Crestron CNXRMCS Current Sensor for Room Solution Boxes
Current Sensor for Room
Solution Boxes: CNXRMCS
Introduction
The Current Sensor for Room Solution Boxes, CNXRMCS, senses the
current from a television (9” color or larger) or other high current
electronic devices. Since most infrared (IR) remotes send the same IR
signal to turn a device ON or OFF (no discrete on and off power
commands), the CNXRMCS lets the control system know whether a
device is ON or OFF by indicating a high (ON, which indicates high
current draw) or low (OFF, which indicates low or no current draw)
digital signal to a Room Solution Box, such as the CNXRMC,
CNXRMCLV, or to an I/O port on any control processor.
NOTE: The CNXRMCS is not designed for use with low power devices
such as a VCR, DVD, DSS, etc.
Functional Summary
• Senses current draw from 9 inch or larger televisions
• 2-pin connector interface to Room Solution Boxes
• 6-foot cord included

Physical Description
Refer to the physical views in the following illustration. The CNXRMCS
contains an AC plug on one side and an AC outlet on the other. The cord
to the 2-pin connector is approximately six feet long and is polarized with
the solid black wire for ground and the striped wire as the signal wire.
The connector attaches to the SENS port of a Room Solution Box.

Setup
Connector Wiring
Insert the 2-pin connector in the current sensor connection (labeled
“SENS”) on a Room Solution Box. The solid black wire of the digital
connector cord must be attached to pin 2 (G or ground pin) of the
connector and the striped wire must be attached to pin 1 (signal).
Plug the CNXRMCS in an AC outlet and the high current device in the
CNXRMCS. Refer to the following illustrations.

Programming
For a control system to recognize the ON/OFF state of a high current
device from the CNXRMCS, a program must be created in SIMPL
Windows. The <Current Sense> output goes high when the monitor (i.e.,
television) in the room is on, and low when the monitor is off. The
CNXRMCS provides a contact closure and is attached to the two-pin port
(labeled SENS) on the CNXRMC or CNXRMCLV. Refer to the latest
version of the CNXRMCLV (Doc. 8161) Operations Guide in the
Downloads | Product Manuals section of the Creston website
(www.crestron.com) for more information.

Problem Solving
Troubleshooting
The table below provides corrective action for possible problems with the
CNXRMCS. If further assistance is required, please contact a Crestron
customer service representative.
CNXRMCS Troubleshooting
TROUBLE POSSIBLE
CAUSES
CORRECTIVE ACTION
Television or other
high current device not
drawing enough
current to trigger
CNXRMCS.
If the device does not draw
enough current, Crestron
recommends that you use the
ST-CS or CNCS Current
Sensors. Refer to the latest
revisions of the ST-CS (DOC.
5677) or CNCS (DOC. 8079)
Operation Guides, in the
Downloads | Product
Manuals section of the
Crestron website
(www.crestron.com)
for more information.
Television not
operating properly.
Verify that the television turns
OFF/ON manually.
Room Solution
Box not sensing

OFF/ON status.
CNXRMCS digital
output wires or
connector not firmly
connected.
Verify that each digital output
wire and the 2-pin connector
are firmly connected.
CNXRMCS is not
receiving power.
Confirm that the power outlet
has AC voltage and that the
CNXRMCS is firmly plugged
in the outlet.
No power to
television or
other high
current device.
CNXRMCS is not
transferring power to
its outlet.
Confirm that the CNXRMCS
outlet has AC when plugged
in the power outlet and the
high current device plug is
firmly plugged in the
CNXRMCS outlet.
