USB
Connect one end of the supplied USB lead to the USB port on the logger and the other end
to a USB port on the PC.
On detection of the logger the PC will install the OM-SQ20XX USB device drivers
Win 7/Vista - USB Device Drivers are automatically installed and no further action is required
Win XP - During the installation the USB drivers were pre-installed so the wizard will
automatically locate the driver. On the ‘Found New Hardware Wizard’ select ‘No, not this
time’ and for all the other screens select ‘Next’ to complete the installation.
If you experience any problems refer to Troubleshooting->20XX USB Drivers in OMEGALOG® help.
