2.7.2 ESTABLISHING COMMUNICATIONS USING HyperTerminal
This section shows how to communicate with 1020 using the Windows based communication pro-
gram HyperTerminal. It assumes that you’re familiar with Windows 95/98/NT/2000/XP and have a
basic understanding of serial communications.
All IBM compatible computers provide at least one serial port using a 9-pin connector. The port desig-
nation can be either COM 1 or COM 2. Usually, when a computer has two serial ports, COM 1 will be
the 9-pin connector and COM 2 will be the 25-pin connector. However, port designations can vary from
manufacturer to manufacturer, so you will have to positively identify the COM port you wish to use for
the flow computer interface. Connect cable between the flow computer and your PC using the 9-pin
connector.
NOTE: Be aware that on some laptop computers, the available COM ports may be assigned to
peripheral devices, such as a modem, mouse or an infrared port, etc. Therefore, you
may not have a COM port available for this interface. In such a case, refer to your PC
manual for instructions on how to reassign your COM ports for standard operation.
