Moog Pan and Tilt Control Circuit Board Description
Power and communication to control the P&T is provided through the 53-Pin base
connector. The Moog Pan & Tilt microprocessor / circuit control board processes all
communication, position information, and presents it through the communication
buss via the Protocol. The system may be controlled either by a serial or IP
connection.
CAUTION
DO NOT CONNECT TO VOLTAGES HIGHER
THAN 28 VDC WITHOUT RECONFIGURING.
Power supplied is a minimum 24 VDC providing power to the Control Circuit Board
to control the two (2) stepper motors drivers (1 for Pan Axis and 1 for Tilt Axis), as
well as regulated and unregulated power to the side mounted payload ports. Note
the Positioner may be supplied higher voltages for extended performance if
configured to do so on the Control Circuit Board. DO NOT APPLY MORE THAN 28
VDC to the unit without first configuring the PCB to accept higher voltage.
The Control communication is processed on the control circuit board providing
control and status information on the communication buss. Also connected to main
controller are two incremental position encoders, an optical encoder is used of the
Pan Axis motion and a magnetic encoder is used for the Tilt Axis motion.
The Control Circuit Board is attached vertically to the inside of the Pan & Tilt Housing
and can be accessed by removing the Rear Access Cover. The Control Circuit Board
must be accessed to configure P&T input voltage selection, voltage selection and
method of communication to the payload ports.
The Control Circuit Board has a number of switches and jumpers to allow various
configurations of power and communication options. The following section outlines
PCB configuration to allow various configurations.

Circuit Card Access
1.
Remove the sixteen 5/16” hex head bolts holding the rear cover. Place the
cover aside, assuring not to damage the O-Ring gasket, mating surface or
paint. Locate the Ethernet cable on the left side of the board and release the
cable from the connector port. Refer to Figure 6.
