11. Connect another Ethernet cable from the other RJ-45 port of the 300SS to the
Ethernet port of the SM.
12. Refer to Grounding SMs on Page 172.
13. Wrap an AWG 10 (or 6mm
2
) copper wire around the Ground post of the 300SS.
14. Tighten the Ground post locking nut in the 300SS onto the copper wire.
15. Securely connect the copper wire to the grounding system (Protective Earth)
according to applicable regulations.
16. Connect a ground wire to the 300SS.
17. Replace the cover of the 300SS surge suppressor.
18. For coarse alignment of the SM, use the Audible Alignment Tone feature as
follows:
a. Set the 2X Rate parameter in the SM to Disable.
b. At the SM, connect the RJ-11 6-pin connector of the Alignment Tool Headset
to the RJ-11 utility port of the SM.
Alternatively, instead of using the Alignment Tool Headset, use an earpiece
or small battery-powered speaker connected to Pin 5 (alignment tone output)
and Pin 6 (ground) of an RJ-11 connector.
c. Listen to the alignment tone for
◦ pitch, which indicates greater signal power (RSSI/dBm) by higher
pitch.
◦ volume, which indicates better signal quality (lower jitter) by higher
volume.

cable
d. Adjust the module slightly until you hear the highest pitch and highest
volume.
e. If the Configuration web page of the SM contains a 2X Rate parameter, set it
back to Enable.
19. When you have achieved the best signal (highest pitch, loudest volume), lock the
SM in place with the mounting hardware.
