Select From-Start-of-Transmission Timer
Allows controller to
“disconnect” the DTMF decoder from a receiver if
it appears no DTMF command will be entered during a transmission.
·
The DTMF decoder is free to find another source of DTMF commands if the
current user does not enter a digit within 5 seconds from start of
transmission (See the
Select DTMF Priority/Scan
command).
·
Reduces DTMF
“falsing”, since the DTMF decoder only listens during the
beginning of the transmission.
·
Enter one digit, 0 for OFF (disabled), 1 for ON (enabled).

Default Condition:
From-Start-of-Transmission Timer is OFF (disabled) for all
receivers.
Examples:
If this feature is disabled, the receiver will feed the DTMF decoder for the
duration of the transmission (subject to its priority. (See the
Select DTMF
Priority/Scan
command).
If this feature is enabled, the receiver will feed the DTMF decoder for the first 5
seconds of the transmission (subject to its priority). If a user wishes to enter a
command and has already transmitted more than 5 seconds, he must unkey
and re-key before entering the command. Once a DTMF digit is entered, the
receiver will continue to feed the DTMF decoder for the remainder of the
transmission.
