6287 ULTRA User’s Manual

Trigger 1 + Count Byte PTM

In the one-trigger mode, the user selects the trigger using any single character that is not commonly found in the printable data stream (see Section 5 — Configuration Options and refer to Options 32 and 34 for information on restrictions on the selection of triggers). The default trigger is a cent sign (¢).

The one-trigger mode requires a count byte following the trigger that tells the ULTRA how many pairs of additional characters will follow the count byte (the count byte is not included in the count).

To send 1 ASCII escape character requires five input characters — the trigger (¢), the hexadecimal count byte (01h) and the hexadecimal ASCII escape character (1Bh):

¢011B

To send the Xerox 4045 reset sequence requires nine characters — the trigger (¢), the hexadecimal count byte (03h) and the hexadecimal reset sequence (1Bh, 2Bh and 58h):

¢031B2B58

MD-Laser Pseudo Transparency

The ULTRA is capable of supporting “continuous escape,” a form of pseudo transparency offered in Maersk Data products. It is triggered by SCS Trigger 1 (see Option #34) followed by C2h. If Option #55 is set to “Yes,” when this sequence is detected in the data stream, the ULTRA will pass the subsequent hexadecimal pairs of data to the printer without translation until terminated when SCS Trigger 1 is encountered again. Spaces and control codes in between the Trigger 1 characters are ignored.

When in use, the ULTRA begins checking for valid pairs of hexadecimal characters. When the ULTRA detects an asterisk, it combines the two bytes prior to the asterisk to form a count byte, and it combines the two bytes after the asterisk to form a repeat byte. The ULTRA then sends out the repeat byte to the printer the number of times indicated by the count byte. This provides some compression of graphic data.
