Serial Configuration Mode
The IS4823/IS4825 can be configured by scanning configuration bar codes
the host device. With serial configuration, each command sent to the engine is the ASCII representation of
each numeral in the configuration bar code (see
[stx] and an ASCII [etx].
Example 1:
Feature
Disable Codabar
[ack]
If the command sent to the engine is valid, the engine will respond with an [ack].
[nak]
If the command sent to the engine is invalid, the engine will respond with a [nak] then automatically
exit serial configuration mode. All the settings chosen in the failed serial configuration session will be lost.
There is a 20-second window between commands. If a 60-second timeout occurs, the engine will
send a [nak].
Enter Serial Configuration Mode
To enter serial configuration mode, send the following command, [stx]999999[etx]. The engine will not scan
bar codes while in serial configuration mode.
Note: Serial configuration mode uses the current Baud Rate, Parity, Stop Bits and Data Bits settings that
are configured in the engine. The default settings of the engine are 9600 bits-per-second, space parity,
2 stop bits, 7 data bits, and no flow control. If a command is sent to the engine to change any of these
settings, the change will not take effect until after serial configuration mode is exited.
Exit Serial Configuration Mode
To exit serial configuration mode, send the following command, [stx]999999[etx]. The engine will respond
with an [ack].
