SRS Labs SR1 Manual

Setup SR1 to Connect to a Remote PC over
Ethernet
SR1 provides a method for communication to a remote computer using the VXI-11
protocol over Ethernet.
To perform this test, you need the following:
 An SR1 connected to your local area network with a suitable Ethernet cable
 A Windows PC connected to your local area network with a suitable Ethernet
cable
 The PC must have NI MAX and VISA drivers installed. To obtain the right
software and drivers, consult National Instruments webpage at ni.com.
SR1 TCP/IP Setup
After you have started your SR1, you should configure its local area network properties.
Follow these steps to set those properties:
On SR1:
 In the Main Menu, select Tools -> Networking -> Network Setup
 In the new window, double click on 'Local Area Connection'
 In the new window, click the 'Properties' button
 Scroll down the list and click to select 'Internet Protocol (TCP/IP)'
 Click on the 'Properties' button
At this point, if your local area network has a DHCP server which assigns IP addresses,
you can try the following:
 Click on the 'Obtain IP Address Automatically' radio button
 Click on the 'Obtain DNS Server Address Automatically' radio button
 Click 'OK'
After about one minute, the DHCP server should assign an IP address to your SR1. You
can find the IP address here:
 Click on the window titled 'Local Area Connection'. It should already be open
from the previous steps.
 Click on the 'Support' tab.

 Copy down the IP address that has been assigned.
If DHCP service is not available, then you must assign an IP manually:
 Click on the Local Area Connection Properties' Window. It should already be
open from the previous steps.
 From the list, select 'Internet Protocol (TCP/IP)'
 Click on the 'Properties' button
 Click on the 'Use the following IP Address' radio button
 Click on the 'Use the following DNS Server addresses' radio button
 Enter an IP address, subnet mask, gateway and DNS Server addresses that are
suitable and are defined for your local network. You should contact your network
administrator for those values.
 Click 'OK'
Enable VXI-11 on SR1
Now we will enable the VXI-11 interface on your SR1:
 From the SR1 application, select from the Main Menu: Tools -> Preferences
 Click the Remote tab on the top of the window.
 On the bottom of that window tab, click on the VXI-11 tab
 Set the core port to 1000, and the abort port to 1001.
 Click on the 'On' Checkbox and make sure the box is checked.
VXI-11 on the SR1 should now be enabled.
Define the VXI-11 interface on your remote PC.
Moving to the remote PC, we will now define the device in the NI MAX program:
 Start NI MAX
 In the tree view on the left side of the panel, click on the arrow next to 'My
System' to expand the entry.
 Right click on 'Devices and Interfaces' and select 'Create New...'
 In the pop up window, click on 'VISA TCP/IP Interface'
 Click 'Next'
 On the next screen, click on the 'Manual Entry of LAN Instrument' radio button
 Click 'Next'
 On the next screen, click on the 'Manually specify address information of LAN
instrument' radio button
 Click 'Next'

 On the next screen, enter the IP address
 For LAN Device Name, type 'inst0'
 Click 'Validate' to verify the connection to your SR1 instrument
 Click 'Next'
 Enter an alias name if you wish
 Click 'Finish'
Your SR1 instrument should show up in the tree view under Network Devices and
should now work over VXI-11.
Testing your VXI-11 connection:
 Right-click on the SR1 item and selecting 'Open VISA Test Panel'
 Once there, click on the 'Input/Output' button on top.
 Then press the 'Query' button to send and receive the response to a *idn?
command.
