Barcode reader - via RF
Archiver
Posts: 46,084
Hello,
I'm trying to figure out if this is even possible using the BASIC
stamp.
Hardware involved:
Barcode reader
RF transmitter & receiver
Relay
etc.
Simply put: I want to have a barcode read, sent via RF, received and
inputted into a PC. If the barcode is valid, send a signal back to
the stamp and have it engage the relay.
Am I asking for too much, or is this something the BASIC stamp can do?
Any good leads for me? [noparse]:)[/noparse]
Thanks,
-CC

We have an example application using Bluetooth compatible 2.4GHz ISM modules
with a magnetic card reader. They essentially replace the need for a serial
cable. In essence its the same as with a barcode reader:
www.trcontrolsolutions.com click on examples and its under the HandyPort
section. You could then use pairing wireless modules to send data back to
the BS.
So its all possible!

Should be do-able. I have used the RF units available at Rentron. I have
never used a barcoder, but I know it can be done. You will need a Stamp at
both ends. One thing if this is for a security feature, it could be fooled
by an outside RF signal. You could protect tgis by using an algorithm of
some sort to encode the data.

Thanks for your input - it is used for access control; already have a
pretty good idea of how I want to encode the data.
Will have to checkout those RF units.
Thanks again,

Depending on how many different barcodes you have to decode, you
can do most of it right in the stamp ( use bsx if you need more
room ).
Unless there's a particular reason to have the stamp remote from
the barcode scanner, you can integrate the whole thing at the point
of use.
I have some sample code for a card reader application where I
kept a couple hundred codes on the stamp and triggered one of several
actions depending on which card was read. Just e-mail me direct if
you're interested.

You can avoid using two stamps for this project, by using an
EmbeddedBlue eb500 module to communicate via Bluetooth to a PC with
a standard Bluetooth USB dongle. The stamp would be connected to the
barcode reader, the eb500, and your physical relay. When the barcode
reads a value, the stamp would transmit it to the PC via the eb500.
the PC would process the data and send a valid or invalid response
back to the stamp. The stamp would then switch the relay on or off
depending on the data received.
I am not sure what your project requirements are, but by using a
standard RF format like Bluetooth you gain a lot of flexibility. You
could easily change your barcode database lookup server from a PC,
to a Mac, a PDA, a phone, another stamp, etc. without making any
changes to the scanner device.
