Terminal significance
UB
GND
T,R IN
T,R OUT
Encoder voltage supply.
Encoder ground connection relating to UB.
Serial data lines.
To avoid stub lines the data lines are
guided outside on a pair of 2 wires. The
arriving bus is on T,R+ IN and T,R- IN, the
departing bus on T,R+ OUT und T,R-. If the
encoder serves as bus termination or is
the only user, only the pair of wires T,R+ IN
and T,R- IN is utilized. Note: External
connection of terminating resistor 150
Ω
to
final
user.
Ident 0...2 are utilized for setting the
encoder addresses
(identifiers).
Less
potential the inputs are internally against
UB
(=“1“)
by
pull-up
resistors what
equals
address 1.
