Additional System Components
Microprocessor Controller and Electronics
Six proprietary electronic board assemblies monitor and control Analyzer functions:
• System board including the 32-bit microprocessor, 1 MB of program memory, 1 MB of data memory,
battery-backed nonvolatile memory for operator settings, digital I/O, QVGA color graphics controller,
stepper motor controllers, printer output, RS-232 (serial) port, interface to USB storage devices, and the
Ethernet port.
• Analog-to-digital conversion board with integrated signal conditioning circuits for three conductivity
and four temperature measurements
• Color LCD QVGA display with touch panel
• Passive interconnect board
• ID board with nonvolatile memory for system specific coefficients
• I/O board with interfaces to external devices, via binary input, four alarms, and three 4-20 mA outputs
Data Outputs
The Analyzer has serial (RS-232), USB, and printer ports, allowing flexibility for exporting and printing data. Real-
time and historical data can be transferred from the Analyzer via the serial port to a computer using
communication software such as HyperTerminal (for details, see “Using HyperTerminal” on page 179). Historical
data can be transferred from the Analyzer via the USB port to a USB flash storage device (provided) and then
transferred to any computer that supports USB. The Sievers 500 RL On-Line TOC Analyzer also has three analog
outputs (4-20 mA) which can be customized to track specific data values, four alarms, and two binary ports.
Note:
The Analyzer cannot be directly connected to a computer via the USB port. Rather, the
Analyzer’s USB port can only be connected to a USB storage device, such as a USB flash
memory drive.
