XEROX 4050/4090/4450/4650 LPS PRODUCT REFERENCE

The 4050/4090/4450/4650 Laser Printing Systems (LPS) can be connected in several environments such as IBM mainframes, DEC minicomputers, and PC Local Area Networks (LANs). This chapter discusses interface connections and provides a visual overview of typical configurations within these environments.

Several optional interfaces are available for use with the LPS.

Each interface offers different connection options.

You use the online interface for all IBM systems which support the channel-attached 3811/3211 and 4245 interface. The online channel interface receives input directly from the host computer system.

You can use the offline interface as an alternative to, or in addition to, an online system. The offline interface connects any

9-track or 18-track magnetic tape which conforms to one of the following formats:

• American National Standards Institute (ANSI)

• Burroughs format MCP 2500 through 4700, and 6700

• Control Data Communications (CDC) external format

• Digital Equipment Corporation (DEC) format RSX-11

• Honeywell format OS 220/2000 and OS 600/6000 series

• IBM formats OS/VS/370, OS/360, DOS/VS/370, or DOS

360/370

• ICL format 2900 VME/B

• Interpress on tape

• NCR format Century-B1

• Sperry/Univac Series 70 format 1100-OS standard files

• Tape input codes ASCII, Binary Coded Decimal (BCD), and

EBCDIC

• Univac tapes format SDF.

NETWORK CONNECTIVITY

OEM

Reference

You use the OEM interface for System Network Architecture and

Synchronous Data Link Control (SNA and SDLC) protocol and for

Binary Synchronous Communications (BSC) protocol. The 871-

CM and the LPS resident OEM interface work together to allow

ASCII and EBCDIC data transmission to the LPS, allowing the LPS to print jobs from a remote IBM-compatible host computer system. The 871-CM uses a telephone modem to eliminate the need for a channel-attached extender unit.

Refer to the Xerox 4050/4090/4450/4650 LPS System

Administration Guide and to the Xerox 871-CM System Guide for more information on SNA, SDLC, and BSC communications.

DEC

You use the DEC interface for communication in VAX/VMS DEC

Data Communications Message Protocol (DDCMP) environments. This interface allows communication between a

DEC VAX/VMS system and an LPS through cable or modem connections, using Host Interface Processor (HIP) tasks. The

DEC interface supports all UNIBUS, VAX-BI, or Q-Bus based DEC processors.

Ethernet

You use the Ethernet interface for devices connected to the network. Ethernet is the Xerox Local Area Network (LAN) which allows data to be transmitted by cable from one device to another. Using the Ethernet, your LPS can receive and print documents from other network devices such as the following:

• Ethernet workstations, such as the Xerox 6085 can transfer

Interpress files to the LPS and can invoke LPS-stored forms and graphics for printing.

• Ethernet graphic scanners, such as the 7650 Pro Imager and the 150 Graphic Input Station (GIS), can transfer scanned graphic data, including line art and continuous tone images, to the LPS. The LPS must have GHO/GVG to receive digitized graphics.

Make sure you select both the communications interface and the

Ethernet interface at system generation if you are using Ethernet communications.

IBM and compatible mainframes

IBM and IBM-compatible mainframes can be connected to an LPS through an online direct interface, a remote interface, or a network.

Online direct interface

The IBM direct interface, also called a channel interface, uses the

IBM 3211 or 4245 protocols as shown in figure 4-1.

Barr/SNA Communication Module

Datastreams Application software used with IBM and IBM-compatible hosts in an online connection generally produces printer output in line printer or LCDS (Xerox metacode) datastreams. For those products that produce other datastreams, such as AFP, translators are available that convert the output to LCDS. None of these formats require further conversion, so a front end processor is not necessary.

To connect an IBM or IBM compatible mainframe remotely, an

OEM interface and Barr/SNA Bisynchronous Communication

Module are required. In this configuration, the LPS can support

SNA/SDLC or bisynchronous protocol environments as shown in figure 4-2.

Figure 4-2.

Datastreams Application software for a mainframe in an IBM remote connection usually outputs line printer or LCDS datastreams or bitmapped .IMG files; these do not require further conversion.

NETWORK CONNECTIVITY

Network interface

Ethernet LAN

An IBM or IBM-compatible mainframe may be connected to an

LPS through a LAN as shown in figure 4-3.

This configuration requires a front end processor, such as Entire

FIBRE 400/600, that converts the Ethernet TCP/IP protocol to an

Ethernet XNS protocol.

Other LAN If you are using a network interface other than Ethernet, such as token ring, you need a third-party gateway to convert your network protocol to Ethernet TCP/IP protocol. You then need a front end processor to convert the TCP/IP protocol into XNS on

Ethernet.

Front end processor

Datastreams In this configuration, application output is generally in PostScript.

PostScript must be converted to a datastream format the printer understands. The front end processor converts PostScript datastreams to .IMG files. The front end is also needed to convert TCP/IP to XNS.

DEC VAX and MicroVAX mainframes

An LPS connected to either a DEC VAX or MicroVAX system in the VMS environment can be configured for either a communications or network interface. The communications interface may be either local or remote. See figure 4-4 for a DEC

SPMF-VMS online interface.

