This document is a setup guide for the SHARP PG-MB60X Multimedia Projector, providing essential information for installation, connectivity, and control.
Function Description
The SHARP PG-MB60X is a multimedia projector designed to display images from various sources onto a screen. It supports both NORMAL (4:3) and STRETCH (16:9) aspect ratios, making it versatile for different content types, from standard presentations to widescreen video. The projector can be controlled remotely via an RS-232C serial connection, allowing for integration into automated systems or control from a computer. It also features a USB terminal for potential connectivity with other devices, though specific USB functions are not detailed in this guide.
Important Technical Specifications
Projection and Screen Size:
The projector's screen size and projection distance are critical for proper installation. The guide provides detailed tables for both NORMAL (4:3) and STRETCH (16:9) modes, listing diagonal screen size, width, height, minimum and maximum projection distances (L1 and L2), and the distance from the bottom of the image to the lens center (H).
For NORMAL Mode (4:3):
- Diagonal Screen Size (X): Ranges from 40" (102 cm) to 300" (762 cm).
- Width: Ranges from 81 cm (32") to 610 cm (240").
- Height: Ranges from 61 cm (24") to 457 cm (180").
- Minimum Projection Distance (L1): From 1.2 m (4' 0") for a 40" screen to 9.1 m (29' 9") for a 300" screen.
- Maximum Projection Distance (L2): From 1.8 m (6' 0") for a 40" screen to 13.7 m (44' 9") for a 300" screen.
- Distance from bottom of image to lens center (H): Ranges from -1.4 cm (-17/32") to -10.2 cm (-4 1/64").
- Formulas: L1 (m) = 0.0302X, L2 (m) = 0.0455X, H (cm) = -0.034X.
For STRETCH Mode (16:9):
- Diagonal Screen Size (X): Ranges from 40" (102 cm) to 250" (635 cm).
- Width: Ranges from 89 cm (35") to 553 cm (218").
- Height: Ranges from 50 cm (20") to 311 cm (123").
- Minimum Projection Distance (L1): From 1.3 m (4' 4") for a 40" screen to 8.2 m (27' 0") for a 250" screen.
- Maximum Projection Distance (L2): From 2.0 m (6' 6") for a 40" screen to 12.4 m (40' 8") for a 250" screen.
- Distance from bottom of image to lens center (H): Ranges from -9.8 cm (-3 55/64") to -61.1 cm (-24 5/64").
- Formulas: L1 (m) = 0.0329X, L2 (m) = 0.04957X, H (cm) = -0.24459X.
- Note: Values with a minus (-) sign for H indicate that the lens center is lower than the bottom of the image. An error of ±3% in these values is possible.
Connectivity:
The projector offers multiple input and control options:
- INPUT 1/INPUT 2 and OUTPUT RGB Signal Terminal: 15-pin Mini D-sub female connector.
- RGB Input: Supports Video input (red, green/sync on green, blue), Earth connections, GND, Bi-directional data, Horizontal sync (TTL level), Vertical sync (TTL level), and Data clock.
- Component Input: Supports PR (CR), Y, PB (CB), and corresponding Earth connections.
- RS-232C Terminal: 9-pin Mini DIN female connector for serial control.
- Pin Assignments: Includes Receive Data (RD), Send Data (SD), Signal Ground (SG), RS, and CS.
- DIN-D-sub RS-232C adaptor: A 9-pin D-sub male connector is used for adaptation, with identical pin assignments for RD, SD, SG, RS, and CS. Pins 8 (CS) and 7 (RS) are internally short-circuited within the projector.
- RS-232C Cable Recommended Connection: A 9-pin D-sub female connector is recommended, with direct connections for CD, RD, SD, ER, SG, DR, RS, CS, and CI. Depending on the controlling device, connecting Pin 4 and Pin 6 on the controlling device may be necessary.
- USB Terminal: 4-pin B-type USB female connector.
- Pin Assignments: VCC (USB power), USB- (USB data-), USB+ (USB data+), and SG (GND).
RS-232C Communication Conditions:
- Signal format: Conforms to RS-232C standard.
- Baud rate: 9,600 bps / 115,200 bps (user-settable to match the computer).
- Data length: 8 bits.
- Parity bit: None.
- Stop bit: 1 bit.
- Flow control: None.
- Command format: C1 C2 C3 C4 P1 P2 P3 P4 (Command 4-digit, Parameter 4-digit, followed by Return code (0DH)).
- Response code format:
- Normal response: O K (followed by Return code (0DH)).
- Problem response: E R R (followed by Return code (0DH)).
Usage Features
- Flexible Installation: The detailed projection tables allow for precise installation planning to achieve optimal screen size and image quality for various room configurations.
- Remote Control: The RS-232C interface enables comprehensive remote control of the projector from a computer, facilitating integration into professional AV setups or smart home systems. Commands cover power on/off, input selection, picture mode, brightness, volume, keystone correction, OSD display, video system, background, Eco mode, auto power off, auto keystone, speaker control, audio output, projector mode (reverse/invert), and language settings.
- Picture Modes: Supports various picture modes including Standard, Presentation, Cinema, and Game for both RGB and Video inputs, allowing optimization for different content.
- Image Adjustment: Features include resize options (Normal, Dot By Dot, Border, Stretch), bright boost, color temperature (CLR Temp), sRGB mode, signal type selection (Auto, RGB, Component), and adjustment reset.
- System Information: Commands can retrieve lamp usage time and remaining lamp life percentage.
- Auto Sync: The projector supports auto synchronization for both off and on states.
Maintenance Features
- Lamp Status Monitoring: The RS-232C commands allow for monitoring of the lamp status, including normal operation, high temperature, fan errors, low lamp life (5% or less), burnt-out lamp, ignition failure, and abnormally high temperature. This is crucial for proactive maintenance and timely lamp replacement.
- Auto Power Off: The projector can be configured to automatically power off, which can help conserve lamp life and energy.
- Reset Functions: Commands are available to reset various adjustments (Input 1-4 Adjustment Reset) and perform an "All Reset" to restore default settings.
- Cooling Period: When putting the projector into standby mode, it is important to wait at least 90 seconds for the cooling fan to stop before sending further commands, ensuring proper cooling and extending component lifespan.
- Warm-up Period: After turning on the power, a waiting period of at least 30 seconds is recommended before transmitting commands, allowing the projector to stabilize.
- Command Sequencing: When sending multiple commands, it is advised to wait for the projector's reply before sending the next command to prevent communication errors.
- Non-disappearing OSD: Certain commands (POWR????, TABN___1, TLPS___1, TLTT___1, TLTL___1) will not clear the on-screen display or reset the "Auto Power Off" timer when no signal is present, which can be useful for diagnostics without interrupting the display.
