EXFO IQS-600 Integrated Qualification System - Manual (Page 131)

Preparing for Automation
Integrated Qualification System 123
Control Technology Characteristics
Local ActiveX (COM)

Allows you to develop an application that will run
locally on the IQS controller unit within Windows

Best approach when speed is your top priority (no
physical connection that slows down the
process)

Supported by most development software

Lower cost
Remote ActiveX (DCOM)
(Ethernet,
TCP/IP)

IQS controller unit can be directly connected to a
Local Area Network (LAN) or Wide Area Network
(WAN) via its 10/100/1000 Base-T interface

No need for a GPIB card

Allows the sharing of network resources

Allows you to develop computer-based
applications to directly communicate with the IQS
controller unit
Remote GPIB

IQS controller unit must be equipped with the
GPIB option

IQS controller unit can be used as a device in a
GPIB chain (it meets the IEEE 488.2 standard)

A single GPIB address allows you to control up to
100 logical optical instruments

Most commonly used interface to simultaneously
control many instruments
Remote RS-232

Null-modem cable required to establish
connection between the computer and the IQS
controller unit

For increased speed and performance, run the
application locally on the IQS controller
unitthrough ActiveX instead of using RS-232
