Cabling
General Usage
Trunk /Drop Connection
– Remote I/O devices should only be
connected to the DROP connector of the Master or Slave units. Never
connect RIO devices directly to the TRUNK connector. The TRUNK
signals contain high-frequency signals that may damage the Remote I/O
device.
Trunk/ Drop Termination
– Each trunk segment, as well as each Drop
Line of Blue Hose cabling should be terminated with (2) 150 Ohm
Resistors (one on each end of the physical cable). Always remove any
existing 82 Ohm resistors.
