9T122-08 Module Specific Information
Screen Lockout Time
Contains the maximum number of minutes that the Local Management
application will display a moduleÕs screen while pending input or action from a
user. For example, if you enter 5 in this Þeld, users will have up to Þve minutes to
respond in some fashion to each of the speciÞed moduleÕs Local Management
screens. In our example, after Þve minutes of ÒidlenessÓ (no input or action), the
Local Management application terminates the session on the selected module and
the Slot Selection Screen reappears. To enter a new lockout time, highlight the
Þeld and enter a number. The
default lockout time is 15 minutes. The range is 1 -
30 minutes.
Host IP Address
Contains the Internet Protocol address currently assigned to the selected module.
Set this Þeld according to your network requirements. Highlight the Host IP
Address Þeld and enter the desired IP address using dotted decimal notation (4
decimal values between 1 and 255 separated by periods) as follows:
255.255.255.255
(255 is the maximum number that you can enter in any of the four segments.
Default = 0.0.0.0 .) This address can be used by any of the system interfaces on the
module.
Subnet Mask
Contains the subnet mask for the selected module. A subnet mask Òmasks outÓ
the network bits of the IP address by setting the bits in the mask to 1 when the
network treats the corresponding bits in the IP address as part of the network or
subnetwork address, or to 0 if the corresponding bit identiÞes the host. The
default subnet mask uses the Þrst two portions of the IP address to identify the
network id, leaving the rest of the IP address to identify speciÞc nodes. To enter a
new subnet mask, highlight the Þeld and enter a new value using dotted decimal
notation (4 decimal values between 1 and 255 separated by periods) as follows:
255.255.255.255
(The Subnet Mask Þeld defaults to the natural mask value, based on the IP
Address that you entered for the device.)
Default Gateway
Contains the IP Address of the device to which all packets addressed to an
unknown network or host are sent. If you do not conÞgure a Default Gateway,
any packets that are addressed to an unknown network or host will be dropped.
This Þeld is not deÞned until you enter an appropriate value using dotted
decimal notation (4 decimal values between 1 and 255 separated by periods).
