Installation Manual - Neon Controller

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

Power Supply

The controller must be powered with 12 VDC ±5%.

Specification	Value
Supply voltage	12 VDC ±5%
Consumption (no 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 Neon controller has interfaces for two readers of the ABATrack or Wiegand type.

For each reader there is a jumper for supply voltage selection (JP1 and JP2) with options of 5VDC or 12VDC.

Reader Pinout

Reader 1:

Pin	Signal
+V	Positive supply
0V	GND
D0	Data 0
D1	Data 1
LED	LED control

Reader 2:

Pin	Signal
+V	Positive supply
0V	GND
D0	Data 0
D1	Data 1
LED	LED control

Reader Voltage Selection

For each reader there is a jumper for supply voltage selection:

JP1: Voltage selection for Reader 1
JP2: Voltage selection for Reader 2

Available options:

5VDC
12VDC

Tip

On the printed circuit board, the position of each voltage option (12V or 5V) is labeled 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 status 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 dry contact type, potential-free.

Command Relay Connections

The controller has four command relays with the following ratings:

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

Caution

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

Relay Functions

Relay	Channel	Function
LOCK 1	Channel 1	Activated on access granted
ALRM 1	Channel 1	Activated on access denied
LOCK 2	Channel 2	Activated on access granted
ALRM 2	Channel 2	Activated on access denied

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:

UART	Function	Signal Level
UART1	Configurable devices	TTL 5V or RS232
UART2	Configurable devices	TTL 5V or RS232
UART3	Special devices (e.g.: card collection bin)	TTL 3.3V

Serial Connector Pinout

Pin	Signal
1	+VCC
2	TX
3	RX
4	GND

Compatible Devices

The UARTs can be used to connect:

QR Code reading modules
Bluetooth modules
Biometric scanners
Printers
Card collection bin (IODINE)

LCD Display

The controller is ready for connection of an LCD display module with I2C communication.

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

Buttons and Indicators

RESET button - Forces the controller to restart (boot). Press briefly to exit configuration mode.

MODE button - Places the controller in configuration mode. Hold pressed for 5 seconds.

STATUS LED - Provides information about the general communication status.

STATUS LED Interpretation

The STATUS LED provides information about the general communication status:

Every two seconds a series of up to four rapid blinks is initiated:

Blink	Meaning
1	Controller in operating mode
2	Network connection (Ethernet/WiFi) OK
3	MQTT Broker connection OK
4	Server communication OK

Diagnostics

When four blinks are counted in each cycle, the status is normal. This check is very helpful during installation and maintenance for locating communication faults.

Starting Configuration

1. Activate Configuration Mode

Hold the MODE button for 5 seconds
The controller will initialize in Configuration mode
The STATUS LED will remain blinking rapidly
The controller activates a WiFi access point (AP mode)

2. Connect to the Controller's WiFi Network

The WiFi network access point created has a unique name (SSID) for each controller:

Format: neon + identification code
Examples: neon7512208F, neon89C0CF6A

3. Access the Configuration Interface

Connect to the controller's WiFi network
