Xerox 4090, 4050 manual Printing system channel-attached configuration

IPDS printing environment

The NPS/IPS can be set up to receive data from the IBM host in 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.)
