RS-232
The display can be connected to a printer, computer or data collector via the RS232
interface. When a reading is accepted into memory, a peak is cleared, or data is
transmitted via the print data menu(s), it is transmitted via the RS-232 port. To download
the readings, go to the DATA MENU. Auditor has special software available to download
the readings, or they can be viewed with a terminal emulator program such as
HyperTerminal (included in all versions of Windows before Vista under
Start>Programs>Accessories>Communications), or a free terminal program such as
PuTTY.
