Safety Precautions
Before getting started, please read the following important safety precautions.
1. Be sure to ground yourself to prevent static charge when installing any internal
components. Use a grounding wrist strap and place all electronic components in any
static-shielded devices. Most electronic components are sensitive to static electrical
charge.
2. Disconnect the power cord from the GOT321W-521 prior to any installation. Be sure both
the system and all external devices are turned off. Sudden surge of power could ruin
sensitive components. Make sure the GOT321W-521 series is properly grounded.
3. Make sure the voltage of the power source is correct before connecting the
GOT321W-521 to any power outlet.
4. Turn off system power before cleaning. Clean the system using a cloth only. Do not spray
any liquid cleaner directly onto the screen.
5. Do not open the system’s back cover. If opening the cover for maintenance is a must,
only a trained technician is allowed to do so. Integrated circuits on computer boards are
sensitive to static electricity. To avoid damaging chips from electrostatic discharge,
observe the following precautions:
Before handling a board or integrated circuit, touch an unpainted portion of the
system unit chassis for a few seconds. This will help to discharge any static
electricity on human body.
When handling boards and components, wear a grounding wrist strap available
from most electronic component stores.

1.1 General Descriptions
The GOT321W-521 multi-touch panel PC adopts a 21.5-inch FHDTFT LCD with 250nit
brightness and supports the LGA1151 socket 8/9th gen Intel® Core™ i7/i5/i3 & Pentium®
processor (Tj 100°C) up to 35W, providing excellent computing performance and thermal
resistance. This fanless platform is particularly designed for operation under harsh
environments including steel refineries, oil pipes, ships, machine makers, and many more.
Having the abilities described below surely makes GOT321W-521 the most robust and
cost-effective solution.
Designed for extended operating temperature range and ingress protection
The GOT321W-521’s compact industrial design and fanless cooling system allow the panel
PC to sustain an extended operating temperature range between 0°C and +50°C, making the
system a power-efficient solution. It also features an IP65 front bezel for protection from liquid
and dust.
Reliable and stable design
The GOT321W-521 is specifically designed for vibration-prone environments, best for the
industrial machinery markets. With a patented anti-vibration design, the GOT321W-521 is able
to work in operation mode under 1.0G (10 ~ 500Hz), which has significantly improved system
reliability and sustainability.
NOTE
Heavy-vibration may sometimes cause the LCD screen to flash in white
color; however, it won’t affect the function of the product.

2.2 Jumper and Connector Settings
A jumper is a small component consisting of a jumper clip and jumper pins. Proper
configuration of jumper settings enables the GOT321W-521 to meet various application
purposes.
The illustration below shows how to set up jumpers: Place the jumper clip on two jumper pins
to close the jumper pins; remove the jumper clip from two jumper pins to open the jumper pins.
Figure 2-3: Definitions of pin settings
Before applying power to GOT321W-521, please make sure all of the jumpers and connectors
are in default positions, as listed in Table 2-1.
NOTE
Make sure the system is powered off prior to changing any default jumper
settings.

2.2.1 Restore BIOS Optimal Defaults Jumper (JP4)
This jumper allows you to clear the Real Time Clock (RTC) RAM in CMOS. You can clear the
CMOS memory of date, time, and system setup parameters by erasing the CMOS RTC RAM
data. The onboard button cell battery powers the RAM data in CMOS, which includes system
setup information such as system passwords.
To erase the RTC RAM:
1. Turn OFF the computer and unplug the power cord.
2. Remove the onboard battery.
3. Move the jumper clip from pins 1-2 (default) to pins 2-3. Keep the clip on pins 2-3 for about
5~10 seconds, then move the clip back to pins 1-2.
4. Re-install the battery.
5. Plug the power cord and turn ON the computer.
6. Hold down the <Del> key during the boot process and enter BIOS setup to re-enter data.

2.2.2 Auto Power On Jumper (JP6)
If JP6 is enabled for power input, the system will be automatically power on without the need to
press the soft power button. If JP7 is disabled for power input, it is necessary to manually
press the soft power button to power on the system
NOTE
Either one setting (AT/ATX switch or JP7) set to AT mode will be operated by AT
power.
2.2.3 COM Port Connector
This connector is a standard D-Sub connector for the COM1 serial port interface, which can be
set to use RS-232/422/485 mode via the BIOS setting (see section 4.4). The pin assignments
of RS-232/422/485 are listed in the table below.

2.4 Mounting the Panel PC
WARNING
Only trained and qualified technicians are permitted to mount the
product. To prevent accidental damage to the product or human injury
when mounting the product, at least two people are required to perform
the installation.
The GOT321W-521 panel PC supports four types of mounting methods.
⚫Panel mount
⚫Wall mount
⚫VESA arm mount
⚫Desktop mount
2.4.1 Panel Mount
A set of standard panel mount kits, including screws and particular hook brackets for panel
mounting, are bundled with the monitor package. Use the panel mount kits to mount the
GOT321W-521 into a panel.
Step 1 Prepare a panel frame to accommodate the panel PC. Ensure that the cutout
of the frame perfectly fits the monitor’s dimensions.
