Field Value Description
Protocol TCP | UDP; default: TCP Protocol used in the communication process.
Raw mode off | on; default; default: off When enabled, all data will be transmitted transparently.
Mode Server | Client | Bidirect; default: Server This 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 | TCP: Timeout (s) integer [0..32767]; default: 300 Specifies an inactivity time limit (in seconds) after which an inactive clients is disconnected.
Bidirect: OutputConfigurable Input/Output (3) | Configurable Input/Output (4); default: Configurable Input/Output (3) Specifies which output to manage.
Bidirect: Output state 0 | 1; default: 0 Default output state value, when the application is started.
Server settings | UDP: Number of clients 1-10; default: 1 Specifies how many UDP clients will be supported simultaneously (predefined clients does not count towards this limit).
Server settings | UDP: Predefined client 1 address ip4; default: none Specifies IP address for predefined connection 1.
Server settings | UDP: Predefined port 1 port; default: none Specifies port number for predefined connection 1.
Server settings | UDP: Predefined client 2 address ip4; default: none Specifies IP address for predefined connection 2.
Server settings | UDP: Predefined port 2 port; default: none Specifies port number for predefined connection 2.
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.
Serial device read time integer [0..1000]; default: none Specifies custom read time for the serial device.
Echo off | on; default: off Turns RS232 echo on or off. RS232 echo is a loopback test usually used to check whether the RS232 cable is working properly.
Server settings | TCP: Max clients integer [1..32]; default: 32 Specifies how many clients are allowed to connect simultaneously.
TCP: CD pin indication off | on; default: off Enable to use CD pin for TCP connection state indication.
TCP: CD pin invert off | on; default: off Change default status to active (Active when no connection).
TCP: DSR pin indication off | on; default: off Enable to use DSR pin for TCP connection state indication.
TCP: DSR pin invert off | on; default: off Change default status to active (Active when no connection).
TCP: Always reconnect off | on; default: off When enabled, a new TCP connection will be made after sending every data package.

Modem


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

Field Value Description
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.
