This string can be a maximum of 10 characters long. All characters are either
numbers or letters. The prefix “DE” (from) is added to the beginning of the transmit-

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.
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 terminals in the system.
The TRX7370 radio is available in either two level or four level modulation, provid-
ing 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.
19200 baud, is 31.
Remote Txon
Remote Txon accommodates the turn on time of the radio in terminals (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.
