Introduction
About this Manual
This manual describes how to install, configure, and operate the Extron IN1502
video scaler and how to operate the optional IR 901 infrared remote control
(part #70-152-01).
Throughout this manual the terms “IN1502”, “video scaler”, and “scaler” are
used interchangeably to refer to the same product.
About the IN1502
What is the IN1502?
The IN1502 is a video scaler that offers 16 output rates and provides scaling
solutions for boardrooms, conference rooms, and home theaters, as well as rental
and staging applications.
To enable superior scaling performance, the IN1502 features several of Extron’s
patented and patent-pending technologies, including Dynamic Motion
Interpolation (DMI
advanced motion detection and compensation method that enables image
enhancement with no loss of image fidelity.
The IN1502 scales composite video and S-video up to computer video (RGBHV/
RGBS), which can be output to a display device via a 15-pin HD connector.

) technology, and 3:2 and 2:2 pulldown detection. DMI is an
Controlling the IN1502 video scaler
The IN1502 can be controlled using one or more of the following methods:
• The front panel controls
• A computer, a touch screen panel, or any other device that can send and
receive the serial communications through the RS-232 port. Extron’s
Simple Instruction Set (SIS
can be used with any such devices.
• The optional IR 901 remote control, which has most of the front panel controls
Features and Options
Features
Two video inputs
• Input 1 — One BNC connector on the rear panel accepts a composite video
signal.
• Input 2 — One 4-pin DIN connector on the rear panel accepts an S-video
signal.
Video output — One VGA-type 15-pin HD connector provides an RGB output.
Three ways to control the scaler — The scaler’s front panel, a computer or other
RS-232 control device, or the optional IR 901 remote control can all be used
to control the scaler.
Scaled outputs — The IN1502 offers 16 different output rates.
RS-232 configuration — The IN1502 can be configured by using a control
system.
Dynamic Motion Interpolation (DMI) — This video processing technique is an
advanced motion prediction and compensation method that treats motion
content and still content with different algorithms to yield high fidelity
images.

3:2 pulldown detection for NTSC and 2:2 film detection for PAL video
sources — These advanced film mode processing features help maximize
image detail and sharpness for video sources that originated from film.
When film is converted to NTSC video, the film frame rate has to be
matched to the video frame rate in a process called 3:2 pulldown. Jaggies
and other image artifacts can result if conventional deinterlacing
techniques are used on film-source video. The IN1502’s advanced film
mode processing recognizes signals that originated from film. The
IN1502 then applies video processing algorithms that optimize the
conversion of video that was made with the 3:2 pulldown process. This
results in richly detailed images with sharply defined lines. A similar
process is used for PAL film-source video.
Versatile mounting options — The IN1502 is 1U high, and a half rack wide. It is
rack mountable, or it can be placed on a table or other furniture. Rubber
feet are included.
Options and accessories
The IN1502’s optional equipment includes:
• IR 901 remote control — Extron’s IR 901 (part #70-152-01) is an infrared
remote control which replicates all of the front panel controls of the
IN1502 except the Menu and Next buttons.
• Rack shelf mounting kit — The 1U high, half rack width IN1502 can be rack
mounted using the universal rack shelf mounting kit (part #60-190-01) or
the basic rack shelf mounting kit (part #60-604-01).

UL rack mounting requirements
The following Underwriters Laboratories (UL) requirements pertain to the safe
installation of the IN1502 in a rack.
1. Elevated operating ambient temperature — If installed in a closed or
multi-unit rack assembly, the operating ambient temperature of the rack
environment may be greater than room ambient temperature. Therefore,
install the IN1502 in an environment compatible with the maximum
ambient temperature (Tma = +113 °F, +45 °C) specified by Extron.
2. Reduced air flow — Install the equipment in a rack so that the amount of
air flow required for safe operation of the equipment is not compromised.
3. Mechanical loading — Mount the equipment in the rack so that a
hazardous condition is not achieved due to uneven mechanical loading.
4. Circuit overloading — Connect the equipment to the supply circuit and
consider the effect that circuit overloading might have on overcurrent
protection and supply wiring. Appropriate consideration of equipment
nameplate ratings should be used when addressing this concern.
5. Reliable earthing (grounding) — Maintain reliable grounding of rack-
mounted equipment. Pay particular attention to supply connections other
than direct connections to the branch circuit (e.g. use of power strips).
Tabletop/desktop placement
For tabletop or desktop placement only, install the self-adhesive rubber feet/pads
(provided) onto the four corners of the bottom of the enclosure.
Rack mounting
1. If feet were installed on the bottom of the IN1502, remove them.
2. Place the IN1502 on one half of the 1U (one unit high, one unit wide) rack
shelf (part #60-190-01 or #60-604-01). Align the front of the IN1502 with
the front of the shelf, and align the threaded holes on the bottom of the
IN1502 with the holes in the rack shelf.
3. Attach the IN1502 to the rack shelf with the two provided 4-40 x 3/16"
machine screws. Insert the screws from the underside of the shelf, and
securely fasten them into diagonally-opposite corners.
See the following illustration.

The Remote connector also provides a way to select an input using a remote
contact closure device. Contact closure control uses pins on the Remote
connector that are not used by the RS-232 interface (see preceding the table).
To select a different input number using a contact closure device,
momentarily short the pin for the desired input number to logic ground
(pin 5). To force one of the inputs to be always selected, leave the short to
logic ground in place. The short overrides front panel input selections.

