13281-1-010 1. OVERVIEW 1.1 TECHNOLOGY The HD MINI TX is a miniature HD/SD video and audio microwave transmitter. It has been designed for simple, secure and reliable operation in the field. The latest technology is utilized to provide the perfect combination of high performance, ease of use, small size and low power operation. 1.1.1 Multi-Format Video and Audio Inputs The transmitter accepts video in either SMPTE-170M, SD-SDI or HD-SDI and ASI format through a single front panel connector.
13281-1-010 1.1.5 Low Latency A unique technique is used to provide ultra low latency of 2 video frames when operating with the BSI receiver. In compatibility mode the HD MINI TX can be used with any HD H.264 receiver and can achieve a latency of 4 video frames. Full technical specifications are available in section 5.1. 1.
13281-1-010 1.3 LOCATION AND FUNCTIONS OF PARTS 1.3.1 CONNECTORS 1 – Power (PWR) A single connector accepts 2 channels of balanced analog audio at Microphone or Line level. Break-out cables are provided for Telocate (Mic) and RCA (Line) connectors. 2 – Audio Connector (A1) A single connector accepts 2 channels of balanced analog audio at Microphone or Line level. Audio gain level is set from the remote control software.
13281-1-010 CONTROLS AND INDICATORS 7 – Power/Data Indicator A red LED indicator that is on (with infrequent flashes off) when in an active powered state, and is off (with infrequent flashes on) when in standby mode. 8 – Built-in Test Indicator A green LED indicator that is solid when BIT passes, and flashes when BIT fails. 9 – Preset Selector Switch Rotary switch used to select 1 of 16 preset configurations for the Transmitter. Presets can be configured using a PC connected to the Control connector (5).
13281-1-010 2. INSTALLATION 2.1 Typical System A typical minimum operational system would include the HD MINI TX, camera, microphone, battery and microwave antenna. 2.2 Connecting a Video Source The HD MINI TX accepts video in NTSC, SDI and HD-SDI formats. The video source can be any device which outputs video in one of these formats, for example a video camera or VTR.
13281-1-010 2.3 Connecting an ASI Source The HD MINI TX can accept an MPEG-2 Transport Stream (TS) in ASI format. Care must be taken to ensure the TS bit-rate is low enough to pass through the modulated RF link. To connect the ASI source: 1. Determine if your ASI source is in the supported format. 2. Connect a video cable from your ASI source to the VIDEO/ANCILLARY DATA connector on the HD MINI TX. 3. The ASI signal is automatically detected. 2.
281-1-010 2.6 Connecting Control/Programming To connect Remote Control / Programming Data: 1. Connect the DB-9 connector side of the ADR cable to the serial port on your Remote Control / Programming PC 2. Plug the Lemo connector side of the ADR cable to the ADR connector on the HD Mini TX 2.7 Connecting an Antenna The antenna should be connected to the HD MINI TX with the shortest possible cable in order to minimize losses. If possible, connect the antenna directly to the HD MINI TX.
13281-1-010 3. OPERATING INSTRUCTIONS 3.1 Turning on the Power The HD MINI TX does not include a power switch. To turn on the unit simply connect power to the POWER connector. CAUTION HD MINI TX will start transmitting as soon as power is applied 3.2 Checking Status 3.2.1 Checking for Power Status The Data LED is used to display the power status. The indicator state is decoded as follows: LED STATE On, Flashing Off Off, Flashing On MEANING Power Standby 3.2.
13281-1-010 3.2.3 Detailed Status Information Detailed status information for the HD MINI TX can be displayed in the Remote Control / Programming GUI. Status information available includes: battery voltage, case temperature, video lock, audio level, synthesizer lock, RF output frequency, modulation scheme, video and audio encoder settings, audio gain, encryption active, DAC lock. 3.3 Local Control 3.3.
13281-1-010 3.4 Using the GUI 3.4.1 Connecting 1. Connect the laptop or PC to the HD MINI TX using the Control/Programming cable provided. See section 2.6 for details. 2. Connect an antenna, video and audio sources as required.
13281-1-010 3.4.2 GUI Overview The key features of the Remote Control / Programming software are shown below: 1 – Main Menu Used to load and save settings, select the Com port and display help information. 2 – Frequency Selection Allows selection of the RF carrier frequency in 250 kHz steps (if using the increment/decrement buttons). “Low RF Power” button allows the user to drop output power from 200 mW to 20 mW. 3 – Modulation Selection Dop-down box selections determine modulation scheme and parameters.
13281-1-010 Displays BIT results of the connected HD MINI TX. Note: “Synth”, “DAC”, and “Deserializer” will not pass BIT if the unit is in standby mode. 6 – GOP Length Selection and Low Latency Mode Used to set GOP length as required and toggle low latency mode. 7 – Audio Gain Selection Used to set audio gain for both of the audio inputs. 8 – Power Mode Allows user to toggle between Standby and Awake modes. 3.4.
13281-1-010 3.5 Remote Control Mode Remote Control Mode is used for real time control of the HD MINI TX. Any setting changes made in the main window of the GUI are executed immediately by the HD MINI TX. When the Control/Programming cable is removed from the HD MINI TX, the unit reverts to Local Control. 3.6 A Note about Low Latency Mode Low latency mode provides a very small end-to-end delay for the transmission of video and audio.
13281-1-010 3.7.1 Program Channels Controls 1 – Channel Parameter Fields Used to establish carrier frequency, modulation scheme, and other parameters for the 16 channel presets. 2 – Audio Gain Selection Sets the gain for each audio input. Gain settings apply to all channel presets. 3 – Verify Button Verifies the channel preset information displayed on the GUI against the settings saved to the HD MINI TX.
13281-1-010 8 –Load Defaults Button Use this button to load a standard configuration for all controls. 3.7.2 Configuring the Presets The 16 presets are configured by changing the settings in the text fields, check boxes, and drop down menus of the Program Channels window. 1. For each switch position 1 through F, select frequency, modulation, code rate, guard interval, GOP length, and low latency. 2. Set the desired Audio Gain at the bottom center of the window. 3.
