18 — RS-232 DCM
Procedure 18-5 To set RS-232 DCM control signals
Selecting ON or OFF for inputs configures them as ASSUMED_ON or ASSUMED_OFF.
Selecting ON or OFF for outputs configures them as FORCED_ON or FORCED_OFF.

Data structure (asynchronous only)

The data structure of asynchronous transmission has three configurable
characteristics:
•
character length
•
number of stop bits
•
type of parity
Character length
Character length is the number of data bits used to transmit a character in
asynchronous transmission. Character length can be set to:
•
5 bits
•
6 bits
•
7 bits
•
8 bits (default)

A character must be 8, 9, 10 or 11 bits. The number of bits
Note —
in a character is the sum of the start bit (always 1), character length (5,
6, 7 or 8), stop bits (1 or 2) and parity bit (0 for no parity or 1 for odd,
even, mark or space). For example, if the character length is set to
5 bits and the number of stop bits is set to 1, the parity cannot be set
to no parity. If this rule is broken, the relevant softkeys are not
displayed.
