Parameters for the serial interface (parameter block 0)
• 2400 baud
• Even parity
• No BUSY system
• V.24 (RS 232C) interface
• 7 data bits (11-bit character frame)
• Handshake OFF

** FB 99 waits until the CP 523 can accept job requests ( 4.1)
Note:
Restart OB 22 is processed only when the CPU is at RUN before switching from "POWER OFF" to
"POWER ON".
Note:
The status byte can be scanned approx. 30 ms after issuing the job request to check on whether
correct parameter values were forwarded (X4 is returned to indicate false values ( 7.4.1)).
