9. Remote Operation
9.1 Remote Interface
The calibrator can be remotely controlled using a PC terminal, or by
a computer program running the calibrator in an automated system.
It uses an RS-232 serial port connection for remote operation.
NOTE: To use the remote control option a custom RS-232
cable must be purchased from OMEGA (LEM232). To contact
OMEGA refer to Section 1.1 of this manual. With this connection
the user can write programs on a PC, with Windows languages like
Visual Basic to operate the calibrator, or use a Windows terminal,
such as Hyper Terminal, to enter single commands. Typical RS-232
remote configurations are shown in Figure 13.

Note: The RS-232 connection cable should not exceed 15m unless
the load capacitance measured at connection points is less than
2500pF.
