1797-RPA 1797-RPA ControlNet Ex
Modular Repeater
Adapter Represents one ControlNet Ex
node and must be connected
to a coax trunk cable by

1797-TPx
1797-RPFM 1797-RPFM ControlNet Ex Fiber
Repeater Module,
Medium Distance Allows connection of a
maximum of two devices per
1797-RPA and is powered
directly by 1797-RPA
1797-ACNR15/B 1797-ACNR15/B Redundant Media
ControlNet Ex
Adapter
Represents one ControlNet Ex
node and must be connected
to a coax trunk cable by

1797-TPx -each one with two
redundant output channels
that are connected to different
ControlNet Ex networks (coax
cables and 1797-TPx)
CNet Ex Tap Trm 1797-TCAP ControlNet Ex Tap
(Dummy) Terminator Represents one ControlNet Ex
node and is a simple capacitor
(56 pF) 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
) with
coax connector that must be
on each end of the ControlNet
Ex coax trunk for termination
Coax Trunk Cable 1786-RG6 Quad-Shield, RG-6

 Coax Trunk
Cable
Maximum (functional) length
between 2 1797-TPx is 1000 m
(3280 ft) - each 1797-TPx
reduces the (functional) coax
cable length by 16.3 m (53.4 ft)
None None Standard Coax Trunk
Cable BNC Couplers Different standard cable
couplers, such as 90
o , 180 o .
