3/2/2005 - Fiber Mux Features "Virtual Channel Mapping"
Intended for SCADA & Process Control fiber optic redundant ring networks, a new 4-Channel Self-Healing Ring Multi-Drop Multiplexer from TC Communications features "Virtual Channel Mapping (VCM)."
VCM effectively enables users to run two independent communications networks in one self-healing ring topology. To summarize, VCM Benefits include (1) concurrent multiple networks; (2) cost savings by requiring less channels; and, (3) faster polling rates.
The offers 4 channels on the Master and 2 on each Slave. Its digital design is protocol transparent and offers a sophisticated self-healing ring scheme. If a fiber cable or device failure occurs, the data path automatically switches over within 50 msec. to the secondary path to maintain Ring network integrity.
Interfaces can be RS-232, RS-485 or RS-422. It is available with all popular fiber optic, power and connector options. Industrial Hardened versions (-40°C to 80°C) are available for extreme environments
