Installation Planning - GE MDS SD Series Reference Manual

12 SD Series Ref. Manual (Packet & Transparent Mode)
At the Remote sites, serial and Ethernet-based RTUs are employed, and
responding to a specific host computer. In the case of the Remote shown
on the lower right side of the drawing, two RTUs are co-located, but
responding to different host computers and handling entirely different
streams of data. Multihost systems eliminate the need for two trans-
ceivers to support separate data collection/control networks.

4.0 INSTALLATION PLANNING

Careful planning of the installation site will help achieve optimal performance
from the transceiver. This section discusses the factors that should be consid-
ered prior to installing the radio. Step-by-step installation procedures begin on
Page 21.
Figure 10 shows a typical remote station arrangement. The specific details at
an installation site may vary, but there are three main requirements for
installing the transceiver in all cases:
• Adequate and stable primary power
• An efficient and properly installed antenna system
• Correct interface connections between the transceiver and the data
device.
