The external device connector is a Hirose HR 10A-7R-6S female connector. The
pinouts for connecting it to an external device connector are shown below:
CAUTION – Use only the pin connections shown above. Using other connections will
damage the instrument.
CAUTION – The Focus 8 series total station has different pin assignment from other
models of Nikon total station.
To connect to an external power source, supply power to Pin 4 (power terminal) and
Pin 5 (ground terminal) on the instrument. The instrument will use the external power
source even if the internal battery packs are attached.
CAUTION – Make sure that the power supplied is within the rated input range (4.5 V to
5.2 V DC, 1 A maximum). Power supplied outside this range will damage the instrument.
To communicate with an external device, connect the RS-232C signal from the
external device to Pin 1 (input terminal) and to Pin 2 (output terminal) on the
instrument.
Cap the data output/external power input connector securely while not in use. The
instrument is not watertight if the cap is not attached or not attached securely, and
when the data output/external power input connector is in use.
The instrument can be damaged by static electricity from the human body discharged
through the data output/external power input connector. Before handling the
instrument, touch any other conductive material once to remove static electricity.
