THE AC RECEIVER
The Pyramid AC Receiver is a fixed speed pan and tilt control receiver that can be connected to any camera within the
Pyramid system that has an AC Pan/Tilt head. The receiver is easy to install, and a service pin and test button are included
to aid the installation process. Once it has been fitted, the receiver will drive the pan, tilt, zoom and focus functions of a
Pan/Tilt head, and it can also drive auxiliary equipment (wipers, li hts etc.) throu h the four auxiliary relays on the receiver
PCB.
The AC receiver can be pro rammed remotely with privacy zones, limit stops, random patrols, and up to 128 presets. It
also contains a video amplifier, with ain and hi h-frequency lift. This can improve video transmission over lon er cable
runs.

Figure 1 - AC Receiver Layout (Weatherproof Box Variants)
There are six variants of the AC receiver, which can be split into two roupsthe three variants that are supplied in a
weatherproof box (PY-ACW-) and the three variants that are supplied as a PCB only (PY-ACB-). In each of these two
roups, the difference between the three variants is based on the network speed and the type of network card fitted.
The -L variants (PY-ACW-L and PY-ACB-L) run on a low speed (9.8k b.p.s.) RS485 network while the -HR variants (PY-
ACW-HR and PY-ACB-HR) run on a hi h speed (78k b.p.s.) RS485 network. Both the -L and -HR variants are fitted with
a PY-COM network carda combined personality network card which can be confi ured by means of dip switches for use
in RS485 or RS422 networks. By default, the switches are set so that the card operates in RS485 protocol, but the card
protocol can be easily chan ed usin the switch settin s. For more details on the PY-COM network card, see pa e 12.
The -H variants (PY-ACW-H and PY-ACB-H) are fitted with a PY-FTT network card and run on a hi h speed (78k b.p.s.)
FTT10 network. For more details on the PY-FTT network card, see pa e 11.

PCB POWER CONNECTIONS
CON1 is used for PCB power connection. This power controls the switchin of the relays, the video ain and lift and the
lens functions. The AC power for the Pan/Tilt head and auxiliaries is connected separately to CON5.
The PCB requires a +12V DC, 1A class 2 power supply. The necessary connections have already been made on the
boxed variants, includin a roundin wire which is connected from the ne ative terminal of CON1 to the external terminal
block (Fi ure 3). On PCB versions, connect the 12V DC as shown in Fi ure 3.

CONNECTING THE PRESET FEEDBACK POTENTIOMETERS
If you are usin a preset Pan/Tilt head and lens, then CON2 provides the supplies and feedback connections for the
potentiometer wiper circuits. The direction of the feedback is automatically calculated when the test routine is invoked
(see Testing on pa e 18), this means it is not necessary to wire the pots in a specific direction.
Referrin to Fi ure 4, connect CON2 to the preset pots on the Pan/Tilt head and the lens. Connect any unused feedback
inputs to round. Make a note on your module description sheet of the preset connections and the type of lens.

Connect the 24V AC power supply to the LIVE and NEUTRAL terminals on CON5 (see Fi ure 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 Fi ure 2.
On the boxed variants, the built in anti-tamper switch is connected in a normally open (N/O) confi uration. However, it is
fitted with a sprin which is compressed when the module lid is closed, and thus closin 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
sprin 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) confi uration.
VIDEO CONNECTIONS
All video must be connected to the receiver PCB via 75 ohm BNC connectors and video coaxial cable. Referrin to Fi ure
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 ain and lift. Adjustment of ain and lift is done remotely, usin a
Pyramid keyboard. For more details on adjustin ain and lift levels, consult the Pyramid 2 Keyboard Operating Manual.
