Current Version: 3.4

PConnect software supports communications between a Palm OS-based PDA and a Campbell Scientific datalogger. It allows you to carry only your PDA and cables instead of a laptop computer to interface with your datalogger and collect your data.

Detailed Description

The software is supplied on CD-ROM. The connection between the PDA and datalogger is supported by a variety of mechanisms (direct serial connection, RF401-series spread spectrum radio, SC-IRDA Infrared interface, and Bluetooth). Please see the information under the Compatibility tab for details.

PConnect can be used to collect data from the datalogger, and transfer the data to an office PC. Collected data is transferred to the PC during the HotSync process. This process also synchronizes program files between the PDA and PC.

Functions supported by PConnect include the capability to:

  • Communicate at baud rates of 38,400 bps (CR1000, CR800, CR850, CR23X, CR3000) and 9,600 bps (all other dataloggers)
  • Create unique station files for each datalogger
  • Collect data from the datalogger
  • Transfer datalogger programs between the datalogger and PDA
  • Display real-time and historical data. Real-time data is updated every two seconds
  • Graph one element from any array
  • Set datalogger flags, ports, and clock
  • Access the datalogger terminal mode
  • Use memory expansion cards to augment the PDA's memory



Current Version Version 3.4 began shipping in December 2009.

Datalogger Considerations

Compatible Contemporary Dataloggers

CR200(X) Series1 CR800/CR8502 CR10003 CR30004 CR9000X

1The CR200(X)-series dataloggers require PConnect version 3.0 or higher.
2The CR800 and CR850 require PConnect version 3.3 or higher.
3The CR1000 requires PConnect version 3.1 or higher.
4The CR3000 requires PConnect version 3.2 or higher.

Compatible Retired Dataloggers

CR500 CR5105 CR10 CR10X5 21X CR23X5 CR9000 CR5000 CR7X

5For the CR510, CR10X, and CR23X, support for both the mixed-array and PakBus® datalogger operating systems is provided in PConnect version 3.0 or higher; prior versions only supported the mixed-array OS.

Datalogger Interfacing

  • PDA-to-CS I/O connector or PDA-to-RS232 cable.


  • SC-IRDA Infrared Interface connects to the CS I/O port (not compatible w/CR200(X)-series)

PDA Requirements

  • Operating system: Palm OS Version 3.3 or later (Pocket PC OS-based PDAs require PConnectCE)
  • Must be capable of serial communication
  • Memory: 2 MByte if collecting data from one standard datalogger; 8 MByte recommended when collecting from many stations or from dataloggers with extended memories
  • If using the SC-IRDA, the PDA must have an IRDA port and an IR chip set compatible with the SC-IRDA.
  • For Bluetooth communication, the handheld must be Bluetooth enabled.

Communication Requirements

PDA Connection for Serial Communication

PDA-to-serial cable or cradle (one end of the cable/cradle must terminate in a 9-pin serial connector) is required. The cable/cradle connects to the PDA-to-CS I/O connector or PDA-to-RS232 cable via the 9-pin serial connector. This cable/cradle may be included with the PDA, or it may need to be purchased as a separate accessory from the PDA manufacturer or a third party supplier.

Bluetooth Communication

Third-party Bluetooth serial adapter is required. The interface and/or cables that are used to connect the adapter to the datalogger will vary, depending upon whether the device acts like a DTE (computer) device or DCE (PDA) device. In some instances, this is evident by the pin-out of the adapter, but not always. A general rule is if the adapter has a 9-pin female connector, then the adapter is connected to the datalogger using the PDA-to-CS I/O connector for the CS I/O port or the PDA-to-RS232 cable for the RS-232 port. If the adapter has a 9-pin male connector, then the adapter is connected to the datalogger using an SC32B for the CS I/O port or it can be connected directly to the RS-232 port.
