Call Book
Use of the Call Book is required in Point-to-Point networks. While the call book is an option in Point-to-
MultiPoint networks, the Network ID feature is strongly recommended in most applications.
The instructions provided in this section are for Point-to-Point mode only. Use of the Call Book for
MultiPoint networks is explained later in this chapter.
Using the Call Book offers both security and flexibility in determining how FreeWave transceivers
communicate with each other.
Three settings must be made for two FreeWave transceivers to communicate in Point-to-Point mode:
1. The Master’s serial number must be listed in the Slave's Call Book or Slave Security is turned off
in the Slave.
2. The Slave’s serial number must be listed in the Master's Call Book.
3. The Master must be programmed to call the Slave.
The Call Book allows users to incorporate up to 10 FreeWave transceivers, designate 1 to 4 Repeaters to
be used with each transceiver, and designate which Slave the Master will call. To set the Entry to Call
option, enter C at the prompt, followed by the menu number corresponding to that Slave. To call any
available Slave in the list, enter C then enter A to direct the Master to Call All.
Note: To call a Slave through one or more Repeaters, that Slave must be called individually. With Call
All selected, the Master will not connect with any Slaves through Repeaters. The Master calls
every Slave in the list and will connect with the first Slave that responds. When calling through a
Repeater, the Master must first call that Repeater and establish a communication link with it prior
to making contact with the Slave.

2. Select the appropriate number to edit by typing the associated line number at the cursor.
