Figure 42: Connecting the LDALI-ME20X: (a) 2-wire MS/TP, (b) 3-wire MS/TP.
Important: When using 2-wire MS/TP, earth ground must be connected to both terminal 24 and 25
(see Figure 42a). Never connect terminal 26 to earth ground!
4.9.2 LDALI-3E10X and LDALI-3101-U
Any CEA-709 FT-10 network segment connected to the L-DALI needs to be terminated
according to the rules found in the specification of the transceiver (see Section 9.1).
Important: When using shielded network cables, only one side of the cable should be connected to
earth ground. Thus, the shield must be connected to earth ground either at the L-DALI
terminals or somewhere else in the network.
