Crestron TPS-4500IMW Wall-Mounted Interface Module
Wall-Mounted Interface Module:
TPS-4500IMW
Description
Functional Description
The TPS-4500IMW is designed specifically to serve as an optional
interface module for the Crestron TPS-4500 tilt touchpanels. The module
provides a clean, 1-gang mountable interface for direct connection to the
touchpanel. The TPS-4500IMW creatively hides most of the connections
behind the wall. A visible RJ45 connector can be camouflaged with a
decora wallplate (not supplied) so that the unit blends into any setting.
Physical Description
The TPS-4500IMW, shown on the next page, is an option (can be
purchased separately). The unit mounts into a 1-gang electrical box
(recommended 2.5" depth). The back of the unit is silk-screened and
provides a network and video input connectors. Once installed, there is
only one RJ45 connector visible, which provides connection to the
touchpanel (cable, CA15859, supplied with touchpanel).
I/O Ports
There are four I/O ports available on the TPS-4500IMW. Details of each
are provided as bulleted items on page 3.

• COMP Y and C – These two (four-pin) ports on the back of
the unit provide connection for a video source. The unit can
accept either a single signal over one wire (composite video or
COMP) or two separate signals: one for brightness (luminance
or Y), and the other for color (chrominance or C). The port is
made active with the purchase and installation of the TPS-VID,
composite and S-video input TV video card, into the
touchpanel. Consult the latest revision of the TPS-VID
Operations & Installation Guide (Doc. 5869) for details.
NOTE: Except for differential input (balanced) video signal, the two
(four-pin) video connectors with jumpers should be installed at all times.
Refer to "Hardware Hookup" on page 5 for jumper details.
• NET – This four-pin connector is used to connect to other
four-wire devices in the Cresnet system. If making network
connections to Cresnet peripherals, refer to "Network Wiring"
on page 4 for details.
• NET/VIDEO – This 10-position RJ45 mates with the
TPS-4500 touchpanel and has a dual purpose. Refer to the
descriptions and pinout table that follow this paragraph.
1. This port provides network and power connection to the
touchpanel.
2. This port also makes available composite or S-video input for
TV video card (with the purchase and installation of the
TPS-VID). Consult the latest revision of the TPS-VID
Operations & Installation Guide (Doc. 5869) for details.

Leading Specifications
The table below provides a summary of leading specifications for the
TPS-4500IMW. Dimensions and weight are rounded to the nearest
hundredth unit.
Leading Specifications for the TPS-4500IMW
SPECIFICATION DETAILS
Video Input Impedance 75 Ohms (with jumper)
100 Ohms (without jumper)
Dimensions Height: 4.27 in (10.85 cm)
Width: 2.51 in (6.36 cm)
Depth: 1.49 in (3.77 cm)
Weight 0.32 lb (0.14 kg)
As of the date of manufacture, the TPS-4500IMW has been tested and
found to comply with specifications for CE marking.
Setup
Network Wiring
NOTE: When making wire connections, refer to the latest revision of
the Cresnet Network Interconnect Drawing (Doc. 5411). The document
can be obtained from the Downloads page (CABLES and MANUAL
Libraries) of the Crestron website (www. crestron.com). Search for the
CRESNET.PDF files.
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 load factor of each network unit to be daisy-chained must
be added together to determine the load factor of the entire chain. The
length of the run in feet and the load 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 following table).
L = Length of run (or chain) in feet.
LF = Load factor of entire run (or chain).
R < L x LF
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
table after this paragraph.

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 network units, always twist the ends of the
incoming wire and outgoing wire which share a pin on the network
connector. After twisting the ends, tin the twisted connection with solder.
Apply solder only to the ends of the twisted wires. Avoid tinning too far
up or the tinned end becomes brittle and breaks. After tinning the twisted
ends, insert the tinned connection into the network connector and tighten
the retaining screw. Repeat the procedure for the other three network
conductors.
Hardware Hookup
Connections to the Back of the TPS-4500IMW
The TPS-4500IMW serves as an optional 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 the CNX Generation control system or Cresnet
peripherals, refer to "Network Wiring" on page 4 for details. It is not
necessary to make connections to a video source unless the TPS-VID has
