microLite Transmitter User Manual Revision 1.2 11
microLite Transmitter User Manual Revision 1.2 12 1 Introduction This document is a user manual for RF CENTRAL’s microLite microwave video transmitter. The microLite is a compact transmitter that digitally encodes video signals and transmits them using COFDM modulation over microwave frequencies. The unit accepts HD-SDI, SD-SDI, or composite video inputs in NTSC or PAL format, and can also accept User Data (e.g. NMEA GPS sentences) for transmission along with the main input signals. It has a built in MPEG4 (H.264 part 10 AVC) encoder and COFDM modulator. The microLite is housed in an ultra compact, lightweight enclosure. Throughout this manual, the product is referred to as the “microLite”, the “microLite Transmitter”, “MLT”, “microLite TX”, or simply the “transmitter.” 1.1 Manual Overview The contents of this manual are as follows: Chapter 2 – Describes the theory of operation and the features of microLite Transmitter. Chapter 3 – Contains a list of the microLite Transmitter specifications. The specifications include transmitter feature specifications, power requirements, environmental specifications, and I/O specifications. Chapter 4 – Describes operating and installation procedures for the microLite Transmitter. Appendix A – Explains the different default preset configurations

microLite Transmitter User Manual Revision 1.2 14 2 microLite Description This chapter describes the microLite transmitter theory of operation, features, and physical description. It also contains a block diagram of the MLT circuitry and a typical application example. The MLT has external connectors and features direct plug-in compatibility with off the shelf equipment using industry standard interfaces. The MLT internal circuitry encodes the audio and video signals, and organizes the compressed data into digital video transport streams. The transmitter uses COFDM modulation and transmits at microwave frequencies in the specific band supported by the unit. Though the unit ships pre-configured, a graphical user interface that runs on a Windows PC is available to modify the operating parameters. IMT has the ability, should the need ever arise, to provide the user with firmware files and instructions for local firmware installation, such as for feature upgrades, etc. Feature Benefit COFDM Microwave Digital Video Transmitter Microwave output frequencies in multiple bands. Multiple Output Frequencies User orderable frequency band options. User programmable channels and offsets within band. ASI, HD-SDI, and SD-SDI Inputs Compatible with advanced video cameras. NTSC or PAL Composite Video Inputs Compatible with industry standard SD video cameras. Stereo Audio Line Inputs Direct audio input option for use with video signals that do not contain embedded audio. Embedded Audios Direct SDI input for cameras with embedded audio. MPEG4 (H.264 Part 10) Encoder Industry standard compliant video compression. Implements latest algorithms for high quality. User Data Channel Data is transmitted along with audio and video to the receiver. Remote Control GUI for Programming the MicroLite Convenient menu and button based graphical user interface for Windows PC’s. Used to program the preset settings on the top panel.

