2 MICROLITE Description
This chapter describes the MLR features and theory of operation. It also includes a block diagram of the MLR and a description of the internal circuits.
2.1 microLite Features and Benefits
Table 2-1 summarizes key features and benefits of the MLR.
The microLite Receiver is a receiver that utilizes advanced silicon tuners and dual antenna inputs for robust, error free signal reception. The MLR can receive either HD or SD video transmissions using COFDM modulated microwave signals. The MLR uses maximal-ratio combining to take advantage of its dual antennas.
The silicon tuners employed in the microLite Receiver includes low noise amplification, automated gain control, mixing, tuning, and demodulation functions on one integrated circuit. This facilitates low power, high performance, and space savings.
The microLite Receiver contains a built-in, industry compliant, MPEG4 (H.264 part 10) decoder. The MLR can output ASI, HD-SDI, SD-SDI, or Composite video, as well as User Data. Stereo audio is included on the ASI and SDI outputs, and the MLR has left and right audio output jacks.
The MLR features a 100 Mbps Ethernet LAN interface for streaming video over IP. This feature uses UDP/IP and allows received video to be viewed remotely using MPEG4 decoder software on a personal computer. A compatible MPEG4 decoder that runs on your remote host PC is required for this application.
The top panel of the microLite Receiver has signal strength, status, and monitoring LEDs that provide useful information at a glance. The user interface also features a selector button for choosing between 16 pre-programmed configurations called “Presets”.
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.

5 Operation
While this chapter contains basic information about the operation of the microLite Receiver, the programming of the unit (including preset configuration) via the NanoController GUI is not covered. Please refer to the NanoController manual (IMT Publication: M27-0001-00A) for detailed information on how to program and configure the unit.
In this section, you will find information on how to use the MLR to receive video, audio, and user data, and how to stream video to a PC or network.
5.1 Power up the MicroLite Receiver
Turn on the power to the overall system.
The MLR requires up to 20 seconds to complete the power up sequence. Supply current will jump up in steps as internal circuits are powered. The final DC supply current will settle after 20 seconds.
The MLR contains flash memory, which retains all stored preset configuration settings when the unit is not powered.
5.2 Pre-Configure the MLR user options
The MLR has a wide range of programmable settings. Before using the MLR in your application, you should pre-configure it to for the settings you want to use in your application. Settings are selected and configured using the NanoController software, or a third party alternative. Please refer to the NanoController documentation for details, or contact IMT Technical Support.
5.3 Control and LED Interface
Figure 5-1: Front Panel Controls and Indicators
The MLR has several Buttons and LED’s on the front panel, to perform basic operation and view unit status. Any changes made via a remote control interface will be reflected by the front panel LED’s.
Revision 1.1 25
The MLR can be pre-configured using the programmable serial interface and then quickly changed between preset modes using the “Set” pushbutton.
5.3.1 Buttons:
Set Button - Advances the unit through the presets. The 1-12 LED’s indicate in
GREEN, which preset is currently active.
SCAN(future Feature) - Scan available presets until it locks on an incoming signal.
5.3.2 Status Indicators:
Alarm - Normally OFF. If an Alarm is present, the LED will be RED. Rx Lock - When YELLOW, the demodulator is locked. Streaming - Indicates that the unit is streaming video through the Ethernet port. Decoder – Decoder Operating RSSI - LED’s will light to provide a Received Signal Strength Indicator.
5.4 Using the MLR to Receive Audio and Video
The MLR receives and demodulates COFDM radio signals from the microLite Transmitter. It then decodes the MPEG4 transport stream for output.
The dual antenna diversity feature of the MLR is used to maximize the robustness of video reception. The primary goal of dual antenna diversity is to enable the user to prevent line of site obstruction on the transmission path from causing receiver errors to occur. By separating the antennas, the user has two chances to receive the signal properly, regardless of obstructions between the transmitter and MLR antennas. Properly directing your antenna to the transmit source is key obtaining the best range possible.
Video may be viewed on a monitor, which accepts SD Composite video, or SDI. MPEG4 encoded video is also included in the transport stream on the ASI output, and must be decoded using an MPEG4 decoder prior to viewing on a monitor.
Audio can be output to a recorder or amplifier. Audio is also embedded in SDI outputs, and included in the transport stream on the ASI output.
Streaming video and audio can be output via a laptop or PC with a compatible MPEG4 decoder program.
5.5 Verify Operation
After installing the MLR, turn on the power to the receiver and your overall system. The LED’s on presets 1-4 will sequentially illuminate until boot up is complete.
Verify operation of the MLR by using the following methods:
Revision 1.1 26

In addition to the instructions above, when shipping internationally we recommend the use of a courier such as Federal Express, UPS, etc, and that the goods be shipped DOOR-TO-DOOR PRE-PAID. This will reduce Customs costs, handling charges and delays. Enclose all the information above, plus a statement that the equipment was manufactured in the United States (the latter is needed to expedite customs processing).
