7.10.5.3Baud Rate - P712

The speed of transfer of the interface in bit/s. The default value of this parameter should not be changed. The parameter is included in the menu system for future software updates. Default = 9600

7.10.5.4Start Bits - P713

The number of start bits. The default value of this parameter should not be changed. The parameter is included in the menu system for future software updates. Default = 1

7.10.5.5Data Bits - P714

The number of data bits between start and parity bit. The default value of this parameter should not be changed. The parameter is included in the menu system for future software updates. Default = 8

7.10.5.6Parity - P715

Whether an even or odd parity check bit has been added. The default value of this parameter should not be changed. The parameter is included in the menu system for future software updates. Default = even

7.10.5.7Stop Bits - P716
