POWER AND GROUNDING NOTES:
1. The EtherMeter requires a 9-36 VDC Power Supply (2.50 W Max). It is recommended
that the common of the DC power supply be bonded to earth ground.
2. All connected communication equipment must utilize the same ground reference. To
achieve this, a low-impedance ground bus wire should be tied to the DC common of each
connected communication device.
