PRODUCT OVERVIEW
Host connectivity options
1-2
The DocuPrint 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 called a Host
Channel Unit (HCU), which interfaces between the IBM host and
the IPS controller.
•
Through a Token Ring or Ethernet interface using TCP/IP (the
HCU is not used).
Note: A transmission rate of at least 16 megabits per second
should be used with a Token Ring interface on the IPS. (Overall
performance depends on network traffic and job density.)
•
The software supports Token Ring over TCP/IP, and
Ethernet over TCP/IP, with the exception of VM and VSE
platforms.
•
Of the other platforms that support TCP/IP, only the RS/
6000 supports 100 Mb Ethernet connectivity.
