8.8 Common Functions for Data Communications
8.8 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.
• Number of Retries
• Transmit Busy Wait Time
• Maximum ACK Wait Time
• GTC Count
• ACK Delay Time
• Transmit Delay Time (Receive Capture)
• Data Transmit Modulation Delay Time
• Message Display Type
• Random Access (Contention)
• Preamble Length
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.
Configuration using KPG-111D/ DN
Configuring the Number of Retries (
Transmit Busy Wait Time
The transceiver confirms that the communication channel is available before sending data and then starts sending data
when the channel is available. Transmit Busy Wait Time is the duration to wait for the communication channel to become
available.
A transmission is canceled when the channel is busy and the Transmit Busy Wait Time elapses.
The default configuration is normally used.
Configuration using KPG-111D/ DN
Configuring the Transmit Busy Wait Time (
Maximum ACK Wait Time
Maximum ACK Wait Time is the length of time that the transceiver stands by to receive the acknowledgment after the
transceiver sends data. If the transceiver does not receive the acknowledgment within the time configured for Maximum
ACK Wait Time, the transceiver resends data.
The default configuration is normally used.
Note
• This period can also be used for waiting on a data channel, after migrating to the data channel using the GTC.
• A Long Data Message transmits data divided over multiple times. The receiving transceiver stands by to receive the next data for the
time configured for Maximum ACK Wait Time after receiving the previous data. The transceiver exits Long Data Message Receive
Mode if the transceiver does not receive any data during the period.
