7.1 Definition of the communication interface
Generic Interface for tico 77x
General:
Explanation of the term “Generic Interface”
The generic interface provides basic functions for reading/writing counter
values and function settings to/from the counter. An ASCII protocol is used for
communication, but other, higher protocols can be set. This documentation
describes the functionality of the generic interface between the counter and
the interface PCB.
Following is only an overview of the generic interface. For detailed view, please
visit our webpage www.hengstler.com or www.tico-counter.com.
Hardware protocol:
The generic interface is based on RS232.
Baud rate: 38.4 kBd
Bits: 8
Parity: even
Stop bits: 1
Software protocol:
The generic interface between tico77x and the interface PCB is based on ASCII
commands and data values in ASCII format.
The internal counter structure of the values is binary and optimized for high
counting speeds. The values exchanged via the generic interface are ASCII
values. The counter converts the values into its internal format.
