INTRODUCTION
The all new TWISTER, MMTP SERIES, which includes three pieces
of equipment, an MMTP-100 COMPUTER/RGB TRANSMITTER,
an MMTP-200 COMPUTER RGB RECEIVER, and when required an
MMTP-300 1 X 8 HUB were designed for applications requiring the
transport of video over long distances on Cat 5 type cable.
The Receiver has an equalization control to permit fine tuning of the
displayed image.
Cable runs of up to 1000 feet are within the capabilities of the product.
The MMTP-200S skew compensating receiver option is recommended
in any image critical RGBHV application over 200 feet, and all RGBHV
applications over 500 feet. There are three, 16 position rotary switches
for RGB skew adjustment on this option.
The MMTP-300 HUB is available to drive up to eight additional
Receivers. Up to three hubs can be cascaded to expand out to additional
receivers. It includes a larger power supply to power all transmitters,
receivers and the Hub itself.
When this equipment is used the original signal will arrive at the far
end of the cable with an almost immeasurable amount of loss and / or
distortion.
FEATURES
• Computer compatible sychronizing circuitry
• HD-15 female connectors for the input and output
• CAT-5 connections are via RJ-45 Connectors (EIA/TIA-568B)
• Full cable equalization control for the output channel
• Compatible with all computer standards
• UL and CSA approved external power source (wall plug-in)
APPLICATIONS
• Boardrooms • Houses of Worship• Control Rooms
• Classrooms• Staging and Rental

Installation and Operation
Mount the units as appropriate for the particular installation. Install and
terminate the UTP cable, taking note of the following. The cable must
be terminated using the EIA/TIA-568B standard pairing. Where pos-
sible, the use of pre terminated, pretested cables is highly recommended.
If field termination is required, be sure to use a commercially available
cable tester to confirm the proper wiring. Miswired interconnect cables
can damage your Twister and void it’s warranty.
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. Using a low skew cable may eliminate the need for the
MMTP-200S skew compensated receiver in short and moderate length
systems.
Once the interconnect cables are tested, connect the system as per the
diagram and perform the final operation check.
Two different power supplies are specified depending on the type of
installation. Point to point systems using a single transmitter/receiver
require the smaller wall mounted supply. This supply may be connected
to either the transmitter or receiver in systems under 800 feet. In systems
over 800 feet using the MMTP-200S skew compensated receiver, the
supply must be connected to the receiver.
Multipoint distribution systems employing the MMTP-300 8 output hub
require the larger desktop style power supply. In this type of system the
hub distributes power to the transmitter and all receivers in the system.
MMTP-200S skew compensated receivers must be located less than 800
feet from the hub.

System Calibration
For best results the following test patterns will be required:
• A crosshatch pattern with one pixel wide vertical and one pixel
high horizontal lines.
• Standard SMPTE color bars.
• A full width one on/one off burst pattern.
These test patterns will need to be output from the source equipment
(computer, DVD player, etc.) that you intend to connect to the Twister
Transmitter.
If possible, perform a display calibration without the Twister by connect-
ing the source directly to the display device using a short (less than 25
foot) video cable. Use the burst pattern to set the display size, phase and
pitch as per the display manufacturers instructions. Most displays will
have an “auto sync” function that will get you close, but might require
some additional fine-tuning. Once the display is set, connect the source
and display to the Twister.
Set the “EQ” adjustment to the minimum (full CCW) setting. If using the
MMTP-200S skew compensated receiver, make sure the delay settings
for R, G, and B are all at “0” (fully CCW). Using the crosshatch test pat-
tern, slowly increase the EQ setting until the vertical lines are nearly as
bright as the horizontal lines. In general, you will have to set the vertical
lines a little dimmer than the horizontal or you will have too much peak-
ing. You can check for over peaking by using the SMPTE color bars and
looking for two or three overly bright vertical lines at the beginning of
each color transition. If this occurs, back the EQ pot off slightly.
Once you are happy with the EQ setting, set the delay skew if available.
The object of the delay skew adjustment is to merge the separate red,
green, and blue vertical lines into a solid white line. Using the crosshatch
test image, identify the left most color in each vertical line of the im-
age. Use the corresponding rotary adjustment on the Twister to merge
this color with the right most vertical line in the image. Then adjust the
remaining color to merge with the first two. Once you have adjusted the
skew, use the burst pattern to fine-tune the display phase adjustment.
These last two steps may be repeated to optimize the image quality.
DC Restoration Jumpers
The MMTP-100 transmitter is equipped with DC restoration for compat-
ability with AC coupled sources. This feature relies on the presence of
a TTL compatible H sync signal applied to the H sync input pin (pin 13
of the HD-15 input connector). If you are transmitting a signal that does
not have a TTL H sync signal, you must disable the DC Restore circuit by
setting the three jumpers inside the transmitter as shown in the diagram
below. With the power to the unit dis-connected, simply remove the two
cover screws and cover on the MMTP-100 transmitter to access the three
jumpers.
