The information in this page is updated in accordance with firmware version .

Summary

The USB Tools page is used to manage services related to the device's USB connector.

This chapter of the user manual provides an overview of the USB Tools page in {{{name}}} devices.

If you're having trouble finding this page or some of the parameters described here on your device's WebUI, you should turn on "Advanced WebUI" mode. You can do that by clicking the "Advanced" button, located at the top of the WebUI.

General

The General section is used to manage global USB settings. It consists of two subsections:

USB Mount Settings

The USB Mount Settings section is used to set the transfer type (synchronous or asynchronous) for the USB device.

Synchronous ensures that all changes to the according filesystem are immediately flushed to disk. Enabling this will drastically lower the life expectancy of your USB device.

Mounted File Systems

The Mounted File Systems list displays USB mass storage devices (MSD) currently attached to this device.

Field	Value	Description
Device	filepath; default: /dev/sd*	The filesystem of the attached USB MSD.
Mount Point	filepath; default: /mnt/sd*	The root directory of the mounted filesystem.
Available	string; default: none	Displays available storage information for a mounted USB MSD.
Used	string; default: none	Displays used storage information for a mounted USB MSD.
In Use	string; default: none	Indicates whether a USB MSD is currently in use by some device service or not.

The Format button can be used to format the attached device, and the Unmount button next to each entry in the list is used to unmount an attached USB device. Please make sure to unmount a USB device before physically detaching it from the {{{name}}}.

The Refresh is used to refresh the information in the Mounted File Systems list. If you attach a new USB device and cannot see it in the list, try clicking the 'Refresh' button.

Note: Usb with NTFS partition is supported in read-only mode.

Printer Server

The Printer Server feature provides the possibility to configure access to a printer that is connected to the USB port of the device. After the printer is connected to the device's USB port and configured, it can be utilized by users in the local network (LAN, WiFi) or remotely.

The 'Add' button lets you add and manage additional printers. To configure a printer instance, click the Edit button located next to it:

Field	Value	Description
Enable	off \| on; default: off	Turns USB printer support on or off.
Device	filepath; default: /dev/usb/lp0	Printer's device file.
Port	integer [9100..9109]; default: 9100	Printer's TCP port.
Bidirectional mode	off \| on; default: on	Turns bidirectional mode on or off.

USB to Serial

The device's USB connector can also be used as a serial port.

Field	Value	Description
Enabled	off \| on; default: off	Turns the USB to Serial service on or off.
Baud rate	300 \| 1200 \| 2400 \| 4800 \| 9600 \| 19200 \| 38400 \| 57600 \| 115200; default: 115200	Data rate for serial data transmission (in bits per second).
Data bits	5 \| 6 \| 7 \| 8; default: 8	Number of data bits for each character
Parity	None \| Odd \| Even; default: None	In serial transmission, parity is a method of detecting errors. An extra data bit is sent with each data character, arranged so that the number of 1 bits in each character, including the parity bit, is always odd or always even. If a byte is received with the wrong number of 1s, then it must have been corrupted. However, an even number of errors can pass the parity check. None (N) - no parity method is used Odd (O) - the parity bit is set so that the number of "logical ones (1s)" has to be odd. Even (E) - the parity bit is set so that the number of "logical ones (1s)" has to be even.
Stop bits	1 \| 2; default: 1	Stop bits sent at the end of every character allow the receiving signal hardware to detect the end of a character and to resynchronise with the character stream. Electronic devices usually use one stop bit. Two stop bits are required if slow electromechanical devices are used.
Flow control	None \| RTS/CTS \| Xon/Xoff; default: None	In many circumstances a transmitter might be able to send data faster than the receiver is able to process it. To cope with this, serial lines often incorporate a "handshaking" method, usually distinguished between hardware and software handshaking. RTS/CTS - hardware handshaking. RTS and CTS are turned OFF and ON from alternate ends to control data flow, for instance when a buffer is almost full. Xon/Xoff - software handshaking. The Xon and Xoff characters are sent by the receiver to the sender to control when the sender will send data, i.e., these characters go in the opposite direction to the data being sent. The circuit starts in the "sending allowed" state. When the receiver's buffers approach capacity, the receiver sends the Xoff character to tell the sender to stop sending data. Later, after the receiver has emptied its buffers, it sends an Xon character to tell the sender to resume transmission.
Serial type	Console \| Over IP \| Modbus gateway \| NTRIP client; default: Console	Specifies the serial connection type. Look to the sections below for information on different USB to Serial type options.

Console

Console mode requires no further configuration than the settings above and is used as a direct-access method to the device's shell interface. For this purpose you may want use such applications as PuTTY on Windows and microcom, minicom, picocom or similar applications on Linux.

Over IP

The Over IP serial type is used to manage serial connections over a TCP/IP network.

