Manual Revision 1.2 11 microLite Transmitter User Manual 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 Revision 1.2 12 microLite Transmitter User Manual Revision 1.2 13 microLite Transmitter User Manual 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 Multiple Output Frequencies Microwave output frequencies in multiple bands. User orderable frequency band options. User programmable channels and offsets within band. Compatible with advanced video cameras. Compatible with industry standard SD video cameras. Direct audio input option for use with video signals that do not contain embedded audio. Direct SDI input for cameras with embedded audio. Industry standard compliant video compression. Implements latest algorithms for high quality. Data is transmitted along with audio and video to the receiver. Convenient menu and button based graphical user interface for Windows PC’s. Used to program the preset settings on the top panel. Fits in small form factor applications. ASI, HD-SDI, and SD-SDI Inputs NTSC or PAL Composite Video Inputs Stereo Audio Line Inputs Embedded Audios MPEG4 (H.264 Part 10) Encoder User Data Channel Remote Control GUI for Programming the MicroLite Compact Housing Table 2-1: Summary of High Level Features and Benefits Revision 1.2 14 microLite Transmitter User Manual 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 Revision 1.2 15 microLite Transmitter User Manual 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. Revision 1.2 16 microLite Transmitter User Manual 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 RS232 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 (M27-000100A) 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. Contact IMT Tech Support for additional details. 2.2 MicroLite Physical Features and Interfaces Figure 2-2: microLite Transmitter User Interface Figure 2-3: MLT Connectors Revision 1.2 17 microLite Transmitter User Manual Table 2-2: microLite Connectors Connector (from left above) Label on Unit Description Lemo 7 pin Power & Control Power, USB, RS-232 Remote Control Interface Telocate Audio Left Audio Line Input Telocate Audio Right Audio Line Input Lemo 5 pin Ext ASI input, ASI Output, User Data, and USB BNC Video & SDI Composite NTSC or PAL Input, HD-SDI, SD-SDI Input ______________________________________________________________ !
