total from the subtraction and subtract the next largest number possible and so on until
the result is zero. Each value that was used in the subtraction indicates that the
Transmitter is online.

For example: The On/Offline Status holding register contains the value 15. In this case
the largest value we can subtract is 8, which leaves a result of 7. Now we can subtract 4
from 7 and get 3. Now subtract 2 from 3 and we get 1. Finally we subtract 1 from 1 and
get 0, so we are done. Which Transmitters are online? We subtracted 8,4,2 and 1, and
these numbers correspond to Transmitters’ with RF IDs 1,2,3 and 4.

Note An alternate method to determining which Transmitter(s) are online is to look at the
Base Radio Holding Register as a binary number with the rightmost bit representing
Transmitter 1 and the leftmost bit representing Transmitter 16. For example, the binary
representation for Transmitters 1-4 online is as follows:

0000000000001111

In another example, say the On/Offline Status holding register contains the value 6. We
can subtract 4 to get 2. Then we can subtract 2 to get 0. Thus Transmitter 2 and 3 are
online, but Transmitters 1 and 4 are offline.
