Troubleshooting

Problem:

Will not communicate

Verify the following:

1.Com port number in application is the HM-BT-VIN com port number.

2.Loop power supply is on.

3.Loop resistance between 250 ohms and 1Kohms.

4.Loop current within HART limits.

5.If multi drop configuration, all transmitters in loop have unique addresses.

6.HM-BT-VIN HART connections across loop resistor or across transmitter terminals.

7.Modem power is on and the Red power LED is illuminated.

8.Perform the “Discovery” procedure again and verify a connection can be made.

9.If using the Linksys USBBT100, verify the Linksys Bluetooth driver is installed and not the Windows Bluetooth driver. There is a known issue with the Linksys install and Windows XP SP2. Go to www.linksys.com and search for “USBBT100” for details.

10.Press and hold the front panel Reset button for 5 seconds.

Problem:

Communications unreliable

Verify the following:

1.You are in radio range of the master transmitter. For Class 1 master devices 300 ft, for Class 2 master devices, 25 ft.

2.Vary the orientation of the master transmitter or the HM-BT-VIN to improve radio link strength.

3.Power supply meets the minimum requirements outlined in the “Power Supply” section of this manual.

4.Transmitter not in Burst mode. Communications can occur in Burst mode, but more retries will be necessary for success.

5.In some applications, a connection can be lost, which looks like a communication lock- up. Perform the Discovery process again to reestablish the link without the need to restart your application. When a link is lost the Blue LED will flash.

6.Press and hold the front panel Reset button for 5 seconds.

Problem:

Will not communicate with Cornerstone

Perform the following:

1.In directory “CSCONFIG/DB”, open file “CSLOCAL.INI”.

2.Search for “[RDLS2]” without the quotes.

3.Change “Debug=0” to “Debug=8”, again without the quotes.

4.Save the file.
