CamPac2 M13-0003-00A Description 8
CamPac2 Description control panel uses a unique rotary dial that senses the position of the user’s finger when pressure is applied and rotated around the disk. By dialing around the wheel and using the (Esc) ▲and (Ent) ▼buttons, you can navigate through the menu system. 1.0 DESCRIPTION The CamPac2 is a small lightweight HD/SD COFDM microwave transmitter intended for wireless camera applications including sports coverage and electronic news gathering (ENG).
CamPac2 Description The “IQ” based CP2 can be factory configured for either News or Professional use, depending on the encoder style installed in the Base. This configuration is not field selectable or swappable, and the customer must specify either the “N” or the “P” style when ordering. . The News (N) style CP2 supports very low latency operation as required by broadcasters for live shots, with superb fidelity.
CamPac2 Features 2.2 PROGRAMMABLE OUTPUTS 2.0 FEATURES The CamPac2 utilizes four programmable presets to allow rapid selection of different transmitter parameters. These are fully configurable and can be modified via the Front Panel sensor wheel and LCD menu selections. For more information on Presets, see the section in this document entitled, Presets. The CamPac2 was specifically designed for portable use as a camera back transmitter or in helicopters applications.

CamPac2 Installation Embedded digital audio is input through the BNC connector. This requires that whenever Embedded is selected as the audio source, SDI must be selected as the video source. 4.4 CONNECTIONS Video: The video inputs to the CamPac2 are either through the 12 pin LEMO connector or a 75Ohm coaxial cable with BNC connectors (See Figure 6). Connect the video source to the appropriate video input: Power: The CamPac2 normally receives power from an external “clip-on” battery.
