1. Operation of electronic equipment involves the use of voltages and currents that may be dangerous to human life Note that under certain conditions dangerous potentials may exist in some circuits when power controls are in the OFF position Maintenance personnel should observe all safety regulations Do not make any adjustments inside equipment with power ON unless proper precautions are observed All internal adjustments should only be made by suitably qualified personnel All operational adjustments are available externally without the need for removing covers or use of extender cards openGear INTRODUCTION Developed by Ross Video openGear is a standard where various manufacturers can design their equipment to fit a common frame allowing the end user to mix and match the various openGear cards available in the market place together in one frame This allows a single frame to be used instead of multiple different vendor s frames that each would otherwise be using their own proprietary standard A simple to use monitoring and control software called DashBoard is a free program downloadable from the openGear website www opengear tv that allows the user to remotely monitor and control an openGear type card fitted within an openGear frame that meets the openGear standard for DashBoard control A link is also supplied via the IRT Electronics website www irtelectronics com under the openGear navigation section IRT Elect2. 00 IRT 6170 AMS INSTALLATION Pre installation Handling This equipment may contain or be connected to static sensitive devices and proper static free handling precautions should be observed Where individual circuit cards are stored they should be placed in antistatic bags Proper antistatic procedures should be followed when inserting or removing cards from these bags Installation in openGear frame See details in separate manual downloadable from the openGear website www opengear tv Video analogue 3G HD SD SDI ASI G 703 data and unbalanced AES Signal Connections Signal connections are made to BNC coaxial connectors No termination of inputs is provided on the module When switched to the output the input load impedance is that of the load connected to the output Where the input signal is required to be terminated and one of the outputs is not connected to anything then this unconnected output should be terminated by an appropriate BNC terminator of the required impedance usually 75 Ohm OUT A 0 0 OUT B IRT Electronics Pty Ltd www irtelectronics com Page 8 of 18 Revision 00 IRT 6170 AMS Audio Signal Connections Audio signal connections are made to 5 pin plug in screw terminating connectors No termination of inputs is provided on the module When switched to the output the input load impedance is that of the load connected to the output There are four 5 pin audio connectors IN A OUT A Left
