Note
Note that the OSA Remote turns on at 10 V and will shut off below 9 V.
Ethernet Port
Connections
Communication over the OSA Remote Ethernet ports is via a small form-factor
pluggable (SFP) module. A Copper Ethernet SFP Interface Module is provided
and can be used with a Cat6 shielded copper cable to provide 10/100/1000
Mbps communication. An optional Fiber Ethernet SFP Interface Module can be
used with a fiber-optic cable to provide 1 Gbps Ethernet over fiber.
Ethernet connections are made by connecting the copper or fiber-optic cable
from one of the RJ45 connectors (labeled A and B in Figure 3-4) to a
networked device such as a Bedrock Control System workstation.
The following are the Cat6 shielded copper cable specifications:
•
10/100/1000 Mbps
•
full and half duplex communication
•
100 m maximum cable length
The following are the fiber-optic cable specifications:
•
9/125 μm single mode fiber (SMF)
•
1310 nm wavelength
•
1.25 Gbit bi-directional
•
Up to 10 km range
