Six methods are available for connecting TruTrack loggers to OmniLog (Note: Only the USB or RS232 options are available in Omni7):
TruTrack loggers can connect via a USB port using the DLC#USB download cables.
Connect directly to the logger using a USB or RS232 port of the computer.
Cable codes for the various types of logger are as follows:
|USB cable code:||
|RS232 cable code:||
Many computers do not have a dedicated serial port which means that USB is the only connection method available. We strongly recommend connecting TruTrack loggers via a USB port using the DLC#USB download cable appropriate for the logger type; otherwise USB connection is also possible using a USB to Serial adaptor and the DLC# RS232 download cable appropriate for the logger type.
Intech Instruments Ltd have tested using many types of USB to serial adaptors on different computers and have no problems connecting with TruTrack loggers.
However, we are unable to provide assistance for a particular adaptor beyond the information below. We strongly recommend using a DLC#USB download cable appropriate for the logger type for connecting via USB!
You will need to install drivers that come with the USB to Serial adaptor you are using. After the drivers are installed, you will need to check that the computer has not allocated the RS232 port a number above 8.
This is because OmniLog's autodetect only looks at the first 8 comm ports.
If it has been allocated a port number greater than 8 this can be changed in:
Start > Control Panel > System > Hardware > Device Manager > Ports (COM & LPT) > USB Serial Port (COMx)
When using OmniLog, we also suggest that you check the following as per this picture (under Tools > Options [Comms Tab]):
If the Logger Comm Port is set to Comm1 and the USB to serial adaptor is using a different port then OmniLog will not connect to the logger. The easiest way to find out which is the correct port to use is to click the ‘Auto Seek Comm Port’ button as per the picture (with the logger attached to the adaptor using the appropriate download cable). The logger should then be automatically detected. You can then click on the appropriate port that the USB to serial adaptor is using.
Also please note that many USB to serial adaptors do not supply power - these will NOT work with loggers that require a powered serial port (i.e. the GP-MC).
