Specifications

The PT-101 is shipped in standard RS-485 mode; with all of the jumpers UP.
Switch all three of the jumpers to the lower position, and the head is now configured for RS-232
mode. The same control codes used for RS-485 apply for moving the head using Eagle™ soft-
ware or when writing your own software. These control codes are available off of the Eagle
website, http://www.eaglepantilt.com. Please be aware that the maximum reliable distance for RS-
232 control is only about 50 to 75 feet, and that only one PT-101 head may be hooked up per
serial port as is standard with RS-232 communications.
ENERGIZING THE SYSTEM
Power up the Eagle™ pan tilt controller before powering up the PT-101 pan tilt head. When this is
done, you may now power up the power supply for the PT-101 head(s). Observe the red status
LED lens on the front of the pan tilt head. About two seconds after power is applied, the LED
should blink twice. This is to signal that the main microprocessor is active, and ready to receive a
command. The head will automatically travel to it’s “home” position of straight ahead and level.
During this travel period, remote control is not possible. This home position is not able to be
changed, and the head must home itself whenever power is applied. If the head does not go to the
home position, it will not function; please call for service.
The LED provides important visual feedback to the status of the head; if the head has been acti-
vated and is being talked to by a controller, the LED is on solid, with some flickering. If the head is
attached to the RS-485 line and hearing a command being sent to another head, it will flicker.
If the LED comes on solid, with no flickering at all, it usually means the RS-485 wiring is incorrect.
Usually the ground and one of the data lines have been swapped. Check the wiring and try again.
PAN-TILT OPERATIONS
Be sure to follow all of the installation and safety instructions included with the Eagle™ PT-
101 pan tilt head before starting to use this system !!
First, select the address of the head you wish to control. Since up to 31 Eagle™ heads may be on
a single RS-485 line, you must choose the correct one to control (only 8 may be controlled from
the PT-C-50 controller). Select CAMERA, then the number of the head to be controlled. Head
addresses can be changed as described in the previous section about addressing on page 9.
If this is the first use of the system, the limits of pan tilt movement should be adjusted as desired
now. Begin by entering the proper command on your controller to clear all movement limits. This
function will eliminate all safety limits that have been set at the factory to prevent excess travel.
This clearing is temporary only; when power is cycled off and on, the previous limits will return
unless you have set new limits. This will erase any limits previously set by the factory during test-
ing.
Now, set the safety limits of travel as desired. Use the LIMIT then UP, DOWN, RIGHT, and LEFT
for up, down, left, and right limit setting. Remember, that the pan tilt head has a range of pan of
