Local and Sender RSSI (Received Signal Strength Indicator) Values
In Active Mode, allow a few minutes for Local and Sender dBm (decibel
milliwatt) values to settle. See Figure 98.
Local (Tx) value ranges between -100 dBm and -10 dBm.
Sender (Rx) value ranges between -100 dBm and -10 dBm.
Note:
Sender (Rx) values closer to -10 dBm are preferred.
If either value settles between -80 dBm and
-100 dBm, this indicates weak, unreliable signal.
Refer to following sections for options to resolve this problem:
Transmission (Tx) Power
Reception (Rx) Sensitivity
NOTICE
LCD backlight does not shut off in Site Survey Mode. To prevent
draining the battery, exit this menu when finished.
Troubleshooting
A network requires just one radio configured as a Transmitter, with all others
configured as Receivers.
To function, each radio within a network must be configured with the same
8-digit Binding Code and the same Frequency Hopping Channel.
These values can be quickly viewed in the
MAIN MENU > Radio Status
menu.
Binding Code and Frequency Hopping Channel values are typically pre-
set at factory: verification of these values is explained in the section
Radio
Status >Radio Network Table
.
Avoid Co-locating Radios
Do not install or test radios within six feet of each other. If the Transmitter
radio is located too closely to any Receiver radio, communication
between all radios may be interrupted.
Automatically Joining the Network
Assuming the Binding Code and Frequency Hopping Channel values
match on all radios in the network, Receiver radios automatically join the
network within ten minutes of applying power to all radios.
