Stations per Poll Time
Note
The parameters Poll Time and Stations per Poll Time appear
in all communications modes except for Wire line.
This parameter is found on all System Configuration Menus except for Wire Line
communications mode, where it is fixed at zero. This parameter holds the number of
stations polled during each polling cycle. If it is set to zero then all stations are polled
during every polling cycle. If this parameter is greater than the number of remote stations
being polled then it defaults to the total number of remote stations. (It is usually
recommended that this parameter be set to zero (0).)
Note
If a poll cycle has started, all stations will be polled before the M26
starts checking the status of alerted stations. Even though the
actual alert time will NOT change, longer than expected delays in
“PA Ready” are possible, especially with a longer key-up delay
setting.
To minimize “PA Ready” latency during a poll cycle, we
recommend that the “Stations Per Poll Time” be set to 1, and the
“Poll Time” be set to time required to compete a full poll cycle
divided by the number of M6 stations. For example:
Poll Time - 0:06:00.00 (Hr:Min:Sec:Hun) Ö (6 minutes are set)
Stations Per Poll - 1 (0 = All) Ö (one station per poll)
This example shows settings that allow 10 stations to be Polled
within a one hour interval at a rate of one station every 6 minutes.
With a 1 second key-up delay time programmed, the “PA Ready”
latency, due to a poll cycle, will only be 2 seconds longer during
the poll cycle (i.e. two seconds per station polled longer).
Number of Positions
This parameter is found in the System Configuration Menu. It holds the total number of
Model 26 positions (connected together at the CHAIN port). This parameter is important
in optimizing system performance because it limits the primary Model 26 to polling only
existing secondary Model 26 units. The value of this parameter can range between 1 and
15.
Keyup Delay
This parameter is found in the System Configuration Menu. This parameter holds the
delay time, in seconds, from PTT activation to the start of data transmission in the
conventional mode. In trunking mode, it is the delay time from receiving the channel
grant to the start of data transmission. This delay allows the radio path to stabilize before
data is sent. This parameter accepts a value between 0.00 and 59.99 seconds. Since the
