ENVIROMUX-DI16DO(R)16
Digital Input/Output Expander
Installation Manual
The ENVIROMUX-DI16DO(R)16 Digital Input/Output Expander enables the connection of up to 16 additional digital sensors and
output devices using just one RJ45 Sensor port on an ENVIROMUX-2D, ENVIROMUX-5D, or ENVIROMUX-16D Server
Environment Monitoring System (SYSTEM).
The ENVIROMUX-DI16DO16 includes digital outputs with an open-collector design for the control of up to 16 relays, solenoids,
LEDs, and other devices that operate at voltages between 0-24VDC (maximum 500mA).
The ENVIROMUX-DI16DOR16 includes digital outputs with a normally-open SPST relay design for the control of up to 16 different
devices that operate at a maximum125VAC (0.5A maximum) or maximum 30VDC (1.0A maximum).

Installation
1. Connect the Expander to the SYSTEM using up to 500 feet (152.4 m) of 18-24AWG CAT5, 5e, or 6 cable.
2. Dry contact sensors can then be connected to the
Expander using 26-16AWG wire. Up to 16 sensors
can be connected.
Two-wire switch-only type sensors can be connected to
the plus (+) and ground ( ) terminals of each of 16 sets
of terminals.
Terminal pair 1 is specially designed for connection of
a tachometer/anemometer with a range of 0-255Hz (like
the ENVIROMUX-WSS Wind Speed Sensor).

3a. Digital Outputs on the ENVIROMUX-DI16DO16 have an open-collector design for the control of up to 16 relays, solenoids,
LEDs, and other devices that operate at voltages between 0-24VDC (maximum 500mA). Devices connected to Digital Outputs
will display in the “Remote Output Relay” list in the SYSTEM web interface for assignment to sensor alert responses.
3b. Output Relays on the ENVIROMUX-DI16DOR16 have a normally-open SPST relay design for the control of up to 16 different
devices that operate at maximum 125VAC (0.5A maximum) or maximum 30VDC (1.0A maximum). Devices connected to
Output Relays will display in the “Remote Output Relay” list in the SYSTEM web interface for assignment to sensor alert
responses.

Web Interface- Summary Page
The Summary Page of the SYSTEM will display sensors connected to the ENVIROMUX-DI16DO(R)16 in a separate list labeled
“Remote Digital Inputs”. (The image below demonstrates the summary page with two ENVIROMUX-DI16DO16 Digital
Expanders connected.)
The SYSTEM will also recognize the number 1 connector set on the ENVIROMUX-DI16DO(R)16 as a possible tachometer
connector, displaying its status under “Sensors”. If a tachometer is being connected, configure the sensor as such. If a water
sensor or dry-contact sensor is going to be connected to connection 1 (Connection “1.1” or “2.1” below), ignore the listing under
“Sensors” and configure the listing under “Remote Digital Inputs”. Do not configure both.

When configuring the Remote Digital Inputs for connection to a water sensors or dry-contact sensors, configure them just as you
would any other Digital Input as described in the manual for the SYSTEM.
When configuring the use of Remote Output Relays, configure them also as described for Output Relays in the manual for the
SYSTEM.
To view the status of a tachometer connected to Digital In #1, Click on the Sensor description or click on “View”
The status page for the sensor will open, displaying the default value of the sensor with a 0-255Hz range of sensing operation.
To configure the sensor for specific use, click on “Configure” to open a page with variable values (see image on next page).
Most of the sensor settings are the same as any other sensor configuration (detailed in the SYSTEM manual) but there are some
differences:
Sensor Settings Description
Associate Sensor Select if the Type “DIO” should be replaced by the sensor type to be entered in the next box.
Associated Sensor Type Enter the “Type” of sensor that should be displayed on the summary page and in all alert
communications received regarding this sensor
Associated Sensor Unit Enter between 1 and 3 alphabetical characters. (Ex. MPH for Miles Per Hour) These
characters will be used by the ENVIROMUX to represent the unit of measure reported by the
attached sensor. Leaving it empty will result in an empty string in the reported data. For
example, a value will be reported on the status page, but no unit of measure will be displayed.
SNMP Associated Type ID Enter ID value from MIB file if SNMP traps will be used for alert notifications for this sensor (for
more on this, see “SNMP Custom Type ID” on next page)
Min. Associated Level The minimum range of the units to be associated with the cycle count measured from the
attached sensor.
(Ex. the ENVIROMUX-WSS associates one rotation within 1 second to be a wind speed of
2.5MPH. With an maximum operating range of 255Hz (or cycles), the maximum wind speed
measurement will be 637.5MPH (255Hz X 2.5MPH).)
Max. Associated Level The maximum range of the units to be associated with the current reading measured from the
attached sensor.

SNMP Custom Type ID: Use this field if SNMP traps will be used for alert notifications. The Type ID corresponds with a value
defined in the MIB file under “extSensorType” (default value is 32567 for type “Custom”). Place the desired number in this box
that represents the type of sensor to be reported in the MIB browser or SNMP trap.
To define a new type of sensor;
1. open the MIB file,
2. locate the section titled “extSensorType”,
3. assign a description and a number not already in use (in the “SYNTAX” field) to associate with it ,
4. enter the number for the newly defined extSensorType in the SNMP Custom Type ID box.
If the Type ID is left blank, the value “0” will be assigned, which will be reported in the browser and SNMP trap as type
“undefined”.
