The TempScan/1100 and MultiScan/1200 are
high-speed, compact, rack-mountable instru-
ments that measure up to 992 or 744 channels
of temperature or voltage, respectively.
Because of their unique architecture, both
instruments offer unrivaled low cost per
channel. They connect to a computer via
IEEE 488, RS-232/422, or Hayes-compatible
modem and can be disconnected from the
PC for stand-alone operation.
TempScan/1100
The TempScan/1100 is well suited for
temperature and lower-voltage measure-
ment because its solid state scanning pro-
vides temperature readings at speeds up
to 960 channels/s, an important feature
in applications that require monitoring
of tens or hundreds of channels.
MultiScan/1200
The MultiScan/1200 is ideal for tempera-
ture and voltage measurements that re-
quire more channel-to-channel isolation
than the TempScan/1100 can offer. The
unit provides 500V of channel-to-chan-
nel isolation for voltage and 200V of chan-
nel-to-channel isolation for thermo-
couples. The MultiScan/1200 uses relays
to provide isolation and to scan thermo-
couples and volts at up to 147 channels/s.
The unit can also digitize waveforms on a
single channel at up to 20 kHz.

Expansion Ar chitecture
The TempScan/1100 and MultiScan/1200 can each accept one
scanning module, which provides all of the required signal condi-
tioning. If your application demands more channels than are
available on a single module, you can use either the 2-slot Exp/10A
or the 10-slot Exp/11A expansion chassis. Multiple Exp/10A and
Exp/11A chassis can be daisy chained to a TempScan/1100 or
MultiScan/1200, providing up to 30 additional slots. Regardless of
the number of expansion chassis connected, there is only one link
to the computer, via its IEEE 488 or serial interface. As a result, the
TempScan/1100 or MultiScan/1200 appears to the PC as one
unified multichannel instrument.
TempScan/1100 and
MultiScan/1200 Expansion
The TempScan/1100 and MultiScan/1200 instruments can each
control up to 15 Exp/10A two-slot expansion chassis. The
Exp/10A’s form factor is identical to that of either instrument.
When attached to the TempScan/1100, the Exp/10A is config-
urable for 32 or 64 input channels, providing a total expansion
capacity of up to 992 channels. When attached to the
MultiScan/1200, the Exp/10A is configurable for 24 or 48 input
channels, providing a total expansion capacity of up to
744 channels.
For TempScan/1100 systems consisting of more than 96
channels, the 10-slot Exp/11A expansion chassis provides an
economical and convenient solution. One Exp/11A provides
up to 320 input channels in a compact and convenient
enclosure. Multiple Exp/11A chassis can be connected to one
TempScan/1100 to provide a total system capacity of up to
992 channels.
For MultiScan/1200 systems of more than 72 channels, the
10-slot Exp/11A is recommended and accommodates up to 240
input channels. Multiple Exp/11A chassis can be connected to
one MultiScan/1200 providing a total system capacity of up to
744 channels.

Scan Technique. The TempScan/1100 uses a technique whereby
groups of 16 consecutive channels are scanned during every AC
line cycle (i.e., channels 1 to 16 are scanned during the first AC
line cycle, channels 17 to 32 are scanned during the subsequent
AC line cycle, and so forth). This results in maximum measure-
ment rates of 960 channels per second (60 Hz) or 800 channels
per second (50 Hz).
Per Channel Scan Rate1,2,3,4: The rate at which
individual channel values are updated depends on the
total number of channels scanned and the AC line
frequency (60/50 Hz).

Scan Interval. For applications that require the logging of data
at a specified time interval, the TempScan/1100 offers a pro-
grammable scan interval. The effect of the scan interval is
illustrated in the example below.
Line-Cycle Integration Mode. The MultiScan/1200’s ability to
sample and average 32 measurements per line cycle makes it
useful for high-accuracy applications and is recommended for
thermocouple measurements. What’s more, when engaged in
line-cycle averaging, the unit provides AC or DC voltage, or
linearized and compensated thermocouple-based temperature
readings at up to 44 channels/s. The MultiScan/1200’s AC
voltage measurement capability is ideal for power-line monitor-
ing applications. For each measurement, the unit calculates the
equivalent true RMS voltage based on 32 samples it acquires
during each AC line cycle.
High-Speed, Multichannel Scanning Mode. When the
MultiScan/1200’s line-cycle averaging is disabled, the unit can
average 1, 2, 4, 8, 16, or 32 samples per channel. When the unit
is configured to take one sample per channel, it can scan 147
channels/s—or all of its potential 744 expansion channels in
approximately 5 seconds. This is important if the application
involves monitoring tens to hundreds 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
MultiScan/1200 can sample at up to 20 kHz on a single channel and
store the data in its memory, which can be expanded up to
8 Mbytes. When performing post-acquisition waveform analysis
such as Fast Fourier Transforms (FFTs), the unit can return each data
point in a waveform to your program. Alternatively, the unit can
provide a true RMS value of the equivalent AC voltage.
1. All thermocouple measurements are cold-junction compensated and linearized
2. Per-channel scan rate may be lower if channels are skipped
3. The per-channel scan rate may be calculated using the formula at right:
4. Divide the per-channel scan rate by 4 if using thermocouple wire > 500 ft.

