1 DMR CONVENTIONAL SYSTEM
1.9 Common Functions for Data Communications
Preamble Length
Preamble Length is the function to extend the duration for sending a preamble when the DMR frame is sent.
Extending the time for sending a preamble at the beginning of transmission makes the receiving transceiver easier to receive
a call and reduces missing of the beginning of the audio during the scan.
The extended time of a preamble is determined by using the following equation.
Time [sec] = 60 ms x Configuration value for Preamble Length

1.10 Sending and Receiving a Status Message (Status Call)
Status Call is a simple messaging system that allows a user to send and receive a status (Status Message). Since the
message is replaced by status, communications can take place quickly and communication traffic can be reduced.
The following methods are available to send a Status Message.
Transmission
Methods
The transceiver enters Status Mode by a user pressing a PF key or a key on the keypad, and then
Status Mode
the transceiver will send a Status Message. (Refer to
Pressing one of the "Call 1" to "Call 6" keys allocated to the PF keys of the transceiver causes the
transceiver to send the preconfigured Status Message.
For Mobile, the Status Message preconfigured in the transceiver is sent when any of the "Call 1"
to "Call 6" ports allocated to the AUX Input port becomes active.
Call key
"Call 1" to "Call 6" can be assigned to the PF keys or AUX Input ports by using KPG-D1/ D1N, and
the Status Message corresponding to each key can be selected from the Status List in DMR.
In this case, a Status Message is always sent to the preconfigured Base ID.
The transceiver sends the Status Message configured in the transceiver when the transceiver is

In this case, a Status Message is always sent to the preconfigured Base ID.
AUX Input Status The specified Status Message is sent when the AUX Input port goes high level to low level or goes
Message (Mobile Only) low level to high level. (Refer to
The transceiver will send a Status Message when the transceiver receives a PC command from
the communication port. To use a PC command, "Data" or "Data + GPS Data Output" needs to
