The baud rate list provides selection of the serial port asynchronous baud rate.
The serial port 2 baud rate is fixed at 9600 baud.
The number of data bits for serial port 2 is fixed at eight.
The parity of serial port 2 is fixed at no parity.
Selection Description
Data Activation
This mode uses a character timer to frame the
transmit data into bursts. The TS4000 burst begins
when one character (non-control string) is received.
The transmit burst is completed when the transmit
data line is idle (no data) for the number of
character periods defined by the data activation
timeout control.

The transmit burst is completed when the transmit

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

Parity control and 1 if even or odd is selected. The

This sets the minimum amount of time (in character periods) that the receive
data (RXD) line will be idle (inactive) between received bursts of data. If this
value is set to zero, the receive data line may remain active continuously when
multiple bursts of receive data are transferred to the host.
If the DCD line option is set for the Active when Sending Receive Data to the
User then the DCD line will also be inactive during the receive data line idle
times.
DCD is active when the TS4000 detects a signal on the radio channel. This
mode can be used to remote the receive light.
