Counter input applications
To set the module to frequency mode set the configuration code to 50 in the Set module configuration
command
$AAB0 to set input mode 0
$AA1H(data) and $AA1L(data)
$AAB1 to set input mode 1
$AAB2 to set input mode 2
$AA1H(data) and $AA1L(data)
$AAB3 to set input mode 3
$AA1H(data) and $AA1L(data)
Note:
The threshold voltage value commands $AA1H(data) and $AA1L(data) are effective for non-isolated inputs
only.
