Connecting the detector to a computer
For example, the user can communicate easily with the detector using the Ter-
minal or Hyper Terminal program in Windows®.
Selectable printer types
Most PC-printers with serial interface can be connected to the 9-pin printer
port. Parallel (Centronics) interface printer can be used if connected through a
serial to parallel converter. The port can be set up for the following printer
types: PC Printer and Data Dump.
No printer
Printer output disabled. Incoming communication is enabled. Sensistor ISH2000
listens for incoming data but will not print/send test results.
PC printer (with serial interface)
The PC Printer option can be used to print data on most standard PC printer
with serial interface. Parallel interface printers can be used if connected through
a serial to parallel converter.
Note: The output format has been chosen to be as simple as possible to ensure
that most printers will accept it. Therefore, the printer output does not use any
flow control. This means that some printers may delay printing until the input
buffer is full or a pre-defined timeout has elapsed.

Note: Due to the large variety of printers available on the market, INFICON
AB does not take responsibility for the operation of a particular type of printer.
Printed data
The detector can print the following information:
1 Date and Time for Power on of detector.
2 Time of print.
3 Value of all gas signals above the Reject Level.
4 Test result: “Accept” or “Reject”.
5 Value of signal obtained during active test.
6 Result of calibration: “OK” or “Calibration Not saved”, Date and Time,
Parameter settings.
Printing of the current value can also be requested by an RS232 command or
ordered manually by pressing PRINT.
