3 Overview
The VS-88HDxl is a high-performance matrix switcher for 3G HD-SDI and
HD-SDI dual link signals. The unit can switch up to eight single link inputs
to any or all of eight single link outputs or four dual link inputs to any or all
of four dual link outputs.
In particular, the VS-88HDxl features:
• Operation of up to 2.97Gbps – enabling it to be used for standard
definition, high-definition and 3G high-definition serial digital
video signals (SD/HD/3G HD-SDI)
• SMPTE 259M, 292M, 424M, and 372M (dual link) compliance
and support for data rates of 270Mbps, 1483.5Mbps, 1485Mbps
and 2970Mbps
• Cable equalization up to 350m for SD1 signals, 140m for 1.5GHz
HD2
• Reclocking and equalization on each input, storing and recalling
setups, and a TAKE button for the execution of multiple switches
all at once
signals, and 120m for 3GHz HD signals
• The ability to switch genlocked video signals according to the
timing of the genlock reference input. Switching according to the
bi-level or tri-level genlock3
The VS-88HDxl 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:
input according to SMPTE RP-168
• 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
• By default, the VS-88HDxl is operated using the Kramer 3000
protocol (see section 7.1.9 for details of how to switch to Protocol
2000 and section 9.2 for the relevant protocol commands)
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 clearly
