1. Introduction

The Boxlight PRO80S3 Projector is a three-chip DLP projector with a native resolution of 1280x720 pixels (16:9 aspect
ratio). The projector accepts 720p video through a DVI-D connector on the rear panel.

1.1 Controllers

The projector is controlled by a pair of MTV312M64 microcomputers. The first is the main controller and is responsible for
lamp ballast and formatter initialization. It continuously monitors the state of the formatters, the ballast and the video input
primarily to prevent the lamp from extinguishing due to loss of video or unintentional resetting of the formatters due to
power fluctuations. Communication with the controller is through an RS-232 interface using a simple command/parameter
protocol. The second processor manages the IR remote control functions: lens shift, focus and zoom. It has no external
communications interface except the IR receiver.

1.2 Rear Panel Connectors, Switches and Displays

There are four I/O connectors, two switches and nine LEDs on the rear panel.

1.3 Power Sequencing

1.3.1 STANDBY

When the main power switch is turned ON, the projector comes up in STANDBY mode. It may be left in this state
indefinitely. Both controllers and the RS-232 circuitry are powered so that the unit can respond to serial commands, the IR
Remote Control or the rear panel switch. The ballasts, fans and formatters are not energized.

Note: The IR Remote POWER button is always active but the other buttons may be disabled. If the unit is powered up
using the IR Remote, all IR commands will be enabled. If the unit is powered up using the rear panel switch or via the
serial port, only the IR POWER button will be active. IR Remote buttons may be enabled or disabled with the IR+ and IR­serial commands.

The projector may then be powered UP or DOWN using any of the methods above. The rear panel switch is
multifunctional. The following operation description assumes that the main power switch is ON:

If the projector is in STANDBY, the multicolor LED to the left of the switch will glow RED and on the 8 LED status display,
the READY LED will be ON. (

may be flashing

the lamp and initializing the formatters. The multicolor LED will glow GREEN. The projector will come up in CURTAIN
projection mode with the shutter closed. The STATUS LEDs will display the progress of the power-up sequence. When all
of the LEDs except for the SHUTTER LED are lit, the shutter may be opened.

1.3.2 POWER ON

If the projector is POWERED UP, a momentary depression of the right side of the switch (1/2 second or more) will open
the SHUTTER and put the formatters in NORMAL PROJECTION MODE. Subsequent depressions will toggle between
NORMAL MODE/SHUTTER OPEN and CURTAIN MODE/SHUTTER CLOSED.

Depressing the left side of the rocker switch will cause the SHUTTER to close and the formatters to go to CURTAIN
MODE and also initiates a 5-MINUTE POWER DOWN cycle. During this time the lamp, fans and formatters remain active.
The multicolor LED will glow YELLOW (both the RED and GREEN are ON). The STATUS LEDs should all be ON except
for SHUTTER. If no other action is taken for the next 5 minutes, the projector will go through the 60 SECOND POWER
OFF sequence: the lamp is extinguished and the fans are left running for 60 seconds before going back to STANDBY. If
the shutdown was not due to some anomaly, e.g., a fan failure, all of the STATUS LEDs will be OFF. If there was an
anomaly, one or more may be flashing.

The READY LED will go OFF when the lamp is extinguished. It will go back ON after 90 seconds indicating that the lamp
may be re-struck. A command to re-strike via any of the three methods - serial, IR or switch – may be issued at any time
but the re-strike will not occur until the 90-second lamp cool-down has expired.

1.3.3 5 MINUTE POWER DOWN

If the projector is in the 5 MINUTE POWER DOWN sequence, a momentary depression of the left side of the switch (1/2
second or more) will initiate the 60 SECOND POWER OFF sequence. The 5 MINUTE POWER DOWN may be canceled
by issuing an ON or OPEN command through the serial port, by depressing the right side of the rocker switch or – if the IR
remote is enabled - depressing the BLANK button to open the SHUTTER. The multicolor LED will again glow GREEN.

