Crestron TPS-4500IMW
Resistance Equation
R < L x LF
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.
Wire Gauge Values
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
