So far, there have been four sets of errata for this document.
If you prefer, these are available as printable Microsoft Word documents, at www.romilly.co.uk/errata1.doc, www.romilly.co.uk/errata2.doc, www.romilly.co.uk/errata3.doc and www.romilly.co.uk/errata4.doc.
If you have a copy of my earlier editions, please note, there has been some confusion about the size limit for the HART data field. In early printings, the booklet several times mentions 25 bytes, but this must not be regarded as a specified absolute limit. See the HART data field for more information on this.
Editions printed between February 2002 and February 2004 may contain an error in figure 3-4. More information ...
