J-Series Connections Layout
Connecting Antennas and RF Feeders
The RF antenna system should be installed in accordance with the manufacturers notes. Antenna gain must be considered when setting Transmit
Power. Refer to Compliance notices at the end of this document and in the use manual for more information.
The RF connectors on this product are TNC Type female connectors. Always use good quality low loss feeder cable, selected according to the
length of the cable run. Ensure all external connections are waterproofed.
Power Supply Requirements
Tx: Nominal 13.8 Volts DC @ 800 mA (Max 1A)
Rx: Nominal 13.8 Volts DC @ 150 mA
Rated Operating Voltage 10 - 30 Volts DC
The J-Series Radio is supplied with the a mating DC power connector:
Phoenix Contact Part Number 1777989. The DC Power connector should be installed with the locking screws done up tightly. Cable must be #22
AWG or larger, 70
o
C min. temperature rating. CSA maximum current rating: 2.5A.
The J-Series Ethernet radio modem will operate from a 10 to 30 volt (filtered) DC supply. The radio is designed to self protect from permanent
damage if the voltage exceeds 30V dc or if reverse polarity is applied. The replaceable internal fuse has a rating 3 Amp.
Fuse: Trio Part No. SM%FUSSQ3A
The current requirement is typically 180mA @ 13.8 V DC in receive mode, and will vary in transmit mode according to RF output power level & duty
cycle. The radio modem can be damaged if there is any potential difference between the chassis-ground, RS232 signal ground, power (-) input, or
antenna coaxial shield.
Before connecting any wiring, ensure all components are earthed to a common ground point (please pay particular attention to 24V PLC power
systems where DC-DC converters are used).
Connect the antenna, Ethernet and RS 232 plugs BEFORE applying power to the unit. Lastly, before inserting the power plug, please re-check that
the polarity and voltage on the DC power plug is correct using a multimeter.
