Interface Module: TPMC-CH-IMC
Introduction
Features & Functions
The TPMC-CH-IMC is an interface module designed for, and included
with the Crestron TPMC-15-CH and TPMC-17-CH tilt touchpanel media
centers. The interface module expands the configuration possibilities of
the TPMC-15-CH and the TPMC-17-CH by allowing unbalanced video
signals (via BNC) and balanced/unbalanced audio signals to be
connected to the touchpanel’s CAT5 inputs and outputs. This device can
also be used to convert sources to CAT5 for use with other Crestron
CAT5 devices such as the CNXRMCLV Enhanced Room Solution Box.

Interface Module Crestron TPMC-CH-IMC
Physical Description
The TPMC-CH-IMC, shown in the following diagram, is supplied with
the TPMC-15-CH and TPMC-17-CH tilt touchpanel media centers. The
module is housed in a black enclosure with a silk-screened top panel. A
Light Emitting Diode (LED) indicating power, a network connector, and
connectors for video input, audio input, and audio output are located on
one side of the unit. The opposite side provides an RJ-45 video output
connector, an RJ-45 audio input/output connector and a network
connector to the touchpanel. The TPMC-CH-IMC also has a mounting
flange to secure the unit to a mounting surface or the rear of a rack. A
15-foot (4.6 meter) “triamese” cable with connections for network
communications and CAT5 audio and video to the touchpanel is included
with the TPMC-15-CH and TPMC-17-CH touchpanels.

Industry Compliance
As of the date of manufacture, the TPMC-CH-IMC has been tested and
found to comply with specifications for CE marking and standards per
EMC and Radiocommunications Compliance Labelling.
NOTE: This device complies with part 15 of the FCC rules. Operation is
subject to the following two conditions: (1) this device may not cause
harmful interference, and (2) this device must accept any interference
received, including interference that may cause undesired operation.
Setup
Network Wiring
CAUTION: In order to ensure optimum performance over the full range
of your installation topology, Crestron Certified Wire, and only Crestron
Certified Wire, should be used. Failure to do so, may incur additional
charges if support is required to identify performance deficiencies as a
result of using improper wire.
CAUTION: Use only Crestron power supplies for Crestron equipment.
Failure to do so could cause equipment damage or void the Crestron
warranty.
CAUTION: Provide sufficient power to the system. Insufficient power
can lead to unpredictable results or damage to the equipment. Please use
the Crestron Power Calculator (www.crestron.com/calculators
calculate how much power is needed for the system.
CAUTION: Possible equipment damage if miswired.
) to help
NOTE: When installing network wiring, refer to the latest revision of
the wiring diagram(s) appropriate to your specific system configuration,
available from the Crestron website.

Crestron TPMC-CH-IMC Interface Module
NOTE: Do not power up system until all wiring is verified. Care should
be taken to ensure data (Y, Z) and ground (G) connections are not
crossed when connecting the TPMC-CH-IMC.
When calculating the wire gauge for a particular Cresnet run, the length
of the run and the Cresnet power usage of each Cresnet unit to be
connected must be taken into consideration. If Cresnet units are to be
daisy-chained on the run, the Cresnet power usage of each network unit
to be daisy-chained must be added together to determine the Cresnet
power usage of the entire chain. If the unit is a home-run from a Crestron
system power supply network port, the Cresnet power usage of that unit
is the Cresnet power usage of the entire run. The length of the run in feet
and the Cresnet power usage 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 P
Where:
R = Resistance (refer to the following table).
L = Length of run (or chain) in feet.
P = Cresnet power usage of entire run (or chain).
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.

Doubled CAT5
Tripled CAT5
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
Operations Guide - DOC. 6345 Interface Module: TPMC-CH-IMC • 9
Interface Module Crestron TPMC-CH-IMC
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) 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.
CAT5 Wiring
Category 5 (CAT5) wiring is a twisted pair cable designed for Ethernet
networks. These networks operate at speeds of up to 100 Megabits per
second (Mbps) using the 100baseT standard. Crestron takes advantage of
this specification for a variety of audio and video applications.
Crestron recommends using CresCAT, CresCAT-D, or CresCAT-Q
wiring solutions.
The following chart shows the maximum recommended cable lengths for
various signal formats.
Recommended Maximum Cable Lengths for Audio/Video via CAT5
FORMAT MAXIMUM DISTANCE
Composite 750 feet
S-Video 750 feet
Component 500 feet
Audio 1000 feet (balanced)*
* The maximum distance for CAT5 audio is limited to approximately 15 feet
when connecting the AUDIO OUT port to a device with an unbalanced input.
If the AUDIO OUT port connects to a device with balanced inputs or no
device is connected, the maximum cable length for CAT5 audio is 1000 feet.
For more information, refer to the latest version of the Crestron CAT5
Wiring Reference Guide (Doc. 6137).

The TPMC-CH-IMC serves as an interface between the touchpanel and
the Cresnet system. Refer to the illustration after this paragraph for
proper connections; apply power last. When making network connections
to a control system or Cresnet peripherals, refer to “Network Wiring” on
page 8. It is not necessary to make connections to a video source unless a
