8.8 Common Functions for Data Communications
Data Transmit Modulation Delay Time
Data Transmit Modulation Delay Time is the duration from when the transceiver starts transmitting until the transceiver
starts being modulated by the data frame.
Data Transmit Modulation Delay Time is used to allow the transmitted radio signal to stabilize before applying data.
However, it may be difficult to establish data communications when the transmit and receive frequencies are widely
separated or the transceiver is always used in extremely cold areas. In such cases, Data Transmit Modulation Delay Time
must be extended in order to improve the reliability of data communications.
The default configuration is normally used.
Configuration using KPG-111D/ DN

Received Message Display Type (Message Display Type)
Message Display Type can be used to display a message on the main display type when the transceiver receives the
Status Message or Short Message.
Configuration
"STM/SDM" appears on the main display when the transceiver receives a Status Message or Short
Fixed
Message. A message is scrolled on the main display if the message is longer than 15 characters.
"STM/SDM" appears for 3 sec and Unit ID appears for 2 sec on the main display alternately upon receipt of
Alternate
a Status Message or Short Message.
Note
• The previous display appears again by pressing a key while the received message is displayed.
• This function is unavailable for NX-200S/ NX-300S.

Random Access (Contention)
Random Access allows the transceiver to randomize the transmission start time for each transceiver to send data when
the channel becomes available.
If a large number of transceivers begin transmitting immediately after the channel becomes available, transmission
contention may occur. This function prevents this contention.
Note
The length of time for Random Access varies depending on the configuration for the Channel Spacing (Narrow or Very Narrow).
