NOTE. The Rio Grande End-Cap is Red to differentiate it from the Monitor
and Sentinel End-Cap. The I/O cable pin-out arrangement is different
between a Rio Grande and a Monitor/Sentinel.
CAUTION. Do not attach a Workhorse Monitor or Sentinel I/O cable or
power supply to the Workhorse Rio Grande ADCP. The Workhorse
Monitor and Sentinel ADCPs are 24 VDC systems. The Workhorse Rio
Grande uses 12 VDC only.
NOTE. Refer to the appropriate ADCP User's Guide for instructions on
how to connect and use the ADCP.
