Setup COM Port

The RS-485 MicroLink-HM so  ware must be set to use the same 
COM port that the modem is connected to.  From the top menu 
select 

Setup>Com Port

. Choose the COM port number from the list of 

available ports. A  er choosing, click 

Connect

 to a  empt to connect 

using the se   ngs selected. The connec  on process will 

fi

 rst try the 

last good baud rate and parity se   ngs.  If it fails to connect the 

process will work through 
other se   ngs to try to 

fi

 nd the correct RS-485 

MicroLink-HM se   ngs for 
communica  ons.  If it s  ll 
does not connect - verify 
that you have chosen the 
correct COM number, 
connec  ons are correct, 
and power is on before 
trying again.

RS-485 MicroLink-HM HART - Modbus Accumulator

In addition to being an RS-485 HART Protocol Modem, the MicroLink HM can be set to collect and store process 
variable information from up to 16 HART devices.  HART devices are continuously polled and variable information is 
accumulated into a table of Modbus registers. Using the RS-485 MicroLink-HM serial port, the registers can be read 
using Modbus RTU command 3. Variable data can be read as 16 bit integers or 32 bit 

fl

 oating point. Up to 4 variables for 

each polled HART device.

In the accumulate mode, RS-485 MicroLink-HM will function as a HART master (primary or secondary) polling devices 
and storing variable values into registers. No additional HART software is needed. The HART loop may contain a single 
device or up to 16 devices.  When more than one device is in the loop each HART device must have a unique HART 
polling address.  The address for each device is set before wiring the device into the multi-drop loop.  The device polling 
address for each device is stored in the RS-485 MicroLink-HM using the RS-485 MicroLink-HM con

fi

 guration software.

Modbus slave address, baud rate, parity, and other settings are set using the RS-485 MicroLink-HM con

fi

 guration 

software. Con

fi

 guration is done using the same connection that Modbus will use, so no additional setup cable is re-

quired. After the con

fi

 guration is completed, the port is connected to the Modbus controller. At power on the RS-485 

MicroLink-HM will begin polling and accumulating values.  Modbus RTU command 3 is used to read the accumulated 
values.

MicroLink HM Installation - Windows

The RS-485 MicroLink-HM con

fi

 gura  on so  ware is included on a CD with the unit.  Simply insert the CD and follow the 

on-screen prompts to install the so  ware.  If AutoRun is not con

fi

 gured to run the CD 

fi

 le when the CD is inserted you 

will need to navigate to the 

Msetup.exe

 

fi

 le on the CD and double-click the 

fi

 le name to run it.

A  er Installa  on the HM Con

fi

 gurator icon will be added to your system.
