Installation Manual Pyramid DC Receiver

THE DC RECEIVER

The Pyramid DC Receiver is a variable speed pan and tilt control receiver that can be connected to any camera within the

Pyramid system that has a DC 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 drives the Pan/Tilt head at variable speed by using the

PWM (Pulse Width Modulation) of the 24V DC supply to the head. The DC receiver can also drive zoom and focus

functions, and the four auxiliary functions (wipers, lights etc.) that can be connected via the four auxiliary relays on the

receiver PCB.

The DC receiver can be programmed remotely with privacy zones, limit stops, random patrols, and up to 128 presets. It

also contains a video amplifier, with gain and high-frequency lift. This can improve video transmission over longer cable

runs.

Figure 1 - DC Receiver Layout (Weatherproof Box Variants)

There are six variants of the DC receiver, which can be split into two groupsthe three variants that are supplied in a

weatherproof box (PY-DCW-) and the three variants that are supplied as a PCB only (PY-DCB-). In each of these two

groups, the difference between the three variants is based on the network speed and the type of network card fitted.

The -L variants (PY-DCW-L and PY-DCB-L) run on a low speed (9.8k b.p.s.) RS485 network while the -HR variants (PY-

DCW-HR and PY-DCB-HR) run on a high 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 configured 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 changed using the switch settings. For more details on the PY-COM network card, see page 12.

The -H variants (PY-DCW-H and PY-DCB-H) are fitted with a PY-FTT network card and run on a high speed (78k b.p.s.)

FTT10 network.
