Detailed Description

The CD295 DataView II is a two-line, 32-character LCD that can display real-time data from a PakBus data logger (see Compatibility information on the web page). Mounted in an enclosure lid, the CD295 allows you to view data without opening the enclosure. The display side of the CD295 is weatherproof. A stainless-steel cover is provided to help protect the display from the effects of ultraviolet radiation.

With the CD295, you can scroll through up to 30 public variables to view the latest measured value, its description, and units of measure. The poll rate is synchronized with the data logger's execution interval, allowing the values to be updated as they are measured. PC295 software is provided with the CD295.

Additional Compatibility Information

Data Logger Considerations

The CD295 is a PakBus device with a default PakBus address of 4090. In turn, it uses PakBus communications to retrieve data from the attached data logger. The CD295 does not support PakBus Encryption.

Version 2 or higher

The original release of the CD295 operating system (version 1) and PC295 software (version 1) supported only the CR200-series dataloggers. Version 2 of the CD295 operating system (OS) and PC295 added support for the 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, customers with version 1 need to upgrade both their CD295 OS and PC295 software.

Use in Enclosures

The display is mounted in the lid of our enclosures. Installing the CD295 in an enclosure lid allows the user to view real-time data on-site without opening the enclosure. The display side of the CD295 is weatherproof. A stainless-steel cover is provided to help protect the display from the effects of ultraviolet radiation.

The 18132 is a common accessory for our standard enclosures. When the 18132 is ordered, Campbell Scientific will install the CD295 in the enclosure lid before the enclosure leaves the factory. Alternatively, the user can do the installation; O-rings, screws, and a drilling template are included with CD295 for this purpose.
