Compaq P5000 Series Ignore / DB8 Setup, Ignore Chars, Ignore ch#1, Ignore ch#2, Data Bit

Chapter 4 IGP/VGL Emulation

NOTE: When Barcode Errors is disabled, the IGP/VGL emulation will try to make the best use of invalid data by either truncating extra digits or adding zeros to the end of bar code data to meet minimum data length requirements for some bar codes. Not all errors will be corrected.

Ignore / DB8 Setup

Following are several options which define character filtering and data bit 8.

Ignore Chars

•Disable. Character filtering is not enabled.

•Char 1. Character 1 will be filtered. Select the option “Ignore ch#1” to specify character 1.

•Char 2. Character 2 will be filtered. Select the option “Ignore ch#2” to specify character 2.

•Char 1&2. Characters 1 & 2 will be filtered. Select the options “Ignore ch#1” and “Ignore ch#2” to specify values for these characters.

Ignore ch#1

Specifies character 1 for the character filtering option. Valid decimal values are from 0 through 255.

Ignore ch#2

Specifies character 2 for the character filtering option. Valid decimal values are from 0 through 255.

Data Bit 8

•Enable. The PI line is not passed directly from host to printer; all 8 bits are used for data bits, and characters in the hex 80-FF range can be accessed.

•Disable. When the host PI line is enabled, data bit 8 internally indicates PI line status. To use the PI line, disable data bit 8, and enable the Host PI configuration option (under the PI Control option, below).

NOTE: Data bit 8 is interpreted as either data bit 8 or PI signal, but never both. When enabled as data bit 8, data bit 8 has priority over the PI signal, and all data above hex 7F is used to access character data and not to interpret PI line data.

Conversely, when data bit 8 is disabled and the PI signal is used, data bit 8 of the data is reserved for use as the PI function, and you cannot access characters in the hex 80-FF range. Therefore, to access characters in the hex 80-FF range, data bit 8 must be enabled.
