24. Appendix 7: M4501 DSD Module

24.1. Overview

The M4501 DSD module provides alibi memory along with custom string support.

The information in this appendix applies only to indicators fitted with this module.

24.2. Writing records

A record will be stored in the DSD whenever a traceable weight is generated, A

traceable weight is only generated when a print of type RECORD or DOCKET

occurs, and only for TOTAL values of NONE or ADD. For more information on print

setup see sections 12.7 PRINT (Printouts)on page 74 and 16 Printing on page 100.

The DSD will also be written when a print occurs in alibi mode.

If a custom string is set then it will be stored along with the traceable weight. The

custom string accepts all print tokens. For more information on the custom string

and auto clear settings see section 12.2.6 DSD.HW on page 62.

24.3. Reading records

The records can be viewed in alibi mode or read through the communications

interface. For more information on viewing DSD records in alibi mode see section

5.14 Alibi on page 34. View400 can be used to retrieve the records from the

instrument or you can manually send communications commands to the instrument.

For a list of registers relating to reading DSD record via the comms interface see

section 20 Appendix 3: Communications Registers on page 123.

The reply to a DSD record read command will look like the following example:

81108295:1,2009/08/04,11:12:24, 2000,kg,GROSS, 0,kg,TARE,

4410,lb,13,p

This response is comma separated and contains the following data:

Response header: record ID, date, time, weight, units, gross/net, tare weight, tare

units, tare/P.tare., alternate weight, alternate units, piece count, piece units, custom

string

If the custom string DSD.STR: \BA\D7,\C9 is set then the reply will be:
