COMMUNICATION INTERFACE CONFIGURATION
Two hardware interfaces are provided for the communication with the device:
a serial interface and an Ethernet interface.
The serial interface can be used for the basic network setup of the device.
The Ethernet interface is used for the operation via Web Interface or for
operation via SNMP.
4.4.1
Serial Interface
The Sub-D 9 pos female connector labeled "RS 232" for the standard serial
interface is located at rear side of the chassis; for the pin assignment please
refer to chapter 7.
The following parameters describe the serial interface configuration:
Transmission rate:
38400
Data bits:
8
Parity check:
none
Start/Stop bit:
1
Handshake:
none
4.4.2
Ethernet Interface
The RJ-45 connector labeled "Ethernet" for the standard 100Base-TX
(IEEE 802.3, Clause 24) Ethernet interface is located at the rear side of the
chassis; for the pin assignment please refer to chapter 7.
4.4.2.1 Ethernet Connection
If the standalone device is to be connected to a PC only, the connection can
be established by a crossed Ethernet cable (or via a local hub/switch with
straight Ethernet cables) and the network setup of the PC is to be altered,
that it is in the same subnet as the device. So, if it is intended to use the
factory default network settings, the IP address of the standalone PC should
be set to 192.168.0.xxx, with xxx ranging from 001…254, except 11 which is
the address of the device, e.g. set the IP address of the standalone PC to
default gateway address 192.168.0.99.
If the device is to be connected to the local network, make sure to change
the network setup as required. Ask your system administrator for the details
on network parameters which are to be used.
The factory default network settings are subject of chapter 4.3.2.
There are two different methods to change the network setup of the device.
First, the network setup can be changed via Web Interface (Setup Tab
→
IP Configuration), please refer to chapter 5.4.5.3. The other method that can
be performed is subject of the following chapter.
4.4.2.2 Network Setup via the Serial Interface
To change a few elementary parameters of the network setup of the device
via the serial interface, establish a hardware connection between a PC serial
port (e.g. COM1 or COM2) and the RS 232 interface of the device ("RS 232"
