Crestron TPS-4500IMPC Interface Module
Interface Module: TPS-4500IMPC
Introduction
Features & Functions
The TPS-4500IMPC is an interface module designed for, and included
with the Crestron TPS-4500 and TPS-4500V tilt touchpanels. The sleek
design of the touchpanel base left little room for all the connectors that
define the touchpanel's versatility. Furthermore, since the panel is not a
stationary user interface, it is impractical to have an excessive number of
cable connections directly to the touchpanel. As a result, it was necessary
to connect the touchpanel to an interface module that could offer
additional space for interconnections.
Specifications
The following table provides a summary of specifications for the
TPS-4500IMPC.

Physical Description
The TPS-4500IMPC, shown in the following diagram, is supplied with
the TPS-4500 and TPS-4500V tilt touchpanels. The module is housed in
a black enclosure with labeling. An AC adapter port, network connector,
and video input connectors are located on one side of the unit. The
opposite side provides a video input signal selector switch, and
network/video connections to the touchpanel. The TPS-4500IMPC also
has mounting feet to secure the unit to a mounting surface.

Crestron TPS-4500IMPC Interface Module
NTSC/PAL VIDEO
The NTSC/PAL video input consists of three connectors; two BNC
connectors for unbalanced video signals and one 6-pin mini-connector
for twisted pair wiring of balanced video signals. The video signal is
connected to these ports and requires a TPS-4500V or installation of the
TPS-VID-1 or TPS-VID-2 video card in a TPS-4500 touchpanel to
display video. Consult the latest revision of the TPS-4500V & 4500LV
Operations Guide (Doc. 6160), TPS-4500 & 4500L Operations Guide
(Doc. 5891), or TPS-VID-1/2 Operations & Installation Guide (Doc.
6059) for details. Use either the two BNC connectors or the six-pin
connector for twisted pair wiring when connecting a video source.
NOTE: BNC connectors are physically located next to the twisted pair
connectors. Image is for illustration purposes only. Refer to the physical
view of the TPS-4500IMPC on page 2 for actual connector positions.
NOTE: The TPS-4500IMPC allows the use of either balanced or
unbalanced signals for video input. To select the signal type to be used,
the DIP switches located on the opposite side of the device must be set in
the correct position. Refer to “BAL/COAX” on page 5 for more
information.

This four-pin connector is used to connect to a Crestron control system
and other Cresnet peripherals in a system. It also provides network power
to the touchpanel if an external power pack is not used. If making
network connections to a control system or Cresnet peripherals, refer to
“Network Wiring” on page 5.
24 VDC, 2.0A (Power Supply)
24VDC
2.0A
This female connector is used to supply 24 VDC power to the
TPS-4500IMPC and the touchpanel from an optional power pack
(Crestron model PW-2420RU). When power is supplied to the TPS-
4500IMPC through this connector, a Cresnet power connection is not
required to display video on the touchpanel.
CAUTION: Use only Crestron power supplies for Crestron equipment.
Failure to do so could cause equipment damage or void the Crestron
warranty.

Interface Module Crestron TPS-4500IMPC
CAUTION: If power is provided to the TPS-4500IMPC from the
+24VDC on a Cresnet connector or the PW-2420RU, power must not be
applied to the power input on the touchpanel base.
NOTE: When power is supplied through this connector, Crestron
recommends disconnecting the +24 VDC on the Cresnet connector (if it
is connected).
NOTE: Use care in wiring installations to avoid applying 24 VDC power
to Cresnet wiring from multiple sources.

This 10-pin RJ-45 connection mates with the TPS-4500 or TPS-4500V
touchpanel. Refer to the descriptions and pinout table that follow this
paragraph. The 10-pin net/video cable assembly to connect the
touchpanel to the TPS-4500IMPC is supplied.
This port provides the Cresnet connection to the touchpanel. This port
also provides composite or S-video input for the built-in video card (with
the purchase of a TPS-4500V or installation of the TPS-VID-1/2 in a
TPS-4500 touchpanel). Consult the latest revision of the TPS-4500V &
4500LV Operations Guide (Doc. 6160), TPS-4500 & 4500L Operations
Guide (Doc. 5891), or TPS-VID-1/2 Operations & Installation Guide
(Doc. 6059) for details.

Crestron TPS-4500IMPC Interface Module
CAUTION: The 10-pin RJ-45 net/video connector cable supplied by
Crestron is a custom cable and is the only one that should be used. The
end of the cable has a metal shield that is required to protect the
equipment. Using non-Crestron cables will result in damage to the
product.
BAL/COAX
While not a port, these DIP switches are used to select which video
connections (balanced or unbalanced) to use when receiving video
signals. When used with a TPS-4500 with TPS-VID-2 installed, each
composite video signal can come in on either the twisted pair (balanced)
or coaxial (unbalanced) connector. When used with a TPS-4500V or
TPS-4500 with TPS-VID-1 installed, the video signal (S-video or
composite) can be received over the twisted pair (balanced) or coaxial
(unbalanced) connectors. As long as a switch is in the appropriate
position, a signal can be connected to either the BNC or twisted-pair
connector.
To select the twisted pair connector for balanced video, the DIP switch
for the respective video source must be in the “UP” position. To use the
coaxial connector(s) for unbalanced video, the DIP switch must be in the
“DOWN” position.
Industry Compliance
As of the date of manufacture, the TPS-4500IMPC has been tested and
found to comply with specifications for CE marking and standards per
EMC and Radiocommunications Compliance Labelling (N11785).

CAUTION: Use only Crestron power supplies for Crestron equipment.
Failure to do so could cause equipment damage or void the Crestron
warranty.
Operations Guide - DOC. 6163 Interface Module: TPS-4500IMPC •5
Interface Module Crestron TPS-4500IMPC
CAUTION: Possible equipment damage if miswired.
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).
NOTE: Do not power up system until all wiring is verified. Care should
be taken to ensure data (Y, Z) and power (24, G) connections are not
crossed.
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: 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.
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
following table.
