Figure 2. Pressure Reading Control
Shaded blocks represent command codes executed in the microprocessor
• Single or Continuous
• ASCII or Binary
Pressure Values
P1, P2, P3, P4
Pressure
if c = 0 then no output
if c = 1 - 255 then add 'c' wait
cycles between inputs
IC = c
(IC=0 factory default)
Idle Count
if r = 0 then output every input
if r = 1 - 10 then skip r x 100
identical readings
RR = r
(RR=00 factory default)
Reading Rate
if d = A then output every input
if d = U then output only changes
if p = X then no watchdog timer
if p = W then use watchdog timer
For binary format mode:
if m = N then no checksum
if m = C then use checksum
if n = S then use standard format
if n = E then use extended format
OP
= d m n p
(OP=ANEX factory default)
