CONFIGURATION OPTIONS

25 — Centronics or Dataproducts Parallel

This option determines whether the ULTRA implements a (A) Centronics or (B) Dataproducts parallel interface. The default value is (A). Users with older Dataproducts printers using their proprietary DB interface must also provide AGILE with the pin-out chart, so a custom cable can be made.

26 — Intervention Required

The host should be informed when a problem is detected at the printer or the protocol converter. This option determines whether or not the ULTRA transmits an Intervention Required message to the coax host when a printer fault (e.g., out of paper) is reported by a parallel-attached printer. The default value is “Yes.”

In the event of a parallel printer error, the PRINTER READY light on the ULTRA front panel will go out, and the CHECK light will go on.

Coax host systems react differently to Intervention Required. In some cases, the printer may be disabled until a command is sent to reacquire the printer. After the error condition is cleared, the ULTRA informs the system, and printing can restart either at page 1, from the top of the page where the intervention occurred, or from where the printing stopped.

If the handling of intervention is causing a problem, the best solution is to change the way in which the system responds to it. For example, since laser printers buffer all data received, it is not necessary to retransmit any data from a previous page. The system should be configured to halt when an Intervention Required is received, so when the error condition is cleared, the system will continue transmitting from where it left off.

Intervention Required can be disabled to prevent the error message from being sent, or a delay can be set to give the user time to fix the problem.

27 — Intervention Required Delay

This option determines how many minutes the ULTRA will wait after receiving a parallel printer fault indication before sending an Intervention Required message to the coax host (if Option #26 is set to “Yes”). If the problem is minor, such as a paper jam, the user may correct the problem before it needs to be reported. The user may select any value between 0 (immediate) and 255. The default value is 10 minutes.

28 — Reserved

This option is reserved.
