Getting Started

Overview

3 Overview

The VS-88HD is an HDTV compatible high performance matrix switcher for

HD-SDI and SDI digital video signals. It lets you simultaneously route any of

the eight inputs to any or all of the eight outputs. Switching during the

vertical interval ensures glitch-free switching with genlocked sources. In

particular, the VS-88HD features:

Input and output signals on BNC connectors

A looping analog sync input with selectable sync signal termination

Switching synchronization, letting you synchronize to either the

external reference or incoming video

Automatic reclocking and equalization on each input

Each input button on the front panel automatically lights up when

the VS-88HD detects a video signal on that input

Switching according to the Bi-level or Tri-level Genlock input

The storing and recalling of setups

A Take button for the execution of multiple switches all at once

A 7-segment display

The VS-88HD, which is housed in a 19" 1U rack mountable enclosure, and is

fed from a 90-240 VAC universal switching power supply, can be controlled

via the:

Front panel buttons

Remotely, by RS-232 or RS-485 serial commands transmitted by a

touch screen system, PC, or other serial controller

To achieve the best performance:

Connect only good quality connection cables, thus avoiding

interference, deterioration in signal quality due to poor matching, and

elevated noise levels (often associated with low quality cables)

Avoid interference from neighboring electrical appliances that may

adversely influence signal quality and position your Kramer VS-88HD

away from moisture, excessive sunlight and dust

5 OUT SELECT Buttons Select the output to which the input is switched

6 STO (STORE) Button Pressing STO followed by an INPUT / OUTPUT button stores the current

setting

7 RCL (RECALL) Button Pressing the RCL button and the corresponding INPUT / OUTPUT key

recalls a setup from the non-volatile memory

Installing on a Rack

5 Installing on a Rack

This section describes what to do before installing on a rack and how to rack

mount.

Connecting Your VS-88HD 8x8 SD/HD-SDI Matrix Switcher

6 Connecting Your VS-88HD 8x8 SD/HD-SDI Matrix Switcher

You can use your VS-88HD to switch one of the eight standard definition /

high definition SDI inputs to any or all of the eight standard definition / high

definition SDI outputs, as the example in Figure 2 shows.

To connect the VS-88HD 8x8 SD/HD-SDI Matrix Switcher, do the following

1. Connect up to eight SDI sources to the SDI INPUT BNC connectors (for

example, an HD/SD SDI camera to input 1 and an SDI player to input 8).

2. Connect the SDI OUTPUT BNC connectors to up to

eight SDI

acceptors (for example, output 1 to a non linear editor, and output 8 to an HD

SDI display).

3. Set the dipswitches (see section 6.1).

4. As an option

, connect:

A Genlock source to the SYNC BNC connector

The LOOP BNC connector to the GENLOCK connector of the next

unit in the line, and release the TERM button for looping

5. Connect a PC and/or controller (if required), to the:

RS-232 port (see section 6.2), and/or

RS-485 port (see section 6.3), and/or

6. Connect the power cord

1 Switch OFF the power on each device before connecting it to your VS-88HD. After connecting your VS-88HD, switch on

its power and then switch on the power on each device

2 When only one output is required, connect that output, and leave the other outputs unconnected

3 Not illustrated in Figure 2

4 Pushed in terminates the input. Release when the input extends to another unit

5 We recommend that you use only the power cord that is supplied with this machine
