APPENDIX 143
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 attaching 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 communi-
cations instead. If your computer only supports USB communications, you may want to use
a Click serial to USB converter to make a direct connection.
Appendix D – Target Roll Angles for Alignment
The following appendix provides quantitative information about how far the sensor should
be rolled during installation.
The following table is similar to Table 1.1, except that it lists a target roll angle in addition
to a target distance (see Table D.1). For example, if the sensor were mounted 30 ft. (9.1 m)
high with a 50‐ft. (15.2-m) offset, the target distance would be 110 ft. (22.9 m) and the target
roll angle would be 66°.
It is helpful to know that in some cases during installation the sensor could be rolled so that
it appears to be the laying virtually on its side. Using Table D.1 will help you achieve the full
detection potential of the sensor.
