Communication Setup - Fourier TriLog User Manual

Communication Setup

TriLog communicates with the MultiLab software via a serial communication port.
Some users may find it difficult to select the correct port, in which case MultiLab can
perform an automatic port selection, and can also report on the status of all available
ports.
Automatic COM Port recognition
The PC has 4 communication ports, COM-1 to COM-4. One of these ports is usually
available for external communication. It is not necessary to know which port is
available, since MultiLab can find it for you.
Connect the communication cable from TriLog to one of the PC COM Port
connectors. In most cases, the port connectors are is located near the mouse port.
Use the 9)25 adaptor if the PC connector is of the 25 pins variety.
Turn on TriLog and run the MultiLab software. MultiLab will automatically attempt to
communicate with the data logger. If communication is achieved, the selected port
becomes designated as TriLog's communication port
If communication fails:
1. Select Comm Setup from the Logger menu. MultiLab will display a
dialog box reporting what COM Ports are already in use, and which
port is recommended for use with TriLog:
2. Click Try to connect and MultiLab will try to communicate with
TriLog. If communication is achieved, MultiLab will designate the
selected port as TriLog's communication port
You can override the MultiLab recommendation and choose the COM Port yourself
by clicking the check box button to the left of the desired port, and clicking Try to
connect.
Note: In case of any communication malfunction, please refer to Chapter
4: trouble shooting guide.
3. You can click Work offline if you wish to work without TriLog. While
working offline, you can still open saved files to view and analyze
them
