System Overview Guide
The NPS/IPS can be set up to receive data from the IBM host in
one of two ways:
one of two ways:
•
Through a bus and tag channel connection.
NOTE: If your system will be channel-attached, the printer
controller requires an additional component—either a
channel interface board and channel cable connector box, or
a Host Channel Unit (HCU) that serves as an interface
between the IBM host and the printer controller.

•
Through a Token Ring or Ethernet interface using TCP/IP.
NOTE: Your system supports only one other connectivity
option in addition to Ethernet. For example, Ethernet and
channel connection or Ethernet and Token Ring.

NOTE: A transmission rate of at least 16 megabits per
second should be used with a Token Ring interface. (Overall
performance depends on network traffic and job density.)
