Menu button or Enter button leaves this screen.

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

∙Delete configuration

Load configuration

The “Load configuration” item brings the user to the Load configuration confirmation display:

This will overwrite
