2.3.4 Step 3 – Setting up the PPP communication
The following chapter describes how to set up communication via PPP using Windows 2000
8
. The
SC11 does not have an Ethernet network interface. However, TCP/IP can be implemented with PPP,
so that it is still possible to use the features of the IPC@CHIP such as FTP and Telnet.
In the following description, it is assumed that the SC11 functions as a PPP server and is connected to
your PC via the null-modem cable, i.e. your PC must establish a connection to the passive SC11.
The PPP server of the IPC@CHIP must be configured in the CHIP.INI configuration file so that it can
be used. You can create this file on your PC and then transfer it to the SC11.
Open any text editor (e.g. Notepad) and enter the following text

.
[PPPSERVER]
ENABLE=1
COMPORT=EXT
ADDRESS=192.168.200.1
REMOTEADDRESS=192.168.200.2
NETMASK=255.255.255.0
IDLETIME=0
FLOWCTRL=2
MODEM=1
AUTH=2
BAUD=115200
USER1=ppps
PASSWORD1=ppps
CONNECTMSG0=CLIENT
CONNECTANSWER0=CLIENTSERVER
CONNECTMSG1=NULL
CONNECTANSWER1=NULL
CONNECTTIMEOUT0=0
CMDMODE=NULL
[SERIAL]
EXT_RECVQUEUE=4096
EXT_SENDQUEUE=4096
Only the most important entries are explained as the exact meaning of each entry in the configuration
file does not have to be understood for commissioning:
• ENABLE=1 activates the PPP server.
• COMPORT=EXT specifies that the EXT interface of the IPC@CHIP is to be used for the
connection.
• ADDRESS=192.168.200.1 defines the IP address of the IPC@CHIP for the PPP connection. This
IP address can be used to access the IPC@CHIP after the configuration is completed.
• REMOTEADDRESS=192.168.200.1 defines the address that is to be assigned to your PC for the
PPP connection. If you have installed several components on your PC that use TCP/IP, you
should ensure that the IP addresses defined here are not in the same subnet as those of other
components.
• USER1=ppps and PASSWORD1=ppps define the access data with which the client (your PC)
must later log on to the server. You can also define other user name password combinations. (e.g.
USER2=ppps2 and PASSWORD2=ppps2)

The procedure described is slightly different for other Windows versions.

When using other Windows versions, a slightly different form of the chip.ini configuration file shown here must be used. You
can download configuration files for different versions from the Beck Getting Started web site.
