Please see the attached extract from the operating manual.

Instead of using P701 = P703 = 17, we will be using the BICO method (These will already be changed because of the earlier mentioned mods), so P701 = P703 = 99. What this means is that the status of the Digital inputs (i.e. r722.0 and r722.2 can be used as many times as we like)

Now we need to activate some other signals, but as I don't know which bits have been used for the fixed frequencies, I WILL ASSUME that the two lowest order bits have used for the frequency selection. You will either need to check your existing parameters, or upload an archive of your Starter/Scout project and I can tell you exactly which parameters need altering.

P1020 = r722.0

P1021 = r722.2

P1016 = 3

P1017 = 3

With this in mind, P1001 to P1004 will contain the fixed frequencies that you will be using.

Note, the modifications mentioned before will still function as you wanted.

Best regards,

Graeme
