Programming Guide

Establishing Communication

The RL1 follows the

SCPI

(Standard Commands for Programmable Instruments) message-based

programming standard. It conforms to the

USBTMC

(USB Test and Measurement) standard.

USB

VISA

drivers are required for USB communication.

•

Alternatives:

National Instruments

Keysight

, etc.

Ethernet

Each RL1 is factory pre-set to use DHCP. To connect the RL1:

•

Connect the RL1 to the network via an Ethernet cable

•

Swipe on the front panel touchscreen to the

Setup

page to view the RL1

’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 is capable of controlling the RL1 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 below can be skipped if using JGR’s

CommunicationsLib.dll

(available upon

request).

Install

VISA

drivers on the development system

Connect the RL1 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
Components 5.11.0\Ivi.Visa.dll

Use the

IVI.Visa.GlobalResourceManager

to find all USB instruments on your system:
