Sync +/Sync 3/4 Synchronizaton
1
Symmetrical synchron output (Master) or synchron input (Slave)
Tx +/Tx - 1/2 Serial output RS422 Terminate with 120 Ohm receive-site
Rx +/Rx - 12/11 Serial input RS422 Internally terminated with 120 Ohm
1) Input is used for triggering in trigger mode, see Chap. 6.14.
2) The use of a 10 nF capacitance at the entrance for interference suppression is recommended.
The LEDs on the
sensor, see Fig. 20,
have different indicator
functions depending
on whether the sensor
is in measurement
mode or setup mode.
IMPORTANT!
Disconnect or connect
the D-sub connection
between RS422 and
USB converter when
the sensor is discon-
nected from power
supply only.
