INTRODUCTION • HOW IS THE MX009 CONFIGURED FOR USB KEYBOARD EMULATION?
This guide contains the configuration bar codes necessary to ensure that the 
scanner communicates properly with the MX009.  The scanner 
communicates using RS232 protocol.  The default (RS232) settings of the 
scanner are as follows: 
• For Non-PowerLink Scanners 
9600 baud, 7 data bits, 2 stop bits and space parity 
• For PowerLink Scanners 
9600 baud, 8 data bits, 1 stop bits and no parity 
In addition, the scanner uses ACK/NAK and XON/XOFF software 
handshaking, and the data transmission ends with both carriage return and 
line feed suffixes. 
On non-PowerLink scanners, the 1st and 2nd prefixes are used to set the 
country of the keyboard.   
NOTE #1 
Please note, some of the older Metrologic products allow for a maximum 
of 2 prefixes.  Because 2 prefixes are required for setting the country, 
custom prefixes cannot be set on these products.  Please refer to the 
scanner configuration guide for the number of configurable prefixes 
available on your product. 
Example #1:  MS951, German Keyboard, Bar Code = 012345, No custom 
prefixes available. 
Configuration:    <Ctl-V>  <D>  <012345>  <CR><LF> 
 Pref #1  Pref #2  Data  Terminators 
Data Transmitted = 012345<CR> 
Prefixes #1 and #2 specify the German keyboard and the <CR> <LF> 
terminators are needed by the MX009 for framing the data.  Only 2 custom 
prefixes are available on the MS951*, MS6720, MS700, MS860, Tech 
Series, IS4120* and IS4220*.
