Computer Interfaces 4-9
Setting the Gateway
Setting the gateway is similar to setting the IP address. The
gateway is made up of four octets. Set the gateway by entering the
four octets, one at a time.
1. Press key 3 to select line 3. Rotate the knob until line 3
appears as follows (line 4 may differ):
-----SETTINGS-----
Type: TCP/IP
> Option: GW_Oct_1 <
Status: 0
This prepares the 1256 to set the first octet
(eight bits) of the gateway.
2. Select line 4 and rotate the knob until line 4 displays the first
octet of your desired gateway. Then press key 4 again to
confirm.
3. Proceed with the remaining octets of the gateway until all four
are set.
Setting the Sub-Net Mask
The subnet mask, in like manner as the IP address and gateway,
is comprised of four octets. Set the gateway by entering the four
octets, one at a time.
1. Press key 3 to select line 3. Rotate the knob until line 3
appears as follows (line 4 may differ):
-----SETTINGS-----
Type: TCP/IP
> Option: NM_Oct_1 <
Status: 0
This prepares the 1256 to set the first octet
(eight bits) of the sub-net mask.
2. Select line 4 and rotate the knob until line 4 displays the first
octet of your desired sub-net mask. Then press key 4 again to
confirm.
3. Proceed with the remaining octets of the sub-net mask until all
four are set.
Re-enabling TCP/IP Communications
After setting the address, gateway, and net mask, you must re-
enable TCP/IP communications before the 1256 can use the
Ethernet interface:
1. Ensure that the display shows the “SETTINGS\Remote:
