ISM4 INSTALLATION & PROGRAMMING MANUAL

IR Receiver and receives IR signals from the receiver. IR signals input on this jack can control the ISM4 and pass through to control the individual sources via the Source 1-4 IR Outputs.

12.IR Control. One 2-circuit (mono) 3.5mm mini jack connects to a normal Emitter Output on an IR repeater system or IR Output on a system controller or A/V Receiver. IR signals input on this jack can control the ISM4 and pass through to control the individual sources via the Source 1-4 IR Outputs.

13.Power. 2.1mm coaxial jack connects to the included 12VDC 0.5A Power Supply (Xantech Part No 781ERGPS).

14.Expansion. One, 2-circuit (mono) 3.5mm mini jack connects to the Source 1 “Sense In” on a secondary ISM4 for system sync of three additional devices. When the Source 1 “Sense In” on the Primary ISM4 senses an ON state (12VDC), this jack outputs 12VDC to the Source 1 “Sense In” on the Secondary ISM4 to indicate the system ON state. The Source 2-4 devices on the Secondary ISM4 will then sync to the system as programmed (turn ON). When the Source 1 “Sense In” on the Primary ISM4 senses an OFF state (0VDC), this jack outputs 0VDC to the Source 1 “Sense In” on the Secondary ISM4 to indicate the system OFF state. The Source 2-4 devices on the Secondary ISM4 will then sync to the system as programmed (turn OFF).

15.RS232. One, 3-circuit (stereo) mini jack connects to the RS232 Output on a system control device such as an A/V Receiver, Whole House System Controller, etc. RS232 Commands Input on this port can trigger ISM4 IR output for Source 1 Power (discrete ON/OFF, toggle ON/OFF) as well as Query Source Power State and System info. This Port is bi-directional and will automatically send ISM4 System Status Info (Provided Automatic Source Power State Notifications are enabled. Refer to the RS232 Control and Programming section) when any Source state change has occurred or when queried by the RS232 control device.

16.Sense In. Four, 3-circuit (stereo) 3.5mm mini jacks connect to any of the Xantech SM Series Sensor Modules. The ON/OFF state for each of Sources 1-4 will be detected by a Sensor Module appropriate for that device, (i.e. SMVID01 Video Sensor for a DVD Player, SMVLT01 Voltage Sensor for a device with a 12V AC or DC output such as an A/V Receiver or Whole-House System Controller). Each "Sense In" Jack is associated with two IR Macros (ON/OFF) and a Source IR Output.

Before proceeding with this discussion, it is important to note that the Programming Procedure imposes a requirement on the Source 1 (System Reference Device) macros that it does not impose on any other macros. The requirement is as follows; on either the ON or the OFF Macros, the ISM4 assumes that the IR content (if programmed) of the first Command Structure (refer to the COMMAND STRUCTURES section for a thorough description of Command Structures) be a Power Command. It is left up to the programmer to ensure that this rule is strictly abided by. The problem is as follows; if the System Reference device is manually (or by Remote Control) turned on, the resulting transition on the System Reference Sense Input would be an Off-to-On transition. As a result, the ON Macro would be launched. Given that a Toggle Power command is present in the macro, the Reference device would immediately be turned off. Therefore, Toggle commands would not be permissible. The programmer would be limited to discrete type of Power IR ONLY. Unfortunately, Discrete IR commands are not as common as Toggle commands. To avoid this difficulty, the requirement stated above was imposed. For any “Sense In” transition detected by the ISM4 on the Source 1 (System Reference Input), the IR Content of the first Command Structure (containing a Power Command) will be bypassed. If a Delay is programmed, however, it will be processed. The end result is that regardless of whether or not a Toggle or a Discrete Power Command is present, the undesirable situation described above would not take place. Hence, the more prevalent Toggle Power commands can be utilized without any adverse effects at all. Please note that the IR content of Command Structure 1 is only bypassed during execution of a “Sense In” initiated macro on the Source 1 (System Reference) Input. On every other case, the full macro will be executed. For instance, if the trigger is a “Discrete Power On” RS232 (or IR) command, the entire macro would be executed. As a result, having executed the first Command Structure, the System Reference Device will be turned on as desired.
