You can install the scanner with the USB interface cable to work with either PC
or iMac USB port. See Figure 1.1 for reference. Your operating system may
require the original setup CD to install the driver with initial setup.
Installed as an USB Interface
The factory default setting should work with either PC or iMac USB interface; you may
also scan the following label to make sure you get the right device setting.
Operating Parameters
There are some operating parameters that can be configured to work for
different applications.
Intercharacter Delay
Intercharacter delay is the time period that the scanner will wait before
transmitting the next character after the first character was sent. If data sent by
the scanner was incorrect or missing characters, a longer intercharacter
delay may solve the problem.
Interblock Delay
lnterblock delay is the minimum time interval between two adjacent scanning.
If the processing speed of your host device is slower than your scanning
speed, a longer interbIock delay may ensure the data integrity.
