Downloading system prints to a laptop
About this task:
Downloading system histories to a file is another useful method to capture system operating
conditions. The following instructions are used to establish communication between the
OptiView Control Panel and a laptop computer running any Terminal Emulation program such as
HyperTerminal, TeraTerm, or PuTTy.
1.
Connect the laptop computer to the OptiView as described below. If your computer does not
have a RS-232 serial port, you will need a USB to serial converter such as the Digi Edgeport/1.

printer selections. SETTINGS should match the Port settings below.
3.
Set up the Terminal Emulation program.
a.
Set the Com port for the port that the USB/Serial adapter is installed on.
b.
Set the Com port communication parameters as follows:

If DTR/DSR is used, set to Hardware.
If no DTR/DSR, set to None.
4.
Set the Terminal program to capture a file, and select the location and enter a file name.
5.
Press the Print Screen key on the appropriate screen to be captured. The HyperTerminal will
display the printed information and the information will be recorded as a .txt file.
Note: Since the menu options of the various Terminal Emulation programs are different,
the user will need to determine the exact steps required to save a file to their PC using
the desired program.
What to do next:
The following additional RS232 connections are used to wire up serial devices for desktop and
laptop computers.
