GXM7W.010A002 Datasheet, PDF (3/4 Pages) Baumer IVO GmbH & Co. KG – Absolute encoders - bus interfaces

Absolute encoders - bus interfaces
Shaft with clamping or synchro flange
Multiturn encoder 13 bit ST / 12 bit MT, RS485-SLIN
GXM7W - SLIN
Terminal significance
UB
Encoder voltage supply.
GND
Encoder ground connection relating to UB.
T,R IN
T,R OUT
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
Address no.
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.
