84 Electronic Data Transfer via Network Connection
13. Electronic Data Transfer via
Network Connection
13.1 Network Concept The network solution for the Sartocheck
®
4 plus Filter tester incorporates the TCP-IP
and FTP protocol standards, with data being transmitted via the Ethernet standard.
FTP uses the passive mode, that exclusively establishes one single TCP con nection.
Additional information:
t Electronic records are transmitted in ASCII (or if selected PDF) format, with an
appropriate checksum (CRC).
t Sartocheck
®
4 plus is the communication master. All data transfer (import or
export) must originate from the Sartocheck
®
4 plus.
t Inside the Sartocheck
®
4 plus, an FTP-client program is running, which actively
transmits the electronic records to and from the server PC.
t Inside the server PC, an FTP-server program is running, which passively receives
the electronic records from the Sartocheck
®
4 plus or provides them to the
Sartocheck
®
4 plus.
t One server PC (with FTP-server) can serve one or more Sartocheck
®
4 plus’s.
t One or more local PC’s can use the file share.
The following diagram describes the architecture and data flow:
