Setup
Network Wiring
NOTE: When installing network wiring, refer to the latest revision of the wiring
diagram(s) appropriate to 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 Cresnet 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 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.

NOTE: All network wiring must consist of two twisted pairs. One twisted pair is
the +24V conductor and the GND conductor. The other twisted pair is the Y and Z
conductors.
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.
NOTE: For larger networks (i.e., greater than 28 network devices), it may become
necessary to add a Cresnet Hub/Repeater (CNXHUB) or Cresnet Network Poll
Accelerator (C2N-NPA8) to maintain signal quality throughout the network. Also,
for networks with lengthy cable runs, it may be necessary to add a Hub/Repeater
after only 20 devices.
QuickMedia Wiring
The Crestron QuickMedia cable (sold by Liberty Wire and Cable under the name
“Crescat-QM”) contains one CAT5E cable and one Cresnet cable in siamese jackets.
Installation of any QM device is as simple as installing one set of QM wires from the
output of one device to the input of another. Installations are flexible, affordable, and
fast.
CRESCAT-QM Cable
Operations Guide - DOC. 6260 QuickMedia Distribution System: QM-MD8x8 •11

QuickMedia Distribution System Crestron QM-MD8x8
NOTE: Do not untwist the two wires in a single pair for more than 1/3-1/2” (0.84 –
1.27 cm) when making a connection. The twists are critical to canceling out
interference between the wires.
The QM transport mechanism (receiver) uses frequency compensation on each
twisted pair video input to maintain high resolutions (1600 x 1200) with CRESCAT-
QM cable (which contains both Cresnet and CAT5E wiring) and most good quality
CAT5E and CAT6 cables (where skew rating is ≤15 ns / 100 meters). The total
accumulated length of the cable determines the actual skew. For example, when
connecting the QM-WMC to a QM-MD8x8 and then to the QM-RMCRX, the total
accumulated skew must not exceed 15 ns.
NOTE: The length of CAT5/5E/6 cable that can be used can vary. However, the
total skew must be ≤15 ns.
NOTE: Longer lengths of cable may experience eventual loss of bandwidth when
viewing higher resolution sources.
The following diagram illustrates how composite, S-video, and RGB video signals
are transmitted over the CAT5E wire.
Quick Media Video Signals on CAT5E
NOTE: When transmitting S-video or composite video, luminance uses the green
video pathway, chrominance uses the red video pathway, and composite uses the
blue video pathway.
The pin assignments for Crescat-QM, CAT5, CAT5E, and CAT 6 wiring are based
on the EIA/TIA 568B RJ-45 Jack standard.

Identity Code
All equipment and user interfaces within the network require 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 21 for details of the SIMPL
Windows procedure.
Refer to the note on page 24 for a
definition of Viewport.
The Net ID of the MD8x8 has been factory set to 06. The Net IDs of multiple
MD8x8s 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 25. If communication
cannot be established, refer to the “Troubleshooting Communications” section in the
respective Operations Guide for the control system.
There are two different methods—Method A or Method B—for setting the Net ID:
Method A (Cresnet address-settable ID), described below, applies to devices in a
Cresnet system with a 2-Series control system that require a single unit be the only
network device connected to the control system.
Method B (Touch Settable ID or TSID), which begins on the following page, applies
to all TSID-ready devices in a Cresnet system with 2-Series control system upgrade
file (CUZ) version 3.029 or later. TSID functionality makes it possible for the
control system to recognize a network device via its serial number, which is stored in
the device’s memory. This method does not require that any devices be disconnected
from the network; Net IDs may be set with the entire Cresnet system intact. This
method requires the use of the Crestron Viewport version 3.35 or later.
Use the appropriate method to set the Net ID.
Method A (Cresnet address-settable 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.

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.
Method B (Touch Settable ID)
Before using this method, you should have a list of all current network devices and
their Net IDs, to avoid assigning duplicate IDs.
Set Net ID by TSID
These procedures are for TSID-enabled network devices during the initial
configuration of a Cresnet system or when such devices are being added/replaced.
1. Ensure that all network devices are connected to the control system.
2. Open the Crestron Viewport version 3.35 or later.
3. From the Viewport menu, select Functions | Assign Cresnet ID by Serial
Number. The “Set Net ID by TSID” window appears. The window is first
displayed with the data fields empty.
4. Click on the Search for Touch Settable Devices button. The system
searches the network and lists all TSID-enabled devices found. The list is
similar to the report produced by pressing F4 (Report Network Devices);
the first eight digits of each line constitute the TSID number (hexadecimal
form of the serial number).

 If the rack is provided with stabilizing devices, install the stabilizers before
mounting or servicing the unit in the rack.
NOTE: If rack mounting is not required, rubber feet are provided for tabletop
mounting or stacking. Apply the feet near the corner edges on the underside of the
unit. Refer to “Stacking” on page 17 for details.
NOTE: Reliable earthing of rack-mounted equipment should be maintained.
Particular attention should be given to supply connections other than direct
connections to the branch circuit. (e.g., use of power strips).
Two “ears” are provided with the MD8X8 so that the unit can be rack mounted.
These ears must be installed prior to mounting. Complete the following procedure to
attach the ears to the unit. The only tool required is a #1 Phillips screwdriver.
1. There are screws (#4-40 x 0.3125" LG) that secure each side of the
MD8X8 top cover. Using a #1 Phillips screwdriver, remove the three
screws closest to the front panel from one side of the unit. Refer to the
diagram following step 3 for a detailed view.
2. Position a rack ear so that its mounting holes align with the holes
vacated by the screws in step 1.
