LANC is a single-wire, one-way digital protocol used by Sony, Canon, JVC and Blackmagic on
many of their cameras.
Panasonic Remote is a two-wire, one-way analog protocol for many Panasonic models.
Both of these are limited because they provide no feedback to the controller regarding the
position of the zoom, or the current focus or iris settings.
VISCA is a bi-directional serial protocol that uses three types of physical connections
depending on the controlled device: RS232, RS422 and RS485.
So you use the MODE switch to select both the CONTROLLER and the CAMERA. This label is
affixed to the top base of the PTX so you can set the DIP switches to the appropriate
positions.
