Waveguide Radar - RADAC WaveGuide 5 Direction User Manual

WaveGuide radar

A cable gland (IP68-10bar and IP69K certified) is
pre-installed on the WaveGuide sensor for use on the
terminal compartment as a watertight cable entry
point. The supplied gland allows the installation of
insulated cables from 8 to 15 [mm] in diameter.
When selecting a cable for use with a WaveGuide
system, the following specifications must be used:
• Two wires for power transmission, the choice
of power supply will influence the diameter
and insulation thickness of those wires.
• Four wires for data transmission, at least sat-
isfying Category 5e Ethernet cable (Cat 5e)
specifications.
• The cable must be shielded and can have a
maximum length of 80 [m].
Upon request, Radac can supply an optional cable
that complies with the WaveGuide system require-
ments for power and data transmission.
The terminal compartment contains a six pole and
a two pole connector as well as a ground connection
point, as shown in Fig. 2.2. The six pole connector
is used to connect the Ethernet data wires. The
poles labeled with Tx+, Tx-, Rx+ and Rx- relate to
RJ45 pins 1,2,3 and 6. Additionally a reset function
is implemented on the top two poles, which should
only be temporarily connected when resetting the
radar to its factory settings or setting a fixed IPV4 address.
The 2nd connector (2 pole connector) in the terminal compartment is used to supply the
system with either 24-65VDC or 65-240VAC power. The poles are labeled as +/~ and -/~,
yet the internal power supply operates also when the + and - poles are switched around.
Please do take into account the voltage drop due to wire resistance between the power
supply unit and the radar, the radar must at all times receive more than 21.0 VDC. For
this reason, to be sure to stay within the limits, at longer distances it is advised to use a
36VDC or a 48VDC power supply.
The cable shielding must be connected to ground at both ends of the cable.
