5502DAL C-Bus DALI Gateway

2.0 Description

The 5502DAL C-Bus DALI Gateway unit is a C-Bus system support device designed to provide

an isolated communications path between a C-Bus Network and two DALI Networks. For ease

of installation the unit is DIN rail mounted, measuring 4M wide (1M = 17.5 +0.5/-0.0 mm).

3.0 Capabilities

The DALI Gateway provides two C-Bus connections through the use of RJ45 connectors,

allowing similar units to be quickly looped together. In normal operation, the unit draws 32mA

from the C-Bus Network. The DALI Gateway is capable of generating C-Bus Clock signals.

Each DALI Network can have up to 64 addressable DALI devices, such as fluorescent ballasts

and low voltage transformers. The DALI Gateway does not have its own DALI addresses, i.e. it

is transparent and is not "visible" for other DALI devices.

The DALI Gateway provides two-way communication, i.e. selected C-Bus messages are routed

to an appropriate DALI Network, and DALI lightning messages are routed to the C-Bus Network.

The DALI Gateway constantly monitors both DALI Networks. It is capable of detecting and

reporting to C-Bus faulty lamps in fluorescent ballasts or failed DALI units.

DALI Networks are insulated from C-Bus and from each other by optocouplers. The insulation is

capable of withstanding mains voltage.

In the initial release the unit contains a pre-programmed C-Bus to DALI and DALI to C-Bus

addressing structure.

SAFETY NOTE: DALI Networks are not rated as SELV despite of their low operating voltage of

16V. An assumption shall be made that a live mains voltage might occasionally appear on DALI

wiring because of wiring errors or insulation faults.

4.0 C-Bus Indicators

4.1 Unit/Comms Indicator

If the unit is powered and functional, the Unit/Comms indicator will be illuminated and

steady. During data transfer on the RS232 port the Unit/Comms indicator will flash.
