Extron electronic 1616 HV, HVA Front Panel Operations

3-5CrossPoint Plus Matrix Switchers • Operation
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.
