Baud rate
You have a choice of eight baud rates. The default is 600 baud. If you use the RS-232-C (V.24)
interface, you must take the load capacitance of cables longer than 15 m into account. If you
operate the CP 523 with an active TTY interface, a cable length of up to 10 m/33 ft. is possible.
With a passive TTY interface, cable lengths of up to 1000 m/3280 ft. are possible.
Longer cables can be implemented in general in conjunction with reduced baud rates.
Parity
You have a choice of five types of parity.
•
Even parity
The parity bit is set when the number of data bits with a value of "1" is uneven.
•
Odd parity
The parity bit is set when there is an even number of data bits with a value of "1".
•
Mark
The parity bit is always "1".
•
Space
The parity bit is always "0".
•
No parity check
The signal state of the parity bit is not significant. Parity is not checked when receiving;
however, the parity bit is always set to "1" when sending.
Even parity is the default.
BUSY signal
The BUSY signal is only relevant if you operate the module in Print mode without XON/XOFF
protocol.
The waiting times for "CR", "LF" and "FF" are not significant when evaluating the BUSY signal.
Interface
You can choose between the RS-232-C (V.24) and TTY interfaces here. See 2.3 for the characteris-
tics of the interfaces.
The TTY interface is the default.
Data format
Characters are transmitted between the CP and the peripheral device in a 10-bit or 11-bit charac-
ter frame. You can choose between seven and eight data bits within the character frame:
10-bit-character frame:
•
1 start bit, 7 data bits, 2 stop bits
•
1 start bit, 7 data bits, 1 parity bit, 1 stop bit
•
1 start bit, 8 data bits, 1 stop bit
11-bit-character frame:
•
1 start bit, 7 data bits, 1 parity bit, 2 stop bits
•
1 start bit, 8 data bits, 1 parity bit, 1 stop bit
•
1 start bit, 8 data bits, 2 stop bits
The default is an 11-bit character frame (1 start bit, 7 data bits, 1 parity bit, 2 stop bits).
