Operation
The voltage input range is 10-32 volts, with a power rating of 12 watts.
Serial Port Configuration
The Sensor provides three RS-232 serial ports with two-way full-duplex
communication. Ports A and B are full-capability RS-232 ports used with external
devices such as a handheld controller, PC, or modem. Port C is a restricted capability
RS-232 port used for RTCM differential in/out, communication link (radio), or reset
plug. Three male DB9 connectors provide the interface for the three RS-232 channels.
Pin 9 of port A is used for the 1 PPS interface. Pin 9 of port B is used for the event
marker. Figure 2.4 shows the DB9 pin configuration.
WARNING
Do not connect or disconnect power or signal cables from the Z-12
Real-Time Sensor while power applied. Possible injury and equipment
damage may occur.
