External Communication Interface

Isolated

Communications

Module

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.
