Ideally the low power 50mW mode should be employed to reduce the consumed power.
4) The antenna should be mounted vertically ideally, and exposed to free space. 5) The equipment should be supplied with a clean supply in the range 5.9 to 16V and capable of 0.4A maximum. Care should be taken to avoid direct supply from the vehicle 12V which can be very noisy. Power conversion will be required for 24V vehicles. 6) The video input can be connected across long video cable lengths so remotely mounted cameras should pose no problem.
The SOLO4 Bodywire transmitter has been successfully tested with a wide variety of standard and pinhole cameras. domo can supply cameras on request. The domo transmitter will become warm to the touch after prolonged operation, and so insulation between the operators’ body and the transmitter unit should be considered. The SOLO4 Bodywire transmitter has an IP66 rating, however equipment should not be exposed for any long periods to any form of liquids.
Powering on the System All external connection to the SOLO4 Bodywire transmitter should be made, as described in the previous sections, before proceeding to power on the system.
The displayed diagnostic data includes a spectrum display, signal to noise data, input power level and frequency. The received spectrum display is useful when checking for interference signals, the SNR indicated signal quality. For more information on use of this facility a domo training course is recommended. Using the OSD as a Set-up / Diagnostic Tool The On Screen Display (OSD) is an extremely useful tool for system set-up and diagnostic.
Using the SOLBAT The domo SOLBAT is used for powering domo transmitters. The domo SOLOBAT can not be connected directly to the Bodywire Transmitter, instead it must be connected using the SOLBCC adaptor cable. The SOLBCC adaptor cable provides an interface between the 4 pin DC In Lemo on the CA0317 transmitter break out cable and the 6 pin DC Out Lemo on the battery. The cable is shown below. When connected a fully charger SOLBAT will power the transmitter for more than 4 hours.
Approximately 2 hours should be allowed for a full charge of the SOLBAT battery. 1.4 Using the Clip On 1W Amplifier Additional range can be achieved by connecting the SOLAMP1W clip on amplifier to the domo Bodywire transmitter. Connections This section describes how to connect the following model numbers.
3. The 3 pin Lemo spur protruding from the PA to Bodywire adaptor cable, should be connected to the PA to provide power and PA enable. DC Power and Control Cable The SOLAMP is powered by the SOLO4 Bodywire TX and no additional power is required. However the voltage range when using the SOLAMP is more limited. • Input Voltage Range: 11-16V, reverse voltage protected. • Current Draw 1.2A (Includes SOL2/SOL4 TX) at 12V. Antennas Domo SOLAMP is supplied without antennas as standard.
Installation Notes The domo SOLAMP has been designed specifically for vehicle applications, however it is a general-purpose amplifier and can be used in many applications including the following. • Vehicle applications • Aircraft applications • Long Range fixed links Interconnection between the SOLAMP transmitter and the antenna, or any intermediate optional power amplifier should be kept as short as possible. Special attention should be taken to use only low loss cables.
• DC Power Cable RF Connection The domo AMP5W has the following input power requirements. AMP5W-115140: Input Power 100mW or 20dBm AMP5W-225255: Input Power 100mW or 20dBm Therefore care must be taken when connecting the AMP5W-225255 product to the SOLO4 Bodywire transmitter. Ideally when balancing the 5W Amplifier and domo transmitter a power meter should be employed, this will give best results, because cable losses can be factored.
