int WINAPI SelfTest (int Card)
DESCRIPTION
The
SB3621X
card has a self-test feature. By setting a register to 1’s, the card will go into
Self-Test mode, and all angles should read 45 degrees. If any channel does not display 45
degrees (+/- 1 degree), that channel does not pass. If all channels fail, a 0x3F is returned. If
only channel 0 fails, a 0x20 is returned. If a 0x99 is returned, the card was not initialized,
and therefore the Self-Test was not performed.
INPUT DATA
Card = an integer between 0 and 7 for the card of interest. The card number is set in
MOTION FEEDBACK BOARD MANAGER.
RETURNED DATA
This routine returns the Hex equivalent of the channels that fail as an integer. The “0” bit is
the most significant bit, and the 6
th
bit is the least significant bit.

0 x 99 is returned if the card did not initialize.
0 x 20 = Ch 0 fails
0 x 10 = Ch 1 fails
0 x 08 = Ch 2 fails
0 x 04 = Ch 3 fails
0 x 02 = Ch 4 fails
0 x 01 = Ch 5 fails
0 x 3F = all channels on the card failed.
0 x 00 = all the channels passed the initialization of the card.
