Host Channel Unit (HCU)—channel-attached systems only

IPDS data stream

Installation Planning Guide
Your system may use a Host Channel Unit (HCU) for channel
connection to a host for IPDS printing.
The HCU handles all IPDS communications and handshaking
with PSF on the host when the system is receiving data over a
channel. It is not used when the system is printing data using
TCP/IP.
Figure 1-4. Host Channel Unit (HCU)
The front panel of the HCU provides a single-digit LED display
that enables you to monitor power-up and offline status, and
alerts you to error conditions.
The back panel of the HCU has a power switch and outlet, bus
and tag cable input and bypass connectors, and a dual serial
port.
NOTE: The customer is responsible for obtaining, stringing, and
maintenance of the bus and tag cables. The bus and tag cables
must be fully populated cable sets.
All IPDS resources (print data sets, page definitions, form
definitions, page segments, fonts, and overlays) that are
supported by the IBM 3825 and 3827 printers are supported by
the Xerox software. Additionally, the data towers that are
supported within the AFP environment by the IBM 3825 and IBM
3827 printers are fully supported by the software. Data towers
supported are:
• IM Image IMD1
• FOCA: Font Object Content Architecture
