NOTE:The line should be terminated at both ends with its characteristic impedance (RT = ZO). Stub lengths off the main line
should be kept as short as possible.

Figure 22. HVD12 Input and Output Through 2000 Feet of Cable
An example application for the HVD12 is illustrated in
Figure 21. Two HVD12 transceivers are used to
communicate data through a 2000 foot (600 m) length of
Commscope 5524 category 5e+ twisted pair cable. The
bus is terminated at each end by a 100-
resistor,
matching the cable characteristic impedance. Figure 22
illustrates operation at a signaling rate of 250 kbps.
