GNSS Input #1
A TNC coaxial female connector [2] allowing you to connect
a GNSS antenna to the receiver via a coaxial cable.
Serial Data Ports
These are all Fischer, seven-contact, female connectors, each
allowing a serial connection to an external device.
• Ports F [3] and B [4] are both RS232-only ports
• RS232/422 Port A [5] is a switchable RS232/RS422 port
(Default is RS232).
As an option (installed at the factory), port A also delivers
a regulated DC power voltage between pin 1 (+12 V DC)
and pin 2 (GND) that can be used to power a connected
device. The DC current available is 0.5 A steady state, and
1.0 A peak.
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.
