microLite Transmitter User Manual IC Notice: IC Avis 1. Under Industry Canada regulations, this radio transmitter may only operate using an antenna of a type and maximum (or lesser) gain approved for the transmitter by Industry Canada. To reduce potential radio interference to other users, the antenna type and its gain should be so chosen that the equivalent isotropically radiated power (e.i.r.p.) is not more than that necessary for successful communication.

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.

microLite Transmitter User Manual 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.
microLite Transmitter User Manual 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.
microLite Transmitter User Manual Figure 4-3: Unit Interface - Sports and Entertainment 4.4.1 Unit Interface Buttons 4.4.1.1 SET The Set button Advances the unit through the presets. The 1-12 LED’s indicate in GREEN, which preset is currently active. 4.4.1.2 TX/STBY The TX/STBY button toggles between Transmit and Standby modes. TX LED= Green for TX mode. Yellow LED for standby mode. 4.4.1.3 Hi /LOW The HI/LOW button toggles between High and Low Power modes.
microLite Transmitter User Manual 4.4.2.4 Video The Video LED will display Green when Video is present on SDI input connector. Blinking YELLOW indicates that no video input signal (composite or SDI) is detected. This only detects the presence of video and does NOT detect if the encoder supports the format applied. See Section 3.3 for supported formats 4.
