Gtc Count; Number Of Retries; Transmit Busy Wait Time; Maximum Ack Wait Time - Kenwood TK-3180 Function Reference

22.9.9 GTC Count

This function allows you to configure the number of times
to transmit the GTC.
GTC (Go To Channel) is a message that allows the
transmitting party to take the receiving party to the data
channel.
The caller's transceiver transmits the GTC and moves to
the data channel when the Status/ Short/Long Message
on the Data Channel is configured. The receiving party's
transceiver automatically moves to the data channel and
waits for the data.
You can configure the GTC to be sent and the number of
times to send it using KPG-89D. A user can normally use
the default configuration.
Note:
" The receiving party's transceiver waits for receiving the Status/
Short/Long Message after it moves to the data channel. The
transceiver returns to the voice channel when no data is
received during the Maximum Ack Wait Time.
" The caller's transceiver sends the Status/Short/Long Message
and waits to receive the ACK after it moves to the data channel.
The transceiver returns to the voice channel when it does not
receive the ACK for the Maximum Ack Wait Time.

22.9.10 Number of Retries

If the transceiver does not receive the ACK for the
Maximum ACK Wait Time, it resends data. You can
configure the Number of Retries. Decrease the number
when communication conditions are good and increase
the number when the communication conditions are not.
You can configure the Number of Retries using the KPG-
89D.

22.9.11 Transmit Busy Wait Time

The TX Busy Wait Time is the period the transceiver
withholds the FleetSync data transmission when the line
is Busy. The transmission is canceled when the line is
busy even if the Transmit Busy Wait Time expires.
You can configure the Transmit Busy Wait Time using
KPG-89D.

22.9.12 Maximum ACK Wait Time

The Maximum ACK Wait Time is the duration for the
transceiver to wait for receipt of the ACK from the
receiving party after transmitting data. If the transceiver
does not receive the ACK after the Maximum ACK Wait
Time, it resends data.
You can configure the Maximum ACK Wait Time using
KPG-89D. We recommend using the default
configuration.
Note:
" This period is applied to the wait time for receiving data after
moving to the data channel using the GTC function.
" The Long Data Message is sent several times. The receiving
party's transceiver waits the next data during the Maximum ACK
Wait Time. The transceiver exits the Long Data Message
Reception Mode when it does not receive any data during the
period.

Wait Time.)

22.9.13 ACK Delay Time

The ACK Delay Time is the delay time between time the
transceiver receives FleetSync and the time when it
transmits the ACK.
This period must be shorter than Maximum ACK Wait
Time configured in the caller's transceiver. In addition,
this period must be shorter than the Hang Time of the
repeater when using the ARQ function in a Trunking
system. (Refer to 17.7 ARQ Mode.)
You can configure the ACK Delay Time using KPG-89D.
We recommend using the default configuration.

The Transmit Delay Time is the transmit period of the
unmodulated carrier prior to the data transmission.
The transmitting transceiver performs the unmodulated
transmission and the receiving transceiver stops
scanning to receive the data. With this function, a user
