CHANGING THE BAUD RATE AND PARITY

The baud rate and parity of the DATUM 2000™ Serial Option can be set to

the following values:

COMMAND ASCII

BAUD: 300 3 33H

600 6 36H

1200 1 31H

2400 2 32H

4800 4 34H

9600 9 39H

PARITY: NONE N 4EH

ODD O 4FH

EVEN E 45H

To change the baud or parity, transmit a P, ASCII 50H, and the command

number or letter from the table above. For example, to set the DATUM

2000™ to 9600 baud and even parity, transmit P (always allow 1 second

between commands sent to DATUM 2000™) and then transmit 9, to set the

baud rate to 9600. Set your computer or terminal to 9600 baud and then

transmit P and E to set even parity.

When you change the communications parameters, they are stored internally

and will be recalled every time the DATUM 2000™ is powered up.

Hint: Transmit a V to the DATUM 2000, if the verify message "SETRA

DATUM 2000", is not received, wait 1 second, and retransmit a V. Transmit

a V each second until the verification message is received. When the

verification message is received, the DATUM 2000™ is ready for a new

command. Now transmit a P, wait at least 1 second and transmit the baud or

parity parameter.
