The PMP 400 SM and PTP 200 BH have a ground/Protective Earth lug, just like the AP. Although not as
critical as in the case of the AP (where there is metal-to-metal connectivity through the coax and antenna to
ground), the lug can be used to ground the SM or BH for additional protection. In addition, a 600SSH can be
used within 3 ft (1 m) of the SM or BH to provide additional protection. Especially for a BH, or in cases where
the SM is mounted high and is more exposed, or in known difficult areas for lightning, consider using these
two techniques to increase the radio's resistance to lightning.
In all cases where Ethernet cables penetrate a building, home, or telecommunications hut, mount a properly-
grounded 600SSH outside at the point of Ethernet cable building entry to protect persons and property in the
building.
PMP 400/430 and PTP 200/230 Series modules do not display a jitter value. Use Receive Power Level for
aiming and then use Link Tests to confirm alignment.
The Receive Power Level is a relative, not absolute, value. The Receive Power Level on a module is
useful during installation to aid in aiming where relative values over a short period of time are of interest. The
displayed Receive Power Level is not designed to be highly accurate over time. The displayed Receive
Power Level will vary with board-level temperature and may vary from module to module even if the actual
received power is not varying. Know the limitations and use caution and judgment for any other use of
Receive Power Level. Caution is advised when using Receive Power Level for monitoring a link over time,
deciding if the link is within operating margins, deciding if a link is serviceable (link tests give a much better
indication), or comparing the link to other links.
The alignment headset will play a tone that varies in pitch (received power level), but not volume (jitter),
since PMP 400/430 and PTP 200 Series modules don't calculate a jitter.
Usage of the alignment tone/headset is not supported with the PTP 230 product.
