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.
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.
Tilt Adjustment View B illustrates the location of the Tilt Up and Tilt Down Limit Adjustments. With the camera mounted on the pan & tilt as shown in Figure 3, turn the system power “ON” and move the JOYSTICK up until the rear of the camera nears the bottom of the pan & tilt. Make sure the camera does not hit the pan & tilt when tilted fully up.
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.

5. CONNECTOR INFORMATION 5.1 CONNECTOR PANEL 5.1.1 Lens I/F Connector: NOT USED JVC Configuration The connector labeled “LENS I/F” on the connector plate is an eight mini DIN female (socket) type. This connector provides signals to and from the camera lens in special applications. Internal wiring for this connector can be found on the MPU Module schematic diagram and is directly wired to the 8 pin DIN connector located on the body of the pan & tilt.
5.1.2 Communications Interface Control of the pan and tilt is accomplished by sending packets of ASCII characters to the head. The standard communications protocol is 9600 baud, eight data bits, one stop bit , and no parity. These commands tell the head and lens which direction and at what rate to move. Preset related commands are also passed over the communication link between the head and the controller. In most cases the communications link is either RS-422 or RS-232.
5.1.4 RS-232 Connector The connector labeled “RS232” on the connector plate is a nine pin sub-miniature female (socket) “D” type. This connector provides data for either the LDCC option or a RS-232 computer interface to the digital pan and tilt head. The pin numbers for the RS-232 connector are clearly labeled on the connector. Internal wiring for this connector can be found on the MPU Module schematic diagram.
5.1.5 +15 VDC Power Jack This connector provides the DC power required to operate the pan and tilt head. The connector type is a Switchcraft 722 series. The outer conductor is for 15 VDC, the center conductor is ground from the power source. The pan and tilt head requires a power supply capable of a minimum of .8 amps at 15 DC. The power connection to the pan and tilt head is made via a 5.5 mm X 2.10 mm female DC plug located on the power supply. Caution: the center pin of this jack is ground.

5.3 DPT JUMPER INSTALLATION. It will be necessary to disassemble pan and tilt mechanism from base of DPT unit to gain access to the configuration jumpers on the MPU PWA. The MPU PWA is the top board and will be accessible as soon as the pan and tilt mechanism is removed. The following steps describe reconfiguring the jumpers. The equipment necessary for this procedure are a No. 2 Phillips screw driver a small pair of needle nose pliers and a 2” x 8” x 8” block of some type.
6. 6.1 INSTALLATION TOOLS AND EQUIPMENT NEEDED • Screwdriver and Mounting Screws: The only tool needed to install the DPT 115 is a screwdriver for securing the pan & tilt base to its mount. • #2 Phillips Screwdriver: To be used if access into the Electronics module is required. • Customer furnished video cable from pan & tilt head to the user monitor. 6.2 STANDARD INSTALLATION To get optimum performance from any pan and tilt it is important to have the weight of the camera and lens balanced.

6.3 DPT 115 FOOTPRINT DRAWING The required hole pattern for securing the pan & tilt head to a mounting surface is a symmetrical two-inch by five-inch pattern. Four (4) mounting screws are needed to mount the pan & tilt head. Care is to be taken to mount the pan & tilt in the proper orientation. Note the location of the connector plate on the base of the pan & tilt head. This surface is the rear of the pan & tilt assembly.
6.4 MOUNTING TELECONFERENCING LENS ADAPTER Mount adapter bracket as shown to camera and lens assembly using ¼-20 screw and appropriate flat and lock washers. Using this bracket allows the camera and lens assembly to be mounted on the pan and tilt with the balance point of the weight centrally aligned to the tilt pivot point of the pan and tilt head.
6.5 BALANCING CAMERA AND LENS 1. Place the camera/lens/adapter plate on a flat surface. Place a pencil or other small round cylindrical item under the teleconferencing lens adapter plate as shown. 2. Move the camera/lens/adapter plate laterally, both left and right to determine the balance point of the assembly. This the point at which the assembly would rock easily on the pencil resembling a seesaw for children. 3.
5. Place the camera/lens/adapter plate on the pan and tilt as shown below. Position camera/lens/adapter plate assembly such that balance point is located directly over center point of the tilt axis of the pan and tilt head. Install mounting screw and washers at this time, Do not tighten. 6. Move the camera/lens/adapter plate assembly to the right (forward) approximately 1/8 inch. The mounting screw should be tightened at this point. Remove the tape marking the pivot point at this time.
6.6 INVERTED INSTALLATION The pan and tilt unit may be inverted or hung in certain applications. The teleconferencing lens adapter bracket is required to provide the necessary clearance between the lens and the side of the pan and tilt. If the unit is hung the pan left, pan right, tilt up, and tilt down functions will be backwards for that particular camera station. This condition can be corrected by reversing the manual controls to the pan and tilt for this particular camera.
