Introduction The DATA and SETup commands are S Y ST e m comm a n d s that allow you to se n d a nd receive block data between the HP 165 54A, HP 16 555A, o r HP 1 6555D and a contro ller.

Data Fo rmat To understand the format of the data within the block data, t here are four important things to k eep in mind. • Data is sent to the controll er in b inary form. • Each byt e, as describ ed in this chapter, co ntains 8 b i ts . • The first bit of each b yte is t he MSB (mo st significant bit). • Byte descripti ons are printed i[...]

Acquisition Data Descrip t ion The acquisi t ion dat a sectio n consists o f a variable number o f byt es depending on the number of cards in the configuration, the acqui s ition mode , and the state tag set ting. The data i s grouped in rows of bytes with one sample from each pod in a single row. T he width of the row is based on the number of car[...]

The depth of the data array is equal to the pod with the greate st numb er of rows of valid data. If a pod has fe wer rows o f valid data t han the dat a array, unused rows will contain invalid data that should be igno red. The clock pod contains dat a mapped according to the clock designator and the board (se e below) . Unused clock l i nes should[...]
