## Description

This is the RS-485 MicroLink-HM, a managed HART interface 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 - or use the free included HM Configuration app. See 101-0029 for the MicroLink-HM with RS-232 interface.

## Features

- Can be used as a standard HART protocol modem or HART to modbus accumulator
- RS-485 port can be set to standard baud rates from 1200 to 57600 O, E, N parity
- Complies with HART physical layer
- Use standard modbus commands to read HART device variable data
- Includes HM Configuration app, HART device addressing app, PACTware, and Microflex Generic HART DTM-6 on a CD
