Description
Enable 5 V
on output
channel
(A, B, N, MF)
Enables 5V power supply on V
CC
.
TTL Threshold
Voltage
channel
(A, B, N, MF)
Adjusts the threshold for the detection of
logical „0“ and logi-
cal
“1“ (only when TTL mode is active).
Enable 1k
Pullup
on external
voltage
channel
(A, B, N)
Enables the 1 k
Ω pullup resistor on external voltage V
CC
.
Enable 1k
pulldown
channel
(A, B, N)
Enables the 1 k
Ω pulldown resistor.
Enable 1k
Pullup
on internal
5 V
channel
(A, B, N)
Enables the 1 k
Ω pullup resistor on internal 5 V.
Enable 120R
differential
termination
A / B / N
Enables the 120
Ω termination resistor between the positive
and negative signal.
Can also be used as pulldown resistor together with 1 k
Ω
pulldown for TTL mode.
Enable analog filter
on TTL input
A / B / N / MF Enables the 180 kHz RC low-pass filter.
(only when TTL mode is active).
1=TTLMode
0=DiffMode
A / B / N
Switch between differential and single-ended signal.
Invert
Polarity
A / B / N / MF Inverts signal polarity.
Enable debounce
filter
A / B / N / MF Enables one of the debounce filters, see chapter 7.6.2.
Enable
270R
Pullup
to internal
5 V
MF
Enables the 250
Ω pullup resistor to internal 5 V.
Important note
The figures of the channel wiring only show the physical layout of a channel and what is
technically possible. Depending on the rotary encoder type, fixed values are assigned to
the switch settings.
7.4.4
Theory
This chapter describes the internal calculation methods and the corresponding parame-
ters.
The following table gives an overview of the possible settings and the range of functions.
Individual items are described in the following chapters.
