Electronic Instrumentation CAEN HV Wrapper CAEN HV Wrapper is a library, available either as a set of ANSI C functions or LabVIEW™ VI’s. Such set provides the software developer an unified software interface for the control of CAEN Power Supplies.
The module is provided with a USB2.0 compliant interface and Ethernet Port (TCP/IP). For link connection, refer to instructions given at page 10. CAEN provides the CAEN GECO2020 Control Software that allows a friendly remote management of all Unit’s functional parameters (see www.caen.it software support page); anyway, the connection can be performed also via VT emulators, we suggest to use Tera Term (see https://ttssh2.osdn.jp/index.html.en)