1.3.4 60 SECOND POWER OFF

The 60 SECOND POWER OFF sequence first extinguishes the lamp, extinguishes the STATUS LEDs and resets the 90
second lamp cool-down timer. No re-strike will be permitted until it times out. If no further action is taken, after 60 seconds
the main power will be turned off – the fans go OFF - and the projector will be back in STANDBY.

Commands to restart the projector may be issued before the 60 SECOND POWER OFF sequence completes: serial ON
command, IR POWER button or left rocker switch. 60 SECOND POWER OFF will be canceled but the lamp will not re­strike until the 90 second cool-down period has expired. The POWR STATE LED will show GREEN.

.) Depressing the left side of the switch momentarily (1/2 second or more) will power up the unit, turning on

If there were any problems encountered during the previous power-on cycle, other LEDs

1.4 Serial Communications

The controller UART must service communications from two sources: the RS-232 interface via the DB-9 connector on the
rear panel and the NIC interface. The NIC card controls a multiplexed that switches the UART between these two sources.
The controller firmware services three different command sets: one from the NIC card (which is not specified in this
document) and two from the RS-232 port. These two will be referred to as

human

and

machine

commands. The

human

interface is a verbose natural language interface that is intended for manufacturing and maintenance operations via a PC
running a terminal program attached to the port. Incoming character are typically echoed back to the terminal and a variety
of status messages are routinely sent, especially during power-up up and down sequences and when system anomalies
are detected and corrected. The

machine

interface is a terse command set. Incoming characters are not echoed and no

data is sent to the host unless requested.

The controller’s UART is selectable at 9600 or 19200 baud, 8-bits, no parity and 1 stop bit. The receiver is interrupt driven
with a 64 byte queue. The transmitter is polled and has no queue. XON/XOFF (^Q/^S) flow control is implemented in both
directions. The DB9-F connector is wired as a standard PC computer peripheral and may be connected to a PC running
an ASCII terminal program with a straight-through serial extension cable – not a null-modem.

1.5 Film Projector Lockout

The film projector lockout feature uses an external signal control either turning the projector on/off or closing/opening the
shutter depending if the film projector lockout mode has been set to lock out or power control mode. See the command
FPOL for more details.

1.6 Enhanced Color Correction (P7)

Commands have been included to utilize Texas Instruments’ Enhanced Color Correction Algorithm. When viewing
REC709 images use Entertainment Experiences' film look target color gamut by selecting index 5. When viewing
Tristimulus images use Entertainment Experiences' XYZ target color gamut by selecting index 6. See the ECC command
for more details.

Page 4 of 33

BOXLIGHT PRO80S3 Projector Preliminary User’s Manual

1.7 Ambient Light Compensation

Commands have been included to utilize Texas Instruments’ Dgamma table selection. There are three Entertainment
Experience dgamma tables provided to compensate for low, medium and high ambient room light levels. For low light
levels use dgamma table 5. For medium light levels use dgamma table 9/10. For high light levels user dgamma table 14.
See the command GAMMA for more details.

1.8 Lamp Module Replacement

High pressure lamp may explode if improperly handled. Refer servicing to qualified service personnel. The customer
should never attempt to disassemble the lamp or to dispose of the lamp casing other than by returning to the dealer. If the
lamp breaks, leave the area immediately and stay away for at least 30 minutes and ventilate the room so as not to inhale
the mercury vapor. If you inhale the mercury vapor, see a physician immediately and follow their instructions. Lamp
replacement is recommended after 3000 hours of use. Wait 60 minutes after turning off and unplugging the projector
power cord before performing the lamp replacement.

1.9 Filter Replacement

If the air filter is clogged with dust it can cause the projector to overheat , cause component failure or even catch on fire.
The filter should be replaced when clogged or when 10,000 hours of use has occurred. Contact the dealer to order a new
filter, never reuse an old filter. To replace the filter follow the steps that are provided in the following pages.

STEP 1: Remove the 2 screws.

