We recommend that you:
Unpack the equipment carefully and save the original box and packaging
materials for possible future shipment
Review the contents of this user manual
Go to http://www.kramerelectronics.com/support/product_downloads.asp
to check for up-to-date user manuals, application programs, and to check if
firmware upgrades are available (where appropriate).
2.1 Achieving the Best Performance
To achieve the best performance:
Use only good quality connection cables (we recommend Kramer high-
performance, high-resolution cables) to avoid interference, deterioration in
signal quality due to poor matching, and elevated noise levels (often
associated with low quality cables)
Do not secure the cables in tight bundles or roll the slack into tight coils
Avoid interference from neighboring electrical appliances that may adversely
influence signal quality
Position your Kramer PT-201VGA away from moisture, excessive sunlight
and dust
This equipment is to be used only inside a building. It may only be
connected to other equipment that is installed inside a building.

PT-201VGA - Overview
3 Overview
The high quality PT-201VGA 2x1 VGA Switcher is amicro-sized mechanical
switcher designed for VGA/XGA/UXGA signals using high-density 15 pin HD
connectors. The PT-201VGA:
Accepts 2 inputs and lets you select either input using a switch located on
the front panel
With its passive design, eliminates the need for a power supply, and makes
it possible to operate “backwards” (as a 1x2 switcher), by taking a single
input and toggling between two displays
Has high-quality switching components and careful circuit design, ensuring
high bandwidth exceeding 1200MHz and minimal crosstalk

4 Connecting the PT-201VGA
Since the unit is passive, you can connect your PT-201VGA as a 2x1 VGA
switcher (see Section 4.1) or as a 1x2 VGA switcher (see Section 4.2).
4.1 Connecting the PT-201VGA as a 2x1 VGA Switcher
To use your PT-201VGA as a 2x1 VGA switcher, connect the 2 VGA INPUTS, as
the example in Figure 2 illustrates:
1. Connect up to 2 VGA sources to the INPUT 15-pin HD connectors, as
follows:
A VGA source (for example, PC graphics 1) to INPUT 1
A VGA source (for example, PC graphics 2) to INPUT 2
2. Connect the 15-pin HD OUTPUT connector to the VGA acceptor (for
example, a display).
3. Push in the SELECT switch to route input 1, or release it to route input 2.

4.2 Connecting the PT-201VGA as a 1x2 VGA Switcher
To use your PT-201VGA as a 1x2 VGA switcher, as the example in Figure 3
illustrates, connect as follows:
1. Connect the VGA source (for example, PC graphics) to the 15-pin HD
OUTPUT connector.
2. Connect the INPUT 15-pin HD connectors to up to 2 VGA acceptors, as
follows:
INPUT 1 to a VGA acceptor (for example, display 1)
INPUT 2 to a VGA acceptor (for example, display 2)
3. Push in the SELECT switch to route the source signal to display 1 (at input
1), or release it to route the source signal to display 2 (at input 2).
