BOXLIGHT PRO80S3 Projector Preliminary User’s Manual
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.

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.
