Operation
Table 2.1 describes the front panel components of the Z-12 Real-Time Sensor.
RF Connector
The RF connector is a standard N-type female receptacle wired for connection via 50-
ohm coaxial cabling to a GPS antenna with integral LNA. The N-type connector shell 
is connected to the Z-12 Real-time Sensor common ground. The N-type connector

Number Component Function
1 Antenna RF connector The RF connector is a standard N-type female 
receptacle wired for connection via 50-ohm coaxial 
cabling to a GPS antenna with an integral LNA. The N-
type connector shell is connected to the Sensor 
common ground. The N-type connector center pin 
provides +9.5 VDC (to power the LNA) and accepts 
1227 and 1575.42 MHz RF input from the antenna; 
the RF and DC signals share the same path.
2 LED LED which provides equipment status. Red indicates 
power is applied. Green flashes indicate the number of 
satellites the Sensor has acquired.
3 On/Off Power Button Turns unit on and off.
4 PWR Connectors Dual power connector which provide connections to 
redundant power sources.
5  Serial Port A
 Serial Port B
 Serial Port C
 A complete RS-232 port with full-handshaking. 
Port A can be used for communications with a 
Husky hand-held computer, an IBM compatible 
PC, or a radio. Port A is used for transferring data 
from the receiver to a computer, from a receiver to 
a receiver, and all other communications to and 
from the receiver.
 A complete RS-232 port with full-handshaking. 
Port B can be used for communication with the 
Husky hand-held computer, an IBM compatible 
PC, or a radio. Port B is used for transferring data 
from the receiver to a computer, from a receiver to 
a receiver, and all other communications to and 
from the receiver.
 An abbreviated RS-232 port that has flow-control 
only. Port C can only be used for input/output of 
RTCM differential corrections.
