TempScan / MultiScan User’s Manual 899493 System Overview 1-5
Data Storage & Format
Storage: 128 K reading (256 Kbyte) standard; optional 500 K reading (1 Mbyte), 2 M reading (4 Mbyte),
4 M reading (8 Mbyte).
Data Formats: ASCII and binary; binary format returns a 16-bit compensated and linearized temperature
value (0.1°C/bit); user-programmable for hi/low byte or low/hi byte. Note that high speed DMA
transfers are binary format only.
Statistical Parameters: High, Low, and Last available per channel. For MultiScan/1200: Not available
when in single-channel burst mode.
Time Stamping: Available for each scan group and for each channel’s high, low, and last parameters.
For MultiScan/1200: Not available when in single-channel burst mode.
Time Format: Absolute Time/Date stamping ( hh:mm:ss.mil,MM/DD/YY ), relative Time/Date stamping
( +hh:mm:ss.mil,DDDDDDD ) and scan interval timebase ( hh:mm:ss.t ). For MultiScan/1200: Not
available when in single-channel burst mode.
Alarm Stamp: Available for each scan group. For MultiScan/1200: Not available when in single-channel
burst mode.
Digital Input Stamp: Available for each scan group. For MultiScan/1200: Not available when in single-
channel burst mode.
IEEE 488 Interface
CAUTION
The IEEE 488 terminal must only be used to control a non-isolated IEEE 488
system. The common mode voltage (cable shell to earth) must be zero.
Interface Use: Digital communication (as opposed to analog) for IEEE 488 compliant computer platforms,
as well as IEEE 488 compliant platform-independent configurations. Messages sent 1 byte (8 bits) at
a time. Supports data rates up to 1 Mbyte/sec. Up to 15 devices can be connected to one bus.
Total bus length up to 20 meters. Allowable cable distance between devices is up to 2 meters.
Message transactions are hardware handshaked.
Installation Category: For CE: Category 1.
Implementation: SH1, AH1, T6, TE4, L4, LE4, SR1, PP0, RL0, DC1, DT1, C0, E1.
Programmable Parameters: Alarm set points, thermocouple type, temperature units, Trigger level,
Pre-Trigger and Post-Trigger scan interval, Trigger mode, SRQ mask, scan count, Pre-Trigger count,
digital input, digital output, real time settings, data output format, and terminators.
Data Transfer Speed: Up to >300 Kbytes/s.
Connector: Standard IEEE 488 connector with metric studs.
RS-232 Serial Interface
CAUTION
The RS-232 terminal is only for connecting devices having signals at serial
communications levels.
Installation Category: For CE: Category 1.
Baud Rates: 300, 600, 1200, 2400, 4800 and 9600.
Data Bits: 8.
Stop Bits: 1.
Parity: Even, Odd, None.
Handshaking: RTS/CTS, XON/XOFF (for ASCII transmissions only).
Connector: Male DB-9.
