2.5.5. 2.5.5.
The DS-4TXB module provides 4 100M fast Ethernet electrical interfaces. The physical interface is an
RJ-45 connector and the C5 twisted pair cable is used whose transmission distance is 100 m. The
MDI/MDIX self calibration function is supported. The cable length and peer interface type depend on
the real situation.
