MiCROLiNK 101-0027 HART Protocol Modem
General Description
The MicroLink 101-0027 is a USB HART® protocol modem. It provides the hardware
interface between Highway Addressable Remote Transducer devices (HART) and a
Windows® PC with a USB interface. MicroLink is used for commissioning,
diagnostics, monitoring, and testing HART field devices. Virtual serial port
drivers allow the USB MicroLink to appear as an RS-232 com port to Windows and
your HART software. A rugged design makes MicroLink an ideal choice for field
engineers and technicians who service HART devices in an industrial
environment.MicroLink is compatible with all registered HART devices and all
leading HART configuration and monitoring software.
Driver Pre-Installation
The USB drivers should be installed before the MicroLink HART modem is connected to the PC’s USB port. AŌ er the drivers are installed, Windows will automatically detect the modem when it is connected to the USB port and complete the setup.
Important!
Install the USB driver before connecting to the USB port. To pre-install the
drivers, run Msetup.exe from the included CD. The CD will auto-run this fi le
if the Windows autorun feature is enabled for your CD drive. 
Click the Install button in the 101-0027 window to pre-install the USB
drivers. The driver installer will guide you through the setup process.
Installers can also be run manually from the CD, without running Meetup, by
running \x86\dpinst.exe fi le for 32-bit operating systems or x\64\dpinst.exe
for 64-bit operating systems.
Don’t have a CD drive?
Download the HART Protocol CD image from
www.microflx.com/pages/support
Running the file will self-extract the compressed files and start the
Msetup.exe HART Protocol Setup Utility.
Driver inf file – Manually Installed
To manually install the driver inf file…
- Connect the Converter to the USB port.
- Open the Windows Device Manager.
- The New Device Wizard will have added the converter under Ports (COM & LPT) and will appear as MicroLink HART Protocol Modem (COMx). Right-click the device and select Update Driver Software…
- Choose to Browse for the driver’s software and browse to the CD or the location of the MxHART.inf fi le.
- Follow the wizard prompts to complete the driver setup.
Uninstalling the USB Drivers
If needed, use Windows Device Manager to uninstall the driver from your
system. With the modem connected to the USB port, locate the MicroLink modem
in the Device Manager hardware tree under Ports (COM & LPT). Right-click on
MicroLink HART Protocol Modem and select Uninstall from the pop-up menu. When
the process has finished, unplug the modem from the USB port.
Finding the Assigned COM Port Number
When Windows installed the serial port driver the next available COM port number was assigned to the converter. The software you use with the converter must be set to use the same COM port number. To find the number assigned to your converter run Msetup.exe from the CD and click the Com Port List… button to show a list of found devices and assigned COM port numbers.
To use the list…
Unplug the modem from the USB port and it will be removed from the Com Port
List. Plug the modem into the USB port and it will be added to the Com Port
List. Set your HART soŌ ware to use the same COM number assigned to your
modem.
Using Windows Device Manager
The assigned COM port number can be found using Windows Device Manager. Open Device Manager and select View > Devices by Type. You may need to expand the Device Manager tree under Ports (COM and LPT) to see the converter. In the example shown below, the modem is assigned to COM 7. The assigned serial COM port number can be changed to any available COM port using Windows Device Manager. Expand Ports (COM & LPT) in the list to see which port the converter is assigned to. Right-click MicroLink HART Protocol Modem and select Properties from the pop-up menu. On the Port Settings tab, click Advanced. Drop down the COM Port Number list and select the desired port number. Click OK to use the new port number and close the window. Unplug the MicroLink modem from the USB port and then re-connect it to allow Windows® to update the USB device parameters. Click OK again to close the Properties window.
Software Setup
Make sure your HART software is set to use the same serial COM port number that the MicroLink modem is assigned to. There are no hardware seƫ NGS required by the MicroLink modem and modem power is provided by the USB port. All other seƫ NGS, such as BAUD rate and parity, are taken care of by your HART software.
Connecting to the HART Device
Connect the two mini-clips to the HART device or HART loop. MicroLink provides
electrical isolation between the HART loop and the PC. It is safe to ignore
grounding and polarity issues when making the HART connections. The HART
protocol requires a loop resistance of 230 to 600 ohms, typically 250 ohms.
Refer to your equipment installation instructions for details on connecting a
HART protocol modem or configuration of the device to the loop.
Two common methods for connecting the HART modem to a loop-powered device.
