CONNECTING TO A PC
Important Note: Only PipeIQ version 2.9.1 or higher can be
used with a FAAST LT-200. Other versions of PipeIQ will not work
with this detector.
A PC connection will only work when the FAAST LT-200 device is
in the Remote Maintenance mode. Always make sure that PipeIQ
is running on the PC and that the FAAST LT-200 unit has been set
to Remote Maintenance mode before connecting the USB cable.
IMPORTANT NOTE: See First time connection below when a new
PC or a new version of PipeIQ is used.
Remote Maintenance mode
To enter the Remote Maintenance mode, rst set the device to
Maintenance mode (see: Password access to Maintenance Mode
section). Then open the detector front door by releasing the two
Phillips screws. Connect a USB cable from the internal socket
in the centre of the device to a spare USB port on the PC; the
detector will now be in the Remote Maintenance mode.
Make sure that the USB connector is pushed fully into the FAAST
LT-200 socket – should feel a click. Check the integrity of the cable
before looking for other connection problems.
The USB connection must be made within 5 minutes of entering
the Maintenance password.
First time connection
The rst time a PC running PipeIQ is connected to a FAAST LT-
200 detector, the USB port drivers will be installed. Follow these
instructions carefully to avoid having to uninstall and reinstall the
PipeIQ software.
Before plugging in the USB cable, ensure that PipeIQ is running
on the PC (an open project is not required), and that the FAAST