microLite Transmitter User Manual Revision 1.2 15 2.1 Theory of Operation 2.1.1 Functional Block Diagram Major blocks in the MICROLITE TX include: • Video Input Interfaces - ASI or HD-SDI, SD-SDI; NTSC or PAL • Stereo Audio Input Interface • MPEG4 Video Compression Circuit • COFDM Modulator • Microwave Transmitter and Antenna Connector • Programmers Serial Interface for Remote Control Purposes • Internal Microprocessor and Memory • Power Circuitry Figure 2-1: Internal Block Diagram
microLite Transmitter User Manual Revision 1.2 16 2.1.2 Power, Remote Control, and User Data Interface Connector The microLite Transmitter Power, Remote Control, and User Data interface includes power and ground connections plus two RS-232 serial port interfaces. 2.1.3 Audio and Video Input Connectors The microLite TX has two analog audio inputs and one video input. They are used for stereo audio and HD/SD-SDI or NTSC/PAL video input. Refer to Chapter 3 for specifications of these signals. 2.1.4 User Data Input A data channel may be transmitted along with the audio and video information. The data channel is accessed through a RS-232 serial interface in the EXT connector. 2.1.5 MPEG4 Encoder (H.264 Part 10) The MLT encodes the input video signal before modulation and transmission to reduce bandwidth. The microLite TX contains a built-in MPEG4 (H.264 part 10) encoder for this purpose. The microLite TX features the latest compression methods utilizing I, P and B frames for more accurate encoding of compressed video signals. 2.1.6 COFDM Modulator The COFDM modulator receives data from the output of the MPEG4 AVC encoder through a circuit that enhances the security of transmissions. The microLite TX is able to transmit data at high data rates and with low error rates using COFDM modulation techniques. The data rate used by the transmitter depends upon the CODFM modulator settings used. 2.1.7 RF Transmitter The microLite microwave circuits mix the signal to the desired microwave frequency. The signal is filtered and boosted through a low noise output amplifier. The microLite TX has a single SMA style antenna connector. The output impedance of the antenna connector is 50 ohms. Note: On 2.4 and 5.8GHz models that operate in USA, the connectors are RP-SMA due to FCC requirements. Refer to Chapter 3, “Specifications” for frequency band and channel tuning specifications.
microLite Transmitter User Manual Revision 1.2 17 2.1.8 Remote Control and Firmware 2.1.8.1 Remote Control via Serial Interface An RS-232 command set is implemented to allow remote control of all configuration options, as well as monitoring of internal status and settings. Commands and responses are sent via the RS-232 serial interface located on the Power/Control connector. The IMT NanoController GUI is available for controlling the unit via the RS-232 serial interface. A Windows compatible computer running Windows XP or Vista with 500 MB of memory and 1 GHz Pentium or above can is needed. Refer to Chapter 4, “Operation” and the NanoController Manual (M27-0001-00A) for more information. 2.1.8.2 Firmware updates The unit firmware is updated via the USB interface on the Power/Control connector, using the IMT NanoTx Programmer software. A programming cable (IMT part number 922-B963-01A-R) is required.

microLite Transmitter User Manual Revision 1.2 30 4 Operation While this chapter contains basic information about the operation of the microLite transmitter, the programming of the unit (including preset configuration) via the NanoController GUI is not covered. Please refer to the IMT NanoController manual (IMT Publication: M27-0001-00A) for detailed information on how to program and configure the unit. In this chapter, you will find info on how to use the microLite transmitter to transmit video, audio, and user data. 4.1 microLite Set-up • Remove microLite Transmitter (MLT) from the case. Mounting bracket and Litepanels kit is preassembled. Attach assembly to camera. • Connect video source to the Video/SDI Input (BNC jack) using a 75Ω BNC cable. • Connect analog audio source (Telocate to XLR) to the transmitter using the two provided audio cables (if not using embedded audio). • Connect TX antenna (small omni directional) to the RF output (SMA). • Connect the power source to the MLT using the supplied transmitter power cable. • Select the desired preset using the set button. • Transmit signal using the MLT Tx/Standby button. • Hi/Low button will control the power output level. • microLite Transmitter will have one of the following button controls: o BARS – Will turn internal Bars on and off. o FAN – Will turn the internal fan on and off Note: The unit has an internal fan and the air ducts must not be blocked. Figure 4-1: Detail of Air Ducts
microLite Transmitter User Manual Revision 1.2 31 4.2 Powering Up the microLite Turn on the power to the overall system. The microLite requires up to 25 seconds to complete its internal power up sequence. The top row of front panel preset led’s (1, 2, 3, 4) light up in succession as the unit advances thru the boot process. Supply current will jump up in steps as internal circuits are powered. The final DC supply current will settle after 20 seconds. Note: Before applying power, ensure proper antenna termination on RF output. 4.3 microLite Pre-Configured Options The microLite has a wide range of programmable settings. It is shipped with factory default settings that are applicable to many use cases. Before using the microLite in your application, you should pre-configure it to for the settings you want to use in your application.
