1.1 Introduction to the XL™ Series Data Logger
The XL Series of data loggers started with the H-350XL and the H-500XL and expanded from
there to a total of five major products, that all use the same basic programming methods and
other common features and functionality. The XL Series of data loggers / DCP’s now includes
the following products.
H-500XL Basic XL Series data logger.
H-350XL Basic XL Series data logger with built in pressure transducer.
H-510XL Basic XL Series data logger with built in shaft encoder.
H-522Plus Basic XL Series data logger with built in GOES HDR transmitter.
H-522 Same as H-522Plus but does not include the built in keypad / display.
Customer driven enhancements have vastly expanded the capabilities of the XL Series products
since its introduction early in 2000. Below is a quick overview of the common features of all the
XL Series data loggers followed by a list of differences for each product.
Uses, Functions, Features, and Attributes of the XL™ Series Data Logger / DCP:
! Operates over a wide temperature range: - 40EF to +140EF (- 40EC to +60EC).
! Easy to use program interface and push button keypad. Programming does not require an
external device (i.e., a laptop computer), although all programming and data retrieval can
be done through the serial port on a PC. (keypad and display not available on the H-522
model).
! Provides a bright, easy-to-read display with automatic power shut-off after 5 minutes.
! Four general purpose analog input channels.
! Switch closure event counter.
! AC frequency counter allows direct input for wind speed sensors, etc.
! Designed to output a 4-20 mA signal (No external module required).
! Three serial ports provide for easy installation of multiple serial devices.
! Complete serial interface provides both a command mode for automated use and a menu
mode for human interaction. Both modes provide complete system programming and data
retrieval.
! Built-in data logging functions which store the data in non-volatile internal memory.
! Common interface support for 100, 300, and 1200 Baud GOES Transmitters.
! Support for basic to complex math operations for non-linear sensors.
! Designed to be compatible with all SDI-12 data loggers, and sensors.
! Packaged in a sealed NEMA 4 enclosure.
! Built in BASIC language interpreter for user defined XL-Basic programs.
