1 GENERAL SAFETY INFORMATION The information that follows, together with local site regulations, must be studied by personnel concerned with the operation or maintenance of the equipment, to ensure awareness of potential hazards. WARNING- RF Power Hazard : High levels of RF power are present in the unit. Exposure to RF or microwave power can cause burns and may be harmful to health. Switch off supplies before removing covers or disconnecting any RF cables, and before inspecting damaged cables or antennas.
The unit is supplied with a 4dBi antenna that is fitted to the rear of the camera. The FCC RF Exposure Evaluation has determined that a 20cm minimum safety distance must be maintained between the antenna and all persons in the area. Use of the unit with an external mast mounted antenna and / or power amplifier requires separate RF Exposure Evaluation.
2 INTRODUCTION This manual is to be used in conjunction with the D-Cam Clip-On unit (CCAM-0104) which replaced the original 0101 & 0102 variants. The upgrade from 0101 to 0102 added the extra feature of an SDI input. The upgrade from 0102 to 0104 added the extra features of frequency selection to 0.5MHz increments. For details of the receiver please refer to the relevant manual.

3.2.3 Ch / Frequency Menu This menu is used to select one of the sixteen pre-channels (CH1 – Ch16) or ‘manual’ frequency. The ‘Man’ setting allows control of the transmit frequency in 0.5MHz steps within preset limits. These limits can be confirmed using the Remote PC Interface See 6.2 for details. The Enter button allows the ? ? buttons to select the required digit, the ? ? buttons then select the required value. The Enter button then stores the value and returns to the Main menu. 3.2.
3.3 Status Monitoring There is a red/green ‘status’ LED indicating the condition of the D-Cam Clip-On, if a fault or warning exists the LED will indicate Red and the Status menu will indicate the nature of the fault / warning. During initialisation of the unit the Status LED will be off. The Status LED flashes RED to indicate a warning. This is due to: No Video Input. Check the camera is switched on and the video lead is correctly connected The PA is turned off.
3.4.4 Video Format The ? ? buttons are used to select the required video input format of either PAL (625/50) or NTSC (525/60). The Enter button then stores the value and returns to the Main menu. 3.4.5 Temperature A display in degrees Celsius of the internal temperature of the D-Cam Clip-On controller.

4 PREPARING FOR OPERATION EQUIPMENT PREPARATION Before leaving the equipment base to undertake an operation it is recommended that the following equipment checks be made. 4.1 The D-Cam Clip-On Camera Back Check that the Camera Adapter is securely fastened to the camera. Check that the batteries to be used are fully charged and that an emergency spare battery is available and fully charged. Confirm the correct frequency is selected 3.2.3. Confirm the correct Encoder mode of operation is selected. 3.2.
Make sure that all batteries to be used are fully charged and whenever possible, provide a spare with the cable to connect it to the Receiver. Check that the Receiver channel frequencies are compatible with those of the D-Cam Clip On Transmitter and set the channel selector switch to the channel number required. The Receiver is labelled with channel number and frequency information.
5 D-Cam Clip-On Transmitter The D-Cam Clip-On is based upon the highly successful Gigawave D-Cam dockable Wireless Camera system. Internally, it is very different! Gigawave engineers have completely redesigned the D-Cam to compress all the circuitry on from five circuit boards onto two. This greatly reduces space and weight compared with the original D-Cam product. The result is a Digital Wireless Camera system, which has exceptional RF performance, is well-balanced and easy to use.

5.2 Audio / Video Encoder The Encoder board consists of the following main functions: • SDI to Digital deserialiser. Converts the SMPTE-259M-C serial digital video input to an 8 bit parallel digital video bus. • Analogue to Digital Video Converter, 10-bit over sampling ADC. Takes either Composite Video (75 ? , 1v p-p) (CVBS); YC or YUV inputs in either PAL / NTSC format and converts to an 8-bit parallel digital video bus.
5.3 COFDM Modulator “Coded Orthogonal Frequency Division Multiplexing – a modulation scheme which is used by the DVB digital television system.” The COFDM modulator has been designed to take its input from the MPEG2 encoder. This Transport stream is then modulated directly to the 2.5GHz band. This method reduces the occurrence of intermodulated harmonic frequencies and requires less upconvertors to reduce microphony. The COFDM modulator RF output is via the SMB connector.
5.4 Power Amplifier The function of the power amplifier is to amplify the signal from the COFDM modulator to a suitable level for transmission via the N-type connector into the antenna. The amplifier is required to be highly linear to accommodate the multiple carrier signal formats employed for digital system operation, with very low distortion (low intermodulation between carriers). The nominal output power is +20dBm (100mW) across the 2.2 – 2.7GHz band.

6 System Monitoring / Setup Using a PC running Hyper Terminal or other terminal emulator, the D-Cam Clip-On can be configured without the use of the operator controls and LCD display. The current configuration can also be obtained via this RS232 interface. When the D-Cam Clip-On is under the control of the Remote Interface the operator controls will not function when a menu has been entered. Set the terminal emulation for RS232, 19200 Baud, 8bit, 1 stop, No parity.
