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.
