BDS Binary Data Structure

To transfer binary data in a single data segment, convey a critical filter for transmission and allow identification of the end of the data segment through a count; there is no identification of the internal structure of the binary data in this segment

Position: BDS-01 · Element: 1570 · Name: Filter ID Code · Type: Identifier (ID) · Requirement: Mandatory · Min: 3 · Max: 3 · Repeat: 1

Code specifying the type of filter used to convert data code values

Position: BDS-02 · Element: 784 · Name: Length of Binary Data · Type: Numeric (N0) · Requirement: Mandatory · Min: 1 · Max: 15 · Repeat: 1

The length in integral octets of the binary data

BDS02 is the length of the data in BDS03 after application of the filter indicated by BDS01. For example, a 1000 byte binary file that has been filtered using Base 64 encoding (value 'B64' in BDS01) will have a value of 1336 in the BDS02.

Position: BDS-03 · Element: 785 · Name: Binary Data · Type: Binary (B) · Requirement: Mandatory · Min: 1 · Max: ∞ · Repeat: 1

A string of octets which can assume any binary pattern from hexadecimal 00 to FF. Note: The maximum length is dependent upon the maximum data value that can be entered in DE 784, which value is 999,999,999,999,999.
