External Communication Interface

Isolated

Communications

Module

To download events from the 4400 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 4400 optical serial port to the

communication module;

2. The 4400 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 4400 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 4400 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 4400. The downloaded data can be

viewed using the DranView

application.

Each adapter interface is supported using the computer’s standard serial ports.
