OPERATING THE ISM4

ISM4 INSTALLATION & PROGRAMMING MANUAL

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 2-4turns 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 2-4turns 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.

ISM4 specifications

The Xantech ISM4 is an innovative multi-zone audio distribution system designed to enhance the listening experience across various environments. This advanced model is particularly suitable for residential and commercial applications, where high-quality audio distribution is crucial.
