Select the appropriate data type for each channel using the table below. Refer to Table
3-6 for data type ranges.

If selected, the CJC format will override all ranges/formats and report the indicated CJC value
for this channel. Channel zero will report CJC0 directly. Channel 7 will report CJC1 directly.
All others will be distributed values between CJC0 and CJC1 based on channel position.
