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 no

Repeaters to be used

• 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.

ALLING A TRANSCEIVER THAT IS NOT LISTED IN THE CALL BOOK

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 defined 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 more than 10 transceivers may call into a Slave. For more

information, see Slave Security.

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 line in the Call Book to call through the

Repeater(s) which are to be used.

Note: All serial Repeaters must be entered in the Call Book with respect to the Master. For example,

Repeater 1 will be the first radio the Master communicates with. Repeater 2 will be the second,

and so on.
