System requirements
The receivers that are connected (e.g. UFS 821, UFS 712 etc.) must control the single-cable mode (SDU and/or MDU) to
EN 50494. Receivers without single-cable mode to EN 50494 cannot operate in conjunction with the EXU 908; they interfere
with the operation of the system.
The cabling must use splitters (e.g. EBC 10/13/14) and sockets (e.g. ESU 33/34) that are suitable for single-cable operation.
If a receiver that is connected has no polarity reversal protection, the sockets or splitters that are used must incorporate
this feature (diode decoupling). The end of the loop-through input must be terminated with a suitable DC-decoupled 75 Ω
resistor (e.g. ERA 14).
