Input and Output Ports
Connections to the CNXRMCLV are made through the ports on the front and rear
panels. Refer to the illustrations and descriptions, which follow.
AUDIO
The RJ-45 AUDIO port is used to transmit and receive analog stereo audio from the
head end. Refer to the diagrams on page 7 for pin configurations.
VIDEO OUT
The RJ-45 VIDEO OUT port can be used to send up to four baseband video signals
out of the unit and back to the head end. A Crestron (CNX-PBVR4) or third-party
video receiver must be used to convert to single-ended RCA for input to the
CNX-PVID. Refer to the diagrams on page 7 for pin configurations.
VIDEO IN 1-2-3-4
The RJ-45 VIDEO INport connects toavideo distributionbox suchas the
CNX-PVID8 and accepts four baseband/balancedvideo signals corresponding to
each of the fourlevels provided by the CNX-PVID8. This connection can distribute
high definitioncomponent video and multi-channel digital audio, or combinations
of S-video and/or compositevideo. Three of the videosignals have cable length
compensation. The fourth video signal has fixed compensation and can be used for
composite video or digital audio distribution. Refer to the diagrams on page 7 for pin
configurations.
Each local video source input has a built-in video sensor.
RS-232
The CNXRMCLV provides one RJ-11 connector for RS-232 communication with
serial devices. This port supports baud rates of up to 115K and RTS/CTS hardware
handshaking. The pins are configured as shown in the following table:
Pin Function
1 CTS (Clear to Send)
2 GND
3 RXD (Receive)
4 TXD (Transmit)
5 RTS (Request to Send)
6 Not connected
VIDEO IN (5 - 8)
These four RCA connectors provide for video input (any combination of composite,
S, or component, including HDTV), with built-in 75-Ohm termination.
VIDEO OUT (A – H)
These eight RCA connectors provide local (analog) video outputs.
Local audio can be routed to the head end, from where it can be distributed to a room
via speaker level from the CNX-BIPAD8/CNAMPX-16x60 combination. Local
audio sources can also be routed to the record-out outputs. The unit’s primary audio

Room Solution Box with Local Video Crestron CNXRMCLV
6 •Room Solution Box with Local Video: CNXRMCLV Operations Guide - DOC. 8161A
output provides volume and tone adjustments, whereas the record output does not.
Refer to the following block diagrams for further details of the routing capabilities.
AUDIO IN (A – C)
These six RCA connectors provide for three local stereo input sources.
AUDIO OUT
The two RCA connectors labeled OUT provide stereo output of the unit’s analog
crosspoint, but with volume/tone control.
The two RCA connectors labeled REC OUT provide stereo output of analog
crosspoint, without any processing.
IR IN / IR OUT
The CNXRMCLV provides one infrared (IR) input, which is a mini phone jack that
can connect to a Crestron IR detector (CNXRMIRD) to detect fixed low frequency
(38 KHz) IR formats generated by most universal remote control transmitters. This
port supports RC5 IR control and some IR control codes from Sharp Electronics
Corporation.
The four IR outputs (A – D) are used to control either IR or one-way serial devices,
not both. These outputs can also be connected to optional Crestron equipment such
as the STIRP, ST-MB, ST-SPL, SP-RY, and SP-SC.
SENS
As described previously, the CNXRMCLV contains a contact closure type input
accessed via this two-pin connector. The port can be connected to a Crestron current
sensor (CNXRMCS) or any other device that provides contact closure to detect the
power status of a high-power device such as a television.
NET
This four-pin connector is used to connect to other four-wire devices in the Cresnet
system. This connector must be attached to power the unit and communicate with the
control system.
LED Indicators
The CNXRMCLV provides three LED indicators. The PWR (Power) indicator goes
on when the unit is supplied with 24 volts DC from the network. The NET indicator
is typically on when the unit is polled on the network (some flashing may occur).
The NET LED indicates that the current program has a network device defined at the
same Net ID as the CNXRMCLV. (The SETUP indicator and button are reserved
for a function that is to be available in the near future.)
VIDEO INPUT COMP 1, 2, 3
The CNXRMCLV provides three potentiometers (pots) that can be adjusted to
compensate for CAT5 cable run lengths. Refer to “Video Input Compensation” on
page 10 for the adjustment procedure.
Audio/Video Signal Routing
Refer to the block diagrams on the next page for additional details of the
CNXRMCLV signal routing capabilities.

