Isolated Inputs
The ChartScan/1400 and NetScan/1500 are ideal for temperature and voltage measurements that require channel-to-channel isolation. The systems provide 500V isolation for high-voltage applications using the CSN14/HV/S module and 200V isolation when the thermocouple and other voltage modules are used. The systems achieve this high isolation by using individual relays on each channel, yet still maintain a very fast 147 channels/s scan rate.

Expansion Options
The ChartScan/1400 and NetScan/1500 chassis can accommodate up to four plug-in option modules for a total of 64 channels. For larger systems, the CSN/Exp expansion chassis connects directly to the main unit to allow four additional plug-in modules, expanding the system from 64 to 128 channel capacity. Power is derived directly from the main unit so no additional power supplies or cables are required.

Faster Scanning
The ChartScan/1400 and NetScan/1500 offer faster scanning than a typical stripchart recorder, and exceed the typical two Hz rate found on most strip-chart, multi-point, or hybrid recorders. The units provide an array of scanning capabilities to meet your application requirements. Because data-logging and chart r e c o r d i n g applications frequently require logging at fixed time intervals, the systems use the standard hours-minutesseconds (hh:mm:ss.s) format to specify the time interval between channel scans. Users can configure the unit to begin and end data logging on a specified event such as a TTL signal, temperature level, IEEE GET, alarm condition, absolute time of day, or upon completion of a specified number of readings.

P r o g r a m m a b l e Scan Rates. The ChartScan/1400 and NetScan/1500 offer programmable scan rates for applications requiring acceleration of the measurement rate on a specified event, such as an alarm condition. For example, you
can program the instrument to scan once per minute and then, upon the occurrence of a specified alarm condition, switch to scanning once per second. Upon cessation of the alarm condition, the unit resumes scanning at the rate of once per minute.

Scanning Techniques
The ChartScan/1400 and NetScan/1500 offer three measuring modes for application flexibility. These include a line-cycle integration mode, a high-speed multichannel scanning mode, and a single-channel burst mode. A discussion of the particular attributes of each measuring mode follows. Line-Cycle Integration. The ability to sample and average 32 measurements per line cycle over multiple line cycles, makes the systems useful for high-accuracy applications and thermocouple measurements in applications subject to high AC noise environments. When engaged in line-cycle averaging, the units provide AC or DC voltage, or linearized and compensated thermocouple-based temperature readings at up to 44 channels/s. The AC voltage measurement capability is ideal for power-line monitoring applications. For each measurement, the unit calculates the equivalent true RMS voltage based on 32 samples it acquires during each AC line cycle.

Accuracy
The ChartScan/1400 and NetScan/1500 have a number of features and capabilities that enable them to deliver the high accuracy demanded by many research applications. High Resolution. The systems are equipped with a high-speed 16-bit A/D converter. This enables the systems to offer up to 0 . 1 ° C and 3.05 µ V resolution with the CSN14/TC/P thermocouple/volt scanning module. Noise Filtering. The systems reduce noise by sampling and averaging 32 measurements per line cycle. The systems also offer the flexibility to average across multiples of 1, 2, 4, or 8 line cycles. High-Accuracy Cold Junction Compensation. The systems' CSN14/TC/P thermocouple/volt scanning module features multiple, strategically-located temperature sensors that provide high-accuracy, cold-junction compensation across all inputs. Accurate Linearization. The systems enable quick and accurate linearization by providing built-in lookup tables for popular thermocouple types, including J, K, T, E, R, S, B, and N.
Temperature & Voltage Scanning Instruments
High-Speed Multichannel Scanning. When line-cycle averaging is disabled, the systems can average 1, 2, 4, 8, or 16 samples per channel. When the units are configured to take 1 sample per channel, they can scan 147 channels/s or all 128 channels in under one second. This is important when trying to timecorrelate a large number of channels. By contrast, data loggers and other temperature measuring instruments typically acquire readings at only 5 to 20 channels/s. Single-Channel Burst Mode. In single-channel burst mode, the systems can sample at up to 20 kHz on a single channel and store the data in memory, which can be expanded up to 4 Mreadings. When performing post-acquisition waveform analysis such as Fast Fourier Transforms (FFTs), the units can return each data point in a waveform to your program. Alternatively, the units can provide a true RMS value of the sampled voltage.

Alarms
Detecting an alarm condition is a common requirement in logging applications and the ChartScan/1400 and NetScan/1500 offer a number of modes to facilitate alarm detection. With 32 digital TTL alarm outputs available on the 50-pin rear panel connector or 16 outputs via the high-current capacity CSN/Relay option*, multiple conditions can be set and monitored. Unlike some instruments which allow only one channel to be assigned to a single alarm output, the ChartScan/1400 or NetScan/1500 allow one or more channels to be logically "OR-ed" and connected to an alarm output. In this way, all 128 channels can participate in the alarm process. Channel settings for alarm limit and hysteresis are individually set with the alarm output remaining high for as long as the alarm condition is valid.
Edge connector
CSN/Relay card supports 16 high-current alarm outputs The units' ability to automatically update alarm outputs in real time affords you greater control of your applications and reduces your programming burden by eliminating t h e need for constant per-channel monitoring by the controlling computer. In addition, the units can update alarmed output channels in real time, at their programmed scan rates, and can alert the host computer of active alarm conditions via an IEEE 488 service request (SRQ).
Memory
F o r high-speed and long-term data logging, the systems are equipped with 128 Kreadings of data storage, which can be field expanded to 4 Mreadings. Since each application requires different measurements, the units make each channel's high, low, and last readings available throughout acquisition.
NetScan Communication
Connecting a Local Area Network (LAN) or Wide Area Network (WAN) to the NetScan/1500 is simple via the standard 10BASE-T Ethernet interface. This allows any PC on the network to access the NetScan. In addition, a second port is available for RS-232/422 communication with a local PC. A serial-based device may be attached to this port and accessed through the NetScan/1500**. Internet. If the LAN or WAN has a gateway to the Internet, then a network PC can c o m m u n i c a t e with remotely located NetScans via TCP/IP protocol.
Real-Time Clock
The ChartScan/1400 and NetScan/1500 feature a real-time clock that allows you to synchronize acquisition to a specific time of day. During acquisition, the system stores the time and date of every data scan in
ChartScan Communication
C o n n e c t i n g your computer to the ChartScan/1400 is simple via the standard RS-232/422 interface. In addition, an optional IEEE 488 interface can be added via a simple plug-in module. ChartScan supports any Hayes-compatible modem.

memory, enabling later retrieval of this information for use in plotting and analyzing measurements. The instrument also time and date stamps each channel's high and low excursions, providing a precise time record of a channel's minimum and maximum values.
IEEE 488. The CSN/COM/488 option fully supports the IEEE 488.2 standard and can transfer data up to 300 Kbytes/s. This interface plugs directly into the communications port on the back of the unit and lets you set up, control, and log data from the instrument directly to the computer. IEEE 488 is most commonly used in multii n s t r u m e n t applications where one computer is used with many instruments.
