Serial Interface RS422
optoNCDT 1700
Name: SET_AVX
Description: Sets the averaging number N for the moving and recursive averages to N=2^X.
Value range for X : 0...15 (0x00...0x0F). This command is not available for the median. If attempted, the sen-
sor issues the message „Command failed“.

(N) N = averaging number
This results in the following values for the averaging number N:
N 1 2 4 8 16 32 64 128 256 512 1024 2048 4096 8192 16384 32768

Overview: Command Averaging number N
recursive average moving average Median
SET_AV 0...3 1, 4, 32, 128 1, 4, 32, 128 3, 5, 7, 9
SET_AVX 1 ... 32767 1 ... 128 Command failed
Example:
Average 8 X = log

(8) = 3
Average 512 X = log

(512) = 9
IMPORTANT!
SET_AVX is not avai-
lable for the median!
The maximum value for
N for the moving aver-
age is 128.
Note: The “avg“ LED
goes off after SET_AVX.
Advice: If the existing
averaging number
is higher than that
permitted for the new
averaging type, the
averaging number will
be set to the upper limit
for the new average
type.
