DataView II (CD295) Dual Line Display

1. Introduction

The DataView II is a two line, 32 character LCD that displays real time values
from a CR2xx series datalogger along with a pre-defined description string and
units string.

Two buttons allow the user to scroll through the programmed locations that are
updated as often as they are measured. When the user has not pressed a button
within a user-defined period (default 120 seconds), the DataView II switches
to low power mode, drawing a current of less than 1mA.

The DataView II is easily configured using the Windows based PC295W and
DevConfig packages.

Throughout this document the terms ‘DataView II’, ‘CD295’
and ‘DataView2’ are used interchangeably.


1.1 Changes from Version 1 to Version 2

The original release of the CD295 operating system (V1.0) and PC295 (V1.0)
supported the CR200-series dataloggers only. Version 2 of the CD295
operating system and PC295 added support for our CR1000, CR800, CR850,
and CR3000 dataloggers, as well as support for their new data types (long
integers, Booleans, strings, and time stamps).

To use the new capabilities, both the CD295 operating system (OS) and PC295
software needs to be upgraded to Version 2. Refer to Section to
upgrade the CD295 OS. To upgrade PC295, uninstall previous software
versions and then follow the procedure provided in Section 3.2.