Flow Control – Re-enable xmtr/rcvr
Flow Control – Disable xmtr/rcvr
Not placed in queue. Terminates current operations, flush queue

A number of control characters are set up as

hot keys

to perform the function of the Mode, Pattern, etc. buttons on the
PCB and on the rear panel switch via the serial interface. No <CR> terminator is required for these commands to execute.
See the first entry in Section 3.2 of the commands descriptions.

2.1 The ! Hot Key

Typing or sending a single exclamation point (!) immediately after the prompt with no whitespace or control characters –
will repeat the last command (the exclamation point is not echoed). If ANY characters are sent between the prompt and
the “!” – even a <CR> - the previous command will be lost and cannot be repeated using the “!” option. “!” just re-processes
the current contents of the command buffer so it will also repeat illegal commands or commands with illegal or missing
parameters.

2.2 ASCII Control Characters

In almost all cases sending an <ESC> character will terminate current operations and return a command prompt. It can
also be used when sending commands manually through a terminal to cancel any characters typed in after the prompt.

Whitespace characters - <TAB> and <SPACE> - are treated identically. Line feeds - <LF> - are queued but are otherwise
ignored by the code. A “newline” is always a <CR><LF> pair. The prompt is a newline followed by a > and a space.

Single <BKSP> characters are echoed and back up the queue pointer. A <BKSP> sent to the projector is not converted to
a “destructive” backspace string - <BKSP><SPACE><BKSP> when echoed. Only a single ASCII <BKSP> will be echoed.
If the terminal program can be configured to send <BKSP><SPACE><BKSP> when the Backspace Key is pressed, this
option should be selected.

Commands sent to the board in either mode can be terminated with either a single <CR> or a <CR><LF> pair. The <LF>
character triggers command parsing and execution. The <LF> is ignored. Neither commands nor hex data is case­sensitive.

2.3 ZOOM, FOCUS and Lens Shift Commands

ZOOM, FOCUS and Lens Shift Serial Commands
The following commands turn on the specified motors. The motors will stay energized until an <ESC> character is sent to
the projector. The last character of each command is an ASCII digit from 0 to 3 with no intervening whitespace. This
determines motor speed with 0 being the slowest and 3 the fastest. All of the motors have clutches or limit switches to
prevent damage if they are allowed to run after reaching a mechanical limit.

3.1 Lens Shift, ZOOM and FOCUS Commands

The following commands turn on the specified motors. The motor will stay energized until an <ESC> character is sent to
the projector. The last character of each command is an ASCII digit form 0 to 3 with no intervening whitespace. This
determines motor speed with 0 being the slowest and 3 the fastest.

If an N prefix is appended to the command mnemonic the command is a NUDGE. NUDGE commands turn on the
specified motors at full speed for a timed period. An <ESC> character is not needed to terminate the command. The
purpose is to generate small changes in image position, focus or size. The last numeric character of the command
determines period the motor is energized with 0 being the shortest and 3 the longest. Due to backlash in the motor/drive
assemblies, a single NUDGE – especially a 0 or 1 – may not generate any noticeable change.

All of the motors have clutches or limit switches to prevent damage if they are allowed to run after reaching a mechanical
limit.

DGAMMA Download to De-gamma Mailbox DGAMMA

Download de-gamma tables to the formatter’s degamma mailbox. DGAMMA takes three parameters. The first is a single
letter (r, g, b or a) specifying which formatter (or all of them) gets the table. The second is also a single letter (b or w)
specifying whether the table is formatted as bytes or words (16 bits). The last is a decimal parameter which specifies the
number of entries (1/2 the total number of bytes). Valid values for this parameter are 256, 512, 1024, or 2048. After the
command is issued, the user will be prompted to send the table as a series of hexadecimal bytes or words. Each entry is
16 bits. If byte mode is selected, send the LSB first. The table can be formatted rather loosely. Any ASCII character less
than ‘0’ (3016) is treated as a terminator. Any number of terminators may be inserted between values so the table can be
a single column of values separated by “newlines” or a column of comma separated values or even a string of hex digits
without any terminations as long as leading zeros are included with each byte or word.

