Display Elements - Hirschmann RS20 User Manual

Power supply and data cables should not run parallel over longer
distances, and ideally they should be installed in separate cable
channels. If the inductive coupling has to be reduced, the power
supply and data cables should cross at a 90° angle.
You may also choose to use shielded cables. Ground the cable
shielding at one point in order to avoid causing a ground loop.
100 Mbit/s fiber optic connection
100 MBit/s fiber optic ports (SC, SFP slot) enable the connection of termi-
nal devices or independent network segments in compliance with the
IEEE 802.3 100BASE-FX standard. These ports support:
Full or half duplex mode
Default settings: full duplex
Note: Make sure that the LH ports are only connected with LH ports, SM
ports are only connected with SM ports, and MM ports only with MM ports.
1 Gbit/s fiber optic connection
1 GBit/s fiber optic ports (SFP slot) enable the connection of terminal de-
vices or independent network segments in compliance with the IEEE
802.3-2000 (ISO/IEC 8802-3:2000) 1000BASE-SX or 1000BASE-LX
standards. These ports support:
Autonegotiation
Full duplex mode
Default settings: autonegotiation
Note: Make sure that the LH ports are only connected with LH ports, SX
ports are only connected with SX ports, and LX ports only with LX ports.

Display elements

After the operating voltage is set up, the software starts and initializes itself.
Afterwards, the device performs a self-test. During this process, various
LEDs light up. The process takes around 70 seconds.
