Installation Manual - Iodine Converter

Discontinued product

The Iodine 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 Iodine protocol converter.

Power Supply​

power supply

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

SpecificationValue
Supply voltage12 VDC ±5%
Consumption (without peripherals)120 mA
Important

Use a regulated power supply rated to support the converter and all connected devices.

Wiegand/Abatrack Connections​

wiegand abatrack connection

The board identifies the connectors where the input devices (readers) and output devices (controllers) of the Wiegand/Abatrack data channel must be wired. The electrical level of this interface is open collector.

Device Voltage Selection​

There are two jumpers for selecting the supply voltage of the devices, with 5VDC or 12VDC options.

JumperFunctionOptions
JP1Voltage selection for the output device5VDC or 12VDC
JP2Voltage selection for the input device5VDC or 12VDC
Tip

The printed circuit board identifies, next to each jumper, the positions of each voltage option (12V or 5V).

UART Connections​

Buttons and LEDs​

The converter has two buttons that allow you to force a reset (boot) or put it into configuration mode, and it has POWER and STATUS indicator lights.

MODE button — puts the converter into configuration mode. Press and hold it for a few seconds.

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

POWER LED — indicates that the equipment is powered.

STATUS LED — reports the general state of the equipment.

Reading the STATUS LED​

When the converter is in operation mode, the STATUS LED provides information about the general state of the equipment. Every two seconds a series of up to two quick blinks starts. When two blinks are counted in each cycle, the situation is normal.

BlinkMeaning
1Converter in operation mode
2Network connection (Ethernet or WiFi) OK
Diagnostics

Checking these conditions through the STATUS LED helps a lot during installation and maintenance, to locate communication failures.

Starting the Configuration​

The Iodine converter is configured through a browser. To start the configuration, follow the steps below.

1. Activate Configuration Mode​

  1. Press and hold the MODE button for a few seconds.
  2. The converter enters configuration mode, keeping the STATUS LED blinking quickly.
  3. A WiFi Access Point (AP) is activated, allowing external connections (a tablet or mobile phone, for example).
Ending the configuration

At the end of the configuration session, briefly press the RESET button; the equipment returns to normal operation and the Access Point is deactivated.

2. Connect to the Converter's WiFi Network​

The WiFi network point created by the Iodine has a unique and exclusive name (SSID) for each converter, formed by the word iodine followed by a device identification code:

  • Format: iodine + identification code
  • Examples: iodineF67A, iodineF7A4

3. Access the Configuration Interface​

  1. Connect to the converter's WiFi network.

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

  3. Enter the default credentials:

    • User: admin
    • Password: iodinepwd

Installation Recommendations​

  1. Location: install the converter 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 the readers in environments with interference.
  5. Protection: consider using surge protectors on the power supply.
