Precis LT Instruction Manual
Executing a Test Switch
Execute a test switch to verify the system is working properly before attaching all inputs and outputs.
Aside from having signal cables (and a controller if applicable) attached, the system is ready to execute
switches when it ships from the factory.
Important: The Precis LT ships from the factory with a default switch of Input 1 to all outputs. Before
executing the test switch, you will need to disconnect the factory default switch.
The first two source and destination devices must be attached to the input and output connectors (for
specific connector information, see “Attaching Inputs & Outputs” on page 20). After the devices are
connected, power must be applied to the enclosure first and then to the devices before executing a test
switch.
You can execute a test switch from the following:
Front mounted control panel
AMX
control device
Control software such as APControl 3.0 or APWeb
BCS (Basic Control Structure) commands over an external controller
An external third-party controller
Executing a Test Switch
Before executing the test switch, make sure the first two source devices and the first two destination
devices are connected to the correct input and output connectors.
Important: Component signals require multiple input and output connectors (e.g., an RGsB signal
requires three connectors). All of the signal cables for that signal (including audio if switching
audio-follow-video) must be attached before executing the test switch.
Control Panel
To disconnect the factory default switch using the control panel:
1.
Press the Cancel Key to put the Panel in Switch mode.
2. Press Input Key 1.
The Video and Audio Level Keys illuminate.
Input Key 1 flashes and all of the output keys illuminate. (If none of the output keys illuminate,
press the Cancel Key and proceed to the following instructions to execute a test switch.)
3. Press each Output Key.
The Output Keys each disconnect (turn off) when pressed.
4. Press the Take Key.
All the illuminated keys turn off.
Input 1 is disconnected from all outputs.
