Keysight

, etc.

Ethernet

Each BR1 is factory pre-set to use DHCP. To connect the BR1:

•

Connect the BR1 to the network via an Ethernet cable

•

Swipe on the front panel touchscreen to the

Setup

page to view the BR1

’s

IP address

The TCP/IP libraries provided by most operating systems are sufficient. JGR Optics can provide a
communications library upon request.

Note: any

VISA

implementation can control the BR1 via TCP/IP.

Step-by-step Guide

This section will provide a step-by-step programming guide in a

.NET

programming environment such as

VB.NET

. Steps 3-5 be

low can be skipped if using JGR’s

CommunicationsLib.dll

(available upon

request).

Install

VISA

drivers on the development system

Connect the BR1 via its USB B port to the development system

Add a reference to

Ivi.Visa.dll

in your project:

C:\Program Files (x86)\IVI Foundation\VISA\Microsoft.NET\Framework32\v2.0.50727\VISA.NET Shared
