weighted decimal

0, output signal is present. Hence value of 0 indicates that all
outputs are outputting the source signal. If there was no output
from outputs 2 and 3, the response would be:
6 (1*0 + 2*1 + 4*1 + 8*0 + ... = 6)

Boolean
Provides status on each output (lowest numbered output to
highest). 0 = signal at output, 1 = no signal at output. Same
result as PACKed? (see prior command), but information on

were not outputting the source signal, the response would be:
0,0,1,0,1,0,0,0,0,0,0,0
