LDD100 Operating Instructions

Thereafter, the RTS line must be switched with a period of approximately 200ms,
independent of all other communication. Delay of this switching will result in abortion of the
communication connection.
11.2 Parameter Upload
The parameter set has to be uploaded before any current pulse may be generated.
In the upload process all data is send byte by byte. After receiving one byte the device returns
the received byte (echo). Following verification, the next byte can be send. An error in data
transfer can be realized in this manner.
Note that all data must be uploaded in the order described, even if not all parameters are used
in an operating mode. The general data upload starts with “@P”.

The repetition range depends on clock parameter.
22
The pulse width depends on this parameter and clock parameter as well (s. section: clock
parameters).

200A is just an example. The real value depends on the LDD type.
