CONNECTING THE PAN/TILT HEAD AND AUXILIARIES POWER SOURCE
CON5 accepts the AC power input which is then switched to CON4. It powers the Pan/Tilt head and auxiliaries. CON5 can
be connected to either a 24V AC or Mains power supply.
For Mains Connections
Referring to Figure 7, connect CON5 to the LIVE and NEUTRAL connections on the external terminal block. The connections
should be made to the non-fused side of the terminal block. The centre connection on CON5 is not connected.

Figure 7 - Connecting CON5 to a Mains Power Supply
For 24V AC Connections
Connect the 24V AC power supply to the LIVE and NEUTRAL terminals on CON5 (see Figure 7 above). The centre
terminal on CON5 is Not Connected (NC).
WARNING
Never use both 24V AC and Mains on the same receiver PCB.
ANTI-TAMPER CONNECTIONS
CON6 is used as an input for an external anti-tamper switch. It is connected in parallel with the built in anti-tamper switch
that is marked in Figure 2.
On the boxed variants, the built in anti-tamper switch is connected in a normally open (N/O) configuration. However, it is
fitted with a spring which is compressed when the module lid is closed, and thus closing the contact. When the lid is
removed, the input is opened and the alarm will be activated.
If the built in anti-tamper switch is not used, CON6 can be connected to an external anti-tamper switch. To do this, the
spring must be removed from the built in anti-tamper switch. CON6 should then be connected to the external anti-tamper
switch in a normally closed (N/C) configuration.
VIDEO CONNECTIONS
All video must be connected to the receiver PCB via 75 ohm BNC connectors and video coaxial cable. Referring to Figure
2, connect the video from your camera to VIDEO IN and connect VIDEO OUT to the matrix.
Your AC receiver has an on-board video amplifier with gain and lift. Adjustment of gain and lift is done remotely, using a
Pyramid keyboard. For more details on adjusting gain and lift levels, consult the Pyramid 2 Keyboard Operating Manual.
