Description
S144
Sleep Time
This register applies only to Remote modems and is only effective when S143>0.
Defines sleep duration for up to approximately 18 hours.
Two conditions will awaken a Remote:
1. Sleep duration time has expired, or
2. Incoming data on local data port.
When a sniff mode is selected (S143), the modem will start its sniff cycle when
the Sleep Time expires or will wake up completely when there is data on its local
data port.
Values:
seconds
2–65535
60
S145
Wake Time
Applies only to Remote modems and effective only when S143>0.
This register determines how long a modem will stay awake after the local data
port and radio links become idle.
When the modem is idle for the amount of time specified in S145, it will go to
sleep; it will go to sleep immediately if the “upstream” unit is offline or goes into
sleep/sniff mode.
Values:
seconds
0–65535
10
NOTE: The most effective way to put an entire network into sleep/sniff mode is by
turning off, or putting into command mode, the Master modem.
S149
LED Brightness
This is a power saving feature that controls the current available to LEDs so they
operate with 0% (off) to 100% available brightness.
We recommend setting S149 to 100 for testing in a shop environment, and then
reducing the value as required when deploying in the field where power
consumption is a factor.
Values:
percent (%)
0–100
100
S150
Sync Mode
This setting applies only to the Master modem. S150 dictates which sync mode
the Master will use when it initially goes online. Quick sync mode results in the
Master hopping very quickly, which will enable a downstream unit to become
synchronized faster.
Values:
0 normal sync
1 quick sync mode, wait for acknowledgement
2 quick sync mode, wait for timeout
