ISM4 INSTALLATION & PROGRAMMING MANUAL
27
OPERATING THE ISM4
Once setup, there is typically no direct interaction with the ISM4. It will automatically respond to system
conditions, IR and RS232 Commands.
System ON Mode
When the
System Reference Device (Source 1)
is turned ON, via a power button on the device, an IR remote
control, a RS232 Command etc, the ISM4 will detect the change of state (OFF to ON) and automatically enter
System ON Mode
. In this mode, the first task that the ISM4 will take in response to the Off-to-On transition is to
execute the Power ON Macro associated with the Source 1 “Sense In” input. Recall that in executing this macro
(launched by a Source 1 “Sense In” trigger ONLY) the IR content of the first Command Structure will be
bypassed. Refer to the
Sense In
section for further information. Next, the ISM4 will ‘look’ at the
Source 2-4
Sense Inputs
, and if any one shows an OFF condition, the ISM4 will output the
ON Macro
associated with
that
Source
.
The
Source LED’s
will flash, by
Source
, when the
ON Macros
are being sent. The
Front Panel Source 1-4
LED’s
will illuminate solid green to indicate a sensed ON condition for
each
Source
. If for some reason a
particular Source does not respond to an ON Macro, the ISM4 will resend that macro. The ISM4 will resend an
ON Macro up to four times. During the resends, the
ISM4 Program LED
will flash
red
indicating that an error has
occurred in executing an
ON Macro
and that the Source for which the macro is being resent is out of sync with
the system.
The ISM4 will continually scan the
Sense Inputs
. As long as
Source 1
is ON (System ON Mode), if any of
Sources 2-4
turns OFF, for any reason, the ISM4 will automatically output the
ON Macro
for
that
Source
,
keeping all Sources synced to the
System ON Mode
.
System OFF Mode
When the
System Reference Device (Source 1)
is turned OFF, via a power button on the device, an IR remote
control, a RS232 Command etc, the ISM4 will detect the change of state (ON to OFF) and automatically enter
System OFF Mode
. In this mode, the first task that the ISM4 will take in response to the On-to-Off transition is to
execute the Power OFF Macro associated with the Source 1 “Sense In” input. Recall that in executing this macro
(launched by a Source 1 “Sense In” trigger ONLY) the IR content of the first Command Structure will be
bypassed. Refer to the
Sense In
section for further information. Next, the ISM4 will ‘look’ at the
Source 2-4
Sense Inputs
, and if any show an ON condition, the ISM4 will output the
OFF Macro
associated with
that
Source
.
The
Source LED’s
will flash, by
Source
, when the
OFF Macros
are being sent. The
Front Panel Source 1-4
LED’s
will turn off to indicate a sensed OFF condition for
each
Source
. If for some reason a particular Source
does not respond to an OFF Macro, the ISM4 will resend that macro. The ISM4 will resend an OFF Macro up to
five times. During the resends, the
ISM4 Program LED
will flash
red
indicating that an error has occurred in
executing an
OFF Macro
and that the Source for which the macro is being resent is out of sync with the system.
The ISM4 will continually scan the
Sense Inputs
. As long as
Source 1
is OFF (System OFF Mode), if any of
Sources 2-4
turns ON, for any reason, the ISM4 will automatically output the
OFF Macro
for
that
Source
,
keeping all Sources synced to the
System OFF Mode
.
RC68 Triggered Commands
Externally, the ISM4 will behave in exactly the same manner as described in the Sections:
System ON Mode
and
System OFF Mode
, when triggered by
RC68 Trigger Commands
. Internally if the ISM4 ‘sees’ the
RC68 Source
1 ON Command
it will look at the state of
Source 1
. If it is OFF the ISM4 will enter
System ON Mode
as
described. Conversely, if the ISM4 ‘sees’ the
RC68 Source 1 OFF Command
it will look at the state of
Source 1
.
If it is ON the ISM4 will enter
System OFF Mode
as described. If the ISM4 ‘sees’ the
RC68 Toggle Power
Command
, it will look at
Source 1
determine the state (ON or OFF) and output the
opposite state macro
.
Please Note that unlike the case of a “Sense In” trigger on Source 1,
the IR content of
Command Structure
number 1 on either the ON and OFF macro will be executed.
