1-4 Remote Programming Setup and Interface
LMR Master LAN Connections
The RJ45 connector is used to connect the LMR Master to a local area network. Integrated
into this connector are two LEDs. The amber LED indicates the presence of LAN voltages (a
live LAN connection) while the green LED flashes to show that LAN traffic is present. The
instrument IP address is set by pressing the Shift key, then the System (8) key followed by
the System Options soft key and the Ethernet Config soft key. The instrument IP address can
be set automatically using DHCP, or manually by entering the desired IP address, gateway
address and subnet mask.
An active Ethernet cable must be connected to the LMR Master before it is turned
ON in order to enable the Ethernet port for DHCP or for a static IP address.
Depending upon local conditions, the port may remain enabled when changing
Note from DHCP to static IP address, when changing from static IP address to DHCP,
or when temporarily disconnecting the Ethernet cable.
If the port becomes disabled, ensure that an active Ethernet cable is attached to
the LMR Master and then cycle the power OFF and back ON.
Dynamic Host Configuration Protocol (DHCP) is an Internet protocol that automates the
process of setting IP addresses for devices that use TCP/IP, and is the most common method
of configuring a device for network use. To determine if a network is set up for DHCP, connect
the LMR Master to the network and select DHCP protocol in the Ethernet Config menu.
Power cycle the LMR Master. If the network is set up for DHCP, then the assigned IP address
should be displayed briefly after the power-up sequence.
To display the IP address of the instrument, press the Shift key, then the System (8) key,
then the System Options soft key and the Ethernet Config soft key.
USB Interface Connection and Setup
For proper detection, Master Software Tools must be installed on the PC prior to
Note connecting to the S412E using the USB port. Master Software Tools provides the
installation tools to install the USB and VISA drivers.
The Universal Serial Bus (USB) architecture is a high-performance networking standard that
is considered "plug and play" compatible. The USB driver software is automatically detected
and configured by the operating system of the devices that are connected to the bus. The
S412E conforms to the USB 2.0 standard and is a USB "full-speed" device that supports data
rates of up to 10 Mbps with the following restrictions:
• One USB network can support up to 127 devices
• The maximum length of USB cables between active devices is 5 meters (for USB 2.0)
and 3 meters (for USB 1.0)
To run the following example, you must have NI-VISA 2.5 or later installed on the controller
PC, and you must select the VISA library (visa32.dll) as a reference in a Visual Basic project.
For remote USB control, the controlling PC needs to have a version of VISA installed that
supports USBTMC (USB Test and Measurement Class) devices.
