Using Reader Commands
After the CN2B Computer is connected to your network, you can send the
CN2B Computer a reader command from an application to perform a task,
such as changing the time and date. Some reader commands temporarily
override configuration settings and some change the configuration settings.
Change Configuration
The Change Configuration command must precede any configuration
command. If you enter a valid string, the CN2B Computer configuration is
modified and the computer emits a high beep. To send the Change Config-
uration command through the network, use the $+ [command] syntax
where command is the two-letter command syntax for the configuration
command followed by the value to be set for that command.
You can also make changes to several different commands by using the
$+ [command]...[command n] syntax. There are seven configuration
command settings that you can change in this way. See each command for
information on respective acceptable “data” values.
Command Syntax
Audio Volume BVdata
Automatic Shutoff EZdata
Backlight Timeout DFdata

Example 1
To change the Beep Volume to Off, you can send this string to the CN2B
Computer through the network: $+BV0
where:
$+ Indicates Change Configuration.
BV Specifies the Audio Volume parameter.
0 Specifies a value of Off.
Example 2
To change the Beep Volume to Very Quiet and the Virtual Wedge Grid to
123:
