5.1.2 Host Establishes Communications
Assumption: Equipment’s Communication state is either “Enabled/Not Communicating” or
“Enabled/Communicating”.
Table 5-2 SECS Messages Host Establishes Communications
Step SECS Message Description
1. H -> E S1F13 W Host sends Establish Communications Request.
2. H <- E S1F14 The Equipment responds with Establish Communications
Acknowledge, with COMMACK set to zero. After this message
is successfully sent, communications is established. If the
current communication state is “Not Communicating”, the
Equipment changes its communication state to
“Communicating”. If the state is “Communicating”, no change in
communication state occurs. In either case, subsequently
received messages are processed normally.
5.1.3 Simultaneous Establish Communications
Assumption: Equipment’s Communication state is “Enabled/Not Communicating”.
Table 5-3 SECS Messages Simultaneous Establish Communications
Step SECS Message Description
1. H <- E S1F13 W Equipment sends Establish Communications Request.
2. H -> E S1F13 W Host sends Establish Communications Request.
3. H <- E S1F14 The Equipment responds with Establish Communications
Acknowledge, with COMMACK set to zero. After this message
is successfully sent, communications is established. The
Equipment changes its communication state to Communicating.
4. H -> E S1F14 The Host responds with Establish Communications
Acknowledge, with COMMACK set to zero. This step could
occur before Step 3, in which case communications would be
established at this step.
