The RTG system requires the use of a configuration file, named RTG Configuration Support.ini, which is located on Windows systems at: <Public Documents>\National Instruments\RTG.

The RTG installer includes an example of this file located in the same folder, named RTG Configuration Support-Template.ini. You can use this file to start creating your own custom configuration. A customization will be preserved when upgrading because the RTG installer does not overwrite this file, however it will overwrite the template. When the RTG is run, the software creates an INI file based on the existing template if it cannot find this file.

Use the INI file in the following scenarios:

  • You need a static configuration for the RTG.
  • You need to set up a complex configuration RTG, thus eliminating the need for a lengthy option string.
  • You want to switch between multiple configurations. In this case you would maintain an INI file for each configuration.
  • You want to set up a secure encrypted remote connection.

Within the file, users can specify and set parameters similar to that of the Option String. Note that the only properties that cannot be overwritten are in the Setting section where both the ServerIP and ServerPort keys are specified for remote functionality.

Table 34. Setting Section Keys
Key Value Default Value Required?
ServerIP Server default IP address. localhost Required
ServerPort Server default Ethernet port static IP address. 50052 Required
SSLPrivateKeyPath The path of the private key for encrypted remote API communication. "" Not required
CertificatePath The path of a Signed Certificate on the system containing the server for encrypted remote API communication. "" Not required

The format for setting these parameters is as follows: 

[Section 1] 
Key_1A = Value_1A 
Key_1B = Value_1B 

[Section 2] 
Key_2A = Value_2B 
Key_2B = Value_2B

The following is an example of a basic INI file setup for configuring the RTG: 

[Setting] 
ServerIP = 12.34.56.78 
ServerPort = 50052
CertificatePath: "C:\Users\LabVIEW\Server.crt"
SSLPrivateKeyPath: "C:\Users\LabVIEW\Server.key" 

[DriverSetup]  
personality = pulse aware 
CertificatePath: "C:\Users\LabVIEW\Client.crt"   

[5841_1]  
pxi_trigger_output = PXI_Trig7  
pxi_trigger_input = none  

[6594_0] 
bitfile_path = <LabVIEW>\examples\RTG\Coprocessor\Passthrough\NI 6594\CLIP 8 SPC (-00)\FPGA Bitfiles\rtg-passthrough-template-ni6594-00.lvbitx 
min_latency = 2.72E-6 
timeout = 10

Refer to RTG Configuration Sections and Keys for information about updating the INI file for different system configurations.
