CiTaDel / WorkHorse ADCP Interface
1.
Introduction
This application note describes how a Teledyne RD Instruments WorkHorse ADCP
with Firmware 16.20 and greater can be interfaced with a TRDI CiTaDeL CTD with
Firmware 5.12 and greater.
The TRDI CiTaDeL CTD is attached to the WorkHorse via an adapter cable (see
Interface
Cables) that connects the WorkHorse RS-485 communications to the RS-
232 communications of the TRDI CiTaDeL CTD.
The WorkHorse interrogates the TRDI CiTaDeL CTD and stores the TRDI CiTaDeL
CTD data in the WorkHorse.

license exception or other approval from the appropriate U.S. Government agency before being exported from the United
States or provided to any foreign person. Diversion contrary to U.S. law is prohibited.
To enable the TRDI CiTaDeL CTD interface you must add the
CC000000001 command to the command file.
Data is stored in the WorkHorse, not the TRDI CiTaDeL CTD.
The data stream stored in the WorkHorse from the TRDI CiTaDeL
CTD can be as long as necessary and easily exported using TRDI
WinADCP.
