Communication 4-53
2. Attach the serial connector end of the cable to the proper serial
port on the laptop computer.
Note: If your computer has a USB port and no serial port,
run a USB-to-serial adapter cable (and driver software)
between the Direct Connect Cable and the computer to
perform serial communications. IETG recommends the
following USB adapters: Dynex (model DX-UBDB9) and
Keyspan (model USA-19S).
3. Designate the appropriate local port on the computer for
communication through the Profile or Qstart software. For a
serial connection, designate the local serial port. When using a
USB-to-serial adapter cable, designate the local USB port. It
will be different than the serial port. For more information,
refer to the Profile User's Guide #950015 (version B4 or
higher).
Note: The serial port on some older computers may not
provide adequate power for the Direct Connect Cable to
facilitate communication with the monitor. A USB-to-
serial adapter cable can regulate the power going to the
Direct Connect Cable, providing sufficient energy for
communication. Therefore, if the serial port is preventing
communication and a USB port is available on the
computer, use a USB-to-serial adapter cable (and driver
software) with the Direct Connect Cable to communicate
successfully with the monitor. Refer to the previous note
for adapter cable recommendations.
