13418-1-001 1. OVERVIEW 1.1 TECHNOLOGY The HD IN-CAR TX is an 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 NTSC, SD-SDI, HD-SDI, format through four front panel connectors.
13418-1-001 adjacent channels (i.e. one 16 MHz wide output). Non-adjacent channel operation is not possible. 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 IN-CAR 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.
13418-1-001 1.3 LOCATION AND FUNCTIONS OF PARTS 1.3.1 CONNECTORS 1 V1 V2 A1 V3 A2 V4 A3 A4 2 3 DATA PWR UHF RF 4 STAT LCK 5 6 1 – Video Inputs (V1-V4) 7-pin Lemo connectors. The Transmitter auto detects the video format (NTSC, SDI, HDSDI), resolution and frame rate. Data to/from the camera can also be found on this connector. 2 – Aux Data Interface (DATA) 6-pin Lemo connector. Provides communications for programming and remote control, as well as a monitor output.
13418-1-001 5 – Audio Inputs (A1-A4) 3-pin Lemo connectors. Each connector accepts 1 channel of balanced analog audio at Microphone or Line level. Audio gain level is set from the remote control software. 6 – Control Connector (UHF) 5-pin Lemo connector. Provides power and an RS-485 link to the data receiver. Also allows transmitter control via PC using the Digital Camera Controller software. 1.3.

INSTALLATION 2.1 Typical System A typical minimum operational system would include the HD IN-CAR TX, camera, microphone, battery and microwave antenna. TO REMOTE CONTROL HARDWARE 2.2 Connecting a Video Source The HD IN-CAR TX accepts video in NTSC, SDI and HD-SDI formats.
13418-1-001 3. The video format is automatically detected. 2.3 Connecting Audio The HD IN-CAR TX accepts 4 channels of balanced analog audio at microphone (Mic) level. To connect an audio source: 1. Connect an audio cable from your mic source to an audio input (A1 – A4). Make sure that associated video input is connected as well. 2. The audio gain level can be adjusted from the remote control software. 2.
13418-1-001 2.6 Connecting an Antenna The antenna should be connected to the HD IN-CAR TX with the shortest possible cable in order to minimize losses. If possible, connect the antenna directly to the HD IN-CAR TX. To connect the antenna: 1. Connect the antenna to your RF cable 2. Connect the RF cable to the RF connector on the HD IN-CAR TX CAUTION Use an 8 in-lb torque wrench to tighten the SMA connector. Do not over-tighten.
418-1-001 3. OPERATING INSTRUCTIONS 3.1 Turning on the Power The HD IN-CAR TX does not include a power switch. To turn on the unit simply connect power to the POWER connector. 3.1.1 With No Control/Programming Cable Connected If the unit is powered while there is no connection to its UHF port, the HD IN-CAR TX goes into standby mode. 3.1.2 With Control/Programming Cable Connected If power is applied when the UHF port is connected as in section 3.4.
13418-1-001 3.2.3 Detailed Status Information Detailed status information for the HD IN-CAR TX can be displayed in the Digital Camera Control 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 Using the GUI 3.3.1 Connecting 1. Connect the laptop or PC to the HD IN-CAR TX using the Control/Programming cable provided.
13418-1-001 3.3.2 Hub Tab The Hub Tab of the Digital Camera Control software allows the user to select the transmit frequency and modulation parameters of the In-Car TX, as well as control power. It is detailed below: 1 2 3 4 1 – Power and Tx Enable The Power button toggles power for the unit. Tx Enable toggles power to the final RF transmit stage.
13418-1-001 Allows selection of COFDM modulation parameters. The user can select between QPSK, QAM16, and QAM-64 constellations as well as a variety of forward error correction code rates and guard intervals. For typical operation select QAM-16 modulation, ¾ code rate, and 1/32 guard interval. 3 – Frequency Selection Typical transmit frequencies are selectable from these drop down menus. First select the band of operation, then the channel, and then the offset (if any).
13418-1-001 3 – Dual-Stream Enabled Click this button to enable dual-stream. In this mode the two selected videos are independently compressed and modulated onto two adjacent COFDM pedestals (i.e. 16 MHz wide output). The channel frequencies will be +/- 4.25 MHz above and below the transmit frequency selected on the Hub Tab (see section 3.4.2). For example, if a transmit frequency of 1460.50 MHz is selected while in dual-stream mode, the lower channel will be 1456.25 MHz and the upper channel will be 1464.
13418-1-001 3.3.4 Custom Tab The Camera Tab of the Digital Camera Control software allows the user to select from all supported transmit frequencies rather than just those available on the Hub Tab. You will also notice that the bottom portion of this window is visible from all tabs if “Debug” is selected from the “Settings” menu.
13418-1-001 1 – Value This field allows user selection of the transmit frequency in 250 kHz steps. First, make sure that the “Decimal” radio button is selected in the bottom portion of the window and that SCOPE selects the desired frequency range (see “3 – Scope” below for more details). Change VALUE by either moving the slider or directly entering a number between 0 and 4095 in the field at the bottom of the window.
