OTE: 

N

The programming software is sold separately 

The programming interface uses two functional divisions as shown in 

Figure 6

  The 

Program Values column contains the user-selected information for downloading 

into the K-factor scaler  The Board Values column shows the information that the 

K-factor scaler currently contains and is not alterable by the user  The Board Values 

column will only display the contents of the board after performing a Program, 

Read or Verify function

Programs the K-factor, Pulse Width and Pulse Output to the 

K-factor board  

Read

Reads the current information from the K-factor board and displays it 

under the 

Board Values

 column of the PC software 

Verify

Compares the 

Board Values

 to the 

Program Values

 and displays an 

error if the two do not match 

Selecting the Com Port

Select the proper Com port within the programming software so the software 

can communicate with the board  To select the Com port, in the menu bar select 

Tools and then Com Port  Select the Com port (1…16) that the serial programming 

cable is connected to on the computer
