Name 16QAM 64 QAM A/V C-OFDM CVBS Y C Pr Pb FEC MDT-B MPEG NTSC PAL QPSK RF SDI TX 100-M0058X2 Meaning 16-state Quadrature Amplitude Modulation 64-state Quadrature Amplitude Modulation Audio/Video Coded Orthogonal Frequency Division Multiplexing Color video base band signal (Composite video).
2.0 Introduction The inline camera mount box is an optional housing (for the MDT-B transmitter) which mounts to a professional A/V camera. The housings are designed to use either Anton Bauer or IDX batteries. The two line LCD (liquid crystal display) provides visual readouts of transmitter frequency, analog video lock status, COFDM mode, COFDM bandwidth, transmitter guard interval, forward error correction (FEC), video input type, audio status, audio gain and backlight status.

4.1 RF Output The MDT inline camera enclosure uses a female N type connector (flange mount) for its ‘RF Output’ port. 4.2 I/O The ‘I/O’ connector is a female, DB-15. It is used to provide the interface for RS-232 signals (control and monitoring). GMS MDLB Configurator software program makes use of the RS232 control lines, pins 2, 3 and 5 of the DB-15 connector. The RS-232 channel utilizes a 3-wire configuration. The pin out for I/O connector is shown in Table 2.
4.5 LCD Display Many of the control functions which are normally handled through the software interface and a PC are accessed directly with the front control panel and displayed on the LCD. 4.6 SDI Input (optional) A BNC connector is provided for Serial Digital Interface input data stream. 100-M0058X2 13 of 13 www.cobham.
