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 sta-
tus 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 feed back to the status of the head; if the head has been acti-
vated and is being talked to by a con trol ler, the LED is on solid, with some fl ickering. If the head is
attached to the RS-485 line and hearing a command being sent to an oth er head, it will fl icker.
If the LED comes on solid, with no fl ickering 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 con-
trolled from the PT-C-55 controller). Select CAM ERA, then the num ber of the head to be con-
trolled. Head ad dress es can be changed as de scribed in the previous section about ad dress ing.
If this is the fi rst use of the system, the limits of pan tilt movement can be adjusted as desired
now. Begin by entering LIMIT, MENU to clear all movement limits. This function will elim i nate all
safety limits that have been set at the factory to prevent ex cess travel. This clear ing is tem po rary
only; when power is cycled off and on, the previous limits will return unless
you have set new
limits. This will erase any limits pre vi ous ly set by the factory dur ing initialization.
Now, change the safety limits of travel if desired. Use the LIMIT then UP, DOWN, RIGHT, and
LEFT for up, down, left, and right limit set ting. Re mem ber, that the pan tilt head has a range of
pan of 360° (left or right 180°), and a tilt range of 90° (up or down 45°); it cannot turn more
than a full circle. There are end travel stops programmed into the head at the factory to pre vent
traveling more than these amounts; these can not be cleared when clearing the safety limits. Once
the travel limits are set, normal usage of the pan tilt system may be gin.
The PT-101 head uses DC stepper type motors instead of geared motors. If an obstruction is
encountered during travel, the motor merely “slips” until the condition is corrected. This prevents
damage to both the pan tilt head and the camera/lens. If this oc curs, re called preset po si tions will
not be re called cor rect ly until the next time the PT-101 head passes through the “home” position
of straight ahead and level.
