Troubleshooting Guide

Language: English ▾

Levelogger Software:

  1. You must have administrator privileges to install software on a computer.
  2. Windows 7, 8, and 10 Operating Systems support Levelogger Software.

Levelogger data has been accidentally erased:
If the Levelogger has been restarted and the old data has not been saved, select the download option "Recover Previous Log". This will download your previous data set.


Communication Errors:

"Port Cannot Open", "Check Com Port"

1. Reason: Software was started before USB device was connected to computer.
Solution: Restart computer, connect USB device, start software.

2. Reason: Incorrect Com Port is selected in Com Port selection menu.
Solution: Check the Com Port location for the installed device, by accessing the ‘Device Manager’ (through the Control Panel), and selecting the "Ports” section. This will state the Com Port the device is installed on.

3. Reason: Another device shares the same Com Port or is causing a communication conflict.
Solution: Ensure that software for PDA or other devices, which automatically synchronize, are disabled. Ask your system administrator for assistance.

4. Reason: RS-232 Adaptor to USB converter is improperly installed.


Not all converters are compatible with all makes and models of computers.

Solution: Reinstall supplied driver for converter device.

"Communication Time-Out", "Communication Error"

1. Reason: Levelogger, Direct Read Cable, or communications device has failed.

a) Narrow down the failure by using a different Levelogger, Direct Read Cable, or another communications device.

b) Clean the optical "eyes” on the Levelogger and the cable, with a soft cloth.

c) Check that the communication cable is connected to the same Com Port that is chosen in the upper middle of the Levelogger Software window.

Check the Com Port settings. They should be as follows:
• Bits per second: 9600
• Data bits: 8
• Parity: None
• Stop bits: 1
• Flow control: None

d) Try using a different computer, to see if this is the cause of the problem.

e) If using a laptop (especially in conjunction with a Direct Read Cable) your Com Port may not be powered adequately to receive/transmit data. Try using a desktop computer to test this.

f) If problem persists, contact Solinst.


All Leveloggers should be deployed and stored with the installation cap or direct read cable attached. This prevents unnecessary battery drainage and protects the optical eyes.
