Analogic AIM - Analogic AIM board

Board

Analogic AIM12

General Description

This board comes in three configurations from the factory. The configurations are the AIM12-1/104, the AIM16-1/104, and the AIM16-2/104. The AIM16-1/104 and the AIM16-2/104 differ only in the time required to acquire each sample. The AIM12-1/104 acquires 4 fewer bits, but since the 12 bits are placed in the high 12 bits of the result word, the internal scaling factors are identical to those used with the AIM16. The output of the AIM12 changes in larger steps. Gain settings for the AIM12 are also different than for the AIM16.

When acquiring samples from multiple channels, the board is driven in its burst mode when the highest clock rate available for the board is used. The AIM12-1/104 can acquire all 16 channels in 160 microseconds.

The AIM12 hardware can acquire from 1 to 16 (single ended) channels at each sample time. These channels must be in a contiguous group, but can start with any channel number and end with any channel number that is greater than or equal to the start channel number. A single channel is acquired by setting both first channel and last channel to the same value.

The choice of unipolar or bipolar conversion range is made by placing jumpers in accordance with the hardware manual. The driver reads the hardware configuration and adjusts the integer to float conversion accordingly.

The xPC Target block library supports this board with these driver blocks:

• Analogic AIM12 Analog Input (A/D)

• Analogic AIM12 Digital Input

• Analogic AIM12 Digital Output
