GPS ANTENNA PORT
— Coaxial connector (SMA-type) for
connection of a GPS receiving antenna. Provides 3.5 Vdc output
for compatibility with powered (active) GPS antennas. Do not
short this connector, as you might cause damage to the internal
power supply. The GPS receiving antenna’s gain must be
16 dBi or less.
NOTE:
GPS functionality is required on all Access Points and
Remotes
except when “Free Run” single-channel (non-frequency
hopping) operation is used, which might be possible in some
low-interference environments.
• WiFi A
NTENNA PORT
—
Coaxial connector (SMA-type) for
attachment of a WiFi antenna. WiFI is typically used for short
range wireless communication at the transceiver site or within a
small area around the site.
•
RX2 ANTENNA PORT
— Coaxial connector (TNC-type) for
attachment of a second receiving antenna used in space diver-
sity arrangements.
•
TX/RX1 ANTENNA PORT
— Coaxial connector (TNC-type) for
attachment of the main station antenna (transmit and receive).
2.7 STEP 6: CHECK FOR NORMAL
OPERATION
Once the data equipment is connected, you can check the transceiver for
normal operation.
Observe the LEDs on the top cover for the proper indications. In a nor-
mally operating system, you will see the following LED indications
within 45 seconds of start-up:
•
PWR
—Lit continuously
•
LINK
—On, or blinking intermittently to indicate traffic flow
•
LAN
—On, or blinking intermittently to indicate traffic flow
