2. Introduction
FAT820w is a three-in-one programmable keyboard that built-in with LCD and USB HID host (USB
Keyboard interface), also enables to connect external Barcode scanner or RFID reader (keyboard emulation)
as optional. Moreover, FAT820w is space-saving design and provides easy operation.
FAT820w provides both Wi-Fi and 100Base-T Ethernet interfaces for user selection. If you would like to
switch to Wi-Fi or Ethernet mode, Please power off at first, then connect an external Keyboard and keep
pressing No.6 key, then power on till the screen pops up “WIFI Enable? (1)Yes (2)No”, further you enable to
choose which interface you prefer.
FAT820w supports many kinds of operation modes (buffer/un-buffer mode; asterisk/digit displaying;
wall-mount/desk-top viewing); you can set any one of modes to meet your application by Paragraph 6-G
command. Once you set it, FAT820w will keep this setting in memory (EEPROM). When you power-up
FAT820w, FAT820w will take the last setting for the unit.
FAT820w has built 12 text pages to quickly show messages. You just give the number of messages by
Paragraph 6-B command. FAT820w will show that message immediately. If you want to show message
directly or change messages in one of 12 text pages, please refer to Paragraph 6-L command.
FAT820w has RFID reader reserved at the hardware (Standard version do not build in).If your FAT820w
has RFID reader; you can enable/disable reader by Paragraph 6-D command. If you disable reader, the reader
will get no action, until you enable the reader. The reader will reply Notice Message, refer to Paragraph 6-O.
For keypad, you can enable/disable keypad by Paragraph 6-E command.
Note: When you power-on FAT820w every time, both reader and keypad are always enabled, even
though you did disable the reader or keypad last time.
3. Installation

Wi-Fi enable and then choose station mode
2) Plug in the DC power adaptor to the power jack on the
FAT820W.
3) Plug the adaptor to the power line.
4) Waiting for connection of Wi-Fi
5) Build connection with IP and Port shown at the screen.
C. Wireless network – AP Mode(access point)
1) Do Wi-Fi setting by USB keyboard step and switch to
Wi-Fi enable and then choose ap mode
2) Plug in the DC power adaptor to the power jack on the
FAT820W.
3) Plug the adaptor to the power line.

5. Operations
Fat820w always creates a server and waiting for PC or other device building connection with TCP port
(factory default is 1001). And fat820w also provide a client by Paragraph 6-O command, trying to connect
with server provide by host every 30 seconds.
When you start up FAT820W, FAT820W will set the boot-up status from memory (EEPROM). Then sound
a beep and LCD shows the start-up page. After that, FAT820W will stay at stand-by state. You can give a
command to FAT820W. For example, show a message to direct customer to do some action (refer to Paragraph
6-B command). You can also blink the LCD by Paragraph 6-I command to attract the customer attention.
You can press any key in the keypad. Please make sure keypad is enabled. If keypad is at “disable”, keypad
doesn’t work. The power-up state is at “enable”. When you press the first key, the screen on LCD will be
cleared, and the key will be shown on the left-top side. Following key-in will be left-to-right top-to-bottom
showing on LCD by sequence. The key-in digits are 32 maximum. It will be ignored, if key-in digits over 32
maximum.
If LCD always show asterisk sign(*) when you press key. It means FAT820W is on “asterisk” displaying
type. In fact, asterisk sign is just only for displaying. Real key is as the same as you pressed. You can change
displaying type as “normal” type by Paragraph 6-G command. Then the LCD displaying will show what you
are pressing.
The FAT820W have 2 operation modes. One mode is Un-Buffer mode. When you press one key,
FAT820W send out that key(ASCII) by ETHERNET interface immediately. And the other one is Buffer mode.
It will be kept in buffer, when you press keys, it will not send out all keys(ASCII) in the buffer by
ETHERNET interface until you press ENTER and then the key-in digits on LCD will be erased. The buffer
size is 32 maximum. It will be ignored, if key-in digits over buffer size 32 digits.

CLR key is used to backspace the last key.
ESC key is used to erase all keys in the LCD and buffer.
If you have already key-in some keys and then stop key-in over 10 seconds, FAT820W will erase all keys
in LCD and buffer. And issue a timeout notice to host (refer to Paragraph 6-M).
Host can erase LCD and buffer by Paragraph 6-C command.
If you need reader to read barcode/magnetic stripe card, please make sure reader is enabled. If the card
data can’t be decoded, it sends an error notice to host. If the card data is correct, it sends the card data to host,
and sounds a beep.
You can get the existing information and status on FAT820W by Paragraph 6-A command. We suggest you
may use this command to make sure the correct correspondent settings you want between host and FAT820W.
FAT820W support 2 viewing. The one is desktop viewing; and the other one is wall-mount viewing. Once
you change the viewing, the FAT820W will keep this setting and restart itself. So, please re-connect this
FAT820W on ETHERNET network. After restart, you typing key and send text message will meet your
specific viewing, but not the saved graphics message page. For the saved graphics message, we suggest you
redraw and save it again.
