Unpacking the CTD-N and Connecting It to
Your Computer
Before deploying a CTD-N, it must be connected to an available serial port of a computer running
CTDPro and configured for deployment. It is also required to connect the instrument to the com-
puter when downloading data. The default serial port that CTDPro uses is COM1, and the default
baud rate is 9600 bits/sec. However, any serial port from COM1 to COM16 can be used, and baud
rates of 1200 and 19200–115200 bits/sec are additionally available. This section provides instruc-
tions on how to unpack the CTD-N and connect it to your computer using an RS-232 or RS-485 in-
terface, how to install and start CTDPro on your computer, how to change the serial port that
CTDPro uses, and how to change the baud rate at which the computer and instrument communi-
cate.
Unpacking the CTD-N
Before unpacking the CTD-N, check the shipping container for signs of external damage. If the con-
tainer appears damaged, report the damage to TRDI and to the freight carrier.
When unpacking the CTD-N, inspect all the items for any apparent damage and verify that all the
items listed in the packing list are included in the shipment. Report any damage or missing items to
TRDI.
Battery Pack
An internal alkaline battery pack is used to power the CTD-N when the instrument is deployed au-
tonomously. However, if a battery pack was ordered with the CTD-N, it will not be installed to pre-
vent possible damage to the instrument from an unexpected battery discharge. The battery pack
comprises 16 welded alkaline "C" size cells.
NOTE.
Although a battery pack is required for an autonomous deployment, it is not required
when configuring the CTD-N.
