TRB142 RS232

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.
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: Output	Configurable 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.
