Expansion Cards
The 914-HDE is a full multiplexing system capable of supporting 4 or more expansion cards simultaneously
through a multi-gigabit board-to-board expansion connector. A separate backplane card is not required. Focal
Technologies has developed a family of compatible expansion cards that allow the user to specify more signals
without adding more fibers. This reduces cost and size as compared to adding media converters or additional
multiplexer cards. The expansion connector has 4 medium speed channels and 2 low speed channels available.
The expansion connector provides for 16.15 mm spacing between cards when directly stacked together. For
tight spaces and/or larger stacks, Focal Technologies can provide high speed ribbon cables to allow cards to
sit up to 30 cm apart. Please contact your local representative for more information.
5.1 914-VDX
The 914-VDX (video and serial data expansion card) provides 2 channels of analog (composite) video and 4
channels of non-isolated serial data (RS-232, RS-485, RS-422). The video channels are compatible with both
NTSC and PAL standards. Diagnostics from this card are provided to the 914-HDE and are available to the
Model 914 Diagnostic GUI. This expansion card requires 550 Mb/s of bandwidth from the 914-HDE. This
expansion card requires 1 medium speed expansion channel.
