Cascading output OutCas
In order to operate several light section sensors cascaded this output must be connected
directly to the trigger input of the following sensor. Detailed information on this topic can
be found in chapter 4.2.4. The internal equivalent circuit is shown in figure 6.6.
Output "ready" OutReady
This output indicates operational readiness of the sensor. The state of the output corre-
sponds to the state of the green LED (see "LED status displays" on page 53).

Connection X2 - Ethernet
Attention!
All cables must be shielded!
The LES makes either the Ethernet interface available as host interface.
Preferably, please use the ready-made cables "KB ET-…-SA…", see chapter 15.2.3.

HOST / BUS IN cable assignments on RJ-45
Notice for connecting the Ethernet interface!
Ensure adequate shielding. The entire connection cable must be shielded and earthed. The
Rx+/Rx- and Tx+/Tx- wires must be stranded in pairs.
Use CAT 5 cables for the connection.
