Not only is a web UI supported (as in previous generations), but also this new Windows application may be used to change settings and recover modules
with an unknown IP address. New firmware upgrade options are now available, allowing users to upgrade firmware as new features are released.
Ethernet Relay Control
Introducing the NCD5500 Ethernet to Serial Converter. NCD's 3rd Generation Converter setting new standards for reliability, low-cost, and ease of use! Connect the complete line of NCD Industrial Devices to your Ethernet Network using this modular communications module from NCD. Based on the their next generation Ethernet to Serial Converter, the NCD5500 was customized specifically for use with NCD devices to ensure optimal compatibility with our complete line of products. This Ethernet communications module essentially converts TCP/IP data into serial data bytes, and sends these bytes to the complete line of NCD devices via Serial Communications. This Ethernet communications module is suitable for use with endNode, ProXR*, ProXR Lite*, Fusion, Reactor*, and Taralist* series controllers as well as a broad range of IoT connected devices. This Ethernet to Serial Communication Module is also Compatible with Alpha Station and Base Station, Making it Easy to Discover the IP Address.

Ethernet to Serial Communications Module
This Ethernet to Serial Communications Module converts TCP packets to Serial data and vise versa. This device can be configured to automatically close the socket after a programmable timeout or to leave the socket open. A blue LED light indicates an open socket connection. Program the Baud Rate of this Device from 9600 to 115.2K Baud and communicate to this device over the default TCP port 2101. This device also supports Static IP Addresses, DHCP, and has the ability to recover back to factory default settings with a simple press of a button!
DHCP and Static IP Addresses
This module supports both DHCP and static IP Addressing. For communications reliability, especially via Remote Access, we recommend using a Static IP Address when you feel comfortable doing so. This will ensure that the device will always be where you expect it to be when you try to connect to it.
The main method of communication to the Ethernet modules is a standard TCP Socket. This communication protocol makes use of Network Sockets to create point to point tunnels that data can flow through bi-directionally. In this way the computer that is controlling the relay can send commands and shortly thereafter receive the response through the same Socket.
3rd Generation Hardware Now Shipping
This is NCD's 3rd generation hardware for Ethernet to Serial communications, representing giant steps forward in reliability, easy of use, recover-ability, and LOW COST. Yes, we are actually LOWERING the price of this device as costs have shrunk considerably from previous generation Ethernet to Serial conversion technologies. Other significant improvements include new recovery options. Not only is a web UI supported (as in previous generations), but also a new Windows application may be used to change settings and recover modules with an unknown IP address! New firmware upgrade options are now available, allowing users to upgrade firmware as new features are released.
When using this board over the internet and outside the Local Area Network, Port Forwarding will be required. Port Forwarding is a protocol used by your router to allow incoming requests for connections to get through to a specific device on a specific port. Below is an example of how it works. In this example a router has been setup to forward incoming requests for port 2101 to the device at the IP Address 192.168.2.19 on port 2101. Now when any device that tries to access this Port on the External IP Address the router will see the request and automatically forward the request to the device at the IP Address of 192.168.2.19 on port 2101. If this Port Forwarding rule was not in place and a request came in on port 2101 the router would not know which port or device to forward it to and the request for connection would be denied. Note: Port Forwarding will not be necessary when using this within a Local Area Network. For more on Port Forwarding with detailed instructions for every router visit: https://portforward.com/ .
Base Station Software is available at no charge to get you up and running fast (more on Base Station below). Once powered up, the controller waits for a ProXR command. A command consists of a few bytes of data in numerical format (ProXR Enhanced Command Set) usually between 2 and 6 bytes. Once the command has been received, the controller processes the command, and sends you back ASCII character code 85 to signal the completion of your command. If a command was sent to read the status of the relay the status is sent back.
Perhaps the most overlooked aspect of relay control is proper handling of inductive loads. Inductive loads can best be defined as anything with a magnetic coil, such as a motor, solenoid, or a transformer. Controlling a inductive load using this relay controller requires the use of induction suppression capacitors. The purpose of this capacitor is to absorb the high voltages generated by inductive loads, blocking them from the contacts of the relay. Without this capacitor, the lifespan of the relay will be greatly reduced. Induction can be so severe that it electrically interferes with the microprocessor logic of our controllers, causing relay banks to shut themselves down unexpectedly. In the case of Ethernet devices, customers may experience loss of communications until the device is reconnected. Capacitors that we offer are available at checkout, for more information view our Induction Suppression Video.
