1 Introduction
Congratulations on purchasing your CDA-VP200N 1:2 High Resolution XGA
DA and/or CDA-VGA31 1:3 High Resolution XGA DA and/or CDA-VGA41
1:4 High Resolution XGA DA, which are ideal for:
Multi monitor applications or presentation systems requiring local
monitors and large screen display devices such as a projector
Rental and staging systems
Schools, churches, corporate applications
The package includes the following items:
CDA-VP200N or CDA-VGA31 or CDA-VGA41
Power adapter (12V DC input) and this user manual
2 Getting Started
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
3 Overview
The CDA-VP200N, CDA-VGA31, and CDA-VGA41 are high performance 1:2,
1:3 and 1:4 distribution amplifiers for XGA and higher resolution signals that:
Accept one input, provide correct buffering and isolation, and then
distribute the signal to 2, 3 or 4 identical outputs on high-density 15 pin HD
connectors
Have video bandwidth exceeding 400MHz, ensuring that the
machines remain transparent even at high-resolution graphics modes
such as UXGA (1600x1200)
Accept analog or digital syncs1 and provide ID Bit control2
1 Via a pair of underside switches. Note that both the Hs (horizontal sync) switch and the Vs (vertical sync) switch MUST be
set identically
2 Via an underside switch. Sometimes notebook computers refuse to output a VGA signal to an external VGA monitor. By
setting the ID BIT to ON, the notebook will output to an external VGA monitor
2
To achieve the best performance:
Connect only good quality connection cables, thus avoiding interference,
deterioration in signal quality due to poor matching, and elevated noiselevels (often associated with low quality cables)
Avoid interference from neighboring electrical appliances and position your
machines away from moisture, excessive sunlight and dust
Caution – No operator-serviceable parts inside unit.
Warning – Use only the input power wall adapter that is
provided with this unit.
Warning – Disconnect power and unplug unit from wall
before installing or removing device or servicing unit.
4 Your High Resolution XGA DA
This section describes each High Resolution XGA DA, as follows:
CDA-VP200N (see section 4.1)
CDA-VGA31 (see section 4.2)
CDA-VGA41 (see section 4.3)
The underside of the High Resolution XGA DA is identical on the
CDA-VP200N, CDA-VGA31, and CDA-VGA41 (see section 4.4).

Figure 4 and Table 4 define the switches on the underside of the High
Resolution XGA DA:
Figure 4: High Resolution XGA DA Underside
Table 4: High Resolution XGA DA Underside Features
# Feature Function
1 Hs (Horizontal Sync) Switch
2 Vs (Vertical Sync) Switch
Set both switches1 to Hi-Z (TTL2) if the source is, for example, a
digital graphics card. Set both switches to 75 (ANALOG) if the
source is analog based, for example, an RGBHV source with coaxial
cable for sync
3 ID Bit Switch Slide to the left to set to ON3; to the right to set to OFF4
1 Both the Hs and the Vs switches MUST be set identically (no harm will occur to the graphics source if the switches are set
to the wrong direction)
2 “Transistor-Transistor Logic” is a term used in digital electronics describing the ability of a device or circuit to be connected
directly to the input or output of digital equipment. Such compatibility eliminates the need for interfacing circuitry

5 Connecting Your High Resolution XGA DA
You can use the CDA-VP200N, CDA-VGA31, or the CDA-VGA41 to output
the XGA signal from a laptop or a PC. To output the XGA signal from a
computer graphics source to four displays, using a CDA-VGA41, as the
example in Figure 5 illustrates, do the following:
1. Connect a computer graphics source to the INPUT HD15F connector.
2. Connect the OUTPUT HD15F connectors to up to four acceptors, as follows:
Connect the OUTPUT 1 connector to an acceptor (for example, Display 1)
Connect the OUTPUT 2 connector to an acceptor (for example, Display 2)
Connect the OUTPUT 3 connector to an acceptor (for example, Display 3)
Connect the OUTPUT 4 connector to an acceptor (for example, Display 4)
3. On the underside of the CDA-VGA41:
Set both the Hs and Vs switches to Hi-Z (TTL)
Slide the ID Bit switch to the left to set to ON
4. Connect the 12V DC power adapter to the power socket and connect the
adapter to the mains electricity.
