CR1000

The CR1000 stores data in a binary format (1s and 0s) which is very compact. Campbell Scientific software, such as LoggerNet, collects the data in a this binary format and converts it to a readable format such as ASCII. The CR1000's Status Table contains information regarding how memory is allocated for data storage. One way to access this information is through LoggerNet's Connect Screen | Tools | View Station Status. The second tab lists the tables in the datalogger, along with the number of records in the table and the estimated time that the table will fill.

Yes. The NL115 allows the CR1000 to communicate over a local network or a dedicated Internet connection via TCP/IP.

The CRBasic help contains example program code for all instructions in the datalogger. Look for the Example link at the top of each instruction topic. Additionally, the CRBasic instruction list can be filtered by instruction type by choosing, for example, the SerialI/O subset of instructions.

The CR1000 can handle strings as a specific data type. It has built-in serial communications capabilities on the 1) four control port pairs COM1 (C1 Tx / C2 Rx) through COM4 (C7 Tx / C8 Rx), 2) RS-232 port, and 3) CSI/O port with the appropriate interface device. The serial I/O capabilities of the CR1000 are similar to and faster than the SDM-SIO4 capabilities on a CR10X or CR23X. SDM devices are addressable and are connected to a datalogger on C1 through C3. Therefore, one benefit of using multiple SDM devices on a CR1000 datalogger is that only three control ports will be used.

Yes. A CURS100 is used to convert a current signal (e.g. 4 to 20 mA) output by a sensor to a voltage that can be measured by the CR1000. The 100 ohm resistor used for the current shunt allows currents up to 50 mA to be read on a ±5000 mV range.

Short Cut for Windows is a free program generator for Campbell Scientific dataloggers including the CR1000. More information can be found at http://www.campbellsci.com/scwin

This issue occurs only with the D600 laptop and is solved by updating the D600's Ethernet driver from the Dell website.

Sending a serial string out one of the CR1000 COM ports will require at least two instructions. Generally, the SerialOpen instruction is used to set up the communication port, such as 115.2k, N, 8, 1. The instructions SerialOut or SerialOutBlock can be used to transmit a specified string. See the CRBasic help for examples of programs using each of these instructions.

The CR1000 can measure analog voltages in the ±5 Vdc range. A voltage divider such as the VDIV2.1 is required to reduce 10 Vdc to an acceptable range. See the VDIV10.1/VDIV2.1 manual for examples of wiring and programs. Alternatively, a basic CR1000 program can be generated using Short Cut for Windows. In Short Cut, from the Generic Measurements folder, choose either Differential Voltage or Single-Ended Voltage.

It depends on what you mean by wireless. Using telecommunications peripherals, the CR1000 can communicate with remote computers. Examples of “wireless” telecommunication options include: cellular telephone, licensed and spread spectrum radios and satellite communications. Additionally, our Ethernet interfaces allow the CR1000 to access, or be accessed by, the Internet or internal Local Area Networks.

These links allow the user to access remotely the datalogger's real-time data, stored data, and programming. Users can combine two telecommunication options. Popular telemetry options that can be combined include Ethernet-to-UHF/VHF radio, multidrop-to-spread spectrum radio, phone-to-multidrop, ethernet-to-multidrop, and phone-to-UHF/VHF radio.

Yes. The CR1000 is fully programmable to output alarms. The CR1000 can initiate telecommunications such as sending an email or text message, providing audible voice synthesized information, or by calling a pager. The CR1000 can also activate physical alarms such as sirens and strobes. In this type of installation, a relay device, such as the A6REL-12, is typically used to send a control signal to the alarm device.

If you see the error message "The security code was not recognized by the station" in LoggerNet, or “Unable to send the program. Invalid security code” with PC4000, you may need to update your datalogger support software.

Using a CR1000 running Operating System Version Std.04 or later, the problem may be that LoggerNet or PC400 is interpreting the response from the datalogger incorrectly. Confirm that your new datalogger program is in your CR1000; typically you can update the table definitions and go on. Newer versions of LoggerNet and PC400 software resolve this problem.
