standard AA batteries.
The RF-2900 is a user friendly and very
affordable radio frequency handheld terminal for communication
with the Host Computer via a Base Unit which attaches to
the RS-232 port. The Host Computer sends prompt and
command to the Base Unit which transmits them to the terminal
to instruct the operator what to do. The data scanned or
keyed is immediately transmitted to the Base Unit and sent to
the Host Computer.
RF-2900 allows you to easily implement an
RF application for warehouse or retail management, etc.
For example, if your company is currently using an accounting
software with Purchase Order, Sales Order, and Inventory Module,
you may easily add RF capability at a very affordable cost,
to do Receiving, Picking, Shipping, and Physical Inventory.
All it takes is to develop an interface program to extract information
from the data base of the accounting software and send them to
the terminal, and to receive the data from the terminal and save
to the data base.
Easy to Implement
There is no programming on the terminal.
The terminal acts like a dumb terminal. All the programm
-ing is on the host computer by using any programming language.
The only requirement is the ability to program simple read/write
statements to an RS-232 port.
Multiple Terminals per Base Unit
The Base Unit attaches to the Host Computer via RS-232 port.
Up to 8 terminals can be controlled per Base Unit.
Each terminal has a unique ID code (1-8). Data received
by the Host have the transmitting terminal’s ID as a header
and the Host addresses the terminal with the ID.
Menu Driven Operation
When you power up the RF-2900, you will see the
MAIN MENU which consists of three Menus:
In this menu, the user may login the host computer, receive
prompt, command, and data from the host, and transmit bar code
or keypad entry data to the host.
In this menu, you may walk around your office
or warehouse to make sure that the base unit covers the area you
expect or you may add relay units to extend the coverage.
In this menu, you may configure Bar Code Symbologies,
Terminal ID, Network Channel, Beep Tone, Function Keys, and RS-232
parameter for the portable printer.
Versatile Input Devices
RF-2900 can auto-discriminate between all the
popular bar code symbologies: Code 39, UPC/EAN, COdabar, Interleaved
2 of 5, MSI/Plessy and Code 128. It supports all types of bar
code input devices such as: Wand, CCD, Laser scanner or magstripe
RF-2900 supports most of the RS-232 interfaced
printers to generate labels, tickets, or receipts.
Host sends the Prompt/command string to the RF-2900
<SOT>n M <Prompt>
^ <Command> ~ <Data>< CR>
<SOT> is ASCII
n is terminal ID, can be from 1 to 8.
M is the current Prompt ID from host, you may
define the prompt ID to keep track of the status of the terminal.
<Prompt> is the message and prompt you want
to display on terminal to instruct the operator what to do next.
You may use the following string to specify on which line the
message to be displayed and to position the cursor.
And several of the strings can be combined in one prompt.
Clear entire screen
Clear Line n
Display Message on Line n
Position the cursor at Line n Column mm
^ is to separate the Prompt Text field and
<Command> is to instruct terminal to do certain things.
All the commands are listed as follow:
L, generating a low beep
M, generating a Medium beep
H, generating a High beep
A, Alphabetic data only which exclude
N, Numeric data only which include
0-9, +, -, /, ., ans *.
P, output Data field to the printer
Tnn, Max. length of input data
Kxx, Keyboard input timeout in
~ is to separate the Command field and Data field
<Data> will be displayed with Prompt and can be modified. Usually,
you send the default in the data field.
If there is a P in the Command
field, the terminal will send the Data to the serial printer.
<CR> is the carriage return.
