CALL 78 – Set Program
Port Baud Rate Purpose
Use CALL 78 to change the program port baud rate from its default value (1200
baud) to one of the following: 300, 600, 1200, 2400, 4800, 9600 or 19200 baud.
The default baud rate for the program port is 1200 baud if port PRT1 is
configured as the program port or 19200 baud if port DH485 is configured as the
program port. PUSH the desired baud rate and CALL 78. The program port
remains at this baud rate unless CALL 73 is invoked or the following conditions are
met:
•
The battery is dead or has been removed.
•
The battery-backup capacitor is discharged.
•
The EEPROM is removed or not programmed.
•
The power is cycled.
If this happens the baud rate defaults to 1200 baud.
