A HOST CONFIGURATION STRINGS
In this section we provide a description of how to modify the device configuration
using serial strings sent from the Host.
This method requires the RS-232 interface.
NOTE
The device configuration can be changed by receiving commands from the Host
through the serial interface. When this method is used, the programming sequence
format is the following:
Command
Character sequence in following tables
CR $-
$+
Carriage return character (0D Hex)
Enter configuration environment
Exit and Save configuration
Example:
Beeper tone 1
Beeper low intensity
BG1 $- CR
Carriage return character (0D Hex
)
Exit and save new configuration
AC410132BH0
Matrix 2/5 3 bars: no check digit,
variable length code from 1 to 32 characters
$+
Enter configuration environment
Multiple command programming sequence:
Each configuration parameter setting removes the condition previously active for
that parameter.
The device buffer can contain about 400 characters. If your programming
string goes over this value, you must split it into separate groups and send
each group after a delay of at least 3 seconds to give the reader time to empty
the buffer and interpret the commands.
