6. I/O MAP

Ruby-MM-1612 occupies 8 consecutive 8-bit locations in I/O space. For example, the default base address is 300 Hex (768 Decimal); in this case the board occupies addresses 300 - 307 (768 - 775). The first 2 locations are used individually for each analog output channel. Since analog output data is 12 bits wide, it is broken into two bytes. The first byte contains the 8 least significant bits (called the LSB) of the D/A data, and the 4 lowest bits of the second byte contain the 4 most significant bits (called the MSB) of the D/A data. The 4 highest bits of the second byte are not used.

The DACs are updated all at once when Base or Base+1 is read. The value read from these locations is not predictable and not meaningful. Only the act of reading from the board is required to perform the update.

Reset information:

A system hardware reset will also reset the board.

During a reset, the following occurs:

∙All analog outputs are set to mid-scale (0V for bipolar ranges and 1/2 full-scale for unipolar ranges).

∙The external trigger register is set to 0, disabling external trigger.

∙All digital I/O lines are set to input mode.

The next chapter describes all registers on the board. You should familiarize yourself with these registers in order to get a complete understanding of the board’s operation.
