RS232, Sync, RTU-to-RTU (MDLC)
For local connection to another RTU in synchronous mode, via RS232.
RS485, RTU Multi-drop (MDLC)
For local connection between two or more RTUs in asynchronous mode, via RS485.
User Parameters for Port 2
A description of the User parameters follows.
Link name
Contains the logical name of the link that the port is connected to. The link name is
automatically selected according to the Port Type parameters. For example, if the connection
type is Local Computer, then ToolBox automatically selects COMPUTER1 as link name. If
relevant, you can open the drop down list and select another name.
Data speed
If data speed is applicable to the port type parameters selected earlier, this parameter defines
the communication data speed of the selected media. The default is 9600. The IP Gateway
supports baud rates of up to 57,600.
Description
Enter your own description of the communications link (up to 40 characters).
Default Routing
Ensures RTU "mobility". The Default Routing parameter allows you to define the IP Gateway
as one that can be switched from one base station to the other by changing the radio frequency
(RadioX) or switching physical lines (LineX), but without changing the Link ID and the
MDLC network settings.
The choices are:
Choice Description
None This feature is not used.
To Slave(s) 1) If the IP Gateway serves as base station to a central
connected to it, then one of the ports must be defined as To
Master/Cntrl. All others must be set to None.
2) If the base station is the one that handles the data sent by the
IP Gateways, then one of its ports must be defined as To
Slave(s). This is the port through which the IP Gateway
communicates with the slaves.
To Master/Cntrl If the IP Gateway is used as "slave", then one of the ports
should be defined as To Master/Cntrl, and its Link ID must be
RadioX or LineX.
