➢ TECHNICAL NOTE
Installation:
- Isolate the mains supply before the installation or adjusting the switches. Installation and maintenance must be performed in the absence of AC Voltage.
- Installation and maintenance must be performed only by qualified personnel in compliance with current regulations.
- The product must be installed inside an electrical cabinet protected against overvoltage’s.
- The external supply must be protected. The product must be protected from Fuse and/or Circuit Breaker with overcurrent protection correctly dimensioned
- The product must be installed only in a vertical or horizontal position with the cover / label pointing upwards or vertically; No other positions are allowed. Button-up positive is not permitted (downward label).
- The use of the product in harsh environments could limit the output power.
- Keep 230V circuits (LV) and non-SELV circuits separate from safety extra low voltage (SELV) circuits and from all connections of this product. It’s absolutely forbidden to connect for any reason, directly or indirectly, the 230V mains voltage to the bus or to other parts of the SELV circuit.
Command
- The length and type of the connection cables at the BUS (DMX512, DALI or other) must comply with the specification of the respective protocols and regulations and they should be isolated from every wiring or parts at voltage not SELV. It is suggested to use double insulated shielded and twisted cables.
- All the product and the control signal connect at the bus (DMX512, DALI, or other) must be SELV (the devices connected must be SELV or supply a SELV signal)
WARNING: Do not compromise the correct functioning of the device, the product must not be in any way shielded and/or installed inside metal and aluminum boxes.
As any other Casaba product, should not be placed in a metal enclosure or next to large metal structures. Metal will effectively block all radio signals which are crucial to the operation of the product.

➢ CBU-REPEATER-IP SETUP CASAMBI SIGNAL REPEATER

Characteristics:
The CBU-REPEATER-IP is a Casaba Repeater.
The device receives a Casaba Bluetooth signal and repeats it.
Status Led:
The status of LED is fixed on to indicate the correct power connection to the device.
TYPE OF PROFILE
| Type | # Profile | Name of Profile | Description |
| REPEATER | 9948 | REPEATER | It works as a repeater, forwarding the Casaba signal. |
➢ CBU-MASTER-DALI-IP SETUP CASAMBI SIGNAL CONVERSION INTO DALI PROTOCOL

CHARACTERISTICS:
The CBU-MASTER-DALI-IP is a Casaba to DALI Converter.
The device receives a command signal from Casaba APP and converts the signal into a DALI command. Send DT6 and DT8 command.
See the following table “ADDRESS MAP – DALI” for reference of Casaba-DALI conversion addresses.
STATUS LED:
- When the status of the LED is steady on, the Casaba module is configuring and addressing the SLAVE DALI devices connected to the bus.
- When the LED status flashes quickly, the Casaba module is sending the command set via the Casaba APP to the SLAVE DALI devices connected to the bus.
- When the LED status flashes slowly, it means the DALI bus is shorted.
- When the LED status is off there is no communication in the DALI bus.
AUTOMATIC DETECTION OF SHORT CIRCUITS IN THE DALI BUS:
When the device detects a short circuit on the DALI bus, it automatically switches off the power of bus and the LED signal flashes slowly.
At 15 seconds after the detection of the short circuit, CBU-MASTER-DALI tries to reactivate the power supply of the bus. If the short circuit has been solved, the system returns to work correctly, otherwise the bus remains unpowered and cyclically, every 15 seconds, the device tries again to reactivate the power supply of bus.
NOTE: CBU-MASTER-DALI-IP do not need a DALI Bus power Supply. At switching on, all channels are set at same value 254.

➢ CBU-MASTER-DMX-IP SETUP CASAMBI SIGNAL CONVERSION INTO DMX PROTOCOL 
Characteristics:
The CBU-MASTER-DMX-IP is a Casaba to DMX Converter.
The device receives the command signal from Casaba APP and convert it into a DMX command.
See the following “CHANNELS MAP – DMX” table for the reference of the Casaba-DMX conversion addresses.
Status Led:
Status LED is fixed on when the Casaba command is right transmitted.
Status LED slowly flashes (1 flash per second), when the device is powered.
