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

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.

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.

operating properly.

Verify that the television turns

OFF/ON manually.

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.
