INTRODUCTION

General Information

The AGILE 6287 ALLY PLUS is a high-speed protocol converter that

enables industry-standard ASCII and EBCDIC printers to be attached to an

IBM 3270-type mainframe controller. It also allows up to three alternate

hosts to share the attached printer(s).
The coax port allows a standard IBM RG62 A/U cable to connect to an

IBM 3174 or 3274 establishment controller (EC) with a category A device

adapter, a 3276 terminal controller unit, or an IBM CPU with a Display

Printer Adapter (DPA).
By using the ALLY PLUS, non-IBM impact and laser printers can replace

IBM 3287, 3289, 3262 and 4224 printers. Popular printers from Xerox,

Hewlett-Packard, Lexmark and other manufacturers are supported and

appear to the host as IBM printers.
The ALLY PLUS also may be attached to plotters, rasterizers, bar code

printers and other output devices that support parallel or serial interfacing,

although this manual will refer to the attached device as a printer.

Supported Printer Interfaces and Character Sets

The ALLY PLUS supports the following printer interfaces and character

sets:

• DB-25 Centronics parallel interface (IBM PC compatible)

• RJ-12 serial interface (to 115.2K baud)

• ASCII, EBCDIC or APL character sets

IBM Port

The ALLY PLUS connects directly to the IBM establishment controller, or

equivalent CPU with a Display Printer Adapter, through an IBM standard

coaxial cable.

Alternate Host Feature

The ALLY PLUS has been designed to support up to three alternate host

devices. This allows the mainframe and the alternate host(s) to share the

printer(s) without the necessity of an A/B switch.
