EI
FUNCTION: Enable Interrupts
DESCRIPTION:
The EI command enables an ISA, PC/104 or PCI bus interrupt on conditions such as motion
complete or excess positional error. The conditions are selected by the parameter m
where m is the bit mask for the selected conditions as shown below. Prior to using the EI
command, one IRQ line must be jumpered on the DMC-141X. An interrupt service
routine must also be incorporated in your host program. See Chapter 4 in the product
manual for details.
