20 Ignite SDC/HDC Robotic Camera Instruction Manual
Section 1 — Overview
The robotic head processes the pan and tilt inputs and moves the camera to
the commanded location. It passes zoom and focus commands to the lens
assembly. It also provides a communication path between the camera head
and SHOT Director (for configuration and status monitoring), and pro-
vides 12 V dc to power the camera block.
The camera block receives 12 V dc power from the robotic head, tally (red
and amber) dry contact control from a tally controller, and facility supplied
gen-lock (sync). The camera provides iris control to the lens assembly,
status and configuration menu access to the SHOT Director (through the
robotic head assembly), and produces SDI video out to station switching
and processing equipment.
Robotic Camera and SHOT Director
Robotic camera control requires connection to a JSC-2300 SHOT Director
robotics/camera controller through a network hub. (

The SHOT Director can control up to 16 cameras. It provides the camera
trigger and preset/manual control commands (pan/tilt/zoom/focus) to
the robotic head. Camera presets are created and stored in the SHOT
Director. You can also access and make configuration changes to the
camera block settings menu with the SHOT Director.