Optimizing the System for a DVD Player
For optimal performance, follow the steps in this section in order when setting
up the IN1502 for a DVD player.
Setting up a DVD source
To get the best results when using a DVD as a video source, Extron recommends
that the DVD player itself be set up to output an aspect ratio of 16:9 and not 4:3.
Because all DVDs are mastered as 16:9, having them set up for anything else will
cause the player to internally scale and compress the signal. This scaling/
compression by the DVD player will defeat the advantage of having 3:2
pulldown detection in the IN1502.
All sizing adjustments to correct aspect ratio should be done using the IN1502.
To change the output aspect ratio of most DVD players,
1. Enter the DVD player’s Setup or Action menu while the disc is stopped.
2. Select a 16:9 aspect ratio.

Troubleshooting
This section gives recommendations on what to do if you have problems
operating the IN1502, and it provides examples and descriptions for some image
problems you might encounter.
The following are some tips to help you in troubleshooting.
1. Some symptoms may resemble others, so you may want to look through all
of the examples before attempting to solve the problem.
2. Be prepared to backtrack in case the action taken doesn’t solve the problem.
3. It may help to keep notes and sketches in case the troubleshooting process
gets lengthy. This will also give you something to discuss if you call for
technical support.
4. Try simplifying the system by eliminating components that may have
introduced the problem or made it more complicated.
5. For sync-related problems: Portable digital projectors are designed to
operate close to the video source. Sync problems may result from using
long cables or from improper termination. A sync adapter, such as Extron’s
ASTA (active sync termination adapter), may help solve these problems.
6. For LCD and DLP projectors and plasma displays: In addition to the sync-
related information above, check the user’s manual that came with the
projector for troubleshooting tips, as well as for settings and adjustments.
Each manufacturer may have its own terms, so look for terms like “auto
setup”, “auto sync”, “pixel phase”, and “tracking”.

The IN1502 can be remotely controlled via a host computer or other device (such
as a control system) attached to the rear panel Remote connector. The control
device (host) uses Extron’s Simple Instruction Set (SIS) commands.
The scaler uses a protocol of 9600 baud, 1 stop bit, no parity, and no flow control.
The rear panel RS-232 9-pin D connector has the following pin assignments:

RS-232 Programmer’s Guide
Host-to-scaler communications
SIS commands consist of one or more characters per field. No special characters
are required to begin or end a command sequence. When the IN1502 determines
that a command is valid, it executes the command and sends a response to the
host device. All responses from the scaler to the host end with a carriage return
and a line feed (CR/LF = ), which signals the end of the response character
string. A string is one or more characters.
It is also possible to send several SIS commands back-to-back in sequence.
Scaler-initiated messages
When a local event such as a front panel selection or adjustment takes place, the
IN1502 scaler responds by sending a message to the host. No response is
required from the host. The scaler-initiated messages are listed here
(underlined).

firmware version number.

C hn
The IN1502 sends this response when an input is switched.
(where X1 is the input number)
Error responses
When the scaler receives a valid SIS command, it executes the command and
sends a response to the host device. If the IN1502 is unable to execute the
command because the command is invalid or it contains invalid parameters, it
returns an error response to the host.
The error response codes and their descriptions are as follows:
E01 – Invalid input channel number
E10 – Invalid command
E13 – Invalid value (the number is out of range/too large)

Firmware Upgrade Installation
In some cases, the IN1502’s firmware may require replacement with an updated
version. There are three user-replaceable firmware chips: U41 — the main
microcontroller, U38, and U17. The numbers are printed on the circuit board. We
recommend that you send the unit to Extron for service and updates.
Changes to firmware must be performed by authorized service personnel
only. Some IN1502 firmware updates must be performed at the Extron
factory.
Follow these steps to replace firmware in the scaler.
1. Disconnect the AC power cord from the IN1502 to remove power from the
unit.
To prevent electric shock or damage, always unplug the IN1502 scaler
from the AC power source before opening the enclosure.
2. Remove the scaler from the rack or furniture.
3. Remove the cover of the scaler (the top half of the enclosure) by removing
the four screws, then lifting the cover straight up.

Do not touch any switches or other electronic components inside the
scaler. Doing so could damage the scaler. Electrostatic discharge (ESD)
can damage IC chips even though you cannot feel it. You must be
electrically grounded before proceeding with firmware replacement. A
grounding wrist strap is recommended.
4. Locate the firmware chip(s) to be replaced on the circuit board, as shown in
the following illustration.

5. After you are electrically grounded, you can remove the U17 IC chip or U38
IC chip by grasping it firmly with your fingers and pulling it out; then
continue to step 8.
Removal of the U41 IC chip requires a PLCC IC puller
tool. To remove the U41 chip, align the hooks of a
PLCC IC puller tool with the slots located in opposite
ends of the U41 firmware chip.
6. Insert the hooks into the slots, and squeeze the tool
gently to grasp the chip.
7. Pull the chip straight out of the socket, and set it aside.
8. For U17 and U38, align the notch of the new firmware
chip with the notch of the socket in the same
orientation as the old chip.
For U41, align the angled
corner of the firmware
chip with the angled
corner of the socket.
9. Gently, but firmly, press
the chip into place in the
socket.
10. Replace the top cover on the IN1502 scaler, and fasten
it with the screws that were removed in step 3.
11. Rack or furniture mount the scaler, and reconnect the AC power cord.
