Digital Input/Output Expander
Installation Manual
The E-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 E-2D, E-5D, or E-16D Server Environment Monitoring System (SYSTEM).
The E-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).

MOUNTING
The E-DI16DOR16-V2 comes with surface/wall mount tabs on the bottom of the case. These are easily removed and rotated for
attachment to any flat surface. It also includes mounting holes for the installation of rack ear brackets. To mount in a rack as a
single unit, order E-DI16DOR16-V2R to receive hardware for single unit mounting. To mount in a rack as a dual unit, order E-
DI16DOR16-V22R to receive hardware for dual unit mounting.
Follow the instructions below for assembly and installation.
To mount to a wall or other flat surface, remove the screws that secure the mounting tabs, rotate the tabs 180 degrees, and
reinstall the screws.
If the Expander will be mounted as a single or a double, brackets will need to be attached to the case to enable mounting ears or
a connector plate to be attached.
1. Attach the ear brackets to the Expander . The holes in the brackets should line up with pre-threaded holes in the sides of
the Expander. Tighten the screws securely.

3
2. To mount a single Expander in a rack (E-DI16DOR16-V2R), attach the rack mounting ears to the ear brackets using the
#6-32 x 1/4” screws provided. Tighten all screws securely.
3. Install 4 cage nuts (provided) to the rack in locations that line up with the holes in the mounting ears on the Expander.
4. Secure the Expander to the rack using the four #10-32x3/4” screws (not included). Be sure to tighten all mounting screws
securely.
Dual-Expander mounting
To mount a dual Expander in a rack (E-DI16DOR16-V22R), attach the rack ears to the far left side of the left Expander and right
side of the right Expander using the #6-32 x 1/4” screws provided. Install ear brackets in the rear where the two cases will meet.
Then install connector plates to join the two Expanders in the front and rear.

4
Reversible Mounting Assembly
If the Expanders will have the cable connections coming from the rear, the ears and ear brackets can instead be applied to the
back of the Expanders so that the Expanders can be mounted facing the rear. (Install these before attaching the connector plate
to the front.) Once the ear brackets are applied, the ears and connector plates can be attached.

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 E-WSS Wind Speed Sensor).

3a. Digital Outputs on the E-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 “Sensors” list on the summary page as Type "Remote Digital Outputs" in the SYSTEM web interface for assignment to sensor
alert responses.
3b. Output Relays on the E-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 'Sensors" list on the summary page as Type "Remote Digital Outputs" 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 E-DI16DO(R)16.
The SYSTEM will also recognize the number 1 connector set on the E-DI16DO(R)16 as a possible tachometer connector,
displaying a total number of sensors for the E-DI16DO(R)16 as 17. The first two sensors will, by default, be Type "Tach" and
"Remote Digital Input" providing the option to configure the first connector set as either type of sensor.
If a tachometer is being connected (connection "3.1" below), configure the sensor as such. If a water sensor or dry-contact
sensor is going to be connected to connection 1 (connection “3.2” below), ignore the first sensor listing and configure the Digital
Input. Do not configure both ("3.1" and "3.2" in configuration below). If you configure both, the tach configuration will
be ignored.
Notes:
If you configure the Tachometer, and want to change that connection for use with a contact sensor, do not "Delete" the
Tach sensor from the listing, or all sensors and output relays configured for that E-DI16DO(R)16 will be deleted. The
ENVIROMUX will automatically clear all sensors for that expander and reload the defaults. Instead, simply use "Add
Sensor" and add the digital input for that connection ("3.2" in the configuration above). Upon doing so, the Tach input
configuration will be ignored.
Conversely, if you had a contact sensor configured and want to change that digital input to a Tach sensor, be sure to
delete the contact sensor ("3.2" in the configuration above) first.
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 Output Relays, configure them also as described for Output Relays in the manual for the SYSTEM.
To view the status of a connected tachometer, 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 E-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 allExternalSensorsType” (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 “allExternalSensorsType”,
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 allExternalSensorsType 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”.
