DA11 ~ DA0

Analog to digital data

DA0

The least significant bit (LSB) of the D/A data

DA11

The most significant bit (MSB)

When you write data to D/A channels, write the low byte first. The low byte is temporarily held by a register in the D/A and not released to the output. After you write the high byte, the low byte and high byte are added and passed to the D/A converter. This double buffering process protects the D/A data integrity through a single step update.

The PCi-1718 cards provide a precision fixed internal -5 V or -10 V refer- ence, selectable by means of Jumper JP10. This reference voltage is available at connector CN3 pin 11. If you use this voltage as the D/A ref- erence input, the D/A output range is either 0 to +5 V or 0 to +10 V. You can also use an external DC or AC source as the D/A reference input. In this case, the maximum reference input voltage is ±10 V, and the maxi- mum D/A output ranges are 0 to +10 V or 0 to -10 V.

Connector CN3 supports all D/A signal connections. Chapter 3 gives con- nector pin assignments and a wiring diagram for D/A signal connections.
