EFA-10 Fiber Optic Adapter
The EFA-10 Fiber Optic Adapter converts the optical data from the field mill to an
electrical signal compatible with your personal computer. Data is transmitted optically
from the field mill at 9600 baud, 8 data bits, 1 stop bit, no parity.
Figure 10: EFA-10 Fiber Optic Adapter
The EFA-10 converts this optical data stream to an electrical signal compatible with your
computer’s RS232 COM port. A USB adapter cable is provided to convert this RS232
signal to USB if a USB connection is preferred.
ST Fiber Optic Connectors
The EFM-100 transmits its data over a fiber optic cable. The fiber optic cable uses St style
connectors on each end.

If the field mill installer is not familiar with ST fiber optic connectors he should familiarize
himself with the connectors on the ground, before mounting the field mill on the roof.
