C adapter, and target system.
• If you are using a laptop computer or host computer that is NOT connected to
mains earth ground, make a hard-wired connection from the host computer (i.e.,
port connector shell) and the target system ground connector to a common earth
ground point.
• Avoid plugging and unplugging system components while the host computer or
target system is powered.
• Ensure that any devices connected to the target system are properly grounded to
the common earth ground point.
• If unsure how to properly ground system components, seek electrical expert help.

5 Virtual ComPort
Communication between a host computer and the iPort/LAN 2 is based upon a
Virtual ComPort (VCP) driver installed on the host computer, and a network
connection between the host computer and the iPort/LAN 2. The VCP driver
associates a host computer ComPort number with the network address of the
iPort/LAN 2. Once the VCP driver is installed, the host computer uses the Virtual
ComPort to communicate with the iPort/LAN 2.
A host computer can establish communication with an iPort/LAN 2 three different
ways, Direct Connect, Local Connect, or Remote Connect.
Direct Connect provides a direct connection between the host computer and the
iPort/LAN 2. A Virtual ComPort (VCP) driver is installed on the host computer,
and an Ethernet Crossover Cable is used to connect the iPort/LAN 2 to a wired
Ethernet Port on the host computer. During VCP driver installation on the host
computer, the iPort/LAN 2 is assigned a Static IP address and a ComPort number.
