2680A/2686A

Getting Started Guide

Reviewing and Setting the Subnet Mask and Default Gateway

If communication between the host computer and the 2680 Series passes through a router or gateway, you must set the subnet mask and default gateway address on both the host computer and the device. Get this information from your network administrator.

Perform the procedure in Table 7 to review or set the device network gateway parameters. The network gateway parameters include turning the default gateway feature on or off, setting a subnet mask, and setting an IP address for the gateway attached to the local network.

Note

Set the IP address of the device before setting the gateway parameters. The 268XA device checks the gateway IP address for validity by using the device IP address.

Default Gateway Parameters If the 268XA device and host PC are on different subnets and must communicate through a gateway (router), turn the default gateway feature ON and enter the subnet mask and IP address of the gateway, as supplied by your network administrator. If you do not require a gateway, turn the default gateway feature OFF.

Subnet Mask The subnet mask is a 32 bit binary number expressed as four

3 digit segments, like an IP address. The subnet mask, when masked with the device IP address, determines what the network number is. For example, if the IP address is 129.196.180.93 and the subnet mask is 255.255.255.0, the network number is 129.196.180.0.

The subnet mask contains a consecutive set of bits, starting at the highest order bit, forming a binary mask value. For example, 255.255.0.0 (binary value FFFF0000 hex) is a valid mask, but 255.255.10.0 (binary value FFFF0A00 hex) is not a valid mask, because the bits are not consecutive. 0.255.255.0 (binary value 00FFFF00 hex) is also not a valid mask, because the bits do not begin at the highest order bit.

The subnet mask must also contain a minimum number of bits depending on the class of the device IP address. The minimum number of bits for a class A address is 255.0.0.0, class B is 255.255.0.0 and class C is 255.255.255.0. For example, if the IP address is 129.196.180.93, a class B address, a subnet mask of 255.0.0.0 is not valid, because there are too few subnet mask bits set.

Default Gateway IP Address The default gateway IP address is the IP address of a gateway (router) attached to the same network as the device. When the device detects that a host PC is not on the same network (using the network number), the data is sent through the gateway to reach the host PC.
