注 意
About This Product
■ When connecting this product to another device (TV or DVD player), connect it with
the supplied frame ground (FG) cord, etc. so that the FG is shared between the
device and VA-1842. If this product is used without sharing the FG, there is a risk of
it malfunctioning.

About Installation
■ Install in a stable location. Also, do not install vertically. There is a risk of a
malfunction due to the temperature rising as a result of heat generation.
About Liquid Crystals
■ Due to the nature of LCD displays, the screen may have a few defective pixels
(always lit or never lit).
■ Do not touch any liquid that may leak from the LCD panel.
If the LCD panel is inadvertently damaged, liquid (liquid crystals) may leak from the panel. Keep the liquid away
from your mouth and skin and do not inhale the vapors. If any liquid crystals should contact your mouth or eyes,
wash them away immediately with water. Furthermore, if any liquid should adhere to your skin or clothing, wipe it
off with alcohol or the like and then wash it away with soap. Your skin or clothing may be damaged if liquid
crystals are left adhered.
Caution

Before Operation
xi
■ Be careful of glass shards from a broken LCD panel.
If the LCD panel is damaged, take care not to cut your hands, etc. on glass shards.
Touching a broken part may result in an injury.
■ The LCD panel is a high precision device so be careful with regard to the following
points when handling.
・Wiping with benzene, thinner, etc. will cause deterioration.
・Leaving water (or salt water) on the LCD panel will cause discoloration
・If the LCD panel is exposed to direct ultraviolet rays for a long time, the display quality may degrade. For example,
the deflector plate may become brown and the contrast may drop.
・Moisture from condensation or the like entering inside will cause color irregularities.
・Directly striking or bumping the LCD panel will cause cracks or other damage.
・Do not disassemble because getting leaking liquid crystals on your skin is dangerous.
If the Device Malfunctions or Trouble Occurs
■ In the event that a malfunction or trouble occurs, stop using the device, unplug the
power cord, and contact your dealer or an ASTRODESIGN sales representative.

About the VA-1842
1.1 Overview
The HDMI Protocol Analyzer VA-1842 (hereinafter referred to as the VA-1842 in this manual) enables the
protocol parts required in the development of HDMI transmitters to be checked. The HDMI video and audio can
be easily checked with the front LCD monitor and built-in speakers.
Furthermore, you can rewrite the performance information (EDID/SINK) of the VA-1842 unit so various kinds of
receivers (monitors) can be virtualized. The unit can thus be used in, for example, the development of devices
with HDMI terminals such as set-top boxes and DVD players.
In addition, the reception of sink device signals can also be checked by using the VA-1842 Generate function.
This manual collectively refers to devices with HDMI input terminals but without HDMI output terminals such as
monitors and TVs as receivers (monitors), and collectively refers to devices with both HDMI output terminals
and input terminals which perform output based on input signals as repeaters.
1.2 Features
ANALYZE (Measurement) Function
Measures the HDMI and DVI video timing.
Measures each packet content of HDMI.
Checks for differences from HDMI standard values.
Receiver (Monitor) Function
Enables HDMI input to be received.
Through Function
Enables checking the direct exchange of DDC/CEC of source devices and sink devices by allowing
VA-1842 input and output to pass through.
Generate Function
Enables receiving on the sink side to be checked using the timing and multiple patterns built into the
VA-1842. 3D timing can also be output.
Emulator Function
Enables the performance information of the VA-1842 unit to be changed to the performance of
various other monitors (e.g., high-definition TVs and NTSC compatible TVs).

2
Built-in LCD Monitor and Speakers
Each of 8-bit, 10-bit, and 12-bit HDMI video can be easily checked with the front LCDmonitor.
Linear PCM audio can be easily checked with the built-in speakers.
Program Function
Enables the data used when virtualizing monitors to be managed by programs.
This function allows you to easily change to the performance of various monitors by simply calling
programs.
There is also a function to pick out and group just the programs to be used from among many
programs.
Registration to USB Flash Memory Device
ANALYZE (measurement) data, programs, unit settings, and other data can be saved to the USB
flash memory device.
Hot Plugging Function
Enables a reset to be applied to a transmitter without disconnecting and connecting a cable between
the transmitter and VA-1842.
Log Trigger Function
Enables setting a trigger to retrieve ANALYZE data.
Line Monitor Function
Enables sending and receiving commands with the DDC and CEC lines.
HDMI Version 2.0 Compatible
Supports the timing and InfoFrame of HDMI 2.0.
