Status and external commands

UBIQUITY Routers have some LEDs on the front panel to provide visual feedback about device status and operation.

There are also two digital inputs for external commands and two digital outputs for electrical signals.

LED visual feedback

The common LEDs between all Router or Gateway devices are:

The RESET LED is AMBER (for first generation Routers) or RED.

The POWER LED is GREEN.

The RUN/STOP LED is bicolor GREEN/RED.

The REMOTE CONNECTION LED is GREEN (it’s available only for those devices with UBIQUITY).

The COM Rx/COM Tx LEDs are GREEN.

The following behaviors are defined:

  • Steady lighted

  • Blinking

  • Continuous sequence of a blink codes with a short pause in between to report a status

  • Single sequence of a blink code to report an event

LED

Status

Description

RESET

Steady lighted

Active when pressing the RESET button or when in presence of a non-recoverable hardware fault. See also below how this LED is used

POWER

Steady lighted

Active when the Router is properly powered.

RUN/STOP

Steady Green

UBIQUITY started and connected to the server.

Steady Red

UBIQUITY started but NOT connected to the server.

Blinking Green

UBIQUITY started and connecting to the server.

Blinking Red

UBIQUITY started but not connected to the server because not associated to any Domain.

Sequence of 2 red blinks

Connection attempt to a different domain than the first of the initial registration (see “Protection against unwanted Domain change).

Single 2 green blinks

Configuration from USB stick successfully completed.

Single 2 red blinks

User credential for Domain access not valid.

Single 3 green blinks

Start and Finish of the router update from USB stick (see update); during the entire update phase the LED continues to flash alternately red and green.

Single 3 red blinks

Router updated from USB Stick failed.

Single 4 red blinks

Factory restore started.

Note

During the Restoring factory settings, on RK2x RM2x DM2x Routers, the LED continues to flash alternatively red and green. At the end of the procedure, a sequence of red blinks indicate an error during restore.

Single 5 red blinks

UBIQUITY Runtime execution error, will follow a system restart.

Single 6 red blinks

USB stick data format not correct or unknown error.

REMOTE CONNECTION

Steady lighted

Active when at least one Control Center client is connected to the Router, otherwise off.

COM Rx COM Tx

Status and external commands

These LEDs are directly connected to the serial port Rx/Tx signals and they show traffic going through their lines.

Router RK/RM and Gateway GT/GR with integrated modem

The image32 LED is bicolor GREEN/RED.

The image33 LED is GREEN.

Icon

Status

Description

image32

Steady Red

The modem has not detected network signal.

Blinking Green

The modem has detected a weak signal from the network.

Steady Green

The modem has detected a strong signal from the network.

Blinking Red

SIM error (e.g. wrong PIN).

Off

The modem has not detected the SIM card.

image33

Blinking Green

Modem currently connected.

Off

Modem disconnected.

Router RK21 and RK22 with add-on carrier (Modem and Wi-Fi)

LED 3G/4G

Working color: AMBER (4G) o GREEN (2G/3G)

Status

Description

Off

The modem has not detected the SIM card.

Amber or Green low frequency blinking

The modem has detected network signal.

Amber or Green high frequency blinking

The modem is exchanging data.

Steady Red

The modem has not detected network signal.

Blinking Red

Malfunction or incorrect configuration (e.g. SIM in error status / incorrect PIN)

LED Wi-Fi

Working color: GREEN

Status

Description

Off

The Wi-Fi board is disabled.

Green low frequency blinking

The Wi-Fi board is connected to the network (Adapter mode) or is in Access Point mode. In both scenarios there is no data exchange.

Green high frequency blinking

The Wi-Fi board is connected and is exchanging data.

Red

Malfunction or incorrect configuration in Adapter mode.

Commands and Digital I/O

The following figure shows the label on the device side with the available commands and the terminal assignment.

image34

There are two commands designed for manual activation accessible from two buttons on the upper side of the device.

Command

Description

RESET

It forces the device restart. The command ensures a complete initialization of all internal electronics and software. The visual feedback of the operation is returned by the RESET LED. See LED visual feedback.

RESTORE FACTORY DEFAULT

It restores the Router to factory settings. All the settings are reset, all the system software is restored to the original version including the operating system, the firmware, the UBIQUITY Runtime and Domain registrations (identity is removed). To execute the restore, turn off the device, press and hold down the reset button and give power. You need to hold down the button until the starting of the restore process is indicated by the dedicated blink sequence of the LEDs. Wait for the process to be completed and the system to be rebooted. For first generation Routers, no LED signaling is performed during the restore procedure.

Danger

The duration of the update procedure can vary considerably from 1 minute to 5 minutes depending on the device (first or second generation UBIQUITY Router) and the number of software components involved.

It is essential, especially for first generation devices, that the device is not manually switched off or reset during the upgrade procedure, as this could irreversibly compromise its usage. In this situation, you should contact technical support. All references are available on the company website at the dedicated page:

There are 2 digital inputs to issue external commands and 2 digital outputs to report the device status via electrical signals.

The I/O signal meaning is reported in the following table.

Digital I/O

Description

IN0

This input works as “Connection mode”, also referred as “selector key” input. The status of this input is ignored by default. When the Router is configured to handle the input (see General Options in the Router configuration chapter) it can be used to externally control the connection to the server. The input can be driven by a mechanical selector, by a key selector or by a PLC outputs.

IN1

This input allows controlling the device restart externally. The operation corresponds to the Reset button. Power must be supplied for at least 10 seconds to reset the device. Once the command is received a proper feedback is returned by the status LED. See LED visual feedback.

OUT0

The output turns active when UBIQUITY Router is connected to the associated Domain. Note that the simple connection to the server does not activate the output, UBIQUITY Router is required to be successfully authenticated to the Domain.

OUT1

The output is active when at least one Control Center client is connected to the Router.
