This section describes primary SECS messages sent by the Equipment, and the
associated reply messages from the Host.
In the column headed "Notes", those messages marked with "E" are extensions beyond
GEM. Those messages marked with "N" are provided for non-GEM or older GEM
compatibility.

This section describes the working characteristics of the SIPLACE. It is divided into
sections, and each of these sections describe a particular aspect of the SIPLACE's
operating characteristics.

The SIPLACE represents the current state of its SECS link using a Communication Finite
State Machine diagram. The purpose is to make clear how this link is initiated and
terminated.

The following transitions can occur. Transitions of the Communication Finite State
Machine diagram do not cause the SIPLACE to signal any Collection Event ID (CEID), nor
to send Event Reports to the Host.
# From Trigger To Description
1 Unknown Power-Up Conditional Equipment will initialize
itself to either the
Disabled or Enabled
state, depending on the
configuration of the EC
INITCOMMSTATE (VID
1002002).
2 Disabled Button

3 Enabled Button
„Disconnect“ is
pressed in the

Disabled Communications are
abruptly terminated. Any
