Online channel interface
The online channel interface receives input directly from a host
mainframe through a cable. All IBM and IBM-compatible systems
supporting the channel attached 3211 and 4245 protocols are
supported.
OEM interface
The Barr/SNA unit and the LPS-resident OEM interface work
together to permit ASCII and EBCDIC data transmission to the
LPS in SNA/SDLC and bisynchronous (BSC) protocol
environments. This allows the 4890 LPS to print jobs from a
remote IBM-compatible host computer.
The Barr/SNA is a PC-based communications module that acts as
a bridge between the communications protocol sent by the host
and the protocol used by the OEM interface.
Refer to the Xerox 4890 HighLight Color LPS Operator Guide for
more information on SNA/SDLC and bisynchronous
communications.
DEC XPMF-VMS interface
The Xerox Print Management Facility (XPMF)-VMS interface
enables communication between a DEC VAX/VMS system and the
4890 LPS through cable or modem connections, using the host
interface processor (HIP) task. All UNIBUS, VAX-BI, or Q-Bus-
based digital processors are supported.
Third-party interfaces
Third-party interface hardware and software is available to provide
online connectivity for many non-IBM compatible mainframes
and also for PC and PC-compatible workstations. Refer to the
“Third-party connectivity products” appendix for a list of some of
the third-party interfaces available.
