(the transmitter is not transmitting until there are enough
GNSS satellites received).
• [13]: DC Power input and serial port A (RS232). A
Fischer, 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 (cf. base
setup using an external radio transmitter).
• [14]: Ethernet connector. A Fischer, seven-contact female
connector allowing you to connect the SP90m to a local
network (LAN). Through this connector, you may remotely
control and monitor the SP90m from any computer
connected to the Internet. Data may also flow through this
port, 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.
