①
Electrical isolation
②
Technology and backplane bus interface
③
Input filter for supply voltage
④
Supply voltage via infeed element
⑤
Duplicate wiring to the ground connection of the central power supply of the system
⑥
Shield connection at the front connector
⑦
Equipotential bonding
⑧
LEDs per channel
⑨
Twisted-pair cables
