RS232 CONTROL
Delay Control
Enables the adjustment in milliseconds of source audio
delay to fine-tune synchronization between audio and
video for perfect audio timing on all connected screens
by delaying the delivery of extracted audio of the HDMI
source to the display.
This is particularly useful for lip-sync issues or avoiding
distracting fractional mistiming between multiple display
devices outputting the same content in the same location.
Audio from each connected HDMI source can be adjusted
independently values of 50ms, with a maximum delay of
500ms (or half a second). Delay values below:
Zero > 50ms > 100ms > 150ms > 200ms > 250ms >
300ms > 350ms > 400ms > 450ms > 500ms
All connected HDMI inputs can be set to the same delay
value and, as with previous audio settings, pressing
Status will reveal the current delay control Status of
outputs.
vii) Input/Output Switch
The input/output switch allows selection of output port
(display) and input port (source) for specific combinations
of displays and sources within the matrix, with input/
output selections states able to be saved and previously
saved states loaded in to the switch.
Configuration Example – Selecting Inputs and
Outputs
To select between Input ports (sources) for Output port 2
(display):
Input port 3 is selected in Output Block 2.
Click twice or press #5 directly to select
Input port 5 for Output port 2.
To select the same Input port for all Output ports
choose an Input port from the 'All Set' drop down box.
To save a configuration, click Save button 1, 2
or 3. Recall previously saved output/input configurations
by clicking State button 1, 2 or 3.
NOTE
Only 3 configuration states can be saved or
recalled – saving a configuration will automatically
overwrite the previously saved state. This action
cannot be undone.
To set all output ports to a particular input, select
desired input port number 1-8 from the drop-down.
viii) Control Commands and Codes
COM Port Settings
The RS232 connection on the matrix is female DB9.
Users can use a USB to UART cable or a direct serial
cable for matrix control. See below for control system
configuration.
1
Input port selection 1 ~ 8 – red when selected
2
Previous/next selection buttons - scrolls numerically between input sources
3
Output ports selection blocks 1 ~ 8
4
Recalls previously saved output/input configurations by clicking State
buttons 1 ~ 3
5
Save output/input configurations by clicking Save buttons 1 ~ 3
6
Selects a specific input port from 1 ~ 8 to be used for all output ports
