To download events from the PowerVisa through the optical port, you must have the
following: a personal computer or laptop with Windows
®
operating system with either
RS232 serial port or network adapter, NodeLink
®
, and the appropriate Isolated
Communications Module assembly as described below.
The Isolated Communications Module assembly consists of two parts:
1. A fiber optic cable (P/N 900406) which connects the PowerVisa optical serial port to
the communication module;
2. The PowerVisa communication module which is available in three types:
• a 9-pin RS232 Communication Module (P/N COMM-RS232)
• a USB Communication Module (P/N COMM-OUA)
• an Ethernet Communication Module (P/N COMM-OEA)
The PowerVisa communication modules are optically isolated devices using infrared
light to transfer text and graphics to a computer running NodeLink
®
. These modules are
designed to connect the PowerVisa optical serial port to the appropriate interface -
either a standard RS232 serial port connector, USB adapter, or Ethernet adapter.
With NodeLink
®
you will be able to download data, upload or download instrument
setups, or view real time meter data from the PowerVisa. The downloaded data can be
viewed using the DranView
®
application.
Each adapter interface is supported using the computer’s standard serial ports.