Setup
Network Wiring
NOTE: When installing network wiring, refer to the latest revision of the wiring
diagram(s) appropriate for your specific system configuration, available from the
Downloads | Product Manuals | Wiring Diagrams section of the Crestron website
(www.crestron.com).
When calculating the wire gauge for a particular network run, the length of the run
and the power factor of each network unit to be connected must be taken into
consideration. If network units are to be daisy-chained on the run, the power factor
of each network unit to be daisy-chained must be added together to determine the
power factor of the entire chain. The length of the run in feet and the power factor of
the run should be used in the following resistance equation to calculate the value on
the right side of the equation.
Resistance Equation
R = Resistance (refer to table below).
L = Length of run (or chain) in feet.
PF = Power factor of entire run (or chain).
R < L x PF
40,000 Where:
The required wire gauge should be chosen such that the resistance value is less than
the value calculated in the resistance equation. Refer to the table after this paragraph.
Wire Gauge Values
RESISTANCE (R) WIRE GAUGE
416
618
10 20
15 22
13 Doubled CAT5
8.7 Tripled CAT5
NOTE: All network wiring must consist of two twisted-pairs. One twisted pair is
the +24V conductor and the GND conductor and the other twisted pair is the Y
conductor and the Z conductor.
NOTE: When daisy chaining network units, always twist the ends of the incoming
wire and outgoing wire that share a pin on the network connector. After twisting the
ends, tin the twisted connection with solder. Apply solder only to the ends of the
twisted wires. Avoid tinning too far up or the tinned end becomes brittle and breaks.
After tinning the twisted ends, insert the tinned connection into the network
connector and tighten the retaining screw. Repeat the procedure for the other three
network conductors.
Identity Code
Every equipment and user interface within the network requires a unique identity
code (Net ID). These codes are two-digit hexadecimal numbers from 03 to FE. The
Net ID of each unit must match an ID code specified in the SIMPL Windows

Crestron CNXRMCLV Room Solution Box with Local Video
Operations Guide – DOC. 8161A Room Solution Box with Local Video: CNXRMCLV •9
program. Refer to “Setting the Net ID in Device Settings” on page 19 for details of
the SIMPL Windows procedure.
Refer to the note on page 26 for a
definition of Viewport.
The Net ID of the CNXRMCLV has been factory set to 42. The Net IDs of multiple
CNXRMCLVs in the same system must be unique. Net IDs are changed from a
personal computer (PC) via the Crestron Viewport.
NOTE: For detailed information on establishing communication between the PC and
control system, refer to “Communication Settings” on page 26. If communication
cannot be established, refer to the “Troubleshooting Communications” section in the
respective Operations Guide for the control system.
Complete the following steps to change the Net ID
1. Ensure that the device requiring a Net ID change is the only unit
connected to the control system.
2. Open the Crestron Viewport.
3. From the Viewport menu, select Functions | Set Network ID. The
software checks the baud rate and then opens the "Set Network ID"
window.
4. In the "Set Network ID" window, select the device requiring a Net ID
change from the Current Network Devices text window.
5. Select the new Net ID for the device from the Choose the new network
ID for the selected device (Hex): text box.
6. Click Set ID to initiate the change. This will display the "ID command
has been sent" window.
7. In the "Command Complete" window, click OK.
8. In the Current Network Devices text window, verify the new Net ID
code.
9. In the "Set Network ID" window, click Close.
NOTE: The new Net ID code may also be verified by selecting Diagnostic | Report
Network Devices in the Viewport (alternately, select F4).
10. Repeat this procedure for each additional network device requiring a
Net ID change.
Mounting
Two screw holes in each bottom flange accept #6 screws (not supplied). The
CNXRMCLV can be mounted in any orientation. Mounting hole spacing dimensions
are illustrated in “Physical Description” which begins on page 3.
Hardware Hookup
The CNXRMCLV is capable of tremendous flexibility in audio and video signal
distribution. Refer to “Audio/Video Distribution” on page 10 for detailed
information. Other than making the power connection (NET) last, complete the
connections in any order.
NOTE: Refer to "Network Wiring" on page 8 when making connections to the port
labeled NET.

