The CR10X provided sensor measurement, timekeeping, data reduction, data/program storage and control functions. The CR10X stored up to 62,000 data points. Data and programs were stored either in a nonvolatile Flash memory or RAM. A lithium battery backed up the RAM and real-time clock. The CR10X also suspended execution when primary power (BPALK, PS100) dropped below 9.6 V, reducing the possibility of inaccurate measurements.

Expand AllCollapse All

  1. The CR10X has battery-backup RAM and clock. In other words, the program, final storage data, or clock settings are not lost if ac power is lost. Data is sent to final storage by an internal program. Data can be sent by an internal program from final storage to a storage module, computer, or printer using Instruction 96 Active Serial Data Output.

  2. The CR10X uses downloadable operating systems instead of PROMs and includes more instruction in the standard operating system. For a list of instructions included in the standard operating system, refer to the prompt sheet or CR10X manual.

  3. If the CR10X has Modbus OS, Wonderware can be used to display the data. Without the Modbus OS, LoggerNet software would be needed to collect the data and then the PC-OPC Sever software would be used to display the data.

  4. Yes. The data can be obtained directly from the CR10X using the Modbus protocol. The data logger must have a Modbus operating system installed. The Modbus operating system can be purchased initially with the data logger, or contact Campbell Scientific for a Modbus OS to retrofit the CR10X. Refer to the 13619 CR10X Modbus Operating System on CD page.

    An alternate method of obtaining the data is using OPC. Our LoggerNet and PC-OPC software are needed. The version of Wonderware must also work with OPC.

  5. Instruction 15, Control Port Serial I/O, does allow the use of one control port for hardware flow control (RTS/DTR) or (TXD/RXD). The first control port is the (RTS/DTR) line. Baud rate is limited to 300 or 1200. 

  6. If the RF modem has a CS I/O connector, then it should be compatible with the CR10X without the use of an SC932A. Ensure that the RF modem’s firmware is compatible with the CR10X firmware.

    Note: RF modems that are not sold by Campbell Scientific will only interface with a CR10X via an SC932A or an SC105. 

  7. Not the same, but similar. The SDM-SIO4 provides RS-232 voltage levels; the CR1000 control ports provide 0 to 5 V only. Both usually work with all sensors, and both devices are compatible with RS-232 and TTL logic. The CR1000 is easier to set up and program for serial input. The SDM-SIO1 is a preferred alternative to the SDM-SIO4.

    When compared to the CR10X, the CR1000 can handle strings as a specific data type. It also has more integrated serial interfaces including the following:

    • Four control port pairs—COM1 (C1 TX / C2 RX) through COM4 (C7 TX / C8 RX)
    • RS-232 port
    • CS I/O port for connection to CS I/O peripherals

    The serial I/O capabilities of the CR1000/CR3000 are similar to, and faster than, the SDM-SIO4 capabilities on a CR10X or CR23X. SDM devices are addressable and are connected to a data logger on C1 through C3. Therefore, one benefit of using multiple SDM devices on a CR1000 datalogger is that only three control ports are used.
