Getting Started

Connecting Your ED Device

1. Connect power supply - Provide a minimum of 1.1 Watts with an output voltage between +5VDC and +30VDC to the removable black terminal block. The optional PW-600 and PW-650 power supplies enable the device to be plugged easily into a standard power socket or powered via USB.

   • Using one power supply: connect the positive terminal of the power supply to either +VA or +VB pin and the negative to one of the -V pins
   • Using two separate power supplies: connect one to +VA and -V and the other to +VB and -V. The higher voltage of the two power supplies is selected by the device and in the event of a failure the other supply automatically takes over to keep the device running. The status of the power supply inputs can be monitored visually via a browser from the ED devices home page and also programmatically

   Terminal Block	Pin 1	Pin 2	Pin 3	Pin 4	Pin 5
   Black	-V	+VA	+VB	-V	Func GND

2. Connect to network - Connect the ED device to your local network by plugging an Ethernet cable into the Ethernet port on the device. The ED Ethernet port will automatically detect the polarity of the Ethernet connection so either straight-through or crossover Ethernet cables can be used.

3. Wait for device ready - The LEDs will flash when the power is first applied. When the status LED turns a steady green (after 5-60 seconds) the device is ready to use.

4. IP address assignment - On connecting to the network, the device automatically checks if there is a DHCP server available. If this is the case, the DHCP server will allocate an IP address automatically to the ED device.

5. Fallback IP address - If no DHCP server is detected (e.g. you have the ED device plugged directly into the PC), the ED device will default to an IP address of 192.168.127.254 after 60 seconds. If connecting directly to a PC, make sure the PC is on the same 192.168.127.xxx subnet in order to find your device.

tip

Make a note of device MAC address (on the side of the ED device, 00-0A-4F-XX-XX) as you will need it to identify the device on your network later.

Configuring Your Device Settings

There are four methods to view and configure your ED device. Which method to use depends on personal preference and convenience.

Boost.IO Manager

This is the Windows application that is installed initially to find the device and install the COM port drivers if required. Configuring from here is the recommended option for ease and convenience, as it centralises all Ethernet to Analogue devices in one window. However, not all of the settings of the ED device can be configured from the Boost.IO Manager.

See Boost.IO Manager for more information.

Web Page Interface

This allows the Ethernet to Analogue device to be accessed from any PC within your network as it does not require Boost.IO Manager. Unlike Boost.IO Manager, every setting can be configured using the web configuration pages.

See Web Configuration Pages for more information.

ASCII Protocol

The ASCII protocol is a query-response communication protocol which can be used to set all of the protocol settings of the device, send and read data, and get status information from the devices. To send the commands and receive responses a connection to the device needs to be set up. This can be done using either a TCP connection or through the COM port.

See ASCII Protocol for more information.

Modbus TCP Protocol

Modbus TCP is a standard communication protocol which can also be used to read and write configuration and analogue value data. It uses binary data instead of human-readable ASCII text, and is supported by a wide range of PLCs and data acquisition software. Unlike the ASCII protocol, it allows overlapping requests and connections from multiple controllers.

See Modbus TCP Protocol for more information.

Connecting Analogue Signal Sources to the ED-549

These are not the only ways in which the products may usefully be connected, but the diagrams below show the most common configurations.

Differential (Balanced) Voltage Signal

Connect the positive signal wire to the AIn+ terminal and the negative signal wire to the AIn- terminal. The AGND terminal should be connected to the signal ground at the source.

note

Wiring diagrams for differential voltage connections are available in the original documentation.

Single-ended (Unbalanced) Voltage Signal

Connect the signal wire to the AIn+ terminal and connect the AIn- terminal to AGND. The AGND terminal should be connected to the signal ground at the source.

Current-loop Transducer Signal

For current loop (4-20mA) transducers with external power supply:

• Connect the transducer in series with the power supply
• Route the current through the AIn+ and AIn- terminals
• Ensure the jumper is set to current mode

Current-sink Transducer Signal

For active current-sink transducers:

• Connect the positive supply to the transducer
• Connect the transducer output to AIn+
• Connect AIn- to the power supply ground
• Ensure the jumper is set to current mode

Current-source Transducer Signal

For active current-source transducers:

• Connect the transducer output to AIn+
• Connect AIn- to the signal return
• Connect AGND appropriately
• Ensure the jumper is set to current mode

Connecting Analogue Devices to the ED-560

Single-ended Voltage Signal

Configure the output channel to the 0-10V range and leave the IOut terminal unconnected.

• Connect the VOut terminal to the positive input of your device
• Connect AGND to the device ground

Current-loop Signal

Configure the output channel to the 0-20mA or 4-20mA range and leave the VOut terminal unconnected.

• The ED-560 current output is a 'sink' type
• An external power source is required
• Connect IOut in series with your load and external power supply
• The external power voltage must provide at least 2.8V at the IOut terminal, up to a maximum of 30V

warning

When using current output mode, ensure your external power supply voltage is appropriate for your load. The IOut terminal sinks current from your external supply through your load.
