Product Description
The new videotronic variable high speed pan/tilt motor is a breakthrough compared to
conventional pan/ tilt motors available to date. It combines elegant design with excellent
and outstanding performance. Among individual and customised programs and control
functions you have very accurate panorama steering (pre-set tour through up to 100
different pre-programmed positions) with variable speed adjustment of up to 90°/sec.
during pre-set call with a backlash of < 0.1°. The motor is using high precision stepper
motors and self-locking worm gears, resistant to wear. Due to self-lubricating gears the
unit is suitable for continuous operation. Regular service and/ or maintenance are not
necessary.
The integrated RS-232 serial interface allows the unit to be adapted to any existing or
future telemetry system. The integrated RS-485 control circuit board makes the motor
fully compatible with the Videotronic BUSTRONICRS-485 network. In combination
with the Videotronic HQ System Camera (colour, mono or colour/mono) the variable
speed is automatically controlled in relation to the zoom position (wide/ tele). This
package embodies the most elegant and sophisticated PTZ camera unit available on
the market.

Connecting the Video Signal (F)BAS, Twisted Pair, Y/C Operation
If the pan/tilt motor is being used with a colour camera, the video signal can be
transmitted via standard coaxial cable (FBAS), S-VHS cable (Y/C operation) or twisted
pair cable. If you are using a b/w camera, only coaxial and twisted pair connections are
possible.
For service purposes, the video signal can be tested on a service monitor using the test
socket (video test) on the circuit board. This option allows easy adjustment of all camera
stations directly on site.

(F)BAS Operation
For standard transmission over coaxial cable connect the cable to the terminal block
„Video Out“ (FBAS/GND) inside the service junction box. The shield of the coaxial cable
has to be fixed with the strain relief clamp.
Set the FBAS / Y jumpers as shown in the drawing!
Y/C - Operation
With a separated transmission of brightness and colour information (Y/C), the quality of
the signal can be considerably improved. The shields of the corresponding cable have
to be fixed with the strain relief clamp..
Set the FBAS / Y jumpers as shown in the drawing!

MOUNTING AND CONNECTING

Twisted Pair Video Transmission
Transmission of the video signal via standard telephone cable is useful where you have
existing telephone cable. This will significantly reduce your costs compared to additional
coaxial connections. Via twisted pair you can achieve transmission distances of up to
1.500 metres. Inside the service junction box of the P/T head you need an additional
plug-in circuit board (PL-VZS) to convert the signal to twisted pair. Connect the
telephone cable to the „Video Out“ terminal block (FBAS = signal A and C = signal B) as
shown in the drawing.
Remove the FBAS / Y jumpers as shown in the drawing.

MOUNTING AND CONNECTING

Connecting the operating voltage 230 V AC / 50 Hz
Connect the power cord to the terminal block „Operating Voltage“ inside the service
junction box. The camera station has a primary fuse (2 AT). The secondary fuse has a
value of 3.15 AT. Should it be necessary to replace the fuses, please make sure to use
the designated values.
Attention: Do not yet turn the operating voltage on.
(please see: Commissioning first)
Connecting the interface RS-485 / RS-232
The interface cable (RS232 / RS485) has to be connected to the terminal block „Input
Interface“.
RS-485 A Signal A
B Signal B
RS-232 CTS Clear to Send
RTS Ready to Send
TxD Transmit Data
RxD Receive Data
Please note that you can only use one control interface at a time. When installing the
device, you have to determine either of these interfaces (see Configuration Camera
Station). The unit is factory set to RS-485. You can connect a KB-485 keyboard to the
„KB-485“ socket for test purposes. This option allows you to control all camera functions
directly on site. If the P/T unit is the first or last device within the RS-485 BUS, it has to
be terminated using a 120 Ohm termination resistor (jumper RS485) inside the service
junction box. All further stations within the BUS must not be terminated (remove
jumper). If the P/T unit is controlled via RS-232, please refer to the RS-232 protocol
attached to these instructions.

Commissioning
When you turn on the operating voltage (230 V/AC), the unit automatically starts a self
test routine to check the horizontal and vertical limit switches and the motorzoom lens.
When the self test has been completed, the unit is fully operational and can be
controlled via the configured interface.
Configuration of vertical axle
Depending on the position in which the compact camera has been installed to the motor
bracket, it could be possible that the up and down function needs to be swapped. In this
case, please enter ^G at the KB-485 keyboard.
Correlation of speed
The variable speed of the motor is controlled by the focal length position of the
motorzoom lens to male sure the motor moves quickly in the wide angle mode and
slowly in the tele mode. If you wish the correlation to be inverted for your individual
purposes, enter ^C at the KB-485 keyboard.

MOUNTING AND CONNECTING

Setting the horizontal and vertical limit switches
The factory adjustment of the limit switches ensures that motor can only be moved in a
relatively small range to avoid damage during installation caused by blind obstacles.
After you have connected the operating voltage for the first time, the unit checks the
limit switches and stores them into the internal memory. Now you can start to adjust the
limit switches to your individual requirements. Please proceed as follows:
•turn home position and panorama function off
•open the motor at the lateral parts as shown above
•loosen the stud screws of the corresponding axle
- adjustment of vertical limit switches ±60°
- adjustment of horizontal limit switches ±175°
•go to the desired limit switch position using the test sockets
•fix the stud screw of the adjusted axle
•to switch to the other axle, hit both test sockets simultaneously
•repeat the above procedure to adjust the second axle
•hit both test sockets for at least 1,1 seconds to activate a RESET
N.B.: After adjustment of the limit switches, you must run a RESET to store the
changes in the internal memory of the unit!
A RESET can also be activated from the KB-485 keyboard. Enter ^ and
the right F key or cut off the voltage.
Caution!
After pressing the keys on the circuit board a reset has to be carried out
