Overview 
 
The MS837 has been factory configured with a set of default parameters. Since many host 
systems have unique formats and protocol requirements, the MS837 provides a wide range of 
configurable features that may be selected using the programming bar codes included in this 
reference guide. Once the configuration is completed, the MS837 stores the settings in 
nonvolatile memory (NOVRAM). NOVRAM saves the settings when the power is off. 
Note:  Bar code descriptions marked with an asterisk ( * ) define a feature that is a factory 
default. Bar codes marked with a tilde ( ~ ) require the Multi-Code configuration method.
