Designed for applications where a digital display needs to communicate with an automation system, computer, or other network-connected equipment, the adapter provides a practical interface between Ethernet communication and the display.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This custom configuration demonstrates how the DC-25 Serial to Ethernet Adapter can be used to remotely control a four-digit DC-25 display. Instead of requiring direct local interaction with the display, formatted commands can be transmitted over the network to change what the display shows and how it operates.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Password-Protected Web Configuration<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The DC-25 Serial to Ethernet Adapter includes a web-based configuration interface that provides access to the device&#8217;s network and automation settings. The network settings page is protected by a password, helping restrict access to configuration functions.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The password can be changed through the interface, allowing the administrator to establish a customized password for the adapter. A device name can also be assigned. This name appears on the adapter&#8217;s homepage and can help identify the unit when multiple network-connected devices are being used.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The Ethernet configuration provides options for different network environments. The adapter can be configured to obtain its network information automatically through DHCP or can be assigned a static IP address when a fixed network address is required.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Network information available through the interface includes:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Device name<\/li>\n\n\n\n<li>IP address<\/li>\n\n\n\n<li>MAC address<\/li>\n\n\n\n<li>Ethernet configuration<\/li>\n\n\n\n<li>Communication settings<\/li>\n\n\n\n<li>Automation settings<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">These configuration options provide the flexibility needed to incorporate the adapter into different network architectures.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">TCP or UDP Network Communication<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The DC-25 Serial to Ethernet Adapter is designed to receive formatted command packets over the network. TCP communication is used by default with a listening port of 23, while UDP communication can also be selected when required by the application.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This allows the adapter to serve as a communication point between a network-connected control system and the DC-25 display. Once the appropriate network settings are configured, commands can be sent to the adapter to control the display.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The communication method can therefore be selected based on how the display will be incorporated into the customer&#8217;s existing system.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Formatted Commands Control Display Functions<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">A major feature of the DC-25 Serial to Ethernet Adapter is its command-based operation. The adapter uses a defined command protocol that allows specific functions of the connected display to be controlled through formatted network messages.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A command string can be entered through the web interface, and the supplied command documentation provides the available commands for the particular configuration.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The command protocol can be used for functions such as:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Adjusting display brightness<\/li>\n\n\n\n<li>Setting a time of day<\/li>\n\n\n\n<li>Operating a count-up timer<\/li>\n\n\n\n<li>Operating a countdown timer<\/li>\n\n\n\n<li>Providing countdown end-of-period indication<\/li>\n\n\n\n<li>Controlling relay functions on applicable configurations<\/li>\n\n\n\n<li>Displaying static numbers<\/li>\n\n\n\n<li>Incrementing displayed numbers<\/li>\n\n\n\n<li>Decrementing displayed numbers<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">The command structure allows the same basic display platform to be used for multiple applications, depending on how the customer needs the display to operate.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Adjustable Digital Display Brightness<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The adapter can send commands that control the brightness of the connected display. Brightness can be adjusted across a range, allowing the display intensity to be matched to the surrounding environment or application.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For example, a brightness command can be configured with a value from 0 through 10. A setting of 05 provides approximately half of the available brightness range.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This provides another level of control for applications where display visibility needs to be adjusted without physically accessing the display.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Network-Controlled Time of Day Display<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The DC-25 Serial to Ethernet Adapter can also be used to control a DC-25 display as a time of day clock. A time command can be transmitted through the network to set the display to a specific hour, minute, and associated AM or PM setting.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This provides an option for systems where the time displayed needs to be controlled by another network-connected device rather than manually set at the display.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The network command interface can therefore make the DC-25 suitable for applications requiring centralized or automated time control.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"1919\" height=\"1063\" src=\"https:\/\/dc-digital.com\/wordpress\/wp-content\/uploads\/2026\/09\/DC-25SerialDataUnit.jpg\" alt=\"\" class=\"wp-image-8414\" srcset=\"https:\/\/dc-digital.com\/wordpress\/wp-content\/uploads\/2026\/09\/DC-25SerialDataUnit.jpg 1919w, https:\/\/dc-digital.com\/wordpress\/wp-content\/uploads\/2026\/09\/DC-25SerialDataUnit-767x425.jpg 767w, https:\/\/dc-digital.com\/wordpress\/wp-content\/uploads\/2026\/09\/DC-25SerialDataUnit-1536x851.jpg 1536w\" sizes=\"auto, (max-width: 1919px) 100vw, 1919px\" \/><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\">Count-Up and Countdown Applications<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Beyond displaying the time of day, the DC-25 Serial to Ethernet Adapter provides access to count-up and countdown functions on compatible displays.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A count-up application can be used when the display needs to track elapsed time or another increasing value. Countdown operation can be used when a predetermined period needs to be displayed and monitored.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Depending on the display configuration, countdown operation can also include end-of-period indication or relay activation. Relay-equipped versions can be configured for applications where an external device or process needs to be triggered when a countdown reaches its end.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This makes the network interface useful for applications where timing functions need to be incorporated into a larger automated process.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Static Number Display and Counter Functions<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The command protocol also allows the connected display to operate as a static number display. Values can be sent to the display and can also be incremented or decremented through network commands.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This functionality provides another way to use the DC-25 in applications where a changing numerical value needs to be displayed.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For example, a network-connected control system could send updated values to the display as part of a counting or monitoring process. Rather than using the display exclusively as a timer, the same hardware can be repurposed as a network-controlled numerical display or counter.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Command Documentation for Integration<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The DC-25 Serial to Ethernet Adapter is supplied with command documentation describing the available protocols and commands. The exact command documentation can vary depending on the configuration of the particular unit.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Some DC-25 configurations can include relay functions, while others may not. Relay-equipped versions can provide additional control options, including relay operation associated with countdown functions.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The command documentation provides the information needed to format the network messages correctly for the specific display and adapter configuration.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Flexible Network Interface for DC-25 Displays<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The DC-25 Serial to Ethernet Adapter provides a way to extend the functionality of a compatible DC-25 digital display by adding network-based control. With a password-protected configuration page, DHCP or static IP support, TCP or UDP communication, and a defined command protocol, the adapter can be incorporated into a wide variety of networked applications.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The ability to control brightness, time of day, count-up and countdown functions, static numbers, and counter values gives the DC-25 Serial to Ethernet Adapter flexibility beyond simple display communication.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For industrial automation, commercial equipment, timing systems, counting applications, or other installations where a digital display needs to receive commands over an Ethernet network, the DC-25 Serial to Ethernet Adapter provides a configurable interface for connecting the display to the customer&#8217;s existing network and control system.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">DC-Digital manufactures digital LED displays and custom display solutions designed around the requirements of individual applications. The DC-25 Serial to Ethernet Adapter demonstrates how a standard digital display platform can be customized with network communication capabilities to provide additional control and integration options.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Visit <a href=\"https:\/\/dc-digital.com\/store\/index.php\" data-type=\"link\" data-id=\"https:\/\/dc-digital.com\/store\/index.php\">DC-Digital website<\/a><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><a href=\"https:\/\/dc-digital.com\/store\/contact-us.php\" data-type=\"link\" data-id=\"https:\/\/dc-digital.com\/store\/contact-us.php\">Contact us<\/a> to ask about our customized products!<\/p>\n","protected":false},"excerpt":{"rendered":"<p>See similar product: DC-Version-3.0-Upgrade The DC-25 Serial to Ethernet Adapter provides a flexible way to connect a compatible DC-25 digital display to an Ethernet network and control its functions through network-based commands.