If all formatters are to be loaded, a prompt will be issued after each successful download and a total of three separate
tables will have to be sent.

Enable (V+) or disable (V-) VERBOSE mode on the serial interface. When VERBOSE is enabled all messages –
informational, error and status, etc. – are sent as human readable text. When disabled those messages are sent as a 6
character ASCII group. There are two types of messages: critical and non-critical. Non-critical messages can be enabled
or disabled using the M+ and M- commands. The first character of non-critical messages is a percent sign (%). Critical
messages are headed by an exclamation point (!). The next two characters form a unique 8-bit hexadecimal code
identifying the message (see below). The last three characters are a dollar sign ($) followed by a <CR> and <LF>.

DGAMMA and most of the DEBUG/Maintenance commands output verbose messages regardless of whether VERBOSE
is enabled or disabled.

MDNLD Download Measured Color Gamut Data MDNLD

Download Measured Color data for storage on the BLUE Formatter’s EEPROM. When the command is entered, the
operator is prompted to send 16 bytes of data: the X and Y CIE coordinates of the un-enhanced GREEN, RED, BLUE and
WHITE colors. Each coordinate is 16 bits - 2 bytes - sent least significant byte first in hexadecimal. For each coordinate,
first multiply by 65536 and convert to hexadecimal. Output two hexadecimal bytes, LS byte first, for each of the 8
coordinates in order: Gx, Gy, Rx, Ry, Bx, By, Wx, Wy , Bx By ,WY and BY. The values can be manually typed from the
terminal or stored in a file and sent to the controller board using the terminal’s “Send Text File” utility. Characters typed of
sent will NOT be echoed. The 16 bytes sent may be <SPACE>, <TAB>, <CR> or <LF> separated.

After the data is downloaded, the coordinates will be displayed in decimal format for confirmation.

OCMD Ballast Communications OCMD

This command is used for sending commands to the Osram Lamp ballast. The first parameter determines which of the two
ballast ports is addressed. The second is the ballast register address (hexadecimal – e.g., STATUS = 22

). See the
Osram documentation for register details. If the command requires data to sent those bytes are appended to the
command (hexadecimal and space delimited). If the command causes the ballast to return data – no just echo the
command – the response will be output in hexadecimal bytes. The ballast status command is special in that the status bits
are decoded (see below). Examples:

Syntax: ocmd { 1 | 2 } {ballast command} [data

> ocmd 2 22
Command response = E0

4.1 Pan, Zoom and Focus Speed and Nudge Functions

The Pan, Zoom and Focus buttons can be used to manually control the projected image. All of the motors may be driven
at one of four speeds to make small incremental adjustments. In addition a nudge function is implemented. When any of
the control keys are pressed and released, the associated motors will be turned on for a short period of time, causing a
small incremental change in the image. In the following descriptions this nomenclature is used:

P = a quick button press and release – press and release time each less that about 0.25 seconds
H = the button is held down
PP = two quick button presses and releases – down times and intervening up times each less that about 0.25

seconds, etc.

..PH = One or more quick button presses and releases followed by a hold

The nudge function generates small changes in lens position,etc., by applying power to the associated motor for one of
four time intervals: 12.5, 25, 50 or 100 milliseconds. Nudges are generated by a number of quick button depressions and
releases. Nudge increments are controlled by the number of quick button presses – up to four. More than four are treated
the same as four.

P – smallest change – 12.5 msec
PP – 25 msec
PPP – 50 msec
PPPP – largest change – 100 msec
PP..PP – largest change – 100 msec

Page 32 of 33

BOXLIGHT PRO80S3 Projector Preliminary User’s Manual

Continuous changes are generated by a number of quick presses followed by a hold. Motor speeds are determined by the
number of quick button presses – up to three – before holding the button down.

H – very slow
PH – slow
PPH – medium
PPPH – fast
PP..PH – fast

Release the button to stop the motor. Note that there is about a 0.25 to 0.35 second delay between button release and
motor off.
