personal computer (PC), where data can be sent from the Data Bucket to the PC over an
RS-232 link (up to a 38,400 baud rate), or the card can be removed and taken to a PC
equipped with a memory card reader (see Options and Accessories). Memory card
operations are discussed in Chapter 3.

Computer Operation
The Data Bucket can serve as a front-end data acquisition unit for PC-based operations,
operating over an RS-232 link. The applications software for operating the RS-232 link
includes the supplied Hydra Starter Package (Starter) and optional Hydra Logger
(Logger) (see "Applications Software" below). Computer operations are discussed in
Chapter 4.
Printer Operation
Measurement data from the Data Bucket can be routed to a printer via an RS-232 link.
At the completion of each scan cycle, measurement data is printed, providing hardcopy
output. Any compatible printer with a serial input may be used. Printers with a parallel
input may be used if they are equipped with a serial-to-parallel adapter. Printer
operations are discussed in Chapter 5.
Modem Operation
An RS-232 link between the Data Bucket and a modem allows data transfers over
telephone lines. Operation is similar to computer operations, except there is a modem
link instead of a direct RS-232 connection. The modem may be electronic or
programmable/electronic (Hayes-compatible). Modem operations are discussed in
Chapter 6.
