Pamux User’s Guide 123
USEFUL TIPS
• The microprocessor on the B6 constantly scans and converts analog channels, then transfers
input data to the dual-port RAM (if it has access). Output data is read by the processor from
the dual-port RAM. The value read is then converted to output information that analog
modules translate into voltages or currents.
• Polling one B6 continuously may not give the brain board’s processor much of a chance to
update the RAM. Remember, while you have access, the brain board’s processor cannot read
from or write to the RAM.
• It is OK to access more than one channel once you have access, but if you spend too much time
on one board, the data may no longer be fresh (for the reason stated above).
• After a power-up or reset condition, it is important to reconfigure the analog brain board by
writing to the configuration registers. The B6 brain board clears all dual-port RAM locations
upon a power-up or reset. Since the configuration register is a RAM location, it will also be
cleared.
