Connecting Multiple Scanner

Up to 3 scanners can be connected to 1 cradle. When data is scanned (at the same

time) the cradle will sent the data from one scanner and then the date of the other

scanner. Different Prefix/Suffix per scanner will allow which scanner has sent the

data

If multiple scanners are connected to Host, in cradle-less mode, the data will/can

become mixed up (simultaneous scan).
