1700 Series Wafer Reader Section 6: System Settings
55
All of the settings that can be configured in the Network tab depend on whether this
checkbox is enabled. If enabled, the checkbox allows the wafer reader to be configured
automatically by a DHCP server at startup. Optionally, a new Host Name may be
assigned, but all other fields in the Network tab will be grayed out.
However, if the Use DHCP Server checkbox is disabled, the network settings
for the wafer reader must be configured manually. If the wafer reader was previously
assigned an IP address using DHCP, disabling the Use DHCP Server checkbox will use
the same IP address.
In production environments, a static IP address should be used instead of DHCP. Using a
static IP address removes the need for a DHCP server on the local network and
eliminates extraneous DHCP traffic.
IP Address
Assigns a unique identifier for each wafer reader on the network, which must be
consistent with the IP address-numbering scheme of the local network.
NOTE The IP Address setting is grayed out when the Use DHCP Server checkbox is enabled.
Unlike the factory-assigned MAC address, the IP address is assigned automatically by a
DHCP server or must be manually assigned by the user. The following IP addressing
schemes are recommended:
ADDRESSING SCHEME DESCRIPTION
10.0.0.0/8 The 10.0.0.0/8 private network is a class A network ID that allows valid IP addresses from 10.0.0.1
to 10.255.255.254. The 10.0.0.0/8 private network has 24 host bits which can be used for any
subnetting scheme within the private organization. The default Subnet Mask is 255.0.0.0.
172.16.0.0/12 The 172.16.0.0/12 private network can be interpreted either as a block of 16 class B network IDs
or as a 20-bit assignable address space (20 host bits) which can be used for any subnetting
scheme within the private organization. The 172.16.0.0/12 private network allows valid IP
addresses from 172.16.0.1 to 172.31.255.254. The default Subnet Mask is 255.255.240.0.
192.168.0.0/16 The 192.168.0.0/16 private network can be interpreted either as a block of 256 class C network
IDs or as a 16-bit assignable address space (16 host bits), which can be used for any subnetting
scheme within the private organization. The 192.168.0.0/16 private network allows valid IP
addresses from 192.168.0.1 to 192.168.255.254. The default Subnet Mask is 255.255.0.0
Subnet Mask
Defines which part of the wafer reader’s IP address refers to the network and which part
refers to the host.
NOTE When DHCP is enabled, this field is grayed out and displays the value assigned by DHCP.
