Configuration
The following switches must be correctly set to ensure proper operation. Refer to
Figure 1–1 for their physical locations.
Each functional module in a VXIbus System must be assigned a unique logical
address, from 1 to decimal 255 (hexadecimal FF). The base VMEbus address of
the Option 01 is set to a value between hexadecimal C0 (C000
16
) and hexadeci-
mal FF (FFC0
16
) by two hexadecimal rotary switches. Align the desired switch
position with the arrow on the module shield.
The physical address of the instrument is on a 64 byte boundary. If the Logical
Address switch representing the most significant digit (LA–HI) of the logical
address is set to position X and the switch representing the least significant digit
(LA–LO) of the logical address is set to position Y, then the base physical
address of the Option 01 will be [(40
