Communicating With Rs-232; Windows Hyperterminal Set-Up Instructions - Agilent Technologies G8610A Operation Manual

A.2 Communicating with RS-232
The RS-232 Protocol is intended for diagnostic purposes and initial set-up inquires. The
RS-232 connection is located on the rear D-sub 9-pin connector.
The leak detector RS-232 port is not an interrupt-driven port. It is configured as DTE
(Data Terminal Equipment), therefore the leak detector's RS-232 Protocol cannot be sent as
strings.
Windows 95 and later versions contain a serial communications program called
HyperTerminal, a useful tool in establishing communication between the leak detector and
a PC.
