Model 907PLUS Multiplexer


The 907Plus is a multiplexer that extends the capabilities of standard 907 motherboards with an added video channel, galvanically isolated data channels, and a comprehensive, integrated diagnostics network. System expansion is even easier with a rapidly growing family of compatible expansion cards and media converters. A diagnostics add-on card is available that offers end-to-end performance monitoring and identification for multi-card systems via an Ethernet connection at the console, and Graphical User Interface (GUI) software.

Expansion cards may be stacked on the motherboard to add up to 48 data channels in a variety of formats, including RS-232, RS-485/422, TTL, Ethernet, CAN Bus, analog sonar, hydrophone, audio, and Tritech ARCNET. Depending on transceiver options, optical power budgets are typically 20-26 dB with 10 km or more of singlemode fiber.
