Profile Selection via digital inputs
For instruments with the profiler option, the multi-digital input option can be used to select the
profile to run using either a standard binary bit pattern, or binary coded decimal from BCD
switches. Profile selection inputs are all level sensitive ( █ ), with a high/open signal equating
to a binary 1 (assuming non-inverted), and a low/closed signal equating to a binary 0
(assuming non-inverted).
Profiles are numbered 0 to 63. Select inputs C1 to Cn for the required number of profiles,
from the table:
C1 C1 to C2 C1 to C3 C1 to C4 C1 to C5 C1 to C6 C1 to C7
Binary 0 to 1 0 to 3 0 to 7 0 to 15 0 to 31 0 to 63
BCD 0 to 1 0 to 3 0 to 7 0 to 9 0 to 19 0 to 39 0 to 63
Using Binary To Select Profile Numbers
Selection of profiles is via a simple binary bit pattern. C1 is the least significant bit (LSB).
C6 to C1 C5 to C1 C4 to C1 C3 to C1 C2 to C1 C1
000000 to 111111 00000 to 11111 0000 to 1111 000 to 111 00 to 11 0 to 1
(0 to 63) (0 to 31) (0 to 15) (0 to 7) (0 to 3) (0 to 1)
Using BCD To Select Profile Numbers
A single BCD switch can be used to select profiles 0 to 9 using C1 to C4, with a bit pattern identical to
standard binary. For larger numbers, a double BCD switch arrangement is needed. A separate binary
pattern is applied to C5 to C7 for the “tens” digit (10 = 001, 20 = 010, 30 = 011 etc).
Any number combination higher than 63 is invalid.
Multiples of ten (0x to 6x) Multiples of one (x0 to x9)
