INSTALLATION & INITIAL SETUP
3.5 Initial Power-up and Test
If you have the power source and Host computer connected described in Sections 3.3 and 3.4,
you are ready to power-up and test its operation. Test and verify all cable connections and
connector wiring before power-up. We suggest that you do not mount your payload (e.g., camera)
until this initial installation is completed and tested.
1. Using HyperTerminal or a similar terminal program, configure the RS-232/485 serial port of
the Host Computer to 9600 baud, 1 start bit, 8 data bits, 1 stop bit, and no parity. Hardware
handshaking and XON/XOFF are not used.
2. You are now ready to power up the pan-tilt unit and test its operation. Apply power. Upon
power up, introduction text should appear on your screen, and the pan-tilt unit should go
through a reset cycle (pan and tilt axes will cycle through their full range of motion). This
reset is completed when an asterisk ('*') appears. If the unit did not reset properly, recheck
your power source and cabling. If the unit went through its reset procedure, but no text or
garbled text appears on your screen, then:
•
Check that the host RS-232/RS-485 host port settings are correct (see Section 3.4)
•
Check that the RS-232/RS-485 cable is correct for your host (see Section 3.4)
3. You are now connected to the pan-tilt. Enter the character '?' for a complete listing of
commands. The next section describes some basic commands to help you get going, and a
full command description may be found in Section 4. We suggest that you exercise the unit
and become familiar with its operation and commands before mounting your payload (e.g.,
camera) as described in Section 3.8. Special attention should be paid to acceleration and
speed commands, and they should be set at levels appropriate to your payload weight and
size.
3.6 Basic Pan-Tilt Unit Commands
Below are some pan-tilt commands that will familiarize you with the pan-tilt unit and its
operation:
pp2500 *
tp-900 *
PS1900 *
pp0 *
This sets the pan axis to position 2500, the tilt axis to position -900, the pan speed to 2500
positions a second, and sets the pan position back home.
When operating the pan-tilt unit, the available command menu is printed when you enter the
'?' character. A detailed description of pan-tilt commands and queries may be found in Section 4.
3.7 Mounting Your Payload
The PTU-D300 sports a flexible payload bracket system that can be configured in a number
of ways to support a variety of payloads including cameras, lasers, antennas, and other equipment.
Because of the heavy payload weights and high potential speeds supported by the PTU-D300, it is
very important that all guidance and instructions regarding payload mounting be followed
carefully.
