Quick Start — CrossPoint 300 Matrix Switchers

Installation

Step 1

If desired, mount the switcher in a rack.

Step 7

Plug the switcher and input and output devices into a grounded AC source, and turn on the input and output devices.

Step 2

Turn off power to the input and output devices, and remove the power cords from them.

Step 3

Cable the switcher for RGBHV, RGBS, RGsB, RsGsBs, component/HDTV video, S-video, or composite video input and output.

Step 4 (HVA models)

Cable audio models for stereo audio input and output. High impedance is generally over

800 ohms.

CAUTION Connect the sleeve to ground. Connecting the sleeve to a negative (-) terminal will damage the audio output circuits.

Step 5

If desired, connect a control				5	1
system or computer to the
rear panel Remote RS-232/				9	6
RS-422 port. Wire the
connector as shown below.				Female

3	RX	Receive data	RX–	Receive data (–)
4	—	Not used	—	Not used
5	Gnd	Signal ground	Gnd	Signal ground
6	—	Not used	—	Not used
7	—	Not used	RX+	Receive data (+)
8	—	Not used	TX+	Transmit data (+)
9	—	Not used	—	Not used

Step 6

If desired, connect a control system or computer to the front panel Configuration (RS-232) port. Use an optional 9-pin D to 2.5 mm mini jack TRS RS-232 cable, part #70-335-01.

Definitions

Tie — An input-to-output connection.

Set of ties — An input tied to 2 or more outputs.

Configuration — One or more ties or sets of ties.

Current configuration — The currently active configuration (also called configuration 0).

Preset — A configuration that has been stored. One preset can be assigned to each input button. A preset becomes the current configuration when it is recalled.

Front Panel Controls

Input and output buttons select inputs and outputs. Input and output LEDs light to indicate video and audio ties.

Input buttons also select presets.

Output buttons also toggle video and audio mutes on and off in View-Onlymode.

On HVA models, the output LEDs also display the selected input’s audio level.

Enter button saves changes.

Preset button selects:

Save Preset mode to save a configuration as a preset.

Recall Preset mode to recall a previously- defined preset.

View button selects a View-Onlymode that prevents inadvertent configuration changes and allows output mutes to be toggled on and off.

On HVA models, View decrements the level. See “View, adjust the audio level” on the next page.

Esc button cancels selections in progress and resets the front panel LED indications. The Esc button does not reset the current configuration, the RGBHV or video and audio selection, any presets, or any audio level settings.

On HVA models, Esc increments the level. See “View, adjust the audio level” on the next page.
