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 Receivers 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 auxiliarys 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.
