The USBTMC driver allows the device to be easily controlled using National Instruments Measurement and
Automation Explorer or an application built in the LabVIEW development software.
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.
All commands and queries through this port must be terminated with a Line Feed character.
*NOTE:
All firmware updates are done through the USB port.
2.10.5
Ethernet Communications
The Ethernet port allows remote control through a Transmission Control Protocol (TCP) data channel. The
default port for the TCP data channel is 10001.
By default, this port is set up to work on a network with a Dynamic Host Configuration Protocol (DHCP) server.
Upon connection to the network, 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.
*NOTE:
If connected to a DHCP network, the assigned IP address may be subject to change depending
on the network policy. Please contact your network administrator for more information about
how IP addresses are assigned and maintained.
If the connected network does not have DHCP enabled, then the device can be assigned an IP address using a
utility called DeviceInstaller™, downloaded from www.Lantronix.com. For assistance using this utility please
consult the embedded help file installed with the DeviceInstaller utility.
Once installed, the DeviceInstaller™ utility will scan the network and find all connected Lantronix Ethernet
devices. This list of found devices will include any connected AR Ethernet devices. By selecting one of the
connected devices from the list, its IP address and subnet mask can be changed along, with several other settings.
One should use caution when adjusting any unfamiliar settings as doing so may cause the port to become
unresponsive.
2.11 REMOTE COMMANDS
A typical command is made up of a key word and a parameter.
A space in a command or response will be indicated as
<space>
in subsequent definitions.
A vertical bar "
|
" dictates a choice of one element from a list. For example: <A|B> indicates that either A or B
can be selected, but not both.
Multiple commands cannot be concatenated within the same character string and any text appearing after a
termination character will be ignored by the control software.
Commands are case sensitive and should always be UPPER CASE.
All command and queries must be terminated with a Line Feed Character, indicated as
<LF>
in subsequent
definitions.
