3 Overview

The Kramer VS-48HDxl can be used as a high-performance 4x8 matrix

switcher or as a dual-link 2x4 switcher, which lets you simultaneously route

any of the inputs to any or all of the outputs for all SDI video signals, using

BNC connectors.

In particular, the VS-48HDxl features:

 Cable equalization up to 350m for SD

signals, 140m for 1.5GHz HD

signals, and 120m for 3GHz HD signals

 Operation of up to 2.97Gbps – enabling it to be used for standard

definition, high definition and the new 3G high definition serial digital

video signals (SD/HD-SDI)

 SMPTE 259M, 292M and 424M and 372M (for dual-link HD-SDI

signals) compliance and support for data rates of 270Mbps, 1483.5Mbps,

1485Mbps and 2970Mbps

 Reclocking and equalization on each input, storing and recalling setups,

and a TAKE button for the execution of multiple switches all at once

 Selector buttons that automatically light up in different colors—green,

when the VS-48HDxl detects a ‘standard definition’ signal, or blue, when

it detects a ‘high definition’ signal

 The ability to switch genlocked video signals according to timing of the

GENLOCK reference input. Switching according to the Bi-level or Tri-

level Genlock input according to SMPTE RP-168

The VS-48HDxl is housed in a 19" 1U rack-mountable enclosure, and is fed

from a 100-240 VAC universal switching power supply. The unit can be

controlled via the front panel buttons or via:

 An infrared remote control transmitter

 An infrared remote extension cable transmitter

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

touch screen system, or other serial controller

 The ETHERNET

 Remote contact closure for forced operation

1 Standard Definition (SD) means an NTSC or PAL compatible video format, consisting of 480 (for NTSC) or 576 (for PAL)

lines of interlaced video

2 High Definition (HD) means a video format, consisting of 720 active lines of progressive video or 1080 lines of progressive

or interlaced video

3 The sources must be genlocked to the GENLOCK input in order to switch cleanly