Field	Value	Description
Protocol	TCP \| UDP; default: TCP	Protocol used in the communication process.
Mode	Server \| Client \| Bidirect; default: Server	The role of this device in the serial connection: Server - the device waits for incoming connections Client - the device initiates the connection. Bidirect - acts as client by default but waits for incoming connections at the same time.
No leading zeros	off \| on; default: off	When checked, indicates that the first hex zeros should be skipped.
Server settings: Port	integer [0..65535]; default: none	Internal port number used to listen for incoming connections.
Server settings: Timeout (s)	integer; default: none	Specifies an inactivity time limit (in second) after which an inactive clients is disconnected.
Server settings: Open port automatically	off \| on; default: on	Automatically adds a traffic rule in the firewall configuration to open the required port for NTRIP communication.
Client settings: Server Address	ip \| host; default: none	IP address or hostname of the server that this client will connect to.
Client settings: Port	integer [0..65535]; default: none	Server's listening port number.
Client settings: Reconnect interval (s)	integer; default: none	Time period (in seconds) between reconnection attempts in case a connection fails.
Echo	off \| on; default: off	Turn USB to serial echo on or off.

Modbus gateway

The Modbus gateway serial type allows redirecting TCP data coming to a specified port to an RTU specified by the Slave ID. The Slave ID can be specified by the user or be obtained directly from the Modbus header.

Field	Value	Description
Listening IP	ip; default: 0.0.0.0	IP address to listen for incoming connections. The default value (0.0.0.0) means that this device will listen for incoming connections on any interface or IP address.
Port	integer [0..65535]; default: 502	Port number to listen for incoming connections.
Slave ID configuration type	User defined \| Obtained from TCP; default: User defined	Specifies whether slave IDs are user defined or automatically obtained from TCP.
Slave ID \| Permitted slave IDs	integer \| range of integers; default: 1 or 1-247	Specifies the slave ID of range of permitted slave IDs. The way this field is named and its function depends on the value of the Slave ID configuration field. A range of IDs can be specified by placing a hyphen (-) between two integer numbers. For example, if you permit slave IDs in the range of 10 to 20, you would specify it as: 10-20 You can also specify multiple values that are not connected in a range using commas (,). For example, to specify 6, 50 and 100 as permitted slave IDs, you would have to use: 6,50,100
Open port automatically	off \| on; default: on	Automatically adds a traffic rule in the firewall configuration to open the required port for serial communication. Caution: use with care if listening IP is left as the default value (0.0.0.0). Leaving it as such will leave the device open for remote connections on the specified port.
Echo	off \| on; default: off	Turn USB to serial echo on or off.

NTRIP client

Networked Transport of RTCM via Internet Protocol (NTRIP) is a protocol for streaming differential GPS (DGPS) data over the Internet in accordance with specification published by RTCM.

Field	Value	Description

To connect to the router's SAMBA server from Windows, specify the address in this format:

\\smb_server_address\share_name

Replace smb_server_address with the IP address of this device or SAMBA share hostname; replace share_name with the name of the "share" (as specified in the 'Name' field). For example:

\\192.168.1.1\my_share \\Router_share\johns_files

Users

The Users section is used to create Samba users that can be granted access to Shared Directories. To add a new user, enter a custom username, password and click the 'Add' button.

The newly added User should appear in the Users list. To change the password of a Samba User, click the 'Edit' button located next to it:

This will redirect you to the Settings page for that User which should look similar to this:

DLNA

The Digital Living Network Alliance (DLNA) standard provides the possibility to stream media files from local storage to DLNA-capable devices such as computers, Smart TVs, tablets, etc.

This page is used to configure the DLNA service on the device. When the DLNA service is enabled, the device listens for incoming connections on the specified network interface and port number. Clients connecting to that port number on that interface will be granted access to the media files residing in the specified directories.

DLNA devices use Universal Plug and Play (UPnP) to discover and communicate with each other on a network. To access the DLNA server hosted on this device you will need a DLNA-capable application. If you're using your phone or other mobile device, simply search for DLNA in the device's application store. On Linux and Windows computers you can use applications capable of playing network media streams (such as VLC). Smart TVs and similar devices may have DLNA support built-in by default.

File format types supported by the DLNA service on this device:

Audio - WMA, WAV, MP3, FLAC
Image - JPEG
Video - WMV, MTS, MP4, MKV, MOV

Note: DLNA is additional software that can be installed from the System → [[{{{name}}} Package Manager|Package Manager]] page.

General Settings

Field	Value	Description
Enable	off \| on; default: off	Turns the DLNA service on or off.
Port	integer [0..65535]; default: 8200	DLNA service listening port.
Friendly name	string; default: Teltonika DLNA Server	The name of this server as it will be displayed to clients.
Root container	Standard container \| Browse directory \| Music \| Video \| Pictures; default: Standard container	Specifies which type of files will be made available in DLNA file sharing. Standard container - allows browsing the shared media directory but also organizes files by type (music, video, pictures). Browse directory - allows browsing the shared media directory . Music, Video, Pictures - only shares the files of the specified type.
Media directories	filepath(s); default: /mnt	A list of directories that will be scanned by the DLNA service and made available to clients. You can also specify what types of files should be displayed from the directy. Use 'A' for audio, 'V' for video, 'P' for images followed by a comma and the path to the directory. For example: A,/mnt - share only audio files from the /mnt/sda1 directory. V,/mnt - share only video files from the /mnt/sda1 directory. P,/mnt - share only image files from the /mnt/sda1 directory. Click the plus symbol to add more directories.
Album art names	filename(s); default: Album.jpg	Name of the file(s) to check when searching for album art images. Click the plus symbol to specify more file names.
