12.5 Common Functions for Data Communications
12.5 Common Functions for Data Communications
The following functions are used in common for data communications such as Status Call or Short Data Call, Long Data
Call data transmission.
• GTC Count
• Number of Retries
• Transmit Busy Wait Time
• Maximum ACK Wait Time
• ACK Delay Time
• Transmit Delay Time (Receive Capture)
• Data Transmit Modulation Delay Time
• Data Preamble Extension Time
• Message Display Type
• Random Access (Contention)
GTC Count
GTC Count is the number of times to transmit the GTC using the transmitting transceiver.
GTC (Go To Channel) is a message that allows the transmitting transceiver to induce the receiving transceiver to the data
channel.
The transmitting transceiver will migrate to the data channel after transmitting the GTC if the Status, Short or Long
Message on Data Zone-CH/GID is configured. When the receiving transceiver receives the GTC, it automatically migrates
to the data channel and stands by to receive the data.
Default value for the number of times is normally used.
Note
• The receiving transceiver waits to receive the Status, Short or Long Message after the receiving transceiver migrates to the data
channel. The transceiver restores the voice channel if the transceiver does not receive the acknowledgment within the time configured
for Maximum ACK Wait Time.
• The transmitting transceiver sends the Status, Short, or Long Message and waits to receive the acknowledgment after the transmitting
transceiver migrates to the data channel. The transceiver restores the voice channel if the transceiver does not receive the
acknowledgment within the time configured for Maximum ACK Wait Time.
Configuration using KPG-111D/ DN
Configuring the GTC Count (
Number of Retries
The transceiver resends data if the transceiver does not receive the acknowledgment even after the time configured for
Maximum ACK Wait Time elapses. Number of Retries is the number of times for the transceiver to resend data. A smaller
number can be configured if there is good communicating conditions, and a larger number can be configured if there are
inferior communicating conditions.
