TC2850
Multi-Drop Fiber Multiplexer w/Virtual Channel Mapping
Features
Featuring Virtual Channel Mapping, the TC2850 Serial Data Multi-Drop Fiber Multiplexer enables concurrent applications, cost-saving benefits & reduced polling time.
Channel Mapping enables users to configure specific channels from the Master to designated Slave units on a fiber ring network. For example, it provides two independent communications networks within one self-healing ring topology, enables cost savings through flexible channel configurations and supports faster polling rates.

Applications
Because the TC2850 effectively enables two independent communications networks in one self-healing ring topology, it can be used to run multiple applications concurrently. For example, it enables virtual pointto- point configurations, such as a dedicated telephone circuit, within a Self-Healing Ring network (See diagram on back page).
It is also used in larger networks, with multiple port SCADA Host Controllers, to speed up polling times. Typical application environments include SCADA, Traffic Control, Process Control, Security, Oil & Gas, and Energy Management.
