RUTX08 Serial Utilities

The information in this page is updated in accordance with firmware version RUTX_R_00.07.04.
Note: services were merged and moved to Serial Utilities page from FW version RUTX_R_00.07.03.

Summary

The Serial Utilities page is used to make serial communication configurations of different types.

To make a new serial configuration instance select a serial type from the left-hand navigation menu. In the next page enter a custom name for the new config, select a serial device and click the Add button.

Example from the Modem Configuration page:

Then, click the Edit button next to the instance:

This manual page provides an overview of the Serial Utilities page in RUTX08 devices.

Modem Control

The Modem serial type is used to manage modem functionality which could be accessed using shell interface. For this purpose you may want use CR/LF (Carriage Return, Line Feed) capable applications like PuTTY on Windows and microcom, minicom, cutecom or similar applications on Linux.

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	USB RS232 interface; default: USB RS232 interface	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	7 | 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 resynchronise 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.
Mode	Partial control | Full control; default: Partial control	Specifies modem control mode. Partial control- enables modem control with AT commands, mobile connection will be controlled by RUTOS. Full control- enables modem control with AT commands, mobile connection will be controlled by user.

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.

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.

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

Raw mode	off | on; default; default: off	When enabled, all data will be transmitted transparently.
No leading zeros	off | on; default: off	When checked, indicates that the first hex zeros should be skipped.

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.

Then enter the IP address and save.
