The Video Input Matrix

The video input matrix is found at the underside side of the codec. The matrix illustrates the combinations in which the video inputs can be connected.

About the matrix

Only one video input source from each row can be active at any time.

The numbers in the left column represents the Video Input Sources 1–5. The main connectors, which are used in basic setup, are marked in orange color on the codec.

Note that the Comp. 5 and S-Video (YC) 5 inputs uses the same physical connectors and can not be connected at the same time.

Congure the video inputs

You can congure the video input set tings from the Advanced conguration menu or by running API commands.

TheAdvancedcong uratio nmenu

Go to the on screen menu to congure the video input sources.

• Navigate to: Set tings > Advance d > Advanced Conguration

> Video > Input > Source 1. Congure the video input

connectors, quality and name. See the video input matrix. Only one video input source from each row in the matrix, can be active at any time.

• Navigate to: Set tings > Advance d > Advanced Conguration

presentation source.

TheAPIcommands

Open a telnet or ssh session, to the codec, to issue the API commands.

Congure the video input connectors. See the video input matrix. Only one video input source from each row in the matrix, can be active at any time:

Unused, but connected audio inputs must be set to O to avoid unwanted audio/noise.

Microphone/Line In 1–8 (XLR)

8 x Balanced XLR sockets, audio input 1–8. Main connector. The Microphone/Line In 1 is

the main connector for the microphone. All eight microphone inputs are for balanced

electret microphones, 48V phantom powered via XLR connectors.

The phantom powering of all eight XLR sockets can be individually switched o. The input will then be a balanced line level input.

All Microphone/Line In 1–8 are equipped with acoustic echo canceller.

Use Microphone/Line In 1–8 to connect to an external microphone amplier or an external mi xe r.

Default conguration. In default conguration, all Microphone/Line In inputs are enabled and congured as microphones.

HDMI In 3, 4

2 x HDMI connectors, audio input 3, 4 Typical use: Use HDMI In 3 or 4 (2–8 channels)

Line In 1–4 (RCA)

4 x RCA sockets, audio input 1–4 Audio Line In 1–4 are used when connecting

to PC and to external playback devices, such as VCR’s or DVD players.

Main connectors. The Line In 1 (left) and Line In 2 (right) are the main connectors to a PC.

Stereo. For systems with stereo I/O the audio inputs can be congured in stereo pairs:

• Connect the left channel to Line In 1 or 3

• Connect the right channel to Line In 2 or 4

Default conguration for Line In 1–2. In the default conguration Line In 1 and 2 are congured as stereo inputs for external playback devices, such as a PC.

Default conguration for Line In 3–4. In the default conguration Line In 3 and 4 are congured as stereo input pairs. The two inputs are paired with Line Out 3 and 4 respectively.

This pairing will avoid feedback situations that can arise when playback /recording devices are in standby mode (Loop suppression).

Line In 3 and 4 are used with external playback devices as VCR’s and DVD players.

Audio outputs, continued...

Line Out 1–4 (RCA)

4xRCA sockets, audio output 1-4 Can be congured as two stereo pairs. Main connectors. Line Out 1 (lef t) and Line

Out 2 (right) are the main connectors to the local loudspeaker system.

The local loudspeaker system may or may not include the DNAM (Digital Natural Audio Modul e).

Default conguration Line Out 1-2. In default conguration, Line Out 1 and 2 are congured as stereo speakers.

if a DNAM is present or SPDIF is active on Line Out 1, then Line Out 1 provides a digital stereo speaker signal and Line Out 2 is not active.

Default conguration Line Out 3-4. In default conguration, Line Out 3 and 4 are congured as stereo line out for external recording devices as VCR’s or DVD recorders.

if a DNAM is present or SPDIF is active on Line Out 3, then Line Out 3 provides a digital stereo speaker signal and Line Out 4 is not active.

COM port and Camera Control port

COM port

1 x COM (RS-232) data port for codec control and conguration through API commands.

Camera Control port

1 x Camera Control (RS-232) port for power and camera control (pan, tilt, zoom) using the VISCA™* protocol.

Main connector. The main camera is connected to the Camera Control port.

Power. Pin No. 4 on the Camera Control por t provides 12 V DC / 1 A to the main camera.

If more than one camera is connected, only the rst camera is powered from the codec. The additional cameras must be daisy chained by using a serial cable, and each will need an external power supply.

Additional cameras. For information about additional cameras, see the PrecisionHD Camera User Guide which is found on our web site, go to:

a n d +12 V. You can congure input/output integrations by using pre–

dened behavior. Exposure of states and commands for external control requires external programming.

For information about the API commands, see the API Guide for the codec, go to:

http://www.cisco.com/go/telepresence/

docs

Usage information

• A contact closure between the GND and a GPIO port pin is

detected as a low input signal.

• When used for voltage inputs, the GPIO port detects it as:

• Low signal for voltages 0 - 1 VDC

• High signal for voltages 2 - 12 VDC

• When used for outputs, the G PIO port acts as a switch

to GND, and is rated for 500mA @ 48V DC. The +12V pin provides +12 VDC, and is capable of sourcing up to 500mA.

• The GND connector is a common ground for all pins in the

GPIO port.
