2.1 Radio Hardware
The RLX-IFHE radio consists of the following components:
 One antenna port (page 56)
 LEDs that indicate the status of the radio (page 69)
 Ethernet Port (page 59)
 Serial cable ports (page 58)
 Power connection (page 56)
2.1.1 Radio power requirements
The RLX-IFHE radio accepts voltages between 10 and 24 VDC, with an average
power draw of less than 6 watts. A detachable power connector comes with the
radio, as shown. The connector terminals are labeled + (positive DC connection)
and - (DC ground connection). You can use the provided AC-to-DC power supply
adapter that is pre-wired with a power connector, or you can use power from
another source, for example the power supply for the PLC or the networked
devices.
The DC power wires must be less than 3 m to meet regulatory requirements.

2.1.2 Connecting antennas
Each radio must have an antenna connected to the Main antenna port on the
radio; without an antenna for each radio, the network will not function.
All antennas for radios that communicate directly with each other should be
mounted so they have the same antenna polarity. Small antennas with a reverse-
polarity SMA connector can be mounted directly on the radio. Screw the antenna
onto the antenna port connector until it is snug.
Larger antennas and antennas that do not have a reverse-gender SMA
connector must be mounted separately and connected to the radio using a
coaxial antenna cable. Because the antenna cable attenuates the RF signal, use
an antenna cable length that is no longer than necessary to ensure optimum
performance.
Important: If the radio is to be used in a hazardous location, the radio must be
mounted in an enclosure approved for hazardous locations. The radio requires a
separate cable connection to the SMA connector that leads to an internal
antenna.
