4.0 PC PORT
The VLC485 uses the PC port to communicate with the serial com-
munications port of a PC or modem. The PC or other connected
device uses a protocol to control either the VLC485 or other devices
connected to the VLC485, such as the pan/tilt units. In addition, all
controller activities, including joystick movements, are transmitted to
the PC port. This enables the controller to become a “peripheral” to
a PC and act as the man/machine interface for a system. Following
are the VLC485 protocols.
