VM0202HB Installation
To install the switch, refer to the installation diagram below as you perform the
following steps:
1. Use a grounding wire to ground the unit by connecting one end to the
grounding terminal, and the other end to a suitable grounded object.
Note: Do not omit the step. Proper grounding helps to prevent damage to
the unit from power surges or static electricity.
2. Connect the unit to up to two HDMI sources using HDMI cables.
Optionally secure the cables with ATEN LockPro
TM
.
Note: Please set the EDID Mode to port 1 EDID when you are connecting
an HDMI source with resolution 1080p @ 30Hz, see EDID Mode
Command, page 33.
3. Connect the unit to up to two HDMI-enabled displays using HDMI cables.
Optionally secure the cables with ATEN LockPro
TM
.
Note: Please set the EDID Mode to port 1 EDID when you are connecting
an HDMI-enabled display with resolution 1080p @ 30Hz, see EDID

Installing the RS-232 Controller
In order to use the RS-232 serial interface to attach a high-end controller (such
as a PC) to the VM0202H / VM0202HB, use a serial cable such as a modem
cable. The end connecting to the VM0202H / VM0202HB should have a 9-pin
male connector. Connect this to the serial interface on the rear of the VM0202H
/ VM0202HB.
For VM0202H installation, refer to step 1 from the installation diagram on
page 13.
For VM0202HB installation, refer to step 7 from the installation diagram on
page 14.
Note: To configure the controller serial port, see page 21.

Operation
Overview
This chapter provides detailed information on operating the VM0202H /
VM0202HB using the panel pushbuttons and IR remote controller.
Front Panel Pushbuttons
Video Output Pushbuttons
To manually select an HDMI source for an HDMI display, use the video output
pushbuttons located on the VM0202H / VM0202HB’s front panel to select the
output and input connections.
Press the video output pushbutton that corresponds to the port, which the
display is connected to. Pressing the pushbutton will cycle between the two
attached HDMI source devices (source 1 and 2) through the display devices.

Before using the remote control, a user must first plug the IR receiver into the
rear panel of the VM0202H / VM0202HB and place the receiver where the IR
signal can be reached (see IR Remote Control, page 8).
Switching the Input
To change the input source of an output display using the remote control, do
the following:
1. Press the output port button (1-2) that you want to change.
2. Within 2 seconds press the input port button (1-2) you want the output
port to display.
Note: For the change to occur the input number must be pressed within 2
seconds of pressing the output number.
3. Repeat steps 1-2 to change additional ports.
Turning the Outputs on / off
To turn an output on / off using the remote control, do the following:
1. Press the output port button (1-2) that you want to turn off.
2. Within 2 seconds press the ON or OFF button on the remote control.
Note: If the ON or OFF button is pressed after 2 seconds of pressing the
output port number, all the displays are powered on or off instead of
just the intended output port.
3. Repeat steps 1-2 to turn the output back on / off.
Turning All Outputs on/off
To have all output displays turned on or off, regardless of the current power
statuses, press the ON or OFF button on the remote control.

The Firmware Upgrade Utility
Introduction
The purpose of the Windows-based Firmware Upgrade Utility is to provide an
easy process for upgrading the VM0202H / VM0202HB. The program comes
as part of a Firmware Upgrade Package that is specific for each device.
As new firmware versions become available, new firmware upgrade packages
are posted on our website. Check the website regularly to find the latest
information and packages.
Downloading the Firmware Upgrade Package
To download the firmware upgrade package:
1. On our Website go to: Download - Firmware and choose the device
model, or from the VM0202H / VM0202HB product page under the
Resources tab, select Firmware. A list of available firmware upgrade
packages appears.
2. Choose the firmware upgrade package that you wish to install (usually the
most recent) and download it to your computer.

Upgrade Failed
If the Upgrade Succeeded screen doesn't appear, it means that the upgrade
failed to complete successfully. See the next section, Firmware Upgrade
Recovery, for how to proceed.
Firmware Upgrade Recovery
There are three conditions that call for firmware upgrade recovery:
When a firmware upgrade is manually aborted.
When the mainboard firmware upgrade fails.
When the I/O firmware upgrade fails.
To perform a firmware upgrade recovery, do the following:
1. Power off the device.
2. Connect the Micro USB Type-B cable to the firmware upgrade port.
3. Repeat the upgrade procedure.

Safety Instructions
General
Read all of these instructions. Save them for future reference.
Follow all warnings and instructions marked on the device.
This product is for indoor use only.
Do not place the device on any unstable surface (cart, stand, table, etc.). If
the device falls, serious damage will result.
Do not use the device near water.
Do not place the device near, or over, radiators or heat registers.
The device cabinet is provided with slots and openings to allow for
adequate ventilation. To ensure reliable operation, and to protect against
overheating, these openings must never be blocked or covered.
The device should never be placed on a soft surface (bed, sofa, rug, etc.) as
this will block its ventilation openings. Likewise, the device should not be
placed in a built in enclosure unless adequate ventilation has been provided.
Never spill liquid of any kind on the device.
Unplug the device from the wall outlet before cleaning. Do not use liquid
or aerosol cleaners. Use a damp cloth for cleaning.
The device should be operated from the type of power source indicated on
the marking label. If you are not sure of the type of power available,
consult your dealer or local power company.
To prevent damage to your installation it is important that all devices are
properly grounded.
The device is equipped with a DC adapter. This is a safety feature.
Position system cables and power cables carefully; Be sure that nothing
rests on any cables.
Never push objects of any kind into or through cabinet slots. They may
touch dangerous voltage points or short out parts resulting in a risk of fire
or electrical shock.
Do not attempt to service the device yourself. Refer all servicing to
qualified service personnel.
VM0202H / VM0202HB User Manual

Rack Mounting
Before working on the rack, make sure that the stabilizers are secured to
the rack, extended to the floor, and that the full weight of the rack rests on
the floor. Install front and side stabilizers on a single rack or front
stabilizers for joined multiple racks before working on the rack.
Always load the rack from the bottom up, and load the heaviest item in the
rack first.
Make sure that the rack is level and stable before extending a device from
the rack.
Use caution when pressing the device rail release latches and sliding a
device into or out of a rack; the slide rails can pinch your fingers.
After a device is inserted into the rack, carefully extend the rail into a
locking position, and then slide the device into the rack.
Do not overload the AC supply branch circuit that provides power to the
rack. The total rack load should not exceed 80 percent of the branch circuit
rating.
Make sure that all equipment used on the rack – including power strips and
other electrical connectors – is properly grounded.
Ensure that proper airflow is provided to devices in the rack.
Ensure that the operating ambient temperature of the rack environment
does not exceed the maximum ambient temperature specified for the
equipment by the manufacturer.
Do not step on or stand on any device when servicing other devices in a
rack.
