Pacific Microwave Research, Inc. AT-100C3 User’s Manual © 2003 1.0 Introduction The AT-100C3 Microwave Video and Audio Transmitter from Pacific Microwave Research is a compact transmitter designed for short-range transmission applications under FCC Part 74, and Part 101. Common uses include law enforcement surveillance and electronic field production. The AT-100C3 is a compact unit designed for portable and field applications to transmit remote video to a central receive location.
Pacific Microwave Research, Inc. AT-100C3 User’s Manual © 2003 2.1.1 DC Power Input The AT-100C3 is designed to operate from a nominal +12 Vdc power source. Power is supplied through the front panel DB-9M connector (J3) with +12 Vdc on Pin 5 and Ground on Pin 9. This source should be fused at 2.0 A. The AT-100C3 will operate over a voltage range of +11 to +14.5 Vdc. Power consumption at the high power setting (2 W) is nominally 1.2 A. Power consumption at the low power setting (0.5 W) is nominally 0.7 A.
Pacific Microwave Research, Inc. AT-100C3 User’s Manual © 2003 3.0 Power Output The AT-100C3 is capable of operating at two power levels to fit a variety of operational scenarios. The high power setting is defaulted with no connection to Pin 1 of J3. The nominal power output on high power is 0.5 W. To select low power, Pin 1 of J3 must be connected to ground.
