Installation Manual - Cobalt

This manual guides the designer or installer through the specification and physical installation of the COBALT module, including the power supply, the connection terminal block, and the definition of the board role (Main or Subordinate).

Cobalt Module Connections

The table below describes the connections of the COBALT-QD32 terminal block, as identified on the board.

Connection	Terminals / Signals	Function
Power supply	12V, GND	Module power supply from an external 12 Vdc source
READER	D0, D1	Connection of an access control reader using the Wiegand protocol
Input/Emergency	input/emergência	Signal input active on low logic level
Digital outputs	output/relé 1 … output/relé 16	16 outputs that supply 12 Vdc to drive external relays
RS485	A, B	Expansion bus for connecting up to 3 additional modules

Power Supply

The Cobalt module is powered by an external 12 Vdc power supply, connected to the 12V and GND terminals.

Specification	Value
Supply voltage	12 Vdc (external power supply)

Important

Use a power supply sized to support the module and the set of external relays driven by the digital outputs.

Reader Connection (READER)

The READER interface is intended for connecting access control readers using the Wiegand protocol, through the D0 and D1 signals.

Terminal	Signal
D0	Wiegand data 0
D1	Wiegand data 1

Input/Emergency Input

The Input/Emergency input is active on low logic level and is intended for use in emergency situations, allowing all elevator buttons to be released.

Digital Outputs and External Relays

The 16 digital outputs supply 12 Vdc to drive the external relays responsible for the electrical switching of the elevator button circuits.

Terminal	Function
12V (output block)	12 Vdc reference for driving the relays
output/relé 1	Drives external relay 1
output/relé 2	Drives external relay 2
…	…
output/relé 16	Drives external relay 16

RS485 Connection (Expansion)

The RS485 interface is intended for connecting up to 3 additional modules over the bus, allowing the system to be expanded to up to 64 digital outputs.

Terminal	Signal
A	RS485 - A
B	RS485 - B

Buttons and Reset

When powered on, the module enters normal operation. The module has two buttons:

Button	Function
Download/Mode	Puts the module into configuration mode. Press and hold for eight seconds.
RESET	Restarts (reboots) the module.

Defining the Board Role: Main or Subordinate

The role of each board is defined by the communication media chosen in the configuration:

Configuration	Role	Connection used
Wi-Fi or Ethernet	Main	Communicates with the Accelero system and manages the Subordinate boards
RS485	Subordinate	Expansion unit, controlled by the Main board over RS485

Subordinate board

On a Subordinate board, the only configuration required is to enable RS485 communication and set the device ID. All other settings — network parameters, readers, floors, and system adjustments — must be made exclusively on the Main board.

Accessing the Configuration

The COBALT module is configured through a web browser. To start the configuration:

1. Activate configuration mode: power on the module, wait for normal operation, and press the Download/Mode button, holding it for eight seconds. The module restarts in configuration mode.

2. Wait about 30 seconds and check whether a new Wi-Fi network appeared, named cobalt followed by the serial number (e.g., cobalt012345).

3. Connect to the module's Wi-Fi network. The SSID is unique and exclusive to each module.

4. Open the browser at http://192.168.4.1 and enter the default credentials:

   • Username: admin
   • Password: cobaltpwd

Accelero compatibility

Operating the Cobalt module requires the Accelero platform version 2.16.9-HF3 or higher.
