Testing Signal Strength Between Units
There are three methods to test if there is sufficient signal strength between units.
1) Link Test (All Nodes)
Go to the
LINK TEST
screen and press Enter. If there is another Node within
range of the unit, the word
RECEIVING
will flash on the bottom of the display
each time the LR900 transmits.
Note: The LR900 does not display which Node has responded, nor the signal
strength, only that another Node can hear it.
2) Range Test (Specific Node)
Go to the
RANGE TEST
screen within the
ADJUSTMENTS
menu. With each
press of the Enter button, the LR900 will send a request to a single node in the
system. If the Node show on the screen receives the signal, it responds with
the strength of the signal IT received. The results are displayed on the screen
as a percentage (ie. 100% is good, 40% marginal). Perform the test 10 times
and average the results. Individual results vary depending on local
interference.
To change which Node will receive the request, press the
DOWN
button when
in the
RANGE TEST
screen. The screen will change to
“Editing”
. Use the
keypad buttons to change the destination address to the new desired Node
number and then press the
ENTER
button to make the change.
Advanced Features and Information
Zones
LR900 units can be sub-grouped to only accept a command if they are within this subgroup.
All other nodes will repeat the signal, but they will ignore the command because they are not
in the subgroup.
(This feature requires the use of the LR900 computer program)
Roll Call
Roll Call is used to find other Nodes on the system with the same System ID, Channel
number and Encryption Code. Press the ENTER button to begin a Roll Call. The first units to
respond within 10 seconds are displayed on the screen. The information displayed for each
Node is the Unit ID followed by the signal strength for that unit.
RF Beacon
RF beaconing is used in systems with Master Internet Nodes. When selected, a Node will
transmit at a selected interval that it is alive, its battery voltage, external power voltage, input
and output status.
