Each Flex or Integra module has 60 words of address space. 30 Input or Read

Horizontal and Vertical.

With Horizontal addressing the adapter address the first input and output word

for each module incrementally. 40001 for module 0, 40002 for module 1 and so

Vertical addressing increments the words for each module. For example, the

vertical read words for slot 0 start with 41001 and increment to 41015.
