Dawson driver board

Hi can anyone help me with the dip switch codes for a dawson driver board.
Code: Select all
For a working example, see Figure 1.
Multiply your frequency by 10.
Multiply the result by 2.
Write down the result vertically on a piece of paper.
Referring to Table 1, write down the corresponding binary code next to each digit of the result.
Write numbers 01 to 16 down the page.
Write each digit of each binary code down next to one of the numbers 01 to 16 in sequence.
Place the exciter in front of you with the dip switches to the left.
Referring to Table 2, switch all of the dip switches to off and then proceed to switch on all dip switches corresponding to numbers 01 to 16 where you have written a 1 next to them.
As a check, use Table 2 to add up all the frequency values you have switched on and multiply them by 2. This result should equal your frequency.
