Installation Manual Pyramid Universal Dome Interface

CONNECTING AND CONFIGURING THE UDI

Dip switch number 6 is used to enable or disable the auto-iris function. If the auto-iris functionality is enabled

(dip switch 6 UP), the iris level on the connected device will be readjusted for the lighting conditions every thirty

seconds. If this functionality is disabled (dip switch 6 DOWN), iris adjustments will have to be made manually

using a system keyboard.

Service Pin - The service pin is used to address the UDI. When the service pin is pressed (use a small

screwdriver to do this), the service pin LED will light and a unique identifier known as a neuron ID is transmitted

to all other devices that are connected to the UDI. The purpose of this is to establish communication between

the UDI and the other devices in the Pyramid network.

Dome Data LEDs - The LED labelled Rx lights to indicate when data is being sent from the dome camera to the

UDI. The LED labelled Tx lights to indicate when data is being sent from the UDI to the dome camera. This

allows for easy system diagnosis.

Dome Data Connector - This three-way terminal block is used to connect the UDI to the dome camera. At the

UDI end, the connections are common. The dome camera is connected to the UDI using pins 2 and 3 (labelled

- and +) and a ground connection should be made on pin 1.

The connections at the dome camera end are dependent on the type of dome camera in use. See the relevant

section for more details about the connections that need to be made at the dome camera.

Alarm Input Connector - Up to four alarm inputs can be connected to the UDI using this terminal. Connect

each alarm input to one of the four numbered pins, and make a common connection for each input to the pin

labelled with a C (common).

When alarm inputs are connected to the UDI, they will use the address that is assigned to the UDI itself. For

example, if the UDI is assigned camera address 21, the alarm inputs will be assigned to alarm input unit 21.

Once the unit has been addressed and connected to the Pyramid network, the alarm inputs can be configured

in the same way as a Pyramid Alarm Input Module. This would be done using the Pyramid Matrix menu

systemfor more details, see the Pyramid Matrix Programming Manual.

A UDI addressed between 127 to 144 will use the alarm input box references 1 to 18 respectively (see table

below). For example, an alarm input from UDI 143 holds an alarm box input address of 17.

UDI address numbers 1 2 ... 126 127 128 ... 144

Alarm box address numbers 1 2 ... 126 1 2 ... 18

The state of the alarm inputs (i.e., all normally-open or all normally-closed) can also be configured using dip

switch 4 on the four-way switch bank

. If the switch is in the OFF position (down) then all the alarm inputs are

normally-closed. If the switch is in the ON position (up), then all the alarm inputs are normally-open.

Pyramid Data LEDs - The LED labelled Tx lights to indicate when data is being sent from the UDI to the

Pyramid network. The LED labelled Rx lights to indicate when communication is taking place on the Pyramid

network (not just to the UDI). This allows for easy system diagnosis.

Biasing Switches - Pyramid networks should be biased and terminated. Typically, biasing is applied to the first

module of a network and termination is applied to the first and last modules. All other modules should be

unbiased and unterminated. If it is necessary to apply biasing to the UDI, move both dip switch 1 and 2 into the

UP position. To apply termination to the UDI, move dip switch 3 into the UP position.

Dip switch 4 is used to set the state (i.e., all normally-open or all normally-closed) of any alarm inputs that are

connected to the UDI. See Alarm Input Connector

for more details.

Note

For connections to BT, Teleste and AMG fibre optic equipment, no biasing should be applied.
