22.3.3.2 Radio Parameters
Sync Delay
Important: This parameter should not be changed from its factory setting without a clear
understanding of the timing of the radio protocol.
Sync Delay specifies the delay between the time of the base station transmission and the first
response window, measured in character times. The value assigned to this parameter must
be compatible with other base stations and mobile computers in the system. The RA1001A
radio is available in either two level or four level modulation, providing baud rates of 4800
bps and 9600 bps, or 9600 bps and 19200 bps, respectively.
The default setting for a two level modulation narrow band radio, operating at 9600 baud,
is
23 .
The default setting for a four level modulation narrow band radio, operating at 19200 baud,
is
31 .
Remote Txon
Remote Txon accommodates the turn-on time of the radio in mobile computers (remotes). It
specifies the number of fill characters sent to the radio before real data is output. Since this
parameter is based on character times, the number is dependent on the radio link baud rate.
The value assigned to the
Remote Txon parameter must be consistent across all mobile com-
puters and base station equipment. The allowable value range is 3 to 60 .
Important: This parameter should not be changed from its factory setting without an
understanding of the timing of the radio protocol.
Active Channel
This parameter determines the operating radio channel of the 9160 G2. This makes the
channel available for channel searching by the mobile computers. The channel selected must
be one of those that have been configured with frequencies, as indicated on the
Narrow
