Warning!
Do not confuse this coaxial connector with the
GNSS inputs. Connecting a GNSS antenna to the UHF
connector might damage it if the embedded UHF
transmitter is used (however the transmitter will not be
transmitting until there are enough GNSS satellites
tracked and used).

[13]
: DC Power input and serial port A (RS232). A seven-
contact, female connector allowing the SP90m to be
powered from either the provided AC adapter (connect the
cable extension between SP90m and the end of the AC
adapter output cable), or an external 9- to 36-V DC power
source through cable P/N 730477 (e.g. base setup using
an external radio transmitter).
•
[14]
: Ethernet connector. A 7-contact female connector
(RJ45) allowing you to connect the SP90m to a local
network (LAN). Through this connection, you may remotely
control and monitor SP90m operation from any computer
connected to the Internet. Data may also flow through this
connection, in the same way as through a serial port.
•
[15]
: RS232 serial port F, a SubD, nine-contact, male
connector. The PPS signal and the not operational yet
CAN bus are also available on this connector.
•
[16]
: Earth terminal. A screw terminal 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:
•
Serial ports A, B and F (including DC power output
voltage on port A)
•
Ethernet port
•
USB port
•
[17]
: Switchable RS232/RS422 serial data port B
(default is RS232), a SubD, nine-contact, male
connector. The External Event input is also present on this
connector.
