Translation FormatsUniSite-xpi User Manual 6-9The 5-Level BNPF Format, Codes 08 or 09Except for the start and end codes, the same character set andspecifications are used for the ASCII-BNPF and 5-level BNPF formats.Data for input to the programmer are punched on 5-hole Telex papertapes to be read by any paper tape reader that has an adjustable tapeguide. The reader reads the tape as it would an 8-level tape, recording the5 holes that are on the tape as 5 bits of data. The 3 most significant bits arerecorded as if they were holes on an 8-level tape. Tape generated from atelex machine using this format can be input directly to a serial papertape reader interfaced to the programmer. the programmer’s softwareconverts the resulting 8-bit codes into valid data for entry in RAM.The start code for the format is a left parenthesis, (Figs K on a telexmachine), and the end code is a right parenthesis, (Figs L on a telexmachine). The 5-level BNPF format does not have addresses.Note: Data without a start or end code may be input to or output from theprogrammer by use of the alternate data translation format code, 09. Thisformat accepts an abort character (10 hex) to abort the transmission.
