Power
One 3-pin Fischer connector provides the power input interface. Figure 2.3 shows the
pin layout of the power connector. Table 2.3 defines the pinout of the power
connector.
Chassis ground and external ground are not the same for EMI purposes.
CAUTION
The current for the GPS antenna connector is limited to 150mA out of the RF
center conductor. It is short-circuited protected. If using a splitter or other
RF network, use an inner DC block suitable for 1-2 GHz, 50 ohms, maximum
voltage back to the Z-Surveyor cannot exceed 15V.
