ON RTS is always ON.
This parameter is for old boards that do not react fast enough to RTS.
Minimum number of flags between HDLC frames <0-15> [0]:
Number of HDLC flags between frame transmissions. For old OEM equipment, specify a large
value.
Minimum TX time <0-2000> mSec [1000)]:
Minimum transmission time. If the actual data transmission takes less than the specified value,
the unit will continue to transmit until this time elapses. Smartzone trunked systems work
more efficiently with a minimum TX time of 1000 mSec. Specify 0 to ignore this parameter.
Time before long warm-up <0-3000> mSec [1600]:
In Smartzone trunked systems, this parameter specifies on channel/free channel condition
which, if exceeded, requires a longer warm-up. Specify 0 to ignore this parameter.
Long warm-up <0-2500> mSec [1000)]:
If a positive value was specified in the previous parameter, specify here the long warm-up
time. 1000 is advisable in Smartzone.
Time resolution in control channel <50-1000> mSec [50]:
In a trunked system, this parameter specifies the size of a time slot when the radio is on the
control channel.
First warm-up delay <10-2500> [350]:
This field defines the delay (in msec) from the moment that PTT has been pressed until data
transmission starts on the first time in a session.
Tx Hold off time <0-10000> [0]:
The minimum interval between two consecutive transmissions of data (not relevant for
acknowledgment messages).
Consequent warm-up delay <10-2500> mSec [350]:
This field defines the delay (in msec) from the moment that PTT has been pressed until data
transmission starts, on subsequent sessions (after the first; see previous parameter). The value
should be greater than the First Warm-up Delay, because the first time the Trunking system
perfoms part of the warm-up by itself.
Channel monitor time resolution <10-2500> mSec [200]:
Defines the interval from the moment PTT has been pressed in an RTU until the other RTUs
sense it. This interval depends on the type of the radio used – the quicker the channel monitor's
response, the shorter this interval. The RTU uses this parameter to prevent collisions on the
channel when several RTUs have messages to transmit by contention.
This interval is used (automatically) as follows: each RTU is assigned a priority level as a
function of the data message it wants to transmit (new data, acknowledgment, retry, etc.) and
in some cases, as a function of its address. When the RTU wants to transmit that message, it
first checks whether the communications channel is free or not. If the channel is free, the RTU
