Note: Only Analog1 to Analog6 are packed; the 16-bit Pulse

Counters are not.

Figure 26 shows the placement of various inputs on the

connectors.

Figure 26. A723 Connector Inputs

The RF level is linear and results from a table (which you can get

from Adcon as an ASCII file). The value of the battery can be

computed as follows:

The digibyte is essentially the reflection of several inputs or internal

status bits on the A723; its structure is described below:

For more details, refer to the user manual for the A723 device.

The A733 (addWAVE) Frames

The addWAVE currently implements only one frame type (37). The

A733 samples the analog values with 10-bit resolution and stores

them as 12-bit values. Also, the A733 contains built-in logic to

sample 12 different analog inputs, as well as four 16-bit pulse

counters—all in all, substantially more data. Due to the limited
