6.6.4 Command ser - serial link diagnostic counters
This command prints the I/O bus diagnostic counters for this module.

If any of above values that have err at the end are non-zero, it means that the AIM
has experienced transmission errors on the I/O bus. This can be an indication of a
problem with the AIM module or with a CPU module.
6.6.5 Command freq
– print status of Frequency Inputs
This command prints the measured frequencies and accumulated pulse counter
values of
all four frequency inputs. Example:
>freq
1:
1000.00Hz 347412
2:
400.00Hz 17684
3:
0.00Hz

4:

2:
399.00Hz 18667
3:
0.00Hz
0
4:
0.00Hz
0
Above example shows that the frequency input 1 sees a frequency of 1000 Hz and
1001 Hz in successive readings and the frequency input 2 sees 400 Hz and 399 Hz.
The pulse counter values can be seen incrementing after successive commands.
6.6.6 Command in [num] - print input channel values
When given the num parameter (num=1...10), this command prints the status of a
single input. Without num, prints status of all 10 channels.

In the example above (values in bold for emphasis), different voltages were supplied
to the inputs 1, 3, and 7. Input 1 sees 5.010 V, input 3 sees 3.960 V, input 7 sees
8.050 V. Current input 10 was supplied 16mA from a calibrator and reads as 16.050
mA. These printed voltage values should be close to ones measured with a
multimeter. Rest of the inputs were not connected and show some values near zero
volts and milliamperes.
