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.

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.

PY-COM NETWORK CARDS
If a PY-COM network card is fitted to the AC receiver, it can be confi ured by means of dip switches for use in both RS485
and RS422 networks. The dip switches for the different network types are shown below:
RS485 Mode
RS485 networks are 2-wire, bus-connected (also referred to as daisy-chain). In RS485 mode, the dip-switches on the
PY-COM will be set differently dependin on where the unit is placed on the network. If the unit is the first or last in the
network, one network card in the unit will need to be set to provide biasin and termination as required. If the unit is central
to the network, all network cards will be set for use in a intermediate module.
Set the switches as required and wire the card to the network as shown in Fi ure 11. It is not necessary to make any

ADDRESSING A RECEIVER WITH THE PYRAMID 2 KEYBOARD
Each receiver that is connected to the Pyramid system must have a unique address called a network address, and an
operator with installer privile es can do this usin the Pyramid 2 Keyboard.
Confi uration of the receiver requires the service button to be pressed on the receiver PCB, and this may be a two man
operation if the receiver is located remotely from the keyboard. For this reason, it is easier to address a receiver before it
is added to the network, and this can be done usin a special mode of the Pyramid keyboard called Self-Bind (also known
as Fn 100). Self-bindin mode is commonly used when confi urin telemetry receivers, or when cameras need to be
controlled in a system without a CCTV matrix.
Durin the self-bindin process, the installer can setup the network address, which includes the node IDthe number
that is entered to indicate which device is to be controlled (e. ., Camera receiver number 4). Once the network address
has been confi ured, the receiver can be attached to the network and controlled throu h the Pyramid matrix.
To address a receiver in self-bindin mode, follow the steps below:
1. Connect up a Pyramid 2 Keyboard to the telemetry receiver. This can either be connected directly to the receive
communications card at the receiver site, or remotely throu h the Pyramid network in the normal way.
2. Lo onto the Pyramid 2 Keyboard usin the installer password. The Installer Logon screen is displayed.
3. Press the Function 100 soft-key. The Direct Access screen is displayed.
4. Press the Receiver soft-key.
5. Press the Rx Utilities screen key.
6. Press the Unit Address Type soft-key.
The Addressing screen is displayed.
7. Press the Receiver Address soft-key. The keyboard LCD displays a messa e askin the operator to press the
service pin.

8. So that the keyboard can identify the receiver, press its service pin. On the AC receiver, the service pin is located on the
PCB as two pins to be shorted (see Fi ure 2).
When the service pin is pressed, the receivers neuron ID is transmitted to all other devices on the Pyramid network.
The neuron ID is a unique identifier which is used to establish communication between the receiver and all other
devices. Once the receiver has been identified by the network, it can be assi ned a node ID.
9. The keyboard LCD displays a messa e askin the operator to enter the new node ID. The node ID is the visible part
of a network address, as it is the number that an operator enters on a keyboard to indicate the device that is to be
controlled (e. ., Camera receiver number 3).
Use the number keys to enter the node ID.
10. Press the Receiver Address soft-key a ain to confirm the node ID.
The keyboard LCD displays a messa e confirmin the address.

ADDRESSING A RECEIVER WITH THE MK1 KEYBOARD
A receiver can also be addressed usin the Pyramid Mk1 Keyboard. Follow the steps below:
1. Connect up a Pyramid Mk 1 Keyboard to the telemetry receiver. This can either be connected directly to the receive
communications card at the receiver site, or remotely throu h the Pyramid network in the normal way.
2. Usin the keyboard, insert the Installers Card and lo on with the PIN number 1892.
3. Press the key sequence 100 and then the Function key.
The left hand side of the keyboard display will show Fn 0100 to indicate that self bindin mode has been invoked.
4. Repeatedly press the List Down key, until the LCD display shows the option Replace RX.
5. Once this option is displayed, select soft key number 1 marked Yes.
At this point, the keyboard is now waitin for the receiver to identify itself usin the service PIN.
6. Momentarily short out the service PIN jumper on the receiver PCB (see fi ure 2).
The receiver neuron ID is transmitted onto the network, and the keyboard display will show the text Receiver Identified.
7. Type in the node ID you require this receiver to be confi ured to, and then press the Camera Select key.
After a short delay, the keyboard will then display the messa e Subnet Node Calculated.
8. After 10 seconds, the keyboard will then lo itself out automatically.
9. Repeat steps 1-3 to lo back on to the keyboard and o into self-bind mode.
10. Select a camera in the normal way by typin in the node ID and then pressin the Camera Select key.
11. Move the joystick. The PTZ will move, and the standard receiver screen will be displayed on the keyboard.
Troubleshooting
QI pressed the service PIN on the receiver, but the keyboard did not show the Receiver Identified messa e.
ANo data is comin throu h, check out the data cablin between the receiver and the keyboard.
QI ot to sta e 7, but the Subnet Node Calculated messa e remained on the keyboard screen and the keyboard did not

AData is only bein transmitted in one direction. Check to see if the data cable has been connected to the correct side
of the communications card, or that one side of the twisted pair has become disconnected.
Note
The AC receiver can also be addressed and installed usin the Pyramid Installation Tool. See the Pyramid Installation
Tool Operating Manual for more details.

