Multi-4J/PCI VA2
c. Slew: Slew Rate Limit Ability
 10M: Not use Slew Rate Limit ability. Maximum communication speed
921.6Kbps in this mode.
 250K: Use Slew Rate Limit ability. Communication speed is limited under
250Kbps.
Slew Rate Limit reduces reflected waves emitting from ends of
communication cables and speeds up slew-rate driver that restrains EMP
electromagnetic waves thereby enabling communication with no data errors.
But communication speed is limited in this mode
