InLink-HM OEM HART Protocol Modem

Microflex, 101-0014, InLink-HM OEM HART Protocol Modem with Modbus RegistersInLink-HM is a complete HART modem module that can be used as a primary or secondary HART master - eliminating the need for external carrier detect (CD) monitoring and request-to-send (RTS) control. It can also be configured to continuously poll up to 16 HART devices, filling internal modbus registers with variable values. The variable values can then be read as 16-bit signed integer or single precision floating point using modbus-RTU commands. Configuration is saved in modbus registers allowing modbus commands to be used for configuration. InLink-HM uses the same modem and core processor that the MicroLink-HM modems use.FeaturesCan be used as a standard HART protocol modem or HART to modbus accumulator for OEM applicationsSmall 1.1" x 1.25" PCB footprint - same pin-out as InLink-TC modemThrough-hole or socket mountingLow-power 3.3 volt supplyHART communications status output pinSerial port can be set to standard baud rates from 1200 to 57600 O, E, N parityComplies with HART physical layerTransformer isolation simplifies loop connections and eliminates grounding effectsUse standard modbus commands to read HART device variable dataFree HM Configuration app and HART device addressing app availableFree PACTware and Microflex Generic HART DTM-6 availableCompatible with the 101-0003 InLink evaluation board.
