DHCP (dynamic host controlled IP numbering) is
not
supported. When DHCP is working in your network, restrict
DHCP addresses, so that no device can take over an IP address reserved for the scanners. The scanner
electronic does not react on DHCP request nor does it send DHCP request.

The ping command can be sent from any PC in the network to verify, if the network operates, and if the target is
available for the network (“connected”). The ping command is sent using the “
Run”
Windows command line
interface from Windows start menu (with Linux use a “console”).
The M2DF-LAN-Scanners reacts on a ping command as every standard Ethernet network device.
Example of network collisions caused by duplicate addesses :
Address Scanner 1: 192.168.123.222;
Address Scanner 2: 192.168.123.223;
Address Scanner 3: 192.168.123.224;
Address Scanner 4: 192.168.123.225;
Address Scanner 5: 192.168.123.226;
Address Scanner 6: 192.168.123.227;
Address Scanner 7: 192.168.123.224; // wrong IP-Address = conflict with scanner # 3!
Address Scanner 8: 192.168.123.229;
Address Network card: 192.168.123.199
The Subnet mask for all Scanners and the network card = 255.255.255.0
Scanners, Gateway and PC need to be in the same network segment.

TCP Port
2 Byte, integer last segment in TCP/IP-address (for example 3000)
IP addresses of the gateways usually are at the start of the address range. Therefore numbers below .10 in the
last segment shall be kept free for routers and gateways.

IP addresses in a network segment differ only in the last three digits!
2
Serial-Numbers are set up at the factory; they can not be changed by the user!
