Introducing the E-DIO24
The E-DIO24 is an Ethernet based digital I/O data acquisition device that is compatible with TCP (IPv4 only)and UDP network protocols. The E-DIO24 provides the following features:









24 individually-configurable digital I/O bits
±24 mA drive capability
Software-paced transfer rates up to 5 kHz (typical throughput on a local network)
One 32-bit event counter (shared with a DIO pin)
Remote network access, configuration, and alarm
Screw terminals for field wiring connections
DIN-rail mountable
Functionally equivalent to USB-DIO24 Series and USB-1024 Series hardware.

The E-DIO24 is powered by an external 5 volt power adapter included with the shipment.

Ethernet interface
The E-DIO24 has one built-in 10/100 BASE-T auto-negotiation, high-speed communication port. You canremotely access and configure your E-DIO24 from anywhere on the network. Only one computer can control
the E-DIO24 at one time. The networking protocols are TCP and UDP.
A unique media access control (MAC) address is assigned to each device at the factory. You configure the
Ethernet connection settings through software. A network name in the format E-DIO24-xxxxxx, is assigned tothe device, where xxxxxx represents the lower six characters of the device MAC address.

PreliminaryFunctional block diagram

E-DIO24 functions are illustrated in the block diagram shown here.

Chapter 2

Installing the E-DIO24
UnpackingAs with any electronic device, you should take care while handling to avoid damage from static
electricity. Before removing the device from its packaging, ground yourself using a wrist strap or by simply
touching the computer chassis or other grounded object to eliminate any stored static charge.
Contact us immediately if any components are missing or damaged.

Installing the software
Refer to the MCC DAQ Quick Start for instructions on installing the software on the MCC DAQ CD. Refer tothe device product page on the Measurement Computing website for information about the included andoptional software supported by the E-DIO24.
Install the software before you install your device
The driver needed to run the E-DIO24 is installed with the software. Therefore, you need to install the software
package you plan to use before you install the hardware.

Connecting the external power adapter
Power to the E-DIO24 is provided with the 5 volt, 1 amp external power adapter (PS-5V1AEPS). Connect theadapter cord to the power connector on the E-DIO24, and plug the AC adapter into an electrical outlet.

Preliminary

The Power LED turns on when 5 V power is supplied to the E-DIO24. If the voltage supply is less than 4.2 V
or more than 5.6 V, the POWER LED does not turn on. Refer to Figure 3 on page 11 for the location of thePower LED.

Connecting the E-DIO24

The E-DIO24 requires a TCP and UDP connection to a network or computer.

Using the Ethernet cable provided, connect the E-DIO24 to a 10Base-T- or 100Base-TX compatible Ethernet
port, hub, or switch. When connecting the E-DIO24 for the first time, make sure that you connect to a local
network with DHCP enabled. If you are unsure whether you have access to a local network or that DHCP isenabled on that network, you should connect directly to a Windows PC.
It may take a minute or two for the network DHCP server to detect the device and assign an address. The green
Link/activity LED on the lower left of the Ethernet connector turns on when a valid Ethernet link is established,
and blinks when network activity is detected.
Once the E-DIO24 is physically connected to the local network or PC, you can run the software (InstaCal for
example) to establish a connection. If a connection cannot be established, make sure the device is using thedefault configuration by following the instructions in the Restoring factory default network settings on page 9.
Once a connection is established and you can communicate with the device, you can change the configurationfor other network scenarios.

7E-DIO24 User's Guide

Installing the E-DIO24

Configuring network settings
The following E-DIO24 network settings are software-selectable. One user at a time can connect to the device
and configure network options. The default settings are recommended for typical local networks.

Address mode
The address mode settings determine whether default IP parameters (IPv4 address, subnet mask, and gateway)
are assigned to the E-DIO24, or whether an auto-addressing method is used to assign these parameters.
DHCP or Link-Local enabled (default)
If connected to a network with a DHCP server, the service automatically assigns IP addresses to the E-DIO24.
If the connected network does not have a DHCP server, the address stored in the default IP address is assigned.
If the E-DIO24 is directly connected to a Windows PC or other host that supports link-local addressing, a linklocal address is assigned. A link-local address is valid only for communications between the E-DIO24 and the
PC to which it is connected.
DHCP Only
This setting enables configuration by a DHCP server, if one is available. The E-DIO24 is assigned an IP address
shortly after it is powered up and attached to the network.
Link-Local Only
The E-DIO24 is assigned a link-local IP address by the Windows PC or other host that supports link-local
addressing to which it is connected. A link-local address is valid only for communications between the
E-DIO24 and the PC to which it is connected.
StaticThe default IPv4 Address is manually configured on the E-DIO24.

IP address
The default IP address settings are assigned when automatic addressing is either disabled or not available(DHCP or link-local, for example):

IPv4 address – The IP address stored on the device. The default IPv4 address is 192.168.0.101.
Subnet mask – The subnet mask stored on the device. The subnet mask determines the number of bits of

the IP address that is used for the host portion of the address vs. the number of bits used for the network
portion. The default subnet mask is 255.255.255.000.
Gateway – The gateway IP address stored on the device. The gateway address of the device bridges
subnets within a network. The default gateway is 192.168.0.1.

Connection code
The connection code is number between 0 (default) and 999999999. Change this number from its default toprevent other users from connecting to and configuring the device. When the code is set to a value other than 0,
the device remains visible to other users on the network, but connection by another user is not allowed.

