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.
