SICAM Q80 7KG8080
7.1.3.5
Establishing a PPP connection
As already explained in the introductory passages, a PPP connection actually remains transparent for its subscribers.
That means that the operating software makes no reference to the PPP connection; as far as it is concerned, the
connection is of the usual TCP/IP type. In consequence, the PPP connection must first be set up by Windows, before
starting the SICAM Q80 Manager software.
To establish the PPP connection, select the icon with the link SICAM Q80 7KG8080 in the Dial-Up Network which was
set up as per the instructions in the last section.
After the connection has been successfully established, a TCP/IP connection is ready for the SICAM Q80 Manager
software. Now a network search can be carried out in the manner usual under TCP/IP. For the network search, the
TCP/IP protocol is selected and the corresponding network interface (network adapter). The PPP connection appears
in the list of the network adapters with the TCP/IP address of the PC's Dial-Up Network. After the network search the
SICAM Q80 7KG8080 unit should appear in the list of hardware and can be selected.
Note
7.1.3.6
Disconnecting a PPP-connection
First disconnect from the device on the software level. Only after this is done, close the modem connection by
selecting Disconnect in the Dial-Up network. The device then returns to a standby state.
Note
7.1.3.7
Switching between Ethernet and PPP
Although the device has both a serial PPP and an Ethernet interface, only one interface can be used at a time.
Switching between the interfaces is accomplished by means of the modem control lines Data Set Ready (DSR) and
Data Carrier Detect (DCD). As a rule, it is sufficient to connect a modem to a serial interface. If the modem is switched
on, the device goes into standby. If the modem is switched off, or if no modem is connected, the Ethernet interface is
activated.
While communication is taking place, it isn't possible to switch. If you activated the modem while the device is
exchanging data with a PC via the Ethernet interface, this connection is not interrupted. Only after the PC has
completed its communication with the device is the modem's activation status checked.

In order to use SICAM Q80 7KG8080 via the PPP connection, first set up the connection via
the Dial-Up Network, then start the software.
Never break up a PPP-connection before having disconnected from the device. Otherwise it
takes a few minutes before the device can be addressed again.
When the device is switched from Ethernet to PPP, it takes about 40 seconds for a call to be
able to be received!
