Only pin 2 (Received data), pin 3 (Transmitted data) and pin 5 (Signal ground) are 
used. Refer to Figure 8-5 for the wiring diagram.

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 (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.
