token hold time is multiplied by the number you enter. For example, if
you enter 2, the token hold time will double. You may want to increase
the token hold time at the node if, for example, that node typically has
more messages to send than other nodes.
The Set Node Mode Menu
When you select option 3 from the Data Highway II Interface menu, you
receive the Set Node Mode menu. This menu allows you to change the
mode of the KP3:

INRING
the KP3 is fully operational.
ONLINE the KP3 allows requests for immediate data and ``time-critical
writes with no reply". The KP3 will not initiate any messages, nor
reply to any.
OFFLINE the KP3 will not initiate or respond to any messages.
The Input File List Menu
When you select option 4 from the Data Highway II Interface menu, you
receive the Input File List menu:
KP3 1, INPUT FILE LIST
ENTER STATION AND INPUT FILE >
Use this to tell the KP3 which input file to read data from or write data to
when it receives a message from a device using PLC–2–style addressing
(e.g., a 1779–KP2, –KFL, or, –KFM interface module or another KP3
module).
