RS-232 Connection
This section shows the system configuration when a code reader CF26 and a programmable controller are connected with an
RS-232 connection.
RS-232
• Trigger commands are sent to a code reader from a serial communication module via RS-232 serial communication.
Character strings read by the code reader are received in a programmable controller via RS-232 serial communication.
• DMCC commands are sent from a serial communication module via RS-232 serial communication, and the read character
strings are registered in a code reader in advance.
The character strings of the read code are verified with the registered one. When they are matched, the read character
strings are received in a programmable controller via RS-232 serial communication. If they are not matched, the character
strings that represent a mismatch are also received in the programmable controller via RS-232 serial communication.