Video Input Compensation
After the system is connected, it may be necessary to adjust the video input
compensation pots on the CNXRMCLV to achieve the best picture on the monitor.
This requires a narrow slotted screwdriver and an audio/video calibration DVD (or
laser disc). Crestron recommends one of the following:
• Avia Guide to Home Theater, from Ovation Software
(www.ovationsw.com)
• Video Essentials, from DVD International (www.videoessentials.com).
To adjust the video input compensation:
1. Place the calibration disk in the system's DVD player.
2. Search the DVD for the chapter that displays the multi-burst pattern, as
shown in the following illustration.
3. While the pattern is being displayed on the monitor, use the
screwdriver to adjust the VIDEO INPUT COMP 1 compensation pot
until the line intensity on the monitor appears uniform. Note the
numeric value.
4. Adjust the other two compensation pots (VIDEO INPUT COMP 2
&3) to the same value as the VIDEO INPUT COMP 1 compensation
pot.
NOTE: For S-video and component video sources, be sure to adjust the pot for
luminance compensation first (VIDEO INPUT COMP 1). The pots for
chrominance compensation should be adjusted last.
Audio/Video Distribution
As previously stated, the CNXRMCLV receives video and digital audio from the
Crestron CNX-PVID, as well as analog audio from the CNX-BIPAD8, all via CAT5
cabling. In addition, it receives video, digital audio and analog audio from local
sources via standard RCA connections. The unit’s built-in audio/video matrix
switcher distributes these inputs to local outputs.
The following paragraphs describe several signal distribution arrangements that are
typical for the CNXRMCLV.
NOTE: For additional information on video connections over CAT5, refer to the
latest version of the Crestron CAT5 Wiring Reference Guide (Doc. 6137) which is
available from the Downloads | Product Manuals section of the Crestron website
(www.crestron.com).

Distribution of Analog Audio to/from the Head End
Analog audio from source devices is distributed by the CNX-BIPAD8 (BIPAD8) or
CNX-PAD8 (PAD8), then passed through a Crestron amplifier (CNAMPX), and
delivered as speaker level audio to the local set of speakers. Analog audio can be
directed from the CNXRMCLV back to the BIPAD8 directly, via CAT5, for further
distribution.

Universal Remotes
Any universal remote transmitting RC5 code (and some Sharp codes) can
communicate with the CNXRMCLV and allow the user to select and activate any
function in the control system. An RC5 code is 14 bits long. Each code includes a
5-bit address (or system) and a 6-bit command. Sharp uses a different IR protocol,
but some of their codes are acceptable.
NOTE: The Philips Pronto contains built-in RC5 commands for out-of-the-box use.
Setting up a Philips Pronto is easy! If using the Philips Pronto, select RC5 code communication. For the Philips Pronto,
the RC5 system number is equivalent to Crestron's Transmitter ID code, which is a
unique identifier assigned to each transmitter. Likewise, RC5 command number is
equivalent to Crestron's Button ID, which is synonymous with the join number used
in SIMPL Windows. There is no need to perform the two multi-step procedures in
the subsequent sections.

