2.1 Quick Start
This quick start chart summarizes the basic setup and operation steps.

Overview

3 Overview
The VS-88DVI is an 8x8 DVI Matrix Switcher that accepts up to eight DVI
inputs and routes the selected DVI1input signal to any or all of eight DVI
outputs.
The VS-88DVI features:
•An OFF button to disconnect an output
•A PANEL LOCK button to prevent unwanted tampering with the
buttons on the front panel
•I-EDIDPro™ Kramer Intelligent EDID Processing™, an intelligent
EDID handling and processing algorithm that ensures Plug and
Play operation for DVI systems.
•16 preset memory locations for quick access to common
configurations
•2U height to fit into a standard 19” professional rack enclosure
Control the VS-88DVI using the front panel buttons, or remotely via:
•RS-232 serial commands transmitted by a touch screen system, PC,
or other serial controller
•The Kramer infrared remote control transmitter
•The ETHERNET
•An external remote IR receiver (optional), see Section 4.1
3.1 Defining the EDID
The Extended Display Identification Data (EDID2) is a data-structure,
provided by a display, to describe its capabilities to a graphics card (that is
connected to the display’s source). The EDID enables the graphic source to
“know” what kind of monitor is connected to the output. The EDID
includes the manufacturer’s name, the product type, the timing data
supported by the display, the display size, luminance data and (for digital
displays only) the pixel mapping data.
1 DVI-D (Digital). Note that only the digital signal (DVI-D) is available on the DVI connector

3.2 Recommendations for Best Performance
To achieve the best performance:
•Use only high-quality connection cables1to avoid 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-
88DVI away from moisture, excessive sunlight, and dust

4.1 Using the IR Transmitter
You can use the RC-IR3 IR transmitter to control the machine via the built-in IR
receiver on the front panel or, instead, via an optional external IR receiver1. The
external IR receiver can be located up to 15 meters away from the machine. This
distance can be extended to up to 60 meters when used with three extension
cables2.
Before using the external IR receiver, be sure to arrange for your Kramer
dealer to insert the internal IR connection cable3with the 3.5mm connector
that fits into the REMOTE IR opening on the rear panel. Connect the
external IR receiver to the REMOTE IR 3.5mm connector.

(see Section 7.6.1) for direct connection to the PC or a straight-through
cable (see Section 7.6.2) for connection via a network hub or network
router1.
7.6.1 Connecting the ETHERNET Port directly to a PC (Crossover
Cable)
You can connect the Ethernet port of the VS-88DVI to the Ethernet port on
your PC, via a crossover cable with RJ-45 connectors.
This type of connection is recommended for identifying the VS-88DVI
with the factory configured default IP address
After connecting the Ethernet port, configure your PC as follows:
1. Right-click the My Network Places icon on your desktop.
2. Select Properties.
3. Right-click Local Area Connection Properties.
4. Select Properties.
The Local Area Connection Properties window appears.
5. Select the Internet Protocol (TCP/IP) and click the Properties Button (see
Figure 5).
1 After connecting the Ethernet port, you have to install and configure your Ethernet Port. For detailed instructions, see the

10 Kramer Protocol 2000
The VS-88DVI is compatible with Kramer’s Protocol 20001(version 0.50)
(below)2. This RS-232/RS-485 communication protocol uses four bytes of
information as defined below. For RS-232, a null-modem connection
between the machine and controller is used. The default data rate is 9600
baud, with no parity, 8 data bits and 1 stop bit.

1st BYTE: Bit 7 – Defined as 0.
D – “DESTINATION”: 0 - for sending information to the switchers (from the PC);
1 - for sending to the PC (from the switcher).
N5…N0 – “INSTRUCTION”
The function that is to be performed by the switcher(s) is defined by the INSTRUCTION (6 bits). Similarly, if a function is
performed via the machine’s keyboard, then these bits are set with the INSTRUCTION NO., which was performed. The
instruction codes are defined according to the table below (INSTRUCTION NO. is the value to be set for N5…N0).
2nd BYTE: Bit 7 – Defined as 1.
I6…I0 – “INPUT”.
When switching (ie. instruction codes 1 and 2), the INPUT (7 bits) is set as the input number which is to be switched.
Similarly, if switching is done via the machine’s front-panel, then these bits are set with the INPUT NUMBER which was
switched. For other operations, these bits are defined according to the table.
3rd BYTE: Bit 7 – Defined as 1.
O6…O0 – “OUTPUT”.
When switching (ie. instruction codes 1 and 2), the OUTPUT (7 bits) is set as the output number which is to be switched.
Similarly, if switching is done via the machine’s front-panel, then these bits are set with the OUTPUT NUMBER which was
switched. For other operations, these bits are defined according to the table.
4th BYTE: Bit 7 – Defined as 1.