Reference

A DEC VAX/VMS platform can use the XPMF-VMS option to connect to an LPS through a DEC communications interface. For a local connection, the Xerox-supplied modem eliminator may be used to provide a point-to-point communications link. You can use modems to create a remote connection.

The XPMF software is installed on the host to generate DJDEs from the DEC DCL PRINT command and accommodate the physical linkage using the DEC DDCMP protocol.

Refer to the XPMF-VMS product literature for more details on this interface option.

Network interface

Datastreams In this configuration, application output is in ASCII text plus DJDE format. No datastream conversion is required. A front end processor is not applicable.

A DEC VAX/VMS mainframe is connected to an LPS through an

Ethernet LAN as shown in figure 4-5. Multiple solutions are present for this environment.

SPUR System 534: The SPUR System 534, available from the

Xerox Connection, provides network connection. It should be noted that any VAX system utilizing TCP/IP in the VMS environment requires the DEC TCP/IP Services for OpenVMS (or equivalent), if it is not already present.

Xerox XNS 5.0 for VMS: If the Xerox XNS for 5.0 for the VMS software package is used, no communications protocol conversion is required. If XNS 5.0 is not used, then a bridge that provides connectivity between the VAX Ethernet TCP/IP or

DECnet protocol and the selected Xerox interface is required.

Note: XNS 5.0 for VMS is limited to text printing only.

Entire 400/600: The Entire FIBRE 400/600 front end processor serves as a bridge for TCP/IP.

FunAsset TNxxxx: In Rank Xerox, the FunAsset TNxxxx series provides network connectivity through a DECserver 250, or equivalent. The FunAsset interface is also capable of providing a local or remote communications interface.

PCs can be connected to an LPS with a network connection

(Ethernet or other) or in an online configuration using third-party interface hardware and software.

Ethernet interface

Communication protocols

A PC may be connected to an LPS through an Ethernet Local

Area Network.

Each PC on the Ethernet LAN requires its own Ethernet card. The

Ethernet TCP/IP print jobs are converted to Ethernet XNS print jobs by the Entire FIBRE 400/600 front end.

A combination of Ethernet card and the Xerox XNS PC Plus 2.0

software package allows a PC to produce XNS protocol on

Ethernet. This configuration does not require a front end if it is used with software applications that produce LCDS or Interpress datastreams.

Datastreams Datastreams are handled the same as described with the Ethernet interface above.

PC online interface

There is a third-party interface that allows a PC to be connected directly to an LPS in an online configuration. Contact The Xerox

Connection or your Xerox representative for connectivity and application software information for this configuration.

Macintosh workstations

Macintosh PCs are generally connected to an AppleTalk network.

They may also be configured to connect to Ethernet. The type of LAN you use in your facility depends on the number of

Macintosh PCs you want to connect to the LPS. If you want only a few of your Macintosh PCs to be capable of sending documents to the LPS, then an Ethernet connection may be more cost effective. If you have a large number of Macintosh

PCs in your facility and you require all of them to be capable of transmitting to the printer, it is less expensive to use AppleTalk and convert to Ethernet through a communication module.

AppleTalk network interface

Communication protocols

The standard Macintosh LAN configuration is through AppleTalk, as shown in figure 4-9. Most networked Macintosh PCs use

AppleTalk to communicate with a printer.

The LPS does not accept input directly from an AppleTalk network. AppleTalk must first be converted to Ethernet, so a communication module such as Shiva’s FASTPATH is necessary.

FASTPATH converts AppleTalk communication protocols into

TCP/IP protocol on Ethernet. The TCP/IP print jobs can then be converted into XNS print jobs by a front end processor.

Communication protocols

Each Macintosh connected to the network must have its own

Ethernet card. One or a few Ethernet cards are less expensive than the communication module needed to convert AppleTalk to

Ethernet.

You can use an Ethernet configuration to restrict printer accessibility to a small number of Macintosh PCs at your facility simply by installing Ethernet cards in only those few PCs you wish to have connected to the printer.

With the Ethernet card in place, output is in TCP/IP on Ethernet.

A front end processor is then required to connect TCP/IP to XNS.

Other workstations

Ethernet interface

Other network interfaces

Workstations other than the IBM PC, Macintosh, and Sun may also be connected to the LPS through a LAN. The connectivity products needed depend upon the type of network used, the communication protocols used on that network, and the datastreams generated by the application software in use.

Several types of workstations now have Ethernet compatibility.

An Ethernet card is required for each compatible workstation you wish to connect to the LPS.

If the workstation uses TCP/IP protocol on Ethernet, a front end processor is required to connect TCP/IP to XNS. A front end processor is also necessary if the application software used produces a datastream other than Interpress or LCDS.

Refer to Figure 4-7 for an example of an Ethernet LAN interface.

If your workstations use a LAN other than Ethernet, a communication module is necessary to convert to Ethernet. This conversion usually produces TCP/IP on Ethernet rather than XNS on Ethernet.

A bridge or front end processor is required to convert TCP/IP to

XNS. The front end processor is also necessary if the application software used produces a datastream other than Interpress or

LCDS.

Refer to Figure 4-8 for an example of an interface involving a non-Ethernet LAN.
