O Series Data Radio – User Manual

Part D – System Planning and Design

Power Supply and Environmental

Considerations

Power Supply

The power supply should provide a clean, ﬁltered DC source. The

radio modem is designed and calibrated to operate from a 3.3VDC

and 5VDC regulated supply.
The power supply must be able to supply sufﬁcient current to

provide clean ﬁltered DC under the full current conditions of the

radio modem (i.e. when transmitting full RF power).

Site Earthing

The radio must not be allowed to provide a ground path from

chassis to (DB9) signal ground or (-) battery ground. Ensure that

the chassis mounting plate, power supply (-) earth, RTU terminal

device, and lightning arrester, are all securely earthed to a common

ground point to which an earth stake is attached.
