Summary

The USB Tools page is used to set up USB printer settings. After the printer is connected to the router's USB port and configured, it can be utilized by users in the local network (LAN, WiFi) or remotely.

This manual page provides an overview of the Printer Server page in {{{name}}} devices.

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. 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 printer support on or off.
Device file path; 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 Enables the RS232 service
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 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 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 Device's role in the 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.
Client settings: Server Address ip | host; default: none IP address or hostname of the server that the 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.
Open port automatically off | on; default: on Automatically adds a traffic rule in the firewall configuration to open the required port for serial communication.
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 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.
Port integer [0..65535]; default: none 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.
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
IP address ip; default: 0.0.0.0 IP address of an NTRIP server.
Port integer [0..65535]; default: none TCP/UDP port used for NTRIP communication.
Mount point file path | string; default: none NTRIP mount point.
Data format NTRIP V2.0 TCP/IP | NTRIP V2.0 RSTP/RTP | NTRIP V1.0 | Automatic detection | NTRIP V2.0 UDP; default: NTRIP V1.0 Version of NTRIP protocol.
Username string; default: none User name for authentication to NTRIP server.
Password string; default: none Password for authentication to NTRIP server.
Default NMEA string string; default: none Optional NMEA string that will be used as the default value when initiating the connection to the NTRIP server (this value is only sent to the server if there is no NMEA from router's GPS device).
Use device GPS off | on; default: off Allows to obtain default NMEA string from the router's GPS device. Only works if GPS service is enabled and location fix is obtained at the time of NTRIP service start.
Open port automatically off | on; default: on Automatically adds a traffic rule in the firewall configuration to open the required port for serial communication.
Echo off | on; default: off Turn USB to serial echo on or off.
