Configuring the Serial Interface
This chapter describes configuring serial interface management.
The IR807 supports asynchronous serial interface protocols used for Raw Socket, SCADA Protocol Translation or reverse Telnet. It has two serial interfaces, designated async 0 and async 1.
Specifying an Asynchronous Serial Interface
To specify an asynchronous serial interface and enter interface configuration mode, use one of the following commands in global configuration mode.
Command or Action |
Purpose |
---|---|
Router(config)# interface async 0 |
Enters interface configuration mode. |
Specifying Asynchronous Serial Encapsulation
By default, asynchronous serial lines use the SCADA serial encapsulation method, which provides the communication between the Control Center and the RTU. The asynchronous serial interfaces support the following serial encapsulation methods:
- PPP
- Raw-TCP
- Raw-UDP
- SCADA
- SLIP
Command or Action |
Purpose |
---|---|
|
Configures asynchronous serial encapsulation. |
Encapsulation methods are set according to the type of protocol or application you configure in the Cisco IOS software.
The remaining encapsulation methods are defined in their respective books and chapters describing the protocols or applications.
Configuring the Serial Port
To configure the serial port perform the steps in the following example:
IR807#sh run int async 0
Building configuration...
Current configuration : 62 bytes
!
interface Async0
no ip address
encapsulation raw-tcp
end
IR807#sh run | sec line
line con 0
stopbits 1
line 1
exec-timeout 0 0
raw-socket tcp server 502
no exec
transport preferred none
transport input all
transport output none
stopbits 1
