Note that the Load Monitor must reside on the same network as the Supervisor. That is, it
cannot be separated by a hub.
3.3 Network Terminations & Bus Wire Type
In order to minimize data reflections, the network domain must be properly terminated at
extreme ends. Terminating a network is accomplished by placing a resistor (chosen to match
the characteristic impedance of the cable) across the twisted pair.
Crest Audio recommends using Belden 8442 unshielded twisted pair cable with 110
Ω
ter-
minating resistors. Other cable may be used; however, the maximum transmission distance
may decrease due to increased distributed capacitance of the cable. Use of other cable may
also require different terminating resistors. Mixing different cable types on the same net-
work or the use of star topologies within the same network must be avoided due to the
impedance mismatch between cables. All cables must have a characteristic impedance of
100
Ω
at 100kHz.
All bus connections are opto-isolated, thus eliminating any ground loops and to minimize
RF interference.
