3 Overview
The high quality Kramer VS-88DTP is an 8x8 DVI - Twisted Pair Matrix
Switcher that accepts up to eight DVI inputs and routes any or all of them to
any or all eight TP (Twisted Pair) outputs for connection to compatible TP
receivers, for example, the PT-572HDCP+ or TP-574.
The VS-88DTP features:
•I-EDIDPro™ Kramer Intelligent EDID Processing™, an intelligent
EDID handling and processing algorithm that ensures Plug and Play
operation for DVI systems
•An OFF button to disconnect one or all outputs
•A LOCK button to prevent unwanted tampering with the front panel
buttons
•16 preset memory locations for storing configuration configurations
•1U height that fits a standard 19” professional rack enclosure
You can control the VS-88DTP using the front panel buttons, or remotely
via:
•RS-232/RS-485 serial commands transmitted by a touch screen
system, PC or other serial controller
•The Kramer infrared remote control transmitter
•Ethernet over a LAN
•An external remote IR receiver (optional, see Section 4.1)
3.1 Recommendations for Best Performance
To achieve the best performance:
•Use only high-quality connection cables1
•Avoid interference from neighboring electrical appliances that may
adversely influence signal quality and position your Kramer
VS-88DTP away from moisture, excessive sunlight, and dust
to avoid interference,
deterioration in signal quality due to poor matching, and elevated
noise levels (often associated with low quality cables).

3.2 Using Twisted Pair Cable
Kramer engineers have developed special twisted pair cables to best match
our digital twisted pair products; the Kramer BC-DGKat524 (CAT 5
24 AWG), the Kramer BC-DGKat623 (CAT 6 23 AWG cable), and the
Kramer BC-DGKat7a23 (CAT 7a 23 AWG cable). These specially built
cables significantly outperform regular CAT 5/CAT 6/CAT 7a cables.

4.1 Using the IR Transmitter
You can use the RC-IR3IR transmitter to control the device 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 15m (48ft) away
from the device. This distance can be extended to up to 60m (197ft) 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 cable9F
3with the 3.5mm mini jack
that fits into the REMOTE IR opening on the rear panel. Connect the
external IR receiver to the REMOTE IR 3.5mm mini jack.

6.1 Connecting to the VS-88DTP via RS-232
You can connect to the VS-88DTP via an RS-232 connection using, for
example, a PC. Note that a null-modem adapter/connection is not required.
To connect to the VS-88DTP via RS-232:
•Connect the RS-232 9-pin D-sub rear panel port on the
VS-88DTP unit via a 9-wire straight cable (only pin 2 to pin 2, pin 3
to pin 3, and pin 5 to pin 5 need to be connected) to the RS-232 9-pin
D-sub port on your PC
6.2 Connecting to the VS-88DTP via RS-485
You can operate the VS-88DTP via the RS-485 port from a distance of up
to 1200m (3900ft) using any device equipped with an RS-485 port (for
example, a PC). For successful communication, you must set the RS-485
machine number and bus termination.
To connect a device with a RS-485 port to the VS-88DTP:
1. Connect the TxD+ pin on the RS-485 port of the PC to the A pin on
the RS-485 port on the rear panel of the VS-88DTP.
2. Connect the TxD–pin on the RS-485 port of the PC to the B pin on the
RS-485 port on the rear panel of the VS-88DTP.
3. If shielded TP cable is used, the shield may be connected to the G
(ground) pin on the unit.
6.2.1 Setting the RS-485 Machine Number
When several VS-88DTP units are connected, the machine number
determines the unique identity of the VS-88DTP on the bus (see Table 3).
Note:
•When using a stand-alone VS-88DTP unit, set the machine number
to 1 (factory default)
•When connecting more than one VS-88DTP, set the first machine
(connected via RS-232) to be machine number 1. The other
VS-88DTP units must each be set to a unique machine number
between 2 and 16
The machine number on the VS-88DTP is set using the DIP-switches on the
rear panel.
To set the RS-485 machine number using the DIP-switches:
Figure 4 illustrates the factory default MACH # DIP-switch settings.

6.2.2 Setting the RS-485 Bus Termination
DIP-switch 1 sets the RS-485 bus termination of the VS-88DTP. Only the
first and last physical units on the RS-485 bus must be terminated, all others
must be unterminated. Moving the DIP-switch up turns the termination off
(default), moving the switch down enables the termination.
Figure 5 illustrates the factory default PROG TERM DIP-switch positions.

6.2.3 Connecting and Controlling Multiple VS-88DTP Devices
You can daisy-chain up to 16 VS-88DTP devices with operation via
RS-232 from a PC or serial controller (see Figure 6).
To daisy-chain up to 16 VS-88DTP devices:
1. Connect the RS-232-1 port1
6.1
on the first VS-88DTP device to the PC
(see Section ).
2. Connect the RS-485 terminal block port on the first device to the
RS-485 port on the second device, and so on for all devices. (Connect
A to A, B to B, and G to G.)
3. Set the machine number and termination as follows:
The first device is machine number 1 and the subsequent seven
devices are machine numbers 2 to 16 (see Section 6.2.1)
Terminate the first and last devices, that is, terminate machine
numbers 1 and 16. Ensure that all other devices are
unterminated (see Section 6.2.2)

6.3 Connecting to the VS-88DTP via Ethernet
You can connect the VS-88DTP via Ethernet using a crossover cable (see
Section 6.3.1) for direct connection to the PC, or a straight-through cable
(see Section 6.3.2) for connection via a network hub or network router1
6.3.1 Connecting to the Ethernet Port directly to a PC
.
You can connect the Ethernet port of the VS-88DTP 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-88DTP 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 7).
