-
Supply voltage - 12 V nominal - (10.2 to 13.8 V - automotive).
-
Motor current - 1.9 A nominal, 2 A max.
-
Forward and reverse control using two joysticks. The control is open-loop - i.e. speed, but we can be adapted for "torque-type" of control using the motor current. Position control is also a possibility using a shaft encoder fitted to the servo motors.
-
Left joystick - tilt (up and down), right joystick pan (left to right).
-
Joystick factory calibration to set up the maximum and the minimum - in calibration mode.
-
Joystick to be contactless type with return to centre spring positioning, protective boot and round knob.
-
Joysticks used are two axis type with only one axis used for the control, the other axis is not used.
-
The enclosure is Satin-Black powder-coated mild steel with rounded corners and suitable front panel decal. Size - 310 x 170 x 50 mm (width x height x thickness), excluding additional dimension required by joysticks, potentiometer controls and connectors.
-
All cable connections at top of enclosure except power in which is at the bottom.
-
Camera Head connector (6 pin female - type Neutrik 6 Pin Chassis Female, NC-6/FP-1. Pin 1 - Pan Motor +ve, pin 2 - Pan Motor -ve, pins 3 & 4 - not used, pin 5 - Tilt Motor -ve, pin 6 - Tilt Motor +ve) to be used for power control to each motor. A six core cable (>1mm2 conductors) will be required to connect to the Camera Head.
-
+12 VDC power in connector (4 pin male - type Neutrik Chassis Male, NC-4/MP) to be on right hand side bottom to suit belt fitting battery pack. Pin 1 - 0 Vin, pin 4 - +12 VDC in, pin 2 - RS232 TX and pin 3 - RS232 RX.
-
ON/OFF rocker switch at top right of enclosure with power on green LED on the front panel will indicate that the unit is ON.
-
Potentiometer adjustments with graduations for:
Maximum motor speed (motor current).
Ramping rate (maximum acceleration).
Joystick deadband adjustment.
-
Separate adjustment controls for each joystick.
-
16:9 format LCD screen video monitor.
-
Clear polycarbonate window for protection and sealing of LCD screen.
-
Input for LCD screen is standard video input - PAL compatible.
-
BNC connector provided for video input from the camera.
-
A BNC connector also provided for video output to a reference monitor which is buffered/amplified to ensure 75 Ω impedance matching and correct signal levels (1 Vpk-pk).
