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
HySpeed 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 (see below).
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.
Table 8-5. Communication specifications.
Note:
Due to the large variety of printers available on the market, INFICON does not
take responsibility for the operation of a particular type of printer.
