Intercom Interface: C2N-IIF

Purpose

The purpose of this addendum is to provide additional information not supplied with
the original C2N-IIF Operations & Installation Guide (Doc. 6235). Specifically, this
addendum provides additional information with regard to:

• The SIMPL Windows device symbol that appears on page 28.

• Signal definitions that appear on pages 29 through 31.

Revised SIMPL Windows Device Symbol

Due to changes in the C2N-IIF firmware (version 1.35 or later), the SIMPL
Windows device symbol has been changed. Since muting can be accomplished by
using other signals in the device symbol, the MuteAudio digital input signal has
been removed to simplify programming. Instructions for programming a Mute
function are now provided in the revised signal definitions found on page 3 of this
document.

The following diagram shows the new device symbol.

New Signal Definitions

Many of the signal descriptions have been rewritten to better explain the
functionality of the C2N-IIF and reflect the features found in C2N-IIF firmware
version 1.35 or later. Refer to the following tables for the latest signal descriptions.

C2N-IIF Digital Input Signal Descriptions

INPUT DESCRIPTION

Output1_On/Off
through
Output8_On/Off

Activates the corresponding output (electronic
switch closure to ground) for as long as the
input is high. Turns off the output when the
signal is low. In the Essex and Discrete modes,
all eight outputs are available. In the Matrix
mode, only outputs 1 through 4 are available,
while outputs 5 through 8 are reserved to
enable four-by-four matrix switching.

EssexBacklight When high, the Essex keypad (if installed)

backlight is activated for as long as the signal
remains high (Essex mode only).

AudioOutputEn Enables audio to be routed from the line level

source to the speaker output, for as long as the
signal remains high. When low, cuts off the
audio path.

In order to hear the audio input through the
speaker output: 1) a WAV file must not be
playing (triggering a WAV file will override the
audio input); 2) the audio volume level must be
above 0%; and 3) The signal AudioOutputEn
must be high.

Mute Functions:

To mute the audio input, AudioOutputEn
should be set to low.

To mute WAV file playback, CancelWAV

should be pulsed high.

To mute all audio, AudioOutputEn

should be set to low and CancelWAV
should be pulsed high.

NOTE: The signal definition for EssexBacklight has not been changed
