1. INTRODUCTION
This document describes the operations of the DPT 115 Digital Pan and Tilt head which is
designed for remote, long distance control requirements. This unit also provides presets for
applications needing camera and lens pre-programmed pan, tilt, zoom, and focus settings.
Applications such as teleconferencing, distance learning, tele-medicine and theater
instrumentation are all ideally suited for a DPT 115 installation. The DPT 115 is a lightweight
pan & tilt head designed to carry a variety of load configurations. The digital design of the
DPT 115 allows flexibility in lens selection and the adaptability necessary for special
requirements. Teleconferencing and CCTV lenses may all be easily interfaced to the versatile
DPT 115. Presets are available on the DPT 115 for pan, tilt, zoom and focus. The resolution of
the presets is 12 bits giving an angular resolution of 0.1 degree. Setup switches located at the
base of the unit make special functions and configuration changes easily implemented. A
family of digital controllers which may control from 1 to 5 DPT 115 Pan & Tilt Heads is
available. The Model 80, Model 88 and Model 180 family of digital controllers was
specifically designed to get the most from a DPT 115.

3. OPERATION
This section describes the operation of the DPT 115 and related system components. The DPT
115 receives serial data commands from one of two sources in all applications, a hardware
controller or a computer system. The pan and tilt unit will accept RS-232, RS-422 or both.
Functions of the pan and tilt include manual camera positioning, manual zoom and focus control,
and presets. Presets are stored pan, tilt, zoom, and focus positions that the DPT 115 will return to
automatically when recalled. The preset data is stored within the pan and tilt head. This data is
stored and recalled from the controller or computer system.
3.1 C
ONTROLLER
A controller is a device designed exclusively to provide ASCII serial commands to the pan and
tilt. These units generally have a joystick for up, down, left, and right direction commands. There
will also be some form of seesaw or switch controls for zoom and focus. Switches will also be
provided for preset control. The controller will transmit commands in RS-232 or RS-422
formats.
3.1.1 RS-422
RS-422 format is a balanced four wire interface. The signals are transmit plus, transmit minus,
receive plus, and receive minus. This interface is typically 26 AWG wire with a distance
limitation of 2000 feet.
3.1.2 RS-232
RS-232 format is a three wire single ended interface. The signals are transmit receive, and
ground. This interface is typically 20-24 AWG wire with a distance limitation of 100-200 feet.
3.2 C
OMPUTER
A computer can also be used to provide ASCII serial commands to the pan and tilt. Software
may be written to output the serial command over the serial port to remotely control the pan and
tilt. A computer program is available from the manufacturer that will allow a user to operate the
pan and tilt via the serial port of their personal computer. To obtain a copy of this program call
the manufacturer at the technical support center.
3.3 SYSTEM TEST
3.3.1 Power “ON” Test
Apply power to the pan and tilt electronics by activating the slide switch on the base of the pan
and tilt. The power green power LED should illuminate indicating the unit has DC power. The
red LED will flash once during power up.

3.3.2 Pan & Tilt Limit Adjustment
The pan & tilt head has separate adjustments for limiting pan-left, pan-right, tilt-up and tiltdown. The adjustment of these limits are described below.
NOTE: These adjustments are to be made after the controller has been interfaced to the DPT
115. The controller will allow one to move the pan & tilt head and check the pan & tilt limits.

4. SWITCH PANEL, CONTROLS AND INDICATORS
4.1 CONTROLS
4.1.1 Power Switch
A main power switch is provided at the switch panel of the pan and tilt head. When closed this
small slide switch provides DC voltage from the pan and tilt power supply to the electronics
located within the base of the head. The “POWER” LED will illuminate indicating that power is
applied to the pan and tilt head control electronics. The power switch is “ON” when it is in the
down position.
4.1.2 Setup Switch Pack
The eight “SETUP” switches are located adjacent to the power indicator on the pan and tilt
switch panel. These switches are labeled one through eight, the function of these switches are
defined in the diagram on the next page.

4.2 INDICATORS
4.2.1 Power Indicator-Green LED
The Power LED is located adjacent to the power switch on the pan and tilt switch panel. When
the “POWER” LED is illuminated, the power switch is closed and power is applied to the pan
and tilt head control electronics.
4.2.2 Data Indicator-Red LED
The red Data LED is located adjacent to the power switch on top of the power LED on the pan
and tilt switch panel. When the “DATA” LED is illuminated, data is being sent to pan and tilt, or
pan/tilt is in the process of going to a preset.
