and operator displays must
have exactly the same firmware and capacity chart
(if applicable). Remote monitoring uses the
standard
LSI
LSI radio protocol; it is subject to the
same limitations. A clear and direct line of sight
may be required between the remote monitor and
both the operator display and the system sensors.
Supervisor display system parameters cannot
be adjusted when in remote monitor mode.
An operator display can only be monitored by
one supervisor display at a time.
2.16c Repeater
Communication between a GS820 and a
programmed sensor can be routed through a different
programmed sensor (repeater). This can be done
either to extend the range of the network or to assist
communication around a large radio obstacle. The
battery life of the sensor repeated (source) will be
reduced by about a year*. The battery life of the
sensor repeater will be reduced to 35 days**. This
function should not be used where it is not required.
IMPORTANT! Sensors can only have one
network controller at a time. To receive
communication from a sensor without taking
control of that sensor a display must first be
programmed in “listening mode”.
Note: To regain network control of programmed
sensors adjust the GS820 to “
NETWORK CONTROLLER”,
shut the display off, and then start it again.
!
!
IMPORTANT! Do not set a dedicated
system display to remote monitoring mode.
The entire system configuration will be lost
including the sensor list and radius parameters.
