Where possible, the use of pre terminated, pretested cables is highly rec-
ommended. If fi eld termination is required, be sure to use a commercially
available cable tester to confi rm the proper wiring.
While Cat 5/5E cables are the most commonly used with the system,
other types of UTP cable can be used successfully. One of the most im-
portant cable parameters affecting the image quality of component video
systems (RGB/RGBHV/YUV, etc.) transmitted over the Twister is delay
skew. Delay skew in a cable will result in a loss of color convergence at
the display.
The use of generic CAT 5/5E/6 cable will generally give acceptable
results in short to medium length applications (up to 300’). For longer
distances, or where the highest image quality is paramount, use the skew
compensated model receivers. USE OF BELDEN NANOSKEW OR
OTHER NON-CATEGORY CABLE IS NOT RECOMMENDED. The
crosstalk on these types of cables is very high resulting in poor color
isolation, and video noise from the audio transport channel.
Once the interconnect cables are tested, connect the system as per the
diagram and perform the fi nal operation check.
LED SIGNAL STATUS INDICATION (TRANSMITTERS AND
RECEIVERS)
POWER/VIDEO
GREEN: Unit receives power, on-board
voltage regulator is operational, unit
receives video signal.
AMBER: Unit receives power, on-board
voltage regulator is operational, no video
source is connected or source is off.
(RGBHV sources only))
DATA
GREEN: RS232 activity (blinking)
YELLOW: IR activity (blinking)
POWER FAULT
OFF: Unit receives power from the remote
source.
GREEN: Unit receives power from the
local source.
RED: Power supply overload possibly due
to the miswired UTP cable. Check and
correct UTP connection.

RS-232 Installation
Connect the RS-232 output of the PC or control system to the TPRO
transmitter module to the “SERIAL IN” port. Connect the peripheral to
the TPRO “SERIAL OUT” DB-9 male port. (See pinout).
IR Control Installation
Confi rm and observe polarity on all external devices before proceed-
ing.
An integrated IR sensor is provided on all TPRO transmitter models. If
an external IR input from a control system is required, connect the IR
output device to the 3.5mm jack or 3 pin pluggable screw down terminal
connector (depends on model) on the TPRO Transmitter using the wiring
diagram provided.
Connect the IR emitter(s) to the 3.5mm jack or 3 pin pluggable screw
down terminal connector (depends on model) on the TPRO Receiver us-
ing the wiring diagram provided. Emitters are available from FSR. (Use
FSR IR-EC1-6 single or IR-EC2-6 dual emitter accessory.)
Once the interconnect cables are tested, power up the link and perform a
fi nal operation check.
Audio wiring:
See the pinouts for wiring details.
Connect the audio source to the TPRO Transmitter via the 3.5mm stereo
audio jack or 3 pin pluggable screw down terminal (depends on model)
on the face of the unit. Connect the TPRO Receiver’s 3 pin pluggable
screw down terminal or RCA jacks (depends on model) audio output to
the house sound system.
System Calibration and Adjustments
Setting the Boost Switch:
The Boost” switch is located on the right front of the TPRO receiver unit.
For Cat5 cable runs less than 200’, leave the “Boost” dip switch in the
OFF (UP) position. For 200-1000’ runs place the “Boost” dip switch in
the ON (DOWN) position.
System Calibration setup:
For best results the following test patterns will be required:
• A crosshatch pattern with one pixel wide vertical and one pixel
