Installation Manual - Aurum Controller

Discontinued product

The Aurum has been discontinued and is no longer sold for new projects. This documentation remains available to support existing installations. For new projects or replacements, contact the Iongrade sales team.

This manual guides the designer or installer through the physical installation and the electrical connections of the Aurum access controller.

Power Supply

The controller must be powered with 12 VDC ±5%. Consumption, without readers and additional modules, is 120 mA.

Specification	Value
Supply voltage	12 VDC ±5%
Consumption (without peripherals)	120 mA

Important

Use a regulated power supply sized to support the controller and all connected peripherals (readers, locks, etc.).

Card Reader Connections

The Aurum controller has interfaces for three readers of the ABATrack or Wiegand type.

Each reader has a jumper for selecting the supply voltage, with options of 5 VDC or 12 VDC.

Reader Voltage Selection

To select the voltage of each reader, use the jumpers:

Jumper	Reader	Options
JP1	Reader 1	5 VDC or 12 VDC
JP2	Reader 2	5 VDC or 12 VDC
JP3	Reader 3	5 VDC or 12 VDC

Tip

The positions of each voltage option (12V or 5V) are identified on the printed circuit board, next to the jumpers.

Sensor and Command Button Connections

The signal inputs must be used for:

• REX (Request to Exit): command buttons
• DOOR SWITCH: door state sensors
• PAS SWITCH: turnstile rotation sensors

Input Pinout

Terminal	Function
PAS/DOOR 1	Passage/door sensor - Channel 1
REX 1	Exit button - Channel 1
PAS/DOOR 2	Passage/door sensor - Channel 2
REX 2	Exit button - Channel 2
COMUM	Common (GND)

Important

The sensors connected to these inputs must be of the dry contact type, potential-free.

Command Relay Connections

The controller has four command relays with the following capacities:

Specification	Value
AC load	1A / 120VAC
DC load	2A / 30VDC

Warning

Observe these limits to ensure the integrity and service life of the relay contacts.

Relay Function

The LOCK 1 or LOCK 2 relays are triggered when the controller grants access; the ALRM 1 or ALRM 2 relays are triggered when an access request is denied. The activation time settings are made during the controller configuration stage.

Relay	Channel	Function
LOCK 1	Channel 1	Triggered when access is granted
ALRM 1	Channel 1	Triggered on denied access
LOCK 2	Channel 2	Triggered when access is granted
ALRM 2	Channel 2	Triggered on denied access

Relay Pinout

Each relay has three terminals:

Terminal	Function
NF	Normally Closed
C	Common
NA	Normally Open

Serial Ports (UARTs)

The controller has three serial communication ports. The UART1 and UART2 ports are available for connecting various configurable devices. The UART VOC serial port is used for communication with the voice module.

UART Jumper Configuration

The controller has several jumpers for configuring the electrical level of the UARTs. On the printed circuit board, next to the jumpers, the correct positions for RS232 or TTL are identified.

UART 1:

Parameter	Options	Jumper(s)
Voltage for the device	5 VDC / 3.3 VDC	JP13
Electrical level	TTL / RS232	JP4, JP5, JP10, and JP11

UART 2:

Parameter	Options	Jumper(s)
Voltage for the device	5 VDC / 3.3 VDC	JP12
Electrical level	TTL / RS232	JP6, JP7, JP18, and JP9

UART VOC:

This port does not require jumper configuration. The signal level is TTL at 3.3 VDC.

Serial Connector Pinout

Pin	Signal
1	+VCC
2	TX
3	RX
4	GND

LCD Display

The controller is ready for the connection of a display module (LCD) with I2C communication. The electrical level of the signals is TTL at 5 VDC.

Pin	Signal
1	GND
2	+5VCC
3	SCL
4	SDA

Buttons and Indicators

RESET button — forces the controller to restart (boot). Press it quickly to exit configuration mode.

MODE button — puts the controller into configuration mode. Press and hold for 5 seconds.

STATUS LED — provides information about the general state of communication.

Reading the STATUS LED

When the controller is in operation mode, the STATUS LED provides information about the general state of communication. Every two seconds, a series of up to four quick blinks begins:

Blink	Meaning
1	Controller in operation mode
2	Network connection (Ethernet/WiFi) OK
3	Connection to the system Broker OK
4	Communication with the server OK

Diagnostics

When four blinks are counted in each cycle, the situation is normal. This check is very helpful during installation and maintenance to locate communication failures.

Starting the Configuration

The Aurum controller is configured through a browser. To start the configuration, follow the steps below.

1. Enable Configuration Mode

1. Press and hold the MODE button for 5 seconds.
2. The controller automatically starts in Configuration mode.
3. The STATUS LED keeps blinking quickly, indicating that the mode is active.
4. The controller activates a WiFi access point (AP mode) and starts accepting client connections.

2. Connect to the Controller's WiFi Network

The WiFi network created by the controller has a unique and exclusive name (SSID) for each controller:

• Format: aurum + identification code
• Examples: aurum7512208F, aurum89C0CF6A

3. Access the Configuration Interface

1. Connect to the controller's WiFi network.

2. Open the browser and go to: http://192.168.4.1

3. Enter the default credentials:

   • User: admin
   • Password: aurumpwd

From here on, see the Operation Manual to configure each controller screen.

Installation Recommendations

1. Location: install the controller in a place protected from the weather.
2. Ventilation: ensure adequate ventilation for heat dissipation.
3. Grounding: connect the grounding system properly.
4. Cabling: use shielded cables for readers in environments with interference.
5. Protection: consider using surge protectors on the power supply.

Next Steps

After completing the physical installation, see the Operation Manual to configure the controller.
