12 Rev A
A glass, multi-mode, fiber-optic cable of 200um is recommended, however fiber-optic cable as small as 50um
can be used. The connector type for this port is ST.
This port can be used in conjunction with either an AR model IF7000 RS-232 to Fiber-Optic Interface (1200
to 9600 baud only) or an AR model IF7001 USB to Fiber-Optic Interface (19200 baud only). Note that these
devices use SMA connectors so a fiber-optic cable is needed with ST connectors on one end and SMA
connectors on the other. This cable can be obtained from a fiber-optic cable distributor such as Fiber
Instrument Sales (FIS). Their web-site can be found at www.fiberinstrumentsales.com . An example cable
that will work for this connection is FIS Part Number D615M7FIS. The 7 in the part number refers to the
length of the cable. In this case the length is 7 meters.

2.4.4 USB Communication
The USB port is a USB 2.0 port. It also complies with the USB Test and Measurement Class (USBTMC)
Standard. Communications with this port requires the host computer to have a USBTMC driver available.
All commands and queries through this port must be terminated with a Line Feed character.
The cable required to make this connection is a USB 2.0 A-B peripheral device cable. The cable can be no
longer than 5 meters. If a longer distance is required a USB hub must be used. A cable carrying the official
USB logo is recommended.
When connected to a PC running Windows 2000 or XP a window will pop-up labeled Hardware Wizard. If
this PC has National Instruments LabView installed it will have a USBTMC driver that will work with this
port. This driver will allow the device to be easily controlled using National Instruments Measurement and
Automation Explorer or LabView. It should be noted that the USBTMC driver provided by National
Instruments is a Virtual Instrument Software Architecture (VISA) driver which can be used with other
programming languages besides LabView. For more information on this please consult the National
Instruments Website found at www.ni.com .
NOTE: All firmware updates are done through the USB port.
2.4.5 Ethernet Communication
The Ethernet port allows remote control through a Transmission Control Protocol (TCP) data channel. All
commands and queries through this port must be terminated with a Line Feed character.
By default this port is setup to work on a network with a Dynamic Host Configuration Protocol (DHCP)
server. Upon connection, an Internet Protocol (IP) address is assigned based on the internal Media Access
Control (MAC) address. The MAC address is printed on a label located near the Ethernet port.
