1.0 General

This standard defines the recommended multiplexer format for single channel data recording on small format (1/2”) media ( reference 6.17). This format is recognized as the Asynchronous Recorder Multiplexer Output Re-constructor (ARMOR). This format is software-reconfigurable for each data acquisition or reproduction. The ARMOR format configuration information is stored in a data structure called a “setup” that contains all the information necessary to define a particular record or play configuration. This appendix describes the format and content of the ARMOR setup.

1.1 Setup on Tape. When the ARMOR setup is written to tape, it is preceded by a preamble with a unique setup sync pattern that allows the identification of the setup. Three duplicate setup records, each with its own preamble, are written at the beginning of each recording. The format of the preamble is defined in Table L-1.

TABLE L-1. ARMOR SETUP PREAMBLE

FIELD	LENGTH	DESCRIPTION
SETUP SYNC	4 TAPE BLOCKS	THE SYNC PATTERN CONSISTS OF TWO BYTES. THE HIGH BYTE IS 0XE7; THE LOW BYTE IS 0X3D. THE SYNC PATTERN IS WRITTEN HIGH BYTE FIST. FOR THE DCRSI, A TAPE BLOCK IS A SINGLE SCAN (4356 BYTES). FOR THE VLDS, A TAPE BLOCK IS A PRINCIPLE BLOCK (65536 BYTES).
END OF SYNC	3 BYTES	THE THREE BYTES IMMEDIATELY FOLLOWING THE SYNC PATTERN ARE: 0X45, 0X4F, 0X53 (ASCII ‘E’, ‘O’, ‘S’ FOR “END OF SYNC”).

An ARMOR setup is divided into three sections: the header section, the channel section, and the trailer section. The overall organization of a setup is summarized in Table L-2.

2.1 Header Section The header section is the first 70 bytes of a setup. It contains information about the setup as a whole, including clock parameters, frame parameters, and the numbers of input and output channels (see Table L-3).

In Tables L-3 through L-12, fields noted with an asterisk (*) require user input per section 2.5.

2.3 Trailer Section. The trailer section contains the setup description and the checksum (see Table L-15). Early versions of the setup do not contain this information. The “Setup Keys” field in the header indicates the content of the trailer section.

TABLE L-15. TRAILER SECTION FORMAT

FIELD	BYTES	FORMAT	DESCRIPTION
SETUP DESCRIPTION	40	ASCII	DESCRIPTION OF THE SETUP
SAVED SCANLIST	VARIES	BINARY	NUMBER OF BYTES DEPENDS ON THE NUMBER OF CHANNELS BEING RECORDED.
CHECKSUM	4	BINARY	SUM OF ALL SETUP BYTES.

2.4 Saved Scan-list Structure. This is an array of enabled input channels that make up the calculated scan-list. Each element of the array is made up of two fields, an index field and a count field. The length of the index fields is one byte, and the length of the count field is two bytes.

The index field, which is 1-based, is determined by the position of the channel’s module in the ARMOR system. The first input channel found in the ARMOR system is assigned an index of 1, the next input channel is assigned a 2, and so on. The search for input modules starts at slot 1. Filler bytes are assigned an index value of 255.

The count field is the number of words/samples per frame that is assigned to that input channel.

2.5 Creating a Setup Block . Creating a Setup Block involves two steps. In the first step, the user creates an “input” setup block file as described below in this section. Most of the fields in the input setup block file are unspecified (filled with zeros). In the second step, the input setup block file is read by the ARMOR Compiler program that produces a new setup block file with all the unspecified fields initialized to the appropriate values. In other words, a setup block has two types of fields, user specified and compiler generated. Note that all compiler generated fields must be provided in the input setup block file and initialized with zeros prior to executing the ARMOR compiler program.

The rules presented in this section must be explicitly followed to create an ARMOR input setup block. Values for fields identified in the previous tables with an asterisk preceding the field name must be provided. In some cases the values for these required fields are constant and are specified in the tables above. In other cases, the user must provide the desired value. All fields with names not identified with asterisks must be initialized to binary zero. This includes both “unused” and “reserved” fields.

Only input channel information entries are required. Output channel information entries are ignored by the ARMOR Compiler program.

2.51 Header Section.

Setup Length	Count the total numbers of bytes in the created setup block and put the value here.
Setup Keys	Set bit 0 = 1 if the trailer contains a description. Leave other bits = 0.
Input Count	Enter the total number of input channel information entries, including both enabled and disabled entries.

2.5.2 Channel Section. PCM, Low Frequency (LF) Analog, and parallel input channel information entries must be included in the setup block in groups of four entries per type. High Frequency (HF) analog input channel information entries must be included in the setup block in groups of two entries per type. Time code /voice input channel information entries must be included in groups of three time code entries and one voice entry. Specifying an ASCII “N” in the enabled field must disable all unused input channel information entries. For each channel information entry group, the channel number field of the first entry in the group is 0 (zero), the second entry is 1, the third is 2, and the fourth is 3. For the time code /voice group, the time code entry channel number fields are 0, 1, and 2 respectively, while the voice entry channel number field is 3. HF analog entry channel number fields are 0 and 1 respectively.

Description fields are not required and are not specified below. However, it is advisable to include an ASCII description of each channel for future reference.

2.5.2.1 PCM Input Channels.

2.5.3 Trailer Section. The trailer section of the input setup block is not required. The user may include an ASCII text setup description in the trailer section by setting the setup keys bit 0 = 1 in the header section (see Section 2.5.1 above) and adding the setup description field only in the trailer section.

2.5.4 ARMOR Compiler Program . Operational instructions for the ARMOR compiler program are provided in the readme.txt file provided with the compiler (see Section 6.17.3.1).
