The signals Sync-in/out or /Sync-in/ of same polarity are con-
nected in parallel with each other. A sensor is to program as a
synchronous master, which supplies the subsequent slave sen-
sors with symmetric synchronous pulses, RS422-level. Only in the
last slave sensor in the chain the terminating resistor is activated
of 120 Ohm, see Chap. 7.6.3. The system grounds (pin 2) of the
sensors are to connect to each other.

If you synchronize the sensor with an external signal source, the levels of the signal source have to comply with the EIA-422-spezifi-
cations. The difference between both input signals Sync+ (pin 5) and Sync- (pin 6) must be according to amount greater than 400
mV. Synchronization source may be, for example, a level converter, which converts TTL/HTL signals into RS422 level. Micro-Epsilon
recommends the level converter SU4-1 from LEG Industrie-Elektronik. The synchronization rate is to take from the table, see Fig. 42.
Pulse duration and non-pulse period have a ratio of 1:1.
Input or output is to select according to the type of synchronization.
