The ST-PTZMINI-KB’s RS485 interface and power connection share a common
cable connected directly to the unit as depicted below. A terminal block for wiring
UTP (unshielded twisted pair) cable between the PTZ camera or other device and
the controller is included.
b. Connect the 12VDC 2A power supply to the ST-PTZMINI-KB’s female power
connector.
c. Using UTP cable connect the ST-PTZMINI-KB’s RS485 port to the PTZ camera’s
RS485 port. Using the terminal block be sure the polarities are correct and consistent
with the camera. Always consult the camera’s manual regarding PTZ controller
connections.
d. Connect power supply’s AC plug to a suitable AC power outlet. When power is applied
the ST-PTZMINI-KB will automatically display the baud rate and keyboard protocol on
the LCD screen. Note: When the controller is initializing the joystick should be in the
“nil” (0 or neutral) position.
e. It is also possible for the ST-PTZMINI-KB to control multiple PTZ cameras using a
matrix switch in lieu of a DVR per the diagram below. The PTZ controller and cameras
are connected in parallel to the matrix’s RS485 buss. Be sure to assign each camera
a unique address and set the cameras’ and controller’s communications at 9600bps.
