EVFU 6–11
Clearing EVFU Memory
Use one of the three following actions to clear (reset) the EVFU Memory.
• Send only the Start Load and End Load codes (no channel assignment
data).
• Send an odd number of EVFU characters (channel assignment data)
(detected after the End Load code is received). Remember, two data
bytes are required per line.
• Send a second Start Load code, which will result in reinitializing the
EVFU memory routine.
