Driver Block Parameters

Board type -- Select the specific board type from the list provided.

Channel vector -- Enter a vector of numbers to specify the input channels. For example, use the first and third analog input (A/D) channels, enter

• [1 3]
  

The channel numbers can occur in any order. Number the channels beginning with 1 even if the board manufacturer numbers them beginning with 0. The maximum allowable channel number is 4, 8, 16, or 64 depending on the board type.

Gain vector -- Enter a vector of numbers to select the gains for each of the channels. Available gains vary depending on board type. MF PGL gains may be set to 1, 10, 100, or 1000. MF PGH gains may be set to 1, 2, 4, or 8. MF DG-option gains may be set to 1, 2, 5, or 10.

Mux settling time factor -- This vector must be the same length as the channel vector. It contains values of 0 or 1. If 1, the corresponding channel has a longer settling time. This is useful when using a high gain such as 100 or 1000.

Range -- Select the voltage range from the list provided. This applies to all channels.

Sample time -- Enter the base sample time or a multiple of the base sample time.

PCI Slot (-1:autosearch) -- Enter a number between -1 and n. If only one board of this type is physically present in the target PC, enter

• -1 
  

If two or more boards of this type are physically present in the target PC, enter the bus number and the PCI slot number of the board associated with this driver block. Use the format [BusNumber, SlotNumber]. To determine the bus number and the PCI slot number, type
