6287 ALLY PLUS User’s Manual

Coax Host Considerations

The ALLY PLUS connects directly to the establishment controller through an IBM category A device adapter. The port designation for the ALLY PLUS must be configured for a category A device, not as the system printer.

The ALLY PLUS must be defined to the system as a 3287 printer with a maximum 4K physical buffer size (and/or with other features required by the system and supported by the ALLY PLUS).

The host parameters in Option Group #50 must match what the host expects on the channel to which the ALLY PLUS is attached. The defaults are as follows:

•4K physical buffer size

•3440 bytes/buffer logical buffer size

If using SCS data streams, the ALLY PLUS must be defined to the host as an SNA type 1 logical unit (LU1).

If using DSC data streams, the ALLY PLUS must be defined to the host as a type 3 logical unit (LU3).

If using VTAM or another Network Control Program, the 3174, 3274 or 3276 control unit to which the ALLY PLUS is attached must be defined as a type 2 physical unit.

Power-On Reset

The ALLY PLUS responds to a poll with a POR sequence if no coax traffic has been detected for five seconds, so the host will know that it is “ready,” even after catastrophic circumstances. For instance, if power to the host or controller fails, the controller, when it resumes operation, might otherwise consider the ALLY PLUS inactive. In other cases, systems are put to “sleep” when not in use. This feature ensures that communication with the host will resume when the host is ready.

Printer/Controller Configuration

The ALLY PLUS provides all of the necessary functions normally provided by the operator switches of an IBM 3287. However, practical application of industry-standard printers does not allow a one-to-one correspondence in functions. It is accordingly expected that any particular printer/controller configuration will be a subset of the IBM 3287 function set.

This level of efficiency ensures that high-volume printing tasks are completed quickly, allowing users to focus on other essential aspects of their work. The printer supports a maximum print resolution of 1200 x 2400 dpi, delivering sharp text and vibrant images for a wide range of document types.

The Xerox 6287 is designed with an advanced color printing technology, incorporating Xerox’s patented EA (Emulsion Aggregate) toner. EA toner offers high-quality color reproduction while minimizing environmental impact, making the printer a sustainable choice for organizations looking to reduce their carbon footprint.

In addition to traditional printing capabilities, the Xerox 6287 facilitates advanced scanning features. Users can digitize documents with ease, and the printer provides options for both simplex and duplex scanning. The scanning resolution can reach up to 600 x 600 dpi, ensuring that even the finest details are captured accurately.

Another notable characteristic of the Xerox 6287 is its user-friendly interface. The printer comes equipped with a large color touchscreen display that simplifies navigation through various functions and settings. This intuitive interface enhances user experience and minimizes the learning curve for new operators.

Connectivity options are abundant with the Xerox 6287. It supports USB, Ethernet, and wireless connections, making it easy to integrate into existing network infrastructures. Users can also leverage mobile printing capabilities, allowing them to print documents directly from their smartphones or tablets via apps such as Apple AirPrint and Google Cloud Print.

Security is a top priority for the Xerox 6287, which features a range of built-in security features to protect sensitive information. These include secure print, user authentication, and data encryption, ensuring that documents remain secure throughout their lifecycle.

With its combination of efficiency, quality, and advanced features, the Xerox 6287 stands out as a premier choice for businesses looking to enhance their document management processes while maintaining a sustainable and secure printing environment.
