I.8 Alarm Option
This option allows controlling the low and high limits
of the output (See Figure 5.). The output level is set
when the output tries to exceed the programmed
limits. Five bytes are reserved for this option. The
first byte is the low trigger limit and the second the
low output. The third and fourth bytes are used for
the high limit and the output. The fifth byte is the
alarm control, used to select the alarm input. The
different
levels
are
programmed
as
eight
bit
numbers. These correspond to the 8 upper bits of the
10 bit signal measurement. When the alarm mode is
not used, all of the data is 0. The control code is
coded as shown in Table 7. The six possible signals
are listed below and are encoded on the 4 MSB’s of
byte 31 of the EEPROM.
IO1 & IO2
IO1 and IO2 are used in the alarm and level steering
modes. For custom firmware, they can be used for a
digital input, an analog input, or a digital output.
