I'm trying to get this to work with a microcontroller as well. It works perfectly with the test software.
marin8703, if your ursart is 3.3V, you should be fine to connect it directly to that. Mine wasn't, so I had to connect it to an RS232 level converter chip.. i used the MAX3232.
To send the command to the scanner, is it ok if i send the packet in 'clumps'? Like first the header then the device address then type of packet etc? This is what I did, but I don't get a response from the scanner.
Anyone have any advice for those of us hooking it up to a microcontroller- like how to send and receive the commands?
edit: one more thing, is it ok that I have the powerEn connected to Vcc? It worked fine when connected to the computer, but just wondering if it'd affect it when connected to the microcontroller. Thanks!
