ISM4 FEATURE DESCRIPTIONS
Figure 1 – ISM4 Front Panel Features
ISM4 FRONT PANEL FEATURES
1. IR Learning Eye. The IR Learning Eye allows teaching IR Commands to the ISM4 for programming Source
ON and OFF Macros and Command Structures.
2. Source 1-4 LED’s. These LED’s are primarily used to indicate the sensed state of a corresponding system
device (Source 1-4). When a sensed device is ON, the LED for that device will illuminate solid green. When
that device is OFF the LED will be OFF. A Source LED will flash green when the ISM4 is outputting IR for that
source. These LED’s will also illuminate individually during IR Programming to indicate which device the IR
Commands being learned are being associated with. Several of the function buttons on the front panel are
capable of launching different functions based on the current programming state and the duration of the
button press. The allowed elapsed times are; 1 second, 2 seconds, 5 seconds and 10 seconds. To eliminate
the burden on the programmer to have to keep track of time, the ISM4 will prompt the programmer when all
but the 1 second elapsed time intervals have expired. This is true for all buttons that have time
dependencies. Upon initiation of a press of a button with time dependencies, the unit starts tracking time.
Upon crossing the 2 second threshold, the unit will quickly flash the current active SOURCE LED. If the
button remains pressed beyond this point the unit continues to monitor elapsed time. After 5 seconds of
continuously pressing the button, the current active SOURCE LED will blink once again. Finally after 10
seconds of a continuous press, the LED will blink a third time. Given that there is not time dependency that
exceeds 10 seconds the unit starts to blink rapidly to indicate that the max time duration has been exceeded.
• First Blink: 2 second elapsed time indication.
• Second Blink: 5 second elapsed time indication.
• Third Blink: 10 second elapsed time indication.
• 4
th
+ (Rapid Blink): Maximum Elapsed time exceeded indication
3. Program LED. This LED will illuminate different colors during the progressive steps of Source Programming
to indicate which Macro (by Source) is being programmed.
Normal Mode
• LED Off – Normal use mode. (Power Management)
• Solid Red During IR Generation – Retry Source ON or OFF Macro (up to five times).
• Flash Red – Flash at a rate of 1/3 of a second indicates that the unit is processing a long delay.
