Professional Video Distribution Switch Crestron CNX-PVID8x4
The CNX-PVID8x4 accepts digital audio, component, S-video, and NTSC/PAL
composite sources, including HDTV signals, and distributes them to display devices
throughout the home via standard CAT5 structured wiring. This distribution method
ensures a balanced signal for long runs, allowing the user to equalize, adjust, and
boost the gain of the video signal for the perfect picture for every application, in
every room.
The CNX-PVID8x4 is designed with three levels of video inputs and outputs, each
highly configurable for a variety of video formats. Each of the three levels of
switcher boards implements a video matrix with 16 RCA inputs and eight RCA
outputs for direct single ended video connection to local display devices. A fourth
level may be used for 16 channels of distributed digital audio. In addition, the
CNX-PVID8x4 contains eight RJ-45 outputs for distributing any of these
audio/video signals via CAT5 mode for differential audio/video to up to eight rooms
throughout the house. No matter what the configuration, all inputs have a built-in
video sync sensor that reports power/activity status of all source devices attached to
the CNX-PVID8x4.
CNX-PVID8x4 used with Crestron Room Solution Box
NOTE: Systems that incorporate the CNX-PVID8x4 and Crestron Room Solution
Boxes satisfy a vast number of possible applications that could be used by Crestron
customers.
The CNXPVID8x4 is ideally used in tandem with a CNXRMC or CNXRMCLV in
each room, which receives and decodes the CAT5 video from the CNX-PVID8x4
and supplies it to the display device in the room. Refer to an illustration of a general
application scenario after this paragraph. This video distribution solution, combined
with Crestron's audio distribution switches (CNX-PAD8A or CNX-BIPAD8), a
Crestron CNAMPX intelligent amplifier, and a 2-Series control system, creates a
complete networked audio/video/control solution for the connected home.

CNX-PVID8x4 used without Crestron Room Solution Box
In this system, the CNX-PVID8x4 has an incredible amount of flexibility with
respect to making connections to all three types of video sources. For example, it is
possible to have a composite source connected to INPUT 1, level 1 and an S-video
source connected to INPUT 1, levels 2 and 3, simultaneously. However, the Crestron
AppBuilder cannot be used for the programming portion of this kind of system. All
programming is done entirely in SIMPL Windows.

the following two conditions: (1) these devices may not cause harmful interference,
and (2) these devices must accept any interference received, including interference
that may cause undesired operation.
Setup
Network Wiring
CAUTION: Use only Crestron power supplies for Crestron equipment. Failure to
do so could cause equipment damage or void the Crestron warranty.
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 Cresnet run, the length of the run
and the power factor of each network unit to be connected must be taken into
consideration. If Cresnet units are to be daisy-chained on the run, the power factor of
each unit to be daisy-chained must be added together to determine the power factor
of the entire chain. If the unit is a home-run from a Crestron system power supply
network port, the power factor of that unit is the power factor of the entire run. 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 <
40,000
L x PF
Where:
R = Resistance (refer to table below).
L = Length of run (or chain) in feet.
PF = Power factor of entire run (or chain).

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 Cresnet units, strip the ends of the wires carefully to
avoid nicking the conductors. Twist together the ends of the wires that share a pin on
the network connector, and tin the twisted connection. Apply solder only to the ends
of the twisted wires. Avoid tinning too far up the wires or the end becomes brittle.
Insert the tinned connection into the Cresnet connector and tighten the retaining
screw. Repeat the procedure for the other three 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
program. Refer to “Setting the Net ID in Device Settings” on page 22 for details of
the SIMPL Windows procedure.
The Net ID of the CNX-PVID8x4 has been factory set to 41. The Net IDs of
multiple CNX-PVID8x4s 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 31. 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 CNX-PVID8x4 is the only device 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 CNX-PVID8x4 from the
Current Network Devices text window.
5. Select the new Net ID for the CNX-PVID8x4 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 CNX-PVID8x4 to be added to the
system.
Cabling and Jumpers
Out of the box, the CNX-PVID8x4 provides four 16x8 crosspoint boards that can be
operated independently or in parallel. However, versatility was built into the unit.
Depending on how the four boards are cabled and/or jumpered, the unit can be used
in different hardware configurations. For example, cabling boards 1 and 3
conceptually eliminates level 3 (thus component sources are not allowed with this
configuration) and extends level 1 with 16 composite-only connections. Furthermore,
installation of the cable assembly and removal of jumpers splits level 3 (thus
component sources are restricted to inputs 9 through 16) and extends level 1 with
eight composite-only connections.
NOTE: Possible configurations and their respective applications when the
CNX-PVID8x4 is connected to Crestron Room Solution Boxes are summarized in
"Hardware Configurations" on page 14. Furthermore, cabling and jumper removal
may prove useful in systems where the CNX-PVID8x4 does not connect to a
Crestron Room Solution Box.
If the out-of-the-box configuration is desired, the following procedure, which defines
how to install the cable and remove jumpers, need not be completed. If one of the
other configurations is required, the only tools needed to complete this procedure are
a #2 Phillips screwdriver and a grounding strap (grounded workstation).
CAUTION: The CNX-PVID8x4 contains ESD sensitive devices. Perform the
following procedure while wearing a grounding strap that is properly grounded or on
a grounded workstation to avoid damaging the unit.
NOTE: This procedure assumes that the CNX-PVID8x4 does not have rack ears
attached and has yet to be connected to the network.
1. Place the CNX-PVID8x4 right side up on a flat surface.
2. Using a #2 Phillips screwdriver, remove the 16 cover screws from the
top (four screws) and sides (six per side) of the CNX-PVID8x4.
3. Lift and remove the CNX-PVID8x4 top cover.
4. Use the supplied cable (15863) to connect board 1 (bottom board) to
board 3, as shown in the following diagram.
