[sci.electronics] Help with RS BarCode Reader

gregw@sugar.hackercorp.com (Greg White) (10/16/89)

Anyone have any experience or data using the Radio Shack BarCode
Reader on computers other than the Model 100 it was designed for?
I would especially like to get a pinout diagram of the connecter.
Can anyone help?

	The following is a *guess*, so use the information with caution.

	I believe that the Model 100 used an "industry standard" 9-pin
subminiature D-connector interface for a bar code wand.  Bar code wands
fall into three categories: (1) analog output; (2) digital output (NOT
decoded); and (3) "smart" with a serial decoded output.

	The analog output variety generally use a 5-pin DIN connector, and
the digital output variety generally use a 9-pin D-connector with the
following pinout and functions (as viewed by the wand):

	Pin 2	Wand output; a TTL line sunk to ground, usually with
		an open-collector transistor.

	Pin 7	Ground

	Pin 9	Supply voltage, usually +5 volts

	All other pins are unused.

	For further information, consult an H-P Optoelectronics Catalog
and look at the HEDS-3000 digital bar code wand.

	Bear in mind that I *believe* that the Model 100 uses the above
digital wand interface, but that I am not 100% certain.

What Larry Lipman said is exactly right... The pinout is industry standard...
Quoted from the standard model 100 manual (now that I'm becoming an expert
on the model 100 :--) ):

	PIN	Symbol	Description
	 1	  NC	
	 2	 RxDB	Receive data from bar code reader
	 3	  NC	
	 4	  NC
	 5	  GND	Ground
	 6	  NC
	 7	  GND	Ground
	 8	  NC
	 9	  VDD	+5

I have never used the bar code reader, though. I know Radio Shack publishes
programs in bar code format. 

I have the standard manual, and the Tech Ref manual, complete with
schematics, and theory, if you need to ask any questions...

Cheers!
