3.3 SMA CONNECTORS AND LEDs
3.3.1 SMA Antennas connection
The RF-Gate Terminal uses SMA CONNECTORS for ANTENNAS.
RF Antenna: In RF 433Mhz use the 433Mhz ANTENNA with 2dB gain or more.
In RF 2.4Ghz use the 2.4Ghz ANTENNA with 2dB gain or more.
CELLULAR Antenna 4 band 3G ANTENNA with 2.5dB gain.
GPS/RF2 Antenna ACTIVE GPS ANTENNA with 25-28dB gain. (in RFN-SMART915-4NQ-
x0z, RFN-SMART433-4NQ-x0z is used for cellular Antenna diversity)
3.3.2 LED indications
Upon power on, the designated LEDs should act as follows
•CELLULAR_B LED Modem Status, when On the Cellular Modem is ON
oFast blinks (around 2 per second) - search for cellular network
oSlow blink (every 2 sec) - connected to a cellular network
•CELLULAR_A LED turns on when it is connected to the communication server
o2 seconds Slow Blink (200ms ON/1800ms OFF) Low Network Search
o2 seconds Slow Blink (1800ms ON/200ms OFF) modem in IDLE
oFast blink 4 per second, Data Transfer is Ongoing
oAlways High, Voice calling (not in USE)
•RF LED
oIn STAR versions
▪RF_B LED blinks on RF activity
▪RF_A LED blinks when moving the data between the RF and the Smart or
3G Module
oIn Receiver versions
▪RF_B LED blinks when receiving an RF tag data transmission
▪RF_A LED blinks when moving the data to the Smart or 3G Module
oIn Coordinator Versions
▪RF_B LED blinks means the RF is not configured
▪RF_B LED steady ON coordinator is on
▪RF_B LED steady ON coordinator is in Boot Loader
▪RF_A LED always off
