Front Panel Operations
The following paragraphs detail the power-up process and then provide sample procedures for creating ties, sets of ties, and configurations; changing a configuration; viewing ties, sets of ties, and configurations; saving a preset; recalling a preset; and viewing and adjusting the audio level.
Power
On all models, power is automatically applied when the power cord is connected to an AC source. When AC power is applied, the switcher performs a self-test that blinks the front panel LEDs during the test. An error-free power up self-test sequence leaves the RGBHV and/or the Audio LED(s) on, depending on the model, and all other LEDs off.
The current configuration and all presets are saved in non-volatile memory. When power is applied, the last current configuration is retrieved. The previous presets remain intact.
If an error occurs during the self-test, the switcher locks up and will not operate. If your switcher locks up on power-up, call the Extron S3 Sales & Technical Support Hotline.
I/O grouping
I/O grouping is an RS-232/422 controlled feature that allows you to subdivide the front panel control of the matrix into four smaller functional subswitchers. Inputs and outputs can be assigned to one of four groups or not assigned to any group (figure 3-4). Once assigned to a group, inputs and outputs can only be tied within that group from the front panel. For example, a front panel operator cannot tie an input that is assigned to group 1 to an output that is assigned to group 2. Ungrouped inputs and outputs can be switched to outputs and inputs in any group.
