Wireless Barcode Reader

[cuber18]

does anyone have an idea on its circuit schematic.. we have a barcode reader and we also have a transceiver..

What reader do you have? Does it have a serial output? Its fairly straightforward if it does.

And what transceiver do you have? More information would help.

i have ps/2 barcode.. and my transceiver is UART capable.. it has 6 channels with the range of 200meters.. how can i interface it with a microcontroller?

the PC2 interface has, apart from ground and Vcc, DATA and CLOCK signals which you can connect two digital input lines of a microcontroller.
You wait for a START bit on the data line, then read the data line as the information is clocked in. Have a look at


you then connect the RF device to a UART for transmission of the information.

thank you for the reply.. you have any schematics or any references to support our project? thank you sir

if you have a look at page 27 of the EasydsPIC2 manual it shows the wireing of the PS/2 connector and connection to a micro

the micro is dsPIC but you could connect it to any micro with two spare digital input pins.

you should be able to connect the RF device to the UART Tx and Rx pin of the micro (check that logic levels match)

Take a look at PS/2 barcode reader to RS232 port - need help and the linked Simple AT Keyboard Interface V1.04 for Microchip PIC16F84 Microcontroller
