Receiver Description
UHF Input
A TNC coaxial female connector [6] allowing you to connect
a radio whip antenna. This connector is available only if the
ProFlex 800 has been fitted with a radio module. (Connector
[6] is missing from the rear view above.)
Warning! Do not confuse this coaxial input with the GNSS
input [2] below. Connecting a GNSS antenna to the UHF
input might damage it if the embedded UHF transmitter is
used (although the transmitter is not supposed to transmit
until there are enough GNSS satellites received).
Ethernet Port
A Fischer, seven-contact female connector [7] allowing you to
connect the ProFlex 800 to a local network (LAN). Through
this connector, you may remotely control and monitor the
ProFlex 800 from any computer connected to the Internet.
Data may also flow through this port, in the same way as
through a serial port.
GNSS Input #2
A TNC coaxial female connector [8] for applying an external
reference clock. (Connector [8] is missing on the rear view
above.)
CAN 2.0 Bus
A Fischer, five-contact, female connector [9] allowing you to
connect the ProFlex 800 to external, NMEA2000-compatible
equipment via CAN bus. (For future use.)
Earth Terminal
A screw terminal [10] for connecting the receiver chassis to
Earth.
Electric Isolation
All signals available on the following connectors are optically
isolated from the receiver’s internal circuitry and chassis
ground, as well as from each other:
