I have an idea to use a wireless bar-code scanner to scan bar code pairs into an OI table.
I came across a 100m range scanner which would be perfect, but it's pc interface end bluetooh@wireless started talking about comms port setup, I was hoping for some keyboard wedge answer,
Anyway, has anyone done this before: - found a suitable device ; listen to comport port from oi; other solutions./setup
There's enough examples out there in VB - just prototype the functions from the DLL and work from there.
I use several Motorola DS6878-HC wireless scanners and they work very well, although the distances involved are considerably less than 100m.
Barry,
You can use standard microsoft mmcom ocx and construct a 'listener' which - on event - looks at the com port and grabs a chunk amd assembles strings to pass.
I did this yonks ago for a sports timing system. Its rather crude but works without hitch.
There are more sophisticated and better ways - I know that Mike Ruane at one stage was investigating; the challenge is that a lot of these kind of devices are now usb or tcp/ip interface and that requires another quantum of understanding - the likes that only emu's can comprehend.
How did you receive the data that was transmitted - online docs are a bit vague - but I now have a suspicion that there is a wireless usb 'keyboard wedge' available.
The DS6878-HC scanners do operate as wireless usb keyboard wedges
Thank you. I am now starting to see that.