& MultiScan/1200

General Information
Scanning Capabilities
The TempScan/1100 and the MultiScan/1200 provide an array of
scanning capabilities to meet your application requirements. Be-
cause data-logging applications frequently require the logging of
readings at fixed time intervals, the TempScan/1100 and the
MultiScan/1200 use the standard hours-minutes-seconds
(hh:mm:ss.s) format to specify the time interval between channel
scans. Users can configure the units to begin and end data logging
on a specified event—such as a TTL signal, temperature level, IEEE
GET, alarm condition, or absolute time of day—or upon completion
of a specified number of readings.
Two Programmable Scan Rates. The TempScan/1100 and the
MultiScan/1200 offer two programmable scan rates for applica-
tions that require acceleration of the measurement rate on a
specified event, such as an alarm condition. For example, you can
program the instruments to sample once per minute and then,
upon the occurrence of a specified alarm condition, switch to
sampling once per second. Upon cessation of the alarm condition,
the units resume sampling at the rate of once per minute.
Accuracy
The TempScan/1100 and the MultiScan/1200 have a number of
features and capabilities that enable them to deliver the high
accuracy demanded by many research applications.
High Resolution. Each unit is equipped with a high-speed
16-bit A/D converter. This enables the TempScan/1100 to offer
up to 0.1˚C and 3.05 µV resolution with the TempTC/32B
scanning module and allows the MultiScan/1200 to offer the
same with the MTC/24 scanning module.
Noise Filtering. The TempScan/1100 filters AC line cycle
noise by sampling and averaging 16 measurements per line
cycle. The MultiScan/1200 does so by sampling and averag-
ing 32 measurements per line cycle. The MultiScan/1200 also
offers the additional flexibility to average across multiples of
1, 2, 4, or 8 line cycles.
High-Accuracy Cold Junction Compensation. The TempTC/32B
and the MultiScan/1200’s MTC/24 thermocouple/volt scan-
ning modules both feature multiple, strategically located tem-
perature sensors that provide high-accuracy, cold-junction com-
pensation across all of its inputs.
Accurate Linearization. The TempScan/1100 and the MultiScan/1200
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. The units can also store up to two user-defined
lookup tables in nonvolatile RAM (NVRAM) for use with user-
defined thermocouple linearization curves.
Alarms
Many process-control applications require periodic monitoring
until the occurrence of an alarm condition; then they require the
acceleration of measurement and the provision of closed-loop
control signals until the process returns to a steady state.
The TempScan/1100 and the MultiScan/1200 offer a number of
capabilities and features that facilitate such applications. For
example, they provide 32 digital alarm outputs that can be acti-
vated on a per-channel basis via user-specified alarm conditions,
and they automatically return their alarm outputs to steady state
once limit conditions are resolved.
The units’ ability to automatically update alarm outputs in real-
time affords you greater control of your applications and re-
duces your programming burden by eliminating the 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).
Real-T ime Clock
The TempScan/1100 and the MultiScan/1200 each feature a
real-time clock that allows you to synchronize acquisition to a
specific time of day. During acquisition, the TempScan/1100
and the MultiScan/1200 store the time and date of every data
scan in memory, enabling later retrieval of this information for
use in plotting and analyzing measurements over time. The
instruments also time and date stamp each channel’s high and
low excursions, providing a precise time record of a channel’s
minimum and maximum values.
Memory
For high-speed and long-term data logging, the
TempScan/1100 and the MultiScan/1200 are equipped with
128 Kreadings of data storage, which can be field upgraded by
the user to 4 Mreadings. Because individual measurements
are not necessary for all data logging applications, the units
make each channel’s high, low, and last readings available
throughout acquisition.

IEEE 488. The TempScan/1100 and the MultiScan/1200’s IEEE
488 interface can transfer data at up to 300 Kbytes/s. The
interface lets you log readings directly to a controlling computer’s
hard disk in real time, making it compatible with IOtech’s
complete line of IEEE 488.2 controllers for PCs (see p. 263).
RS-232/422. The TempScan/1100 and the MultiScan/1200’s
RS-232/422 interface can connect directly to a notebook or
desktop PC’s serial port. This makes the units suitable for
process control and environmental control, as well as for
other applications that require instruments to be located
remotely from the controlling computer.
The RS-232/422 interface provides switch-selectable baud rates
from 300 to 9600. The units’ RS-232/422 port also enables their
use with IOtech’s complete line of Serial Communication Boards
(see p. 297). These boards let users control multiple test stations
from one PC, enabling them to perform data acquisition at
multiple, distant locations.
