2.6.9 Service port connection
The service port (connector: SERVICE) allows to connect the valve to a RS232 port of a computer.
This requires a service cable and software from VAT. You can either use our freeware 'Control View', which can be
downloaded from www.vatvalve.com or purchase our 'Control Performance Analyzer'.
Alternatively the VAT Service Box 2 can be connected to the service port for setup and local operation.
The service port is not galvanic isolated. Therefore we recommend using this only for setup, testing and maintenance and
not for permanent control.
Refer also to «Local Operation» for details and to «Spare parts / Accessories» for ordering numbers of service cable,
software and Service Box 2.
Connector:
Use only screws with 4-40UNC thread for fastening the service port connector!
