3. Installation
3.1 Connecting the keyboard
The ATB422/423 keyboard has a single cable, terminated with a “Y” adapter comprising a USB
plug and an inline coaxial power connector.
The USB plug may be connected to any available powered USB port on the host PC.
The coaxial power connector is only required if an external barcode reader (for example, the
Access LSR120) is connected to the Auxiliary Serial Port of the keyboard. It may be connected to a
5V >500mA regulated power supply, or it may be connected to a spare powered USB port on the
host PC using an Access
“USB Power Stealer” cable, part number 5KBD133402.
The keyboard, and the mouse (if fitted), will be recognised as plug-and-play keyboard and mouse
respectively.
3.2 Installing and configuring the driver
The Access Serial Port Driver must be installed in order to read data from the OCR (if fitted), the
MSR (if fitted) and the Auxiliary Serial Port (if fitted). This driver may be found on the Access Ltd
website at the following URL:
Visit the Access Website Downloads Page
http://downloads.access-is.com/
and Click on ATB422/423 Driver
You will be prompted to either run the installation immediately from the
website, or to save the .MSI file to your hard disk for offline installation
at a later date.
Both options are valid. The remaining instructions are based on the
assumption that you install immediately.