Crestron CNXRMCLV Room Solution Box with Local Video
Operations Guide – DOC. 8161A Room Solution Box with Local Video: CNXRMCLV •15
NOTE: Typically, codes used by Magnavox, Marantz, and Philips audio/video
equipment utilize RC5 codes for transmission. Some codes used by Sharp
Electronics Corporation are also usable.
Universal remotes require two
multi-step procedures for setup. Some devices from Magnavox, Marantz, and Philips are designed to understand
certain kinds of infrared signals sent by remote controls, specifically, signals
belonging to the RC5 code set. Two procedures are required to setup a universal
remote. The first procedure verifies that the universal remote chosen does transmit
an identifiable code and therefore can communicate with the CNXRMCLV. The
second procedure maps the buttons on the universal remote so that they can be used
in the SIMPL Windows program.
Code Verification
Refer to the note on page 26 for a
definition of Viewport.
Each universal remote comes with its own manual, which lists codes by device and
manufacturer. The purpose of this procedure is to select and program a code into the
universal remote so that it can communicate with the CNXRMCLV. All that is
required to complete this procedure is the CNXRMCLV, a Crestron CNXRMIRD, a
PC running the Crestron Viewport, a Crestron control system connected to the PC,
and any universal remote (complete with batteries and manufacturer's manual). The
control system should be running a valid SIMPL Windows program that includes
the CNXRMCLV (at the proper Net ID so that the CNXRMCLV can be polled) and
a CNXRMIRD. (For details on including the CNXRMIRD in the program, refer to
“Receiver” on page 21.)
1. Attach the CNXRMIRD to the CNXRMCLV (IR IN port).
2. Using Cresnet cable, attach the Crestron control system to the
CNXMRCLV (NET port). Refer to "Network Wiring" on page 8 for
details.
3. Open the Crestron Viewport.
Either launch the stand-alone version of Viewport, or start SIMPL
Windows and from the menu bar, select Tools | Viewport.
4. From the Viewport menu, select Diagnostic | Identify Transmitter
ID. The software checks the baud rate and then opens the "Transmitter
Identification" window, as shown after this step.

5. Point the universal remote at the CNXRMIRD and program the remote
with an RC5 code (some Sharp codes are acceptable as well) as
outlined in the manufacturer's manual.
NOTE: Crestron recommends that codes from manufacturers other than the
manufacturer of the device being controlled be used to avoid IR transmission
conflict. For example, if the controlled device is a Sony DVD player, an acceptable
code from any manufacturer (except Sony) should be used to communicate with the
Sony DVD player via the CNXRMCLV.

6. Select one or more function buttons on the remote and observe the
"Transmitter Identification" window on the PC.
a) If there is no activity while pressing buttons on the remote, the
code chosen was not an acceptable code. Repeat steps 5 and 6 with
another code.
b) If activity is observed with each button press, the code used was an
acceptable code and the CNXRMCLV can accept commands from
the universal remote.
Map the Universal Remote
Once communication between the CNXRMCLV and the universal remote is
achieved, it is necessary to understand what commands are transmitted and to which
devices. Crestron distinguishes each device with a unique hexadecimal number
known as the Transmitter ID that can range from 00 to 3F. Actually, RC5 codes
display these IDs in the range of 00 to 1F and Sharp codes of suitable format display
Transmitter ID codes in the range of 20 to 3F. Transmitter ID codes are revealed in
the "Transmitter Identification" window.
Each universal remote has a number of source selection buttons on it (i.e., TV, VCR,
DVD, AUX). Typically, those buttons are used when setting up the remote with an
acceptable code (refer to "Code Verification" on page 15). If an acceptable code is
transmitted during that procedure, Crestron assigns the code with an identifier in the
"Transmitter Identification" window. For example, in the window shown below, the
Transmitter ID (Hex): field shows the number 13. Since the identifier falls in the
range of 00 to 1F, the device communicates using an acceptable RC5 code.
Positive Transmitter Identification
The next logical question is, "What is the Button ID?" The purpose of this next
procedure is to map the buttons on the universal remote so that a list can be
generated and used for reference when creating the SIMPL Windows program. A
decimal identification number (or Button ID (Decimal) as shown in the "Transmitter
Identification" window) corresponds to each physical press on the universal remote.
This procedure picks up where the code verification procedure left off.
1. Complete steps 1 through 6 in "Code Verification" on page 15.
2. Wherever convenient (i.e., Notepad on the PC or a piece of scrap
paper) create a table for recording the Button ID (Decimal) number
associated with each button press on the universal remote. "Appendix:
Mapping Table" on page 34 contains a table to record this information.
Create as many copies of the table as necessary.
3. Click the Clear button in the "Transmitter Identification" window to
reset the setup.
