SSC-5000 User Manual September 21, 20046Installation and OperationUnpackingBefore your camera is packaged for shipment it is rigorously tested and inspected. The camera isthen carefully packaged to withstand the rough handling that can be anticipated during shipment.System SetupWARNING: Whenever AC power is used in the vicinity of water, we strongly recommend thata Ground Fault Interrupt (GFI) equipped power strip is utilized to minimize the chance ofelectric shock due to a short circuit.To perform a system setup and test you will need to have the following components:1. Your SSC-5000® camera.2. A suitable mating connector (preferably the cable to be deployed).3. A video monitor.4. A video control unit and/or power supply.Power RequirementsThe integrated voltage regulator allows the SSC-5000® to operate on variable direct current(DC) between 9 and 30 volts. In operation the SSC-5000® draws less than 500 mA. Whencalculating voltage drop remember that you must account for the loop resistance, twice thelength of the cable. To calculate voltage drop on any length RG/59 coax and/or 18/5 SO cable,for example, use the following values and formula. Please be sure to use the correct resistancevalue for the cable you will be deploying with your SSC-5000®.Resistance of RG/U 59 coax per foot (typical): 0.0025 OhmsResistance of 18/5 SO cable per foot (typical): 0.0067 OhmsCurrent consumption of SSC-5000® (typical): 0.160 Amperes @ 12 VDCTo determine voltage drop apply the formula Volts (V) = Resistance(R) x Current (A) (amperes).An example: To determine the total resistance experiences on 1000 feet of RG/U 59 coax multiply:(0.0025 x 1000 x 2) = 5.0 Ohms Total cable resistance = 5.135 Ohms To determine voltage drop over the cable multiply:(5.135 x 0.160) = 0.822 volts Power supply must deliver a minimum of 12VDC + 0.822VDC = 12.82 VDC Your power supply must be at least 12 volts plus the amount of voltage drop. Recommendedvoltage is 18 VDC.If there is any uncertainty as to the voltage being produced by the power supply, test and make adetermination of output before placing the unit in service.Connector Pin OutBH4MP1 = Ground2 = Power3 = Video4 = Not Used
