INSTALLATION & INITIAL SETUP PTU-D300 User’s Manual (v2.18.0)

The easiest way to wire into the D300 is to use the DP factory cable with breakouts for power

and other connections (model D300AC-CAB-25BO), and to use the DP factory power supply

(model D300AC-APS-30V). This allows you to plug in and run the D300 in minutes. Or you can

use the wiring diagram in Appendix A.3 to make your own cables that better suit your installation.

Connect an RS-232 or RS-485 cable between the D300 and a host computer. When using the

factory cable D300AC-CAB-25BO, standard RS232 connection (DB9F) is provided.

HyperTerminal (built into Windows) is the most commonly used communications program.

Communications parameters are: 9600 baud, no parity, no handshaking. (see Section 3.4).

The D300 provides payload pass-thru signals that connect between pins in the base

connector to corresponding pins in the payload connector. Additional pins in the payload

connector provide other payload controls (auxiliary RS232 ports and TTL control). Figure 2

shows this payload connector which is also a MIL-C-26482 compatible receptacle (19 pins).

Appendix A.4 details the payload connector pin-out.

Appendix A.4 shows the payload connector wiring. Pins highlighted in red indicate payload

pass-thru signals connected to corresponding pins in the base connector.

When attaching payload signals to the system, care must be taken to adhere to all

specifications for the pass-thru signals, such as maximum voltage and current

levels.

3.3 Power Sources

The PTU-D300 requires a 9-30VDC (unregulated) power source capable of 2.25A peak. Less

peak current is required if you do not use the higher motor current controls available (see Sections

4.6.1 and 4.6.2). To achieve the highest pan-tilt unit performance, use the highest motor voltage

within the allowable range. To achieve the quietest and smoothest pan-tilt operation, you can use

a lower motor voltage (e.g., 12VDC).

When wiring your own power source, failure to comply with wiring and power source

requirements described in this manual can result in decreased unit

performance or damage not covered under the limited warranty.

If you are providing your own DC power source, the power source must never supply

more than rated current, and if so, you must add a fuse in series with your DC power

source. For example, when connecting to a vehicle battery or lighter plug, you must fuse the

incoming DC source. Failure to properly fuse your input power source could cause overloading of

internal protection devices, pose a safety hazard, or void product warranties.
