VSA-51
Time Delay
Inserts a delay to wait before executing the next command in the action sequence
Serial Port
Selects which serial port to assign to the string when it is inserted into the command list. Strings assigned to the Receiver
will go to the connected display. Strings assigned to User Interface will be sent through the VSA-UI-DP serial port.
Serial String
Used for inserting one ASCII Serial command at a time. Hexadecimal codes may be inserted beginning with an &h
followed by a hexadecimal code. For example, a carriage return can be inserted by appending the command with &h0d
IR Protocol
Specifies the IR protocol to use. Choose from the list of compatible protocols.
IR Address
Enter the IR Address in decimal format
IR Command
Enter the IR command in decimal format
Button LED
Selects which button LED to control.
Behavior
Choose to turn LED on, off, or blink.
Action Command List
This box shows the individual commands that make up the entire action sequence. Commands are inserted into the list in
the order they are added, top to bottom. Commands can be reordered by clicking and dragging them to a new position.
Commands can be deleted by clicking the trash can symbol. Click the “Clear” button to delete all the contents of the
action.
Actions are very flexible in that they can be configured in a variety of ways and even linked together to form compound
actions. This flexibility makes them versatile but also makes them a bit tricky to understand at first. For example, if you
wanted to turn down lights, lower a projection screen, and turn on a projector from a single button press then you would
create a compound action consisting of individual actions. First, you would create an action to turn down the lights, either
with IR, RS232, or using a discrete output to open or close a relay. Do the same for the screen and projector. Finally,
create an action that executes all three actions. You can also include a delay in between each action. This is just a basic
example of how to use actions.
3.2.4.3.1
Action Sequence
Notice in the action window for SRCVGA1 the action sequence is:
BL6,1
BL7,0
BL8,0
BL9,0
BL10,0
(VGA1)
Let’s break this action sequence down and explain what is going on.
The first 5 commands are actually turning Button LEDs on/off while the last command tells the VSA-51-R to switch to
VGA1 input. There may be some latency when processing an action sequence so the first thing we want to do is set the
proper button lighting on the keypad to minimize the user perception of any latency.
