This  document  and  the  information  contained  is  property  of  RTX  A/S,  Denmark,  and  should  be  regarded  as  confidential.

  

Unauthorized copying is not allowed. The information in this document is believed to be correct at the time of writing. RTX A/S 
reserves the right at any time to change said content, circuitry and specifications. 

The license file will be copied to the RTX2018 program folder. For DLL operation, it is necessary 
that a valid license file is present in the same folder as the DLL.  
 
The license file should look something like this: 
 

"SerialNumber": 

"1201.0002k03/106863", 

"LicenseCode": 

"0563467856cd1b4306ffa5ad8ee2b938", "ExpireDate": "31-03-2019" 
}c 
 
This license file allows the DLL to operate with the  specific CMW100 HW and related serial 
number(s) as shown in the license file.  
 
In case of multiple RTX 2018, the user can have up to 10 to serial numbers in a single license 
file to enhance the flexibility for the user: 
 

"SerialNumber": 

"1201.0002k03/107463", 

"LicenseCode": 

"0563467856cd1b4306ffa5ad8ee2b938", "ExpireDate": "31-03-2019" 
"SerialNumber": 

"1201.0002k03/106573", 

"LicenseCode": 

"1b4306ffa5ad8ee2b9380563467856cd", "ExpireDate": "31-06-2019" 

 
The third dialog box (see Figure 3 below) describes how to install the waveform files.
