Each Page (Module) handles 4 receive and 2 transmit channels, is controlled by
its own processor and works independently of the other modules. All 24 channels
may be run simultaneously although you may only access one Page (six channels)
at a time. The manual describes the functionality of a single Page; all Pages work
in an identical manner.
To determine if a module is installed and ready to operate after a power-up or a
software reset:
1.
Check the Module ID register (test for value = E429 H).
2.
Check the Module Status register (See
Module Status Register,
page 2-8)
The module is installed and ready when both registers contain the correct values
(as written above). For software reset operations, set these values to 0
immediately prior to writing to the Board Software Reset register.
