TS4000 Radio Modem User’s Manual Serial Port 15
Selection Description
Data Activation Timeout
(Timeout Time)
This control sets the number of character periods
of idle required on the serial port's transmit data
line to declare the end of a transmit burst.
Char Period = Char Length / Baud Rate
Where: Char Length = Data Bits + Parity + 2
Data Bits is the value selected from the Data Bits
control. Parity is 0 if none is selected from the
Parity control and 1 if even or odd is selected. The
2 added to the accounts for the start and stop bits
of an asynchronous character. Baud Rate is the
value selected from the baud rate list.
When this is active RTS is used to control sleep mode. When RTS is inactive,
the modem will enter sleep mode until RTS is activated.
This option only has effect only in transparent (non-packet) mode. In packet
mode the TS4000 always waits for a complete burst before beginning
transmission.
Selection Description
Disabled The modem begins transmitting as soon as it
receives the first non-control character of a transmit
burst.

before it begins transmitting.
