Redundant Media
Adapter Allows connection between a
ControlNet system and a
ControlNet Ex system
CNet Ex Tap Trm 1797-TCAP ControlNet Ex Tap
(Dummy) Terminator Represents one ControlNet Ex
node and is a simple capacitor
(56pF) with a coax connector
ControlNet Ex
Tap 1797-TPx ControlNet Ex Coax
Tap Four types of connections
available: S (straight t-tap), R
(right angle t-tap), YS (straight
y-tap), and YR (right angle
y-tap) - a maximum of 48 taps
can be connected together by
coax trunk cable
CNet Ex Trk Trm 1797-XT ControlNet Ex Trunk
Terminator Simple resistor (75
Ω) with
coax connector that must be
on each end of the ControlNet
Ex coax trunk for termination

Maximum (functional) length
between 2 1797-TPx is 3280ft
(1000m) - each 1797-TPx
reduces the (functional) coax
cable length by 53.4ft (16.3m)
None None Standard Coax Trunk
