INTRODUCTION Metrologic’s MX009 USB Cable is a device that converts serial RS232 formatted 
data to either USB Keyboard or USB Serial communication protocol.  The MX009 
can be used with all Metrologic products equipped with an RS232 interface, as 
well as all versions of Metrologic PowerLink compatible scanners.   
  All versions of Metrologic’s PowerLink compatible scanners are equipped 
with RS232 transmit and receive communication lines. 
• HOW DOES THE MX009 USB CABLE OPERATE?
The scanner transmits scanned data via RS232 communication to the 
MX009.  The MX009 then converts the data from RS232 to either USB 
Keyboard or USB Serial data.  The MX009 will only function with Metrologic 
scanners that are equipped with RS232 communication capabilities.   All 
PowerLink compatible scanners are equipped with the ability to 
communicate RS232 independent of the interface purchased.  For a list of 
Metrologic PowerLink compatible scanners, refer to page 5. 
  Some older Metrologic scanners may not be used with an MX009 
since they have only one interface available.  For example, the 
MS951 with OCIA interface will not function with an MX009 
because it does not have RS232 capabilities. 
• WHAT IS THE DIFFERENCE BETWEEN
USB KEYBOARD EMULATION AND USB SERIAL EMULATION?
When the MX009 is set-up for Keyboard Emulation, the scanned data will 
appear in the active PC application as if the keys were pressed on the PC’s 
keyboard. 
When the MX009 is set-up to communicate as a USB Serial device, the data 
emulates serial (RS232) data through the use of a Metrologic developed 
driver.  The device will then work with existing serial (RS232) applications.   
The drivers can be downloaded at:

For Windows 98 (Second Edition) Operating System

The MX009 leaves the factory set for either USB Keyboard Emulation or 
USB Serial Emulation.  Refer to pages 8 - 18 of this manual to determine the 
set-up of your MX009.
