1.0 Introduction
Focal's Model 903 is a video/data multiplexer and fiber optic transmission system designed for Remotely
Operated Vehicle (ROV) applications. The Model 903 uses Time Division Multiplexing (TDM) and Wavelength
Division Multiplexing (WDM) to provide high multiplexing density in a compact, low-power package. Typical
systems support 4-8 broadcast quality composite video channels, up to 64 digital channels, and additional
bidirectional optical channels for high-speed sonar, digital video, or 10/100/1000 Mbps Ethernet links.
The high density version of the Model 903 has been optimized for very high multiplexing density in an
extremely compact, low power package capable of delivering high quality video end-to-end. It supports up to
8 video channels of uncompressed, digitized composite video as well as up to 8 RS-232 channels and 8
plug-in modules, which may be selected from a range of modules including RS-232, RS-485/422/TTL, analog
sonar (MS900), hydrophones, Tritech sonar ARCNET and CAN Bus.
This user’s guide provides complete information on the design, configuration, installation and
operation of Model 903 High Density (HD) multiplexer
systems. All 903-HD systems presented in this
document are based on the new FMB-X-2.5 and –X backplane boards. System specific information
can be found in the 903-8xxx-xx installation drawings provided with your system.
This manual and the appropriate reference documents should be reviewed prior to installation or
reconfiguration of the multiplexer
.
Card or PCB assembly numbers are given in the titles of the corresponding sections of the manual.
Card assembly numbers refer to a complete printed circuit board assembly (PCBA) plus front panel,
optics, and assembly hardware, and are in the 903-00XX-XX and 903-5XXX-XX series.
PCBA numbers apply to populated boards alone, such as backplanes and AIB plug-in modules, and
are in the 903-02XX-XX series.
Appendices include the following information:
APPENDIX A – CONNECTOR PART NUMBERS AND PIN ASSIGNMENTS
APPENDIX B – FUSES
APPENDIX C – INSTALLATION DRAWINGS
APPENDIX D – ISOLATION, PROTECTION, AND GROUNDING
