4.0 PC PORT
The VLC485 uses the PC port to communicate with the serial communications 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 addi-
tion, 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.
