Hart Multiplexer

May 1, 2004
The MUX2700G Hart Multiplexer provides 32 single channels for connection to “smart” transmitters or control devices, while supporting HART standard digital communication.

The unit is fully compatible at the interface level with all previous MUX2700 versions, and functions at RS-485 communication speed, with standard operation at up to 38.4 Kb/sec. Additional features include a fully redesigned processor board with single-chip microprocessor, providing more memory for future expansion; redesigned firmware, offering better performance, consistent behavior in all operating conditions and simplified firmware upgrades, and; a firmware download capability that facilitates 20-second downloads via RS-485 line without having to remove the unit from the termination board. These multiplexers offer channel-to-channel isolation and eliminate complicated master/slave configurations. They serve as gateways between workstations and field instrumentation by interrogating each field device under workstation supervision, and storing the information in their internal database for quick, easy access.