Installing the E-DIO24

Configuring the network router for communication across networks
To communicate with the E-DIO24 from a computer connected to a different network – such as over theInternet – you must change the network configuration of the network router.
Caution! This procedure should only be performed by a network administrator or computer professional.
Incorrect settings can significantly disrupt a network.
Complete the following steps to configure the network router for communication across networks. In thisprocedure, the E-DIO24 is installed on the host LAN, and the computer is installed on the client LAN.
1.

Connect the E-DIO24 to a local network and determine its IP address.
If the address was assigned by DHCP, we recommend that you change it to a static address: set the default
address to the address assigned, and set the device network configuration to a static value.

2.

Configure the firewall/router to forward incoming traffic to the following ports to the IP address assigned
to the device:oo3.

UDP:54211 (discovery)
TCP:54211 (commands)

On the computer connected to the client LAN, enter the WAN address of the host router, and specify theports that were forwarded to connect to the remote E-DIO24.

You can select a different port if the port above is not available on your router; however make sure that thesame port is configured for both UDP and TCP.

Network alarm
You can configure a digital output bit to change state when a host is connected to or disconnected from the
E-DIO24. All alarm settings are selectable with software.

Restoring factory default network settings
The reset button is used to restore the factory default network settings. This button is located next to the LEDs
on the top edge of the enclosure; see Figure 3 on page 11.
To reset network configuration settings to factory default values, press and hold the Factory reset button for atleast four seconds until both the Power and Activity LEDs blink. When you release the button, the device starts
up with network settings restored to the factory default values. If you release the button before the two LEDs
blink, the settings are not affected and the device starts up normally. If InstaCal is open when default settings
are restored, click the Refresh Boards toolbar button to reflect the changes.

Updating firmware
The E-DIO24 firmware can be updated in the field if required. Firmware available for download is posted atwww.mccdaq.com/firmware.aspx. MCC recommends that you check this page periodically to see if an update
to your device firmware is available.

Firmware update mode
If a firmware update fails, you can force the device into firmware update mode and use InstaCal to recover fromthe failure.
To put the device into firmware update mode, press and hold the device reset button and apply power. The
device LEDs will continuously blink. InstaCal will detect a device in this mode as a bootloader device. Run
InstaCal and download the firmware. After downloading the firmware, refresh the device list and add the device
to InstaCal again.

LED status indicators
The E-DIO24 has two LED indicators that indicate the status of power and host communications:

The Power LED is on when external power between 4.2 V to 5.6 V is supplied.
This LED is off when the external power supply is not connected, or the input power is outside of the 4.2 V
to 5.6 V voltage range of the external supply, causing a power fault.
The E-DIO24 has an onboard voltage supervisory circuit that monitors the 5 V external power supply.
The Activity LED is on when a valid host connection is detected.
This LED blinks when a command is received.

Both Power and Activity LEDs blink once when factory default settings are restored. Refer to Restoring factory
default network settings on page 9 for more information.

Ethernet connector
The E-DIO24 has one 10/100 BASE-T, auto-negotiation, high-speed communication port. The port connector isan RJ-45, eight-position type that accepts CAT-5 shielded or unshielded twisted pair cable. The maximum
communication distance without using a repeater is 100 meters (328 feet). You can send your data 100 meters at
data speeds of up to 100 Mbps using only one Ethernet cable connected to the network.
Ethernet connector LEDSThe green Link/activity LED on the left of the connector is on when a valid Ethernet link is established,
and blinks when network activity is detected.
The yellow Speed LED on the right of the connector is on when the transmission speed is 100 Mbps, andoff when the transmission speed is 10 Mbps or no Ethernet link is established.

External power connector
Connect the supplied 5 volt, 1 amp power adapter (PS-5V1AEPS) to this connector. The E-DIO24 requires
external power to operate.

Factory reset button
Use the factory reset button to restore network configuration settings to the factory default values. Refer to
Restoring factory default network settings on page 9 for instructions.
The reset button can also used to put the device into firmware update mode to recover if a firmware update fails.
Refer to Firmware update mode section on page 9 for details.

Signal connections
Digital I/O
The E-DIO24 has 24 DIO lines configured as three 8-bit ports – port 0, port 1, and port 2. Each bit isindividually configurable for input or output. The digital I/O transfer rate is 5 kHz, maximum for softwarepaced operation on a local network.
You can specify a digital bit configured for output as a network alarm and change state when an Ethernet
connection with a host is established or lost. All alarm settings are selectable with software.
The digital I/O terminals can detect the state of any TTL-level input signal with CMOS output. Refer to theschematic shown in Figure 4.

Figure 4. Schematic showing switch detection by digital channel P0D0

If you set the switch to the +5 V input, the digital bit reads TRUE (1). If you move the switch to GND, the bit
reads FALSE (0).
Hardware compatibility
The E-DIO24 is functionally equivalent to USB-DIO24 Series and USB-1024 Series hardware. Software
programs written for those hardware devices can be run with the E-DIO24.
Pull-up/down configuration
All DIO lines are pulled high by default to 5 V through 47 kΩ resistors via jumpers W3, W4, and W5 on thecircuit board (see Figure 5). Each jumper configures a digital port for pull-up or pull-down.

Figure 5. Pull-up/down jumper locations

The pull-up/down voltage is common to all 47 kΩ resistors. Each jumper is configured by default for pull-up.
Figure 6 on page 13 shows the jumper configured for pull-up and pull-down.
Caution! The discharge of static electricity can damage some electronic components. Take care whenremoving the enclosure. Before touching the board, ground yourself using a wrist strap or touch
the computer chassis or other grounded object to eliminate any stored static charge.
