Security Notes
X-320M™ does not employ a general purpose computer operating system and does not have features
such as telnet, FTP, SSH, nor uncontrolled open ports. This means it is not possible for someone to
‘break in’ to X-320M™ and access other devices on your local network. The simplicity of X-320M™
makes it an inherently secure device. evertheless, as with any device installed on a network,
appropriate security precautions should be observed.
If X-320M™ is installed on the Internet, it is recommended that passwords be enabled for the Control
Page. Passwords should be at least 8 characters in length and use a combination of upper and lower
case letters and numbers. For additional security, a firewall may be used to limit access to selected IP
addresses. Another option may be to set up a Virtual Private etwork (VP ) between the network where
X-320M™ resides and the client machine (web browser, another, ControlByWeb™ product, etc.).
Final Installation Notes
This ControlByWeb™ product supports connection to 10 Mbps and 100 Mbps networks. Although 100
Mbps networks are faster, the amount of data transferred to and from this device is very minimal and
little, if any, performance increase will be gained by setting it to 100 Mbps. There are advantages,
however, to operate this device at 10 Mbps. At 10 Mbps, less power is required, the unit runs cooler, and
the lifetime of the product will be extended.
Any changes to the Ethernet settings will require a removing and re-applying power to X-320M™.

adapter, or POE Injector and Splitter. Verify that the adapter is rated for the operating current of X-
320M™ (See Appendix G: Specifications for current requirements.)
Note: Vin- should be tied to Earth ground.
Multiple X-320M™ units may be connected to a single power supply by connecting the power supply
input terminals in parallel. The power supply must have a high enough current rating to power all units
connected. (See Appendix G: Specifications for current requirements.)
Page 16 Xytronix Research & esign, Inc.

X-320M™ User's Manual Installation and Setup
2.2.2 Digital Input/Output Connections
The Digital I/O's can be individually programmed to function as either inputs or outputs. When
configured as inputs, pull-up or pull-down resistors can be programmed. For unconnected inputs, the
pull resistors will be read as O when pulled up, or OFF when pulled down.
Input Connection
The inputs can be configured to count the tips of the bucket in a rain collector, the rate of spin on a wind
speed sensor, or detect switch closures on other connected devices, such as a lightning detector.
Pull-Up/Pull-Down Resistors
Weak pull resistors are used to control the state of the inputs when they are unconnected, such as when
connected to an open switch. Devices that use a switch contact, such as rain buckets, require the input
to be configured with a pull-up resistor. One side of the contact is connected to I/O 1 or I/O 2, and the
other side is connected to Gnd. When the bucket in a rain collector tips, the contact is momentarily
closed, causing the input to pulse OFF. This pulse increments the rain bucket counter.
Pull-down resistors are similar, but this configuration is typically not applicable for common weather
sensors.
Xytronix Research & esign, Inc. Page 17

Installation and Setup X-320M™ User's Manual
Output Connection
The digital outputs can be used for controlling external devices. The digital outputs have limited drive
capability, but can be used with solid state relays to control larger loads.
Relays on other ControlByWeb devices can be controlled with X-320M through the Remote Relay
feature. Up to two remote relays can be configured, each of which may be on a separate device.
Applications for the digital outputs and remote relays include:
Activate external audible alarm or lights in cases of high wind, temperature, lightning detection, or other
sensor levels.
Deactivate pumps or irrigation system during high wind, rain, or freezing temperatures.
Disconnect sensitive equipment when lightning is detected.

2.2.3 Analog Input
Voltage and current output sensors can be connected to X-320M analog inputs. Typical weather station
analog sensors can measure temperature, humidity, solar radiation, barometric pressure, and soil
moisture.
Additionally, the analog inputs can function in a digital mode, activating alarms based on voltage
thresholds. Many stations may use both digital inputs for wind or rain sensors. An analog input may be
available for such things as water (flood) or lightning detection.
*Switch state signals can be used with analog inputs to trigger actions using voltage level alarms.
Xytronix Research & esign, Inc. Page 19
Figure 2.2c - Analog Input Connections

Installation and Setup X-320M™ User's Manual
Wiring Considerations
The analog inputs on X-320M™ are very sensitive (10 uV) and can be affected by low level noise. The
Vin- on X-320M™ should be connected to earth ground. Additionally, all cable shields should be
connected to earth ground. Users should observe single-point ground strategies, typical of
instrumentation systems.
Proper grounding may be accomplished by connecting the grounding cables to either the AC mains
ground or to the station ground.
High Output Sensors, > 5 VDC
In the case of a sensor whose output levels are higher than 5 volts, a simple voltage divider can be used
to scale down the output. The following diagram shows a simple voltage divider circuit. In the example,
Vin can range from 0 to 10 volts and resistor values for R1 and R2 will be chosen so that Vout will have
a range that falls within the 0 to 5 volt range of the Analog Input.
Generally, you can choose a 1 kΩ resistor for R2 and then calculate the value of R1 using the following
formula.
Vout=Vin∗( R2
(R1+R2))
To determine the proper resistor value to use in the example above, use the maximum output of the
sensor (10 VDC) as Vin in the equation, the maximum input value of the the Analog Inputs (5 VDC) as
Vout, and R2 = 1 kΩ. Solving for R1 gives 1 kΩ.
R1 = 1 kΩ
R2 = 1 kΩ
As another example, if the maximum output voltage of the sensors is 15 VDC, choose R2 = 1 kΩ and by
solving the equation, R1 = 2 kΩ.
