QuickMedia™ Receiver/Processor Crestron
QM-RMCRX-BA
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 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 Crestron website (http://www.crestron.com/manuals).
NOTE:
For larger networks (i.e., greater than 28 network devices), it may be
necessary to add a Cresnet Hub/Repeater (CNXHUB) to maintain signal quality
throughout the network. Also, for networks with lengthy cable runs or varying
types of network devices, it may be desirable to add a hub/repeater after only 20
network devices.
QM Network Wiring
When connecting multiple QM devices, the route between a QM origination
point (e.g., QM-TX) and a QM endpoint (e.g., QM-RMCRX-BA) cannot have
more than two midpoints (e.g., QM-MD7x2 or other QM switchers). Refer to
the following diagram when configuring a QM network. The aggregate length
from transmitter to receiver cannot have a delay skew of more than 22 ns.
NOTE:
Refer to Appendix B on page 65 for detailed auto-compensation
information.
QM Network Topology
Mounting
The QM-RMCRX-BA can be mounted using the included four mounting
brackets. Attach the included brackets using the existing cover screws located on
the sides of the QM-RMCRX-BA as shown in the following diagram.
