Description

The Extron CrossPoint 300 Series matrix switchers route RGBHV video, with or without audio (depending on the model), to any combination of outputs. The switchers can route multiple input/output configurations simultaneously.

Installation and Cabling

1. Mounting — If desired, mount the switcher in a standard 19" rack.

2. Video input connections — Connect an RGB video source to each set of input BNC connectors.

3. Video output connections — Connect RGB devices to each set of output BNC connectors.

NOTE On the 8 x 16, 16 x 8, 12 x 12, and 16 x 16 matrix sizes, the connectors are grouped by video plane. Connect the input or output on each video plane to the corresponding connector in the correct group (see the drawing at right).

4. Audio input connections (HVA models) — Connect balanced or unbalanced audio sources to each input 5-pole captive screw connector.

CAUTION Incorrect audio connector wiring can damage the switcher.

See “Audio Connections” at right to identify the tip, ring, and sleeve on the output connector.

6. Serial port connection — If desired, connect a remote host to the RS-232/422 port. See the drawing and table below to wire the connector.

7. Remote port connection — 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.

8. Power — Connect an IEC AC power cord.

Definitions

Tie — An input-to-output connection

Set of ties — An input tied to two or more outputs

Configuration — One or more ties or sets of ties

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

Global preset — A configuration that has been stored. Up to 32 global memory presets can be stored in memory. Up to 20 or 32 preset locations (depending on the number of input and output buttons) can be selected from the front panel to either save or retrieve a preset. When a preset is retrieved from memory, it becomes the current configuration.

CrossPoint 300 Matrix Switchers

Audio Connections

On HVA models, audio is input to and/or output from the switcher using captive screw connectors.

The examples below show unbalanced and balanced methods of wiring the captive screw audio connectors for input and output. If you are wiring a captive screw connector from an existing unbalanced audio cable, the white insulated wire is typically the left channel (tip) and the red insulated wire is typically the right channel (sleeve). There is no reliable standard for existing balanced audio cables.
