Interface Parameters - Siemens SIMATIC Ident RF200 Operating Manual

1.2

Interface parameters

You can select the following interface parameters:
● Transmission speed:
– 19.2 kBd (default),
– 57.6 kBd,
– 115.2 kBd
● Parity:
– without,
– even,
– odd (default)
● Stop bits:
– 1 (default),
– 2
The reader stores these parameters retentively. You can modify these parameters using the
"SET RS232" command and read them out using the "SLG-STATUS" command.
NOTICE
Documenting changes to the interface parameters
Document all changes that you make to the interface parameters. You can only read out
data when the interface parameters set in the driver and on the reader match.
If you cannot use the reader with the default settings, follow the steps below to change
settings of the serial interface:
1. Connect the reader to a PC.
2. Send the interface frame "SET RS232" using a standard PC tool (e.g. HyperTerminal).
The reader can then be deployed in the target environment.
Note
Run "SET-RS232" before the first "RESET"
To change the interface parameters, the "SET RS-232" command must be sent before the
first "RESET" command. The acknowledgement of the command is still made with the
original interface parameters; following this the reader is ready for operation with the new
parameters.
Make sure that you perform this procedure when necessary with all readers since all readers
ship with the default transmission speed 19.2 kBd.
