Preparing for Automation
216 FTB-1v2 and FTB-1v2 Pro
The choice of a technology depends on your particular needs.
For more information on programming aspects, see the section on using
your product in an automated test environment.
Communication Characteristics
ActiveX (COM)  Allows you to develop an application that will run locally on your
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.
ActiveX (DCOM)
(Ethernet,
TCP/IP)
 Allows the sharing of network resources.
 Allows you to develop computer-based applications to directly
communicate with your unit.
RS-232
 Null-modem cable or USB to RS-232 adapter required to
establish connection between the computer and your unit.
 For increased speed and performance, run the application
locally on your unit through ActiveX instead of using RS-232.
Telnet and
Socket (Ethernet,
TCP/IP)
 Your unit can be directly connected to a Local Area Network
(LAN) or Wide Area Network (WAN) via its 10/100/1000 Base-T
interface.
 Allows the sharing of network resources.
 Allows you to develop computer-based applications very easily
to directly communicate with your unit.
 Telnet allows you to send SCPI commands over the Telnet
service.
 Socket allows you to send the same SCPI commands as you
would in Telnet, but without any formatting (raw
communication). The socket communication is similar to a
communication by RS-232, but over a LAN connection.
