Main Menu Option (2): Edit Call Book

If the PLR580 system is only two (2) units, one Master and one Remote, then either Point-to-Point or Multipoint modes can

be used. If the system has more than one Remote, then Point-to-Multipoint mode must be used. Use of the Call Book for

multipoint systems is explained later in this chapter.

The Call Book is an innovative feature in the PLR580 that offers both security and flexibility in use. The Call Book

accomplishes this by allowing the user to determine with which other PLR580s a given radio modem will communicate,

based on the Call Book numbers for both the master and remote. The radio modem’s Call Book number is encoded in the

microprocessor and identified on a label on the modem. The instructions provided in this section are for point-to-point mode

only. Use of the Call Book for multipoint systems is explained later in this chapter. For two PLR580 radio modems to

communicate in point-to-point mode, three events must occur:

1. The call book number for the master must be listed in the Remote’s Call Book.

2. The call book number for the remote must be listed in the master’s Call Book.

3. The master must be programmed to call the remote.

As shown in figure 13, the Call Book allows users to set up a list of up to 10 PLR580s to communicate with. Designate up to

2 repeaters to be used in communicating with a given radio modem, and tell the master which remote to call. To direct the

master to call a remote, the Remote must be in the Call Book Menu. A specific remote may be called by entering (C) at the

prompt, followed by the menu number corresponding to that remote. To call any available remote in the list, the user should

enter C and then A (for All).

Note: To call a remote through one or two repeaters, you must call that remote directly (as opposed to using the

Call All option). When Call All is selected the master is not able to connect with any remotes through repeaters. This

is because the master calls every remote in the list when instructed to call all and will connect with the first remote

to respond. When calling through a repeater, the master must first call that repeater and establish a communications

link with it prior to making contact with the remote.
