Table 2.6: Z-FXHE Rear Panel Description
Component Function
Power Connector Allows external power source.
SS Radio Connector Allows RF connection of the embedded Spread Spectrum Radio
Receiver Board to the Spread Spectrum Antenna TNC reverse
polarity.
Port 1 includes ports A &
C functions
Port 2 includes ports B &
D functions
Each port delivers a 12V output on pin 1 for Radio Modem Power
Up. the total power delivered by all connectors is 1A, at 50% duty
cycle, 250ms duration. In case of a short-circuit, the power is
internally fused—the fuse has been tripped requiring the removal of
the short-circuit prior to activation of this power.
• 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 C can be
used for communication with the Husky hand-held computer, an
IBM compatible PC, or a radio. Port C 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.
Port 1 also carries a 1PPS output on pin 10.
• 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.
• A complete RS-232 port with full-handshaking. Port D can be
used for communication with the Husky hand-held computer, an
IBM compatible PC, or a radio. Port D 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.
When the internal Spread Spectrum Radio is installed, this port is
disabled.
Port 2 also carries an Event Marker Input on pin 10.
External Frequency
Reference connector Allows input of external reference clocks
Input frequencies: 5MHz, 10MHz, or 20 MHz sinusoidal
Input Power Range: 10 dBm to 20 dBm.
