The Communicator interfaces to the SCW through a keyed 16 pin Ribbon cable. See Table 6 .
The key prevents incorrect connection of the ribbon cable connector to the SCW and Commu-
nicator. The pinout for the Ribbon cable is provided in the Table below:

Establishing a communication channel between the Communicator and the SCW is critical to
ensuring the desired operation of the two units. The following steps must be completed during
the on-site installation. Program the following to ensure that the Communicator and the panel
will work together as intended.
Initial Programming of Communicator and SCW
1. Enter [*][8][Installer Code] [Section Number] for panel programming. Record any values that

Initial Programming of Communicator and SCW
1. Enter [*][8][Installer Code] [Section Number] for panel programming. Record any values that
are modified from their default, in the appropriate Programming Worksheets.
NOTE: When programming Toggle Options, the toggle is ON when the number is displayed and
OFF when the number is not dis played. (e.g., [1 - - - 5 - - - ], Toggle Options 1 and 5 are ON, all
others are OFF).

2. Panel Section [167] Cellular/Ethernet Interface Communications ‘Wait for ACK’: Default
value is: 060 seconds.
3. When the communicator is installed with the SCW panel, 4 telephone numbers are
available to backup one another. You can set up these 4 telephone numbers to perform in
one of two ways: Backup dialling or Alternate dialling.
one of two ways: Backup dialling or Alternate dialling.
a. Backup dialling: each of the 4 telephone numbers will make 5 dialling attempts in turn,
before an FTC trouble is displayed on the keypad.
b. Alternate dialling: each telephone number makes 1 dialling attempt before moving on to
the next number, cycling through each of the 4 numbers for a total of 5 times each. If all 4
numbers fail the 5 attempts, an FTC trouble is displayed on the keypad.
4. Panel Sections [301], [302], [303], and [305] can be configured as Primary
communication paths.
a. Panel Sections [302], [303], and [305] may also be configured for backup or redundant
communications by using Panel Section(s) [383] or [351] - [376]. Refer to the SCW
panel Installation Manual for more information.
If a valid telephone number is programmed, communications will use Public Switched Tele-
phone Network (PSTN). Entering a 4 digit hexadecimal value for a telephone number will
change the call routing to the Communicator, as determined by the number programmed:
DCAAF:Internal (All Receivers). Signals will be routed depending on Section [851] [006] pro-
gramming.
DCBBF:Ethernet Receiver 1 (Primary). (Not available for LE2077).
DCCCF:Ethernet Receiver 2 (Backup). (Not available for LE2077).
DCDDF:Cellular Receiver 1 (Primary).
DCEEF:Cellular Receiver 2 (Backup).
