EPICS Demo Burkhard Kolb and Peter Zumbruch

Outline Check connection details – Hardware manual Test/Debug command – Try simple command/response in text form Select commands to implement – Hardware manual Some examples – Set and read voltage/ formatted parsing

Connection details Check manual for information on: – RS223 parameters (baud, parity…) – TCP/IP name, port number – Command delimiters

Extract from manual From the Agilent N5700 manual:
