 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 scanner.

Printer Support
RF-2900 supports most of the RS-232 interfaced printers to generate labels, tickets, or receipts.

Prompt/Command Format
Host sends the Prompt/command string to the RF-2900 as:

       <SOT>n M <Prompt> ^ <Command> ~ <Data>< CR> 

       <SOT> is ASCII 2. 

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.

      @C0              Clear entire screen
      @Cn              Clear Line n
      @nMessage      Display Message on Line n
      @Pnmm          Position the cursor at Line n Column mm

 ^ is to separate the Prompt Text field and Command field
<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 0-9.
                        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 xx second
~ 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.

RF2300 RF Reader


  • Remote bar code scanning
  • RF range up to 300 ft
  • Uses Wand, CCD, Laser, or RS-232 interfaced device.
  • One Base Unit controls up to 8 readers
  • Base Unit attaches to PC, RS-232 or USB.
  • 900MHz, Spread spectrum, frequency hopping. No interference with other RF equipments.
  • 16 selectable channels.  Up to 16 Base Units, 128 readers in the same area.

RF-2300  is a wireless bar code  reader which provides an affordable alternative to conventional cabled scanner. 

You may have any type of bar code scanner - Wand, CCD, Laser, undecoded, or RS-232 interfaced, plugged into this compact and battery operated product.  Then you can scan bar code labels remotely from your host computer up to 300 ft. It operates at the license free band -900 Mhz, and it’s FCC certified.

Instead of spending a fortune to purchase a wireless scanning system, you may easily upgrade your current bar code scanner to a wireless system with the RF-2300; simply plug the undecoded or RS-232 interfaced scanner into the RF-2300 reader and get ready to scan.

One Base Unit  can receive data from up to 8 RF-2300 Readers and each reader can be set with different ID.  The base unit can send data to the host computer via keyboard wedge, USB port,  RS-232 port, or even RS-232 serial wedge.

It is a two way wireless system - a confirmation will be sent back to the reader from the base unit when a data is successfully received and sent  to the host computer.

The RF-2300 is operated with 3 standard AA battery.  You may use any type of AA battery - Alkaline, Ni-CAD or Ni-HM.  This feature makes the operation so easy and flexible: when battery is low, simply replace the batteries and charge the low batteries with a inexpensive and off-the-shelf battery charger.

This wireless product is very useful to increase productivity in many applications:

In factory or warehouse applications where the cable restricts movement and wireless scanning is simply a better solution.

In harsh environments where the cable can be damaged and make your scanner system inoperable.

In retail environments where a cabled scanner limits access outside of the counter area and heavy, oversized or bulk items are difficult to bring to the counter for checkout.

In shipping and receiving applications where the cable denies access. 

With a molded holder, the RF-2300 can be
piggybacked with a PSC6000 laser scanner
to make them as an integrated unit for one
hand operation.
