displays the current Slot Data Length in milliseconds and bytes for the remotes
in the group, and represents the amount of data that can be transmitted or

that group. This is the amount of time that the remote is provided to send data in
the cycle.
To change this setting, enter B at the command prompt to display the dialog
shown in figure 3-16.

Nominal Data Length

This menu item, which appears for Dynamic Slot Hub type, displays the Nomi-
nal slot Data Length in milliseconds and bytes for the remotes in the group,

that group. This is the amount of time that the remote is provided to send data in
the cycle.
