5.4. RS-485 CONFIGURATION OF COM2
As delivered from the factory, COM2 is configured for RS-232 communications. This
port can be reconfigured for operation as a non-isolated, half-duplex RS-485 port. To
configure the instrument for RS-485 communication, please contact the factory. (Using
COM2 for RS-485 communications disables the optional USB com port).
5.5. REMOTE ACCESS VIA THE USB PORT (OPTION)
The calibrator can be connected to a personal computer by direct connection through
their respective USB ports.
1. Install the Teledyne T-Series USB driver on your computer, downloadable from the
Teledyne API website under Help Center>Software Downloads (www.teledyne-
api.com/software).
2. Run the installer file: “TAPIVCPInstaller.exe”
3. Connect the USB cable between the USB ports on your personal computer and
your calibrator. The USB cable should be a Type A – Type B cable, commonly
used as a USB printer cable.
4. Determine the Windows XP Com Port number that was automatically assigned to
the USB connection. (Start → Control Panel → System → Hardware → Device
Manager). This is the com port that should be set in the communications software,
such as APIcom or Hyperterminal.
