Multi-Drop CTD2 Command Data Format
The data format for the CTD2 command is essentially the CSV format with several
<CR><LF> characters inserted. All analog data channels are printed regardless of
how many are enabled. Unused analog channels will print “Nan”. See Appendix E,
"Comma Separated Value (CSV) Format".
