3 Power on Apply 12V DC to DC-103. It will take about 40 seconds for DC-103 to boot. When the boot process is completed, it begins to transmit the camera video from the SMA connector in DVB-T, and the CVBS output is also present. Note: 1. Default RF channel is CH69, Frequency: 858MHz, BW:8 MHz, unless specified. 2. When initialization done, ###Camera Boot Finished### message will be shown in the UART debug port output; refer to more details below. Connect to a DVB-T receiver 1. Connect the video RF output to a coaxial cable (or an antenna). A DVB-T receiver can be either DVB-T TV, DVB-T STB or DVB-T USB receiver dongle. 2. The video output is full HD 1920x1080x30P H.264 format. Please make sure your receiver is capable of HD decoding. (Many old DVB-T STB s or TV s can only decode 720x576 SD). 3. Default RF channel is CH69, Frequency: 858MHz, BW:8 MHz, unless specified. 3

Connect to a CVBS monitor A CVBS video output is optional.

4 Adjust the Focus of the Lens By default the focus of the lens may not be correct. Please turn the lens clockwise or anti-clockwise to get the best focus. Connect to a CVBS monitor A CVBS video output is optional. If it s enabled, when the system boot is completed, there is a standard CVBS video output (default PAL). 4

Note: By default MIC-in feature is disabled.

5 Mic-in If it s bare bone DC-103, a condenser microphone is included. If DC-103 with housing, a 3.5mm Phone Jack is provided. Note: By default MIC-in feature is disabled. When you want to enable MIC-in feature, it s recommended to disable CVBS output with the configuration kit for better audio quality. 5

6 USB UART PORT The USB UART port can be used to configure DC-103 or monitor the system boot status. You may connect the UAB UART to a Laptop PC. On most Windows platforms, the driver will be installed with in-box driver automatically. However, if Windows prompts to install driver for the new device, please run PL2303_Prolific_DriverInstaller_v1.7.0.exe, which can be found in the folder \PL2303_Prolific_DriverInstaller_v1.7.0 If the device driver is installed well, there will be a new Com Port device, shown in Windows Device Manager. The com port assignment may vary depending on the PC configurations. In the following example, COM5 is assigned. The following picture show how the USB UART dongle is connected to DC

UART terminal application to monitor debug message.

7 Monitor Boot Messages When you connect the USB UART port to a Laptop PC, and driver is well installed, you may use any UART terminal application to monitor debug message. The default communication parameters are ,n,8,1. 7

8 Custom Configuration Users may customize the configurations with a PC tool thru the USB UART port. Connect the USB UART port to a Laptop PC, and make sure driver is well installed as described in previous paragraph. Launch ite_serialtool.exe. Specify the correct COM port which corresponds to the USB UART port, then click on Open button. The following shows the USB UART port is open successfully. Click on Get button to retrieve current configurations. 8

If it fails to open the COM port, it shows the following message on the caption bar. Please check if the USB UART Port is currently open by any other UART terminal application.

9 If it fails to open the COM port, it shows the following message on the caption bar. Please check if the USB UART Port is currently open by any other UART terminal application. Modulation Setting Description Note: When you change the modulation settings, you needn t to reboot the camera after clicking on Set button. The new settings take effect immediately.

Range: -25 ~ +5 In Kbps, find details below. Note: it s recommended that the [Video Bitrate] should be less than [modulation data rate] by 20% at least. If [modulation data rate] is too low, it may cause video glitch. [1] [2] [3] auto The modulation data rate ( channel capacity, maximum data bit rate or throughput) varies depending on the transmission parameters. The maximum date bit rate can be calculated as below. Tbandwidth = {1000,000, 2000,000, 3000,000, 4000,000, 5,000,000,6,000,000, 7,000,000, 8,000,000} in Hz for 1~8MHz Tcode_rate = {1/2, 2/3, 3/4, 5/6, 7/8} TConstellation = {2, 4, 6} <- QPSK = 2, 16QAM=4, 64QAM = 6 TGuardInterval = {4/5, 8/9, 16/17, 32/33}, 1/4 = 4/5, 1/8 = 8/9, 1/16 => 16/17, 1/32 => 32/33} 2K/8K mode does not matter Maximum bit rate = 1512 / 2048 * 188 / 204 * 64 / 56 * TBandwidth * Tcode_rate * TConstellation * TGuardInterval (bps) = 423 / 544 * TBandwidth * Tcode_rate * TConstellation * TGuardInterval (bps) Refer to the table shown below.
