Note:

It is important that the Call Book slots (0-9) are filled sequentially beginning with 

0

,

the first slot in the book. ID numbers do not need to be entered in numerical order, however,
there must not be any 000-0000 numbers in the middle of the lists of good ID numbers.  The
reason for this is that when a master is instructed to Call All available slaves it will call all
slaves listed until it reaches the first number of 000-0000.  If a valid ID number is entered
after the all zero number it will not be recognized as a valid number to call by the master.

Programming The Call Book in Multipoint systems

In a Multipoint system the slaves and repeaters are not listed in the master’s Call Book.
When

 

establishing such a system, it is necessary only to have the master’s ID number in each

slave’s and repeater’s Call Book, and to have each repeater’s ID number in the Call Book
of each slave which may potentially communicate through it.

The following example shows the Call Books of  a Multipoint system comprised of a master,
repeater, and slave in which the slave can communicate either

 

through the repeater or

directly to the master:

Multipoint master Call Book (Unit ID Number 555-0001)

Entry

Number

Repeater 1

Repeater 2

(0)

000-0000

(1)

000-0000

No ID number entries are necessary in the master’s Call Book.
The master’s Call Book may be programmed to call any entry.

Multipoint repeater Call Book (unit ID Number 555-0002)

Entry

Number

Repeater 1

Repeater 2

(0)

555-0001

(1)

000-0000

Multipoint slave Call Book (Unit ID Number 555-0003)

Entry

Number

Repeater 1

Repeater 2

(0)

555-0001

(1)

555-0002

(2)

000-0000

At times it may be desirable to force a slave to go through a specific Multipoint repeater.
If this is the case, that slave’s Call Book should contain only the ID number for the repeater
in the upper left hand corner.

Note:

 If the network ID option is used no entries are needed for any of the transceivers in

a Multipoint system.