Page 16
Pyramid AC Receiver Installation Manual
SETTING RECEIVER CONFIGURATION WITH THE PYRAMID 2 KEYBOARD
After a receiver has been addressed, the Pyramid 2 Keyboard can be used to specify the confi uration of the receiver
remotely via the Pyramid network.
To set the confi uration of a receiver, follow the steps below:
1. Enter the keyboard menu system. See the Pyramid 2 Keyboard Operating Manual for more details.
2. Select a monitor by enterin a number and pressin the Monitor key.
3. Enter the number of the receiver that is to be confi ured and press the Camera key.
4. Press the Utility Menu screen key.
5. Press the Receiver Utilities soft-key.
6. Press the Rx Config soft-key. The Receiver Configuration screen is displayed.
7. Some Pan/Tilt units are capable of continuous rotation (360O). A small ap can exist in the feedback potentiometer,
and this ap is known as the dead band. If a continuous rotation Pan/Tilt head is bein used, press the Non-Cont soft-
key, so that the receiver is confi ured for a continuous rotation Pan/Tilt unit. The text on the soft-key chan es to Cont.
The default settin is to leave the soft-key displayin the text Non-Cont (i.e., non-continuous Pan/Tilt head operation).
8. Receivers are supplied with feedback potentiometers enabled. If there are no feedback inputs to the receiver, the
manual operation of the Pan/Tilt unit will be affected (e. ., the pan and tilt controls will only operate in one direction),
since the feedback inputs are used as a constant check for end stops. If this is the case, disable the feedback
potentiometers to correct the problem and enable manual operation. To do this, press the F/B soft-key, so that the text
chan es to No F/B.
The default settin is to leave the soft-key displayin the text F/B (i.e., feedback potentiometers enabled).
9. In some cases, zoom lenses have three wire control of zoom and focus functions (i.e., Ground, Zoom +/-, Focus +/-)
rather than the usual four wire control. If this is the case, the receiver needs to be confi ured for the use of a 3-wire
lens, so that it carries out the zoom operation first followed by the focus operation on preset recall. To do this, press
the 3 Wire Lens soft-key.
The default settin is to leave the 3 Wire Lens soft-key off (i.e., in four wire control).

CAUTION
If the Pan/Tilt head connected to the receiver is not fitted with potentiometers the feedback pots function must be
disabled at step 5. If this is not done the pan and tilt operations will only work in one direction. If a Pan/Tilt head is
fitted with potentiometers ensure that mechanical limit stops are set and then press the test button on the receiver
PCB. This will ensure that the potentiometer directions are learnt correctly.
RECEIVER PROGRAMMING
The Pyramid 2 Keyboard can also be used to carry out more advanced receiver pro rammin (e. ., presets, privacy
zones, limit stops, random patrols). For more details on how to do this, see the Pyramid 2 Keyboard Operating Manual.
A copy of the manual is supplied with the Pyramid 2 Keyboard, and can also obtained from the Baxall website at
www.baxall.com, or from Baxall Technical Support.
Basic receiver pro rammin can also be achieved usin the Mk1 Keyboard. Instructions on how to do this can be
obtained from Baxall.

TESTING
Once the receiver has been addressed and confi ured, an on board test procedure can be activated which steps throu h
outputs in the sequence shown in the table below. The test procedure also allows the receiver to detect the feedback
polarity for the Pan/Tilt head and lens.
The test procedure runs when the test button is pressed with an appropriate tool (Fi ure 2). The test takes 57 seconds.
WARNING
 The AC receiver PCB now contains live voltages.
 Before running the test procedure fit the Pan/Tilt head in its intended position and ensure that it cannot collide
with anything or stretch any cables. Electrical and mechanical limit stops should be set to prevent such events.
Electrical limit stops can be set using the Pyramid 2 Keyboardconsult the Pyramid 2 Keyboard Operating
Manual for more details.

REPLACING THE LID
Once the necessary connections have been made and the receiver has been tested and addressed, refit the lid securely
to prevent unauthorised access. To do this, ti hten the four securin screws with an appropriate tool until they cannot be
undone by hand. Do not exceed a torque of 4 Nm.
CHANGING THE FUSE
The fuse holder (see Fi ure 2) contains a 10A A/S fuse for protectin the relay outputs.
To replace the fuse, switch off all power to the module, turn the top anti-clockwise usin an appropriate tool, chan e the
fuse and replace the top.
