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


Summary

The Serial Utilities page is used to make serial communication configurations of different types. This manual page provides an overview of the Serial Utilities page in {{{name}}} devices.



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.

[[File:Networking_rutos_manual_serial_utilities_console_default_{{{default}}}_v1.png|border|class=tlt-border]]

Field Value Description
Enable off | on; default: off Turns the instance on or off.
Name string; default: none Instance name, generated by the user when first creating the configuration.
Device ; default: Specifies which serial port will be used for serial communication.
Baud rate integer [300..3000000]; default: 9600 Data rate for serial data transmission (in bits per second (bps)).
Data bits 8; default: 8 Number of data bits for each character.
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 resynchronize with the character stream. Electronic devices usually use one stop bit. Two stop bits are required if slow electromechanical devices are used.
Parity None | Odd | Even | Mark | Space; 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.
Flow control None; 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.

Over IP

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

Serial Device Configuration


Configure serial port communication parameters in the Serial Device Configuration section.

Over IP Configuration Settings


You can configure network related parameters of the serial connection in the Over IP Configuration secion.

Field Value Description
Mode Server | Client | Client + server | Bidirect; default: Server This device's role in the connection:
  • Server - the device waits for incoming connections.
  • Client - the device initiates the connection.
  • Client + server - launches service in server and client(s) mode simultaneously.
  • Bidirect - acts as client by default but waits for incoming connections at the same time.
Protocol TCP | UDP; default: TCP Protocol used in the communication process.
Client: Destination address IP | Port; default: empty Specify server address and port for client to connect to. E.g first field for address second for port. 16 destination addresses are allowed.
Server: UDP: Predefined addresses IP | Port; default: empty Set predefined IP and port for UDP connection. E.g first field for address second for port.
Listening port [1..65535]; default: empty When enabled, all data will be transmitted transparently.

Field Value Description
Use TLS/SSL off | on; default: off Mark to use TLS/SSL for connection.
TLS version Support all | tlsv1.0 | tlsv1.1 | tlsv1.2 | tlsv1.3; default: Support all Minimum TLS version allowed to be used.
TLS type Certificate based | Pre-Shared-Key based; default: Certificate based Select the type of TLS encryption.
Require certificate off | on; default: on Demand certificate and key from peer and verify them against certificate authority.
Verify host off | on; default: off Check if the server certificates Common Name (CN) matches hostname to which client is connecting.
Certificate files from device off | on; default: off Choose this option if you want to select certificate files from device.
Certificate files can be generated <a class=link href="/system/admin/certificates/generation">here</a>.
Certificate file .crt file; default: none Upload certificate file.
Key file .key file; default: none Upload key file.
CA file .ca file; default: none Upload CA file.
Pre-Shared-Key string; default: none The pre-shared-key in hex format with no leading “0x”.
Identify string; default: none Specify the identity.

Field Value Description
Raw mode off | on; default: on When enabled, all data will be transmitted transparently.
Remove all zeros off | on; default: off When checked, indicates that the first hex zeros should be skipped.
Inactivity timeout integer [0..36000]; default: 300 Specifies period of time in seconds, where server connection must be inactive, to disconnect client. To disable timeout input 0.
Serial timeout integer [0..1000]; default: none Specifies the maximum milliseconds to wait for serial data.
Max clients integer [1..32]; default: 4 Specify how many clients are allowed to connect simultaneously.
TCP echo on | off; default: off Enable software TCP echo.
Close connections on | off; default: off Close TCP connections everytime data is sent or received (might result in serial data loss).
Keep alive on | off; default: off Enable keep alive.
Keep alive time integer [0..32000]; default: 0 Close TCP connections everytime data is sent or received (might result in serial data loss).
Keep alive interval integer [0..32000]; default: 0 The interval between subsequential keepalive probes.
Keep alive probes integer [0..32000]; default: 0 The number of unacknowledged probes.

IP Filter


The IP Filter section is used for configuring which network is allowed to communicate with the device. You may add a new instance by selecting the Interface and pressing Add.
