Badger Meter K-Factor Scaler - Manual (Page 9)

To determine the maximum current available using a specific pullup resistor use the following equation
Current Draw =
0.25 Watts
External Pullup Resistor
STARTUP
Using Optional Programming Software Kit B220-900
(Software sold separately)
The programmable K Factor Scaler can be factory or user configured through a serial port of a PC by a Windows compatible
software utility A programming adapter is required that interfaces the serial port from the PC to the programming port on
the board
To program the K Factor Scaler:
1 Begin with the power turned off and connect the adapter cable to the K Factor Scaler board using the programming
port (see Figure 2)
2 Connect the serial-to-TTL converter to the adapter cable See Figure 5
3 Attach the serial extension cable to the serial-to-TTL converter and connect the opposite end to an available nine-pin
serial port of a PC
NOTE: N For computers without a 9-pin serial connection a serial to USB converter may be required
4 Turn on the power to the K Factor Scaler
NOTE: N Power to the K Factor Scaler is required in order to perform any programming

Figure 5: Interface connection
The programming interface uses two functional divisions as shown in Figure 8 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
Selection of the proper computer serial port within the Blancett K Factor programming software is required for it to
communicate with the board From 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
