Network interface are defined as general software application or hardware device that give the possibility to communicate with Robox Devices with different criteria than local connection (e.g. RS232 connections).

Interface types

Mainly there are three types of network interfaces:

1.Direct TCP/IP network connection, into a local area network (LAN) or more general wide area network (WAN), like Internet, via ethernet connection (see Ethernet network example).

2.Indirect TCP/IP via a Dialup Modem connection, using the standard PPP protocol (see Modem network example).

3.Direct Dialup Modem connection, using a raw protocol on the RS232 connector.

Integrated ETH port

Newer generation of RBXM (CPU586 and CPUG2) devices have an integrated ETH port that allow direct TCP/IP communication.

The integrated ETH inferface allow TCP connection through connection to port 8000, with BCC/31 over DLE/CRC16 transport.

Note: if configured, any TCP connection must authenticate before BCC/31 message can be processed : for more information look at bccNetLogin command. Message not allowed (even after authentication), are denied with a bccNack response with nackNotAuthorized error code.

NET.INT. expansion board

The NET.INT. is no more in use since newer RBXM devices have their own integrated ETH port.
