Spread Spectrum Wireless Data Transceiver User Manual
ATD_
This command does not work if
Entry to Call
is set to ‘All’ or if the Call Book is empty. If
Entry to
Call
is set to ‘All’, the transceiver which received the
ATD_
command will try to communicate with any
Slave in the network that is listening, regardless of the serial number specified in the
ATD_
command.
The line to which
Entry to Call
is referring to, should have:
•
A non-zero serial number entry in the main column and no entries in the Repeaters columns if
there are no Repeaters to be used
or
•
A non-zero serial number entry in the main column followed by valid entry(s) in the Repeaters
column(s) of one or more Repeaters to be used.
ATXS
Sending this command will force the transceiver to enter Setup mode. While in Setup mode, the
transceiver’s RS232 baud rate will be set as what was programmed in the Baud Rate Menu rather than
the typical 19200 bits/s.

Point-to-Point Slave/Master Switchable mode accepts the command ATD####### where ####### is any
transceiver serial number. Upon receipt of this command the transceiver calls the transceiver, even if the
number is not in the sending transceiver’s Call Book.
The Slave security may be disabled so that a transceiver operating as a Slave in Modes 1, 4, or 6, will
connect to any transceiver calling it regardless of whether or not the calling transceiver is in the Slave’s
Call Book. This feature is necessary when there are more than 10 transceivers that may call into a Slave.

Calling a transceiver through one or two Repeaters
In conjunction with the ATD command, the transceiver may be instructed to use the Repeater(s) specified
in the Call Book. This means it is possible to call an unlimited number of Slaves through script files in
Point-to-Point Slave/Master Switchable operation mode and have up to 10 different Repeater
combinations. Before calling a transceiver through one or two Repeaters, the Repeaters to be used must
first be set up in the Call Book. This is done by setting up a number to call through the Repeater(s) which
are to be used.
