Pyramid DC Receiver Installation and Operating Instructions
PRODUCT SAFETY
Please follow these instructions as you install your pyramid module and keep them for future use. If you have any
problems contact your Baxall agent.
WARNING
Installation is only to be carried out by competent, qualified and experienced personnel. Wire in accordance with
your national wiring regulations. Failure to do so can result in injury or death by electric shock. Use a class 2 isolated
power supply for the 12V DC.
PRODUCT RELIABILITY
CAUTION
Your module is susceptible to damage from Electrostatic Discharge (ESD). Take normal ESD precautions when
handling your network card. ESD prevention kits are available from most electronics distributors.
Do not exceed the voltage and temperature limits given in the specification.
Switch off the power before fitting a network card.
ELECTROMAGNETIC COMPATIBILITY (EMC)
CAUTION
This is a Class A product. In a domestic environment this product may cause radio interference in which case the
user may be required to take adequate measures.
This product is intended for use in general purpose CCTV applications in a residential, commercial or light industrial
EMC environment, refer to Baxall Limited before using the product in an industrial EMC environment.
The product must be installed in accordance with good installation practice for EMC to enable the product to function as
intended and to prevent EMC problems.
Contact the Baxall Technical Support Department to obtain a specification defining the acceptable levels of product
degradation with regard to EMC immunity.
MANUFACTURERS DECLARATION OF CONFORMANCE
The manufacturer declares that the equipment supplied with this manual is compliant with the essential protection
requirements of the EMC directive 89/336 and the Low Voltage Directive LVD 73/23 EEC. Conforming to the requirements
of standards EN 55022 for emissions, IEC801 parts 2, 3 and 4 for immunity and EN 60950 for Electrical Equipment
safety.
UNPACKING
Keep your packaging for use if your DC receiver is stored for a time or needs to be returned for whatever reason. The
packaging should contain:-
 PY-DCW, DC receiver
 An A4 Module Description Sheet (for installation details)
 These Instructions
 Two identical bar-codes
Check the product code on the serial number label. If you have an incorrect item or it is damaged then inform the
suppliers and carriers immediately. If this is the case then do not attempt to use your DC receiver.

Installation and Operating Instructions Pyramid DC Receiver
THESE INSTRUCTIONS
These instructions allow you to install your Pyramid DC receiver, they do not contain any application information. As the
installer you are assumed to have a sound knowledge of how receivers operate, if you have not then contact a CCTV
installation company for advice.
If you are replacing a receiver on a network which is already operational then see Manual 1 - Operating Instructions for
instructions on connecting a new receiver using the keyboard.
The connection diagram is shown in Figure 1. Using this, follow the instructions. The instructions are listed by connector
and describe wiring your DC receiver to the P/T head, the lens, the network and the power supply.
At the end of the connections section is a description of the on-board test routine. Once the tests are complete and all the
connections are correct, your DC receiver needs no maintenance.
To vary the speed of your Pan/Tilt head, the Pyramid DC receiver uses PWM (Pulse Width Modulation) of the 24V DC
supply to the head. Check that your DC Pan/Tilt head operates by the same method.
BAR CODING
All the Pyramid modules are supplied with two identical bar-codes, remove one and affix it to the module description
sheet, remove the other and affix it to the module.
The bar code gives the unique 48-bit module address. Make a careful note on your module description sheet of all your
installation details and the location of the module. Then during subsequent installations using the Windows installation
tool, the module address can be entered with the description.
We recommend that during a system installation you store the module description sheets in a ring-bound file and keep
them for reference after the installation is complete.

Pyramid DC Receiver Installation and Operating Instructions
CONNECTIONS
Below is a description of each of the connectors. The connections are described in numeric order, followed by video,
network and power connections.
CON1
CON1 is for the 24V DC power connection. Your DC receiver requires a +24V DC, 65W class 2 power supply, this is
already connected. If the polarity is correct when the power is switched on, LED1 (see figure 1) will illuminate green. If the
polarity is incorrect, it will illuminate red.
CON2
If you are using a preset P/T head CON2 provides the supplies and feedback connections for the potentiometer wiper
circuits. The direction of the DC feedback circuits are automatically calculated when the test routine is invoked by running
the Pyramid DC Receivers test routine. This means it is not necessary to wire the pots in a specific direction.
Referring to figure 1, connect CON2 to the preset pots on the P/T head and the lens. Connect any unused feedback inputs
to ground. Make a note on your module description sheet of the preset connections and the type of lens.
CON3
CON3 provides the lens drive outputs for focus, iris and zoom. The drive voltage is +12V DC, maximum 100 mA. Refer to
your lens instructions and connect up your lens according to figure 1.
CON6
CON6 is provided for the connection of an external anti-tamper switch. It is connected in parallel with the built-in anti-
tamper switch shown in figure 1. The built-in anti-tamper switch has an actuation spring fitted which must be removed if
you are using an external anti-tamper switch connected to CON 6. The switch must be a normally closed (N.C.) type.
CON9
CON9 accepts the power input which is switched to CON10 and CON11 for powering the auxiliaries. Maximum per
auxiliary, 2A at 240VAC.
Referring to figure 1 connect CON9 to your auxiliarys power supply. The middle connection on CON9 is Not Connected
CAUTION
Connect lamps using a separate relay as they draw an initial surge current which may damage your DC receiver.
Always provide a separately fused mains spur for use with auxilliary devices.
CON10 and CON11
Referring to figure 1, connect Auxilliaries A to D as shown to CON10 and CON11. Each application must not draw more
than 2A at 240V AC. Connect the return wires together on a spare terminal on the external terminal block. From there
connect them back to CON9.
CON13
CON13 provides the power output connections for your P/T head. Referring to figure 1, connect your P/T head to CON13.
CAUTION
Your application must not draw more than 1A per drive output and 0.25A per brake output or it will damage your DC
receiver.
VIDEO
All video must be via 75 ohm BNC connectors and video coaxial cable. Your DC receiver has an on-board video amplifier
with gain and lift. Adjustment of gain and lift is done remotely, via the network. Referring to figure 1, connect the video from
your camera to VIDEO IN, through your DC receiver, then from VIDEO OUT to the matrix.

CONNECTIONS
NETWORK
Network cards come pre-fitted to your Pyramid DC Receiver and in normal circumstances there will be no need to disconect the network
card. If you need to remove or refit a network card, proceed as follows.
CAUTIO
N
To avoid damaging your module switch off the power before fitting the network card
Switch off the power, fit a network card in the position indicated on figure 1. Connection details for the network card are
included on the sheet provided with the network card.
POWER CONECTIONS
WARNING
Ensure that the power is switched off before connecting the mains wires.
Your PY-DCW module must be earthed.
If you are using mains, connect the Live, Earth and Neutral wires from the mains supply to Live, Earth and Neutral on the
terminal block fitted to the baseplate.
Check that all the wiring is correct and switch on the 24V DC power and the power supply for your auxiliaries.
WARNING
YOUR DC RECEIVER PCB MAY NOW CONTAIN LIVE VOLTAGES
TESTING
Your DC receiver has an on board test procedure which steps through the outputs in the sequence shown in table 1. The
test push button is shown in figure 1. The test takes 55 seconds.
WARNING
YOUR DC RECEIVER PCB CONTAINS LIVE VOLTAGES
CAUTIO
N
Ensure that the mechanical endstops are set before running the test routine. This will prevent the P/T head crashing.
Press the test push button with an appropriate tool
