Character Format
5.3.3
The data characters are transferred in the format shown below. A party bit is added to every character
so that the total number of 1’s in the data bits, together with the parity bit, is odd for odd parity and
even for even parity.
The following commands are provided to set the number of data bits, type of parity bit and the number
of stop bits. The Z2 command (save settings in non-volatile memory) needs be used after these
commands to activate and save the new configuration.
