Section 4. Quickstart Tutorial
4.2.1 What You Will Need
4.2.2 Hardware Setup
4.2.2.1 External Power Supply
The following items are needed to complete this exercise:
• Campbell Scientific CR1000 datalogger
• Campbell Scientific PS100 12 Vdc power supply (or compatible power
supply) with red and black wire leads.
• Thermocouple (included with the CR1000)
• Personal Computer (PC) with an available RS-232 serial port (a USB-to-RS-
232 cable may be used if an RS-232 port is not available).
• RS-232 cable (included with the CR1000).
• PC200W software. This software is available on the Campbell Scientific
ResourceDVD or at www.campbellsci.com.
Note If the PC is to be connected to the RS-232 port for an extended period, use
the Campbell Scientific SC32B interface to provide optical isolation. This protects
low level analog measurements from outside interference.
Note The thermocouple is attached to the CR1000 later.
With reference to the figure Power and RS-232 Connections,
1. Remove the green power connector from the CR1000.
2. Verify that the red wire on the PS100 is attached to a PS100 12V terminal, and
the black wire is attached to a PS100 G terminal.
3. Verify the on/off switch on the PS100 is in the Off position.
4. Attach the red wire from the PS100 to the terminal labeled 12V on the green
connector.
5. Attach the black wire from the PS100 to the terminal labeled G on the green
connector.
6. After confirming the correct polarity on the wire connections, insert the green
power connector into its receptacle on the CR1000.
7. Connect the RS-232 cable between the RS-232 port on the CR1000 and the
RS-232 port on the PC (or to the USB-to-RS-232 cable).
8. Move the on/off switch on the PS100 to the On position.
