RS232 setup
The RS232 setup menu consists of two setup issues:
•
RS232 baudrate
•
RS232 mode
RS232 baudrate
The “RS232 baudrate” determines the bit rate of the
communication between the CU and an external
unit connected via the RS232 or RS422 connection.
Values: {2400, 4800, 9600, 19200, 38400, 57600,
115200}
RS232 mode
The “Input mode” defines whether the ASCII
communication via RS232/RS422 is protected by
CRC check or not.
By protecting the communication (“Protected”), the
risk of faulty communication via RS232/RS422 is
minimized.
The risk of faults via RS232/RS422 is higher
running the “Default” mode; however, the
communication is possible from standard interfaces.
The RS232 terminal interface emulator, Tera Term,
does not feature the possibility of guarding the
ASCII communication by CRC check.
Values: {Default, Protected}
Security setup
The setup determines if ”Audio Scrambling” is
activates or not.
Values: {Off, On}
Default value is ‘off’. When switching to ‘on’, the
CU has to be restarted. All units will automatically
change to the scrambled mode.
The scrambling mode is used in high security
places, when ears dropping cannot be accepted.
Configuration
The “Configuration” menu comprises three menu
items:
•
Load configuration
•
Save configuration
•
