CONFIGURATION MODES  
 
The MS9500 Voyager has three modes of configuration. 
 
•  Bar Codes  
The MS7120 can be configured by scanning the bar codes located in the 
MetroSelect Single-Line Configuration Guide.  This manual is available for 
download at www.honeywellaidc.com. 
 
•  MetroSet2 
This user-friendly Windows
®
 
-based configuration program allows you to 
simply ‘point-and-click’ at the desired scanner options.  MetroSet2 is 
available for download at www.honeywellaidc.com. 
•  Serial Configuration 
This mode of configuration is ideal for OEM applications.  Serial 
programming mode gives the end-user the ability to send a series of 
commands using the serial port of the host system.  The commands are 
equivalent to the numerical values of the bar codes located in the 
MetroSelect Configuration Guide. 
 
How does Serial Configuration work? 
 
1.  Each command sent to the scanner is the ASCII representation of each 
numeral in the configuration bar code.  The entire numeric string is framed 
with an ASCII [stx] and an ASCII [etx]. 
 
EXAMPLE #1
Command for Disabling Codabar 
:  
Command = [stx]100104[etx] 
String Sent to Scanner = 02h 31h 30h 30h 31h 30h 34h 03h 
(All values are hexadecimal). 
 
2.  If the command sent to the scanner is valid, the scanner will respond with an 
[ack]. 
 
3.  If the command sent to the scanner in invalid, the scanner will respond with 
a [nak]. 
 
NOTE:  If this occurs, the end-user must start over at the very beginning of 
the configuration sequence.  Re-transmitting the invalid command 
will not work, the user must start over.
