Note
If you do not have the right type of RS-232 physical connection you will
not be able to connect using the SmartSensor Manager software. Since null
modem cables and straight-through cables look similar, you may want
to label them. Alternatively, you may want to use a null modem adapter
instead of a null modem cable. If you do, you can turn your straight-
through cable into a null modem cable by aaching the adapter on one end.
If you wish to connect the SmartSensor cable’s RS-485 wires directly to a
PC or modem, this will require that these devices natively support RS-485
communications. Often, modern personal computers do not support RS-485
communications and support USB communications instead. If your computer
only supports USB communications, you may want to use a Click! serial to USB
converter to make a direct connection.
