The Silex SD-300 and SD-310AN are designed to easily connect and share RS-232 serial devices over a wired or wireless network. Industrial automation, building automation, medical devices, security access and control, point of sale devices, LED signs, bar code/label and other specialty printers, or virtually any other device with a serial port can be now be enabled with secure, robust wired or wireless network capability. It allows flexibility to place the device anywhere on the network instead of needing to be attached directly to the computer, and multiple computers or terminals can access the serial device.Key Features and Benefits:Industry-leading security including WPA, WPA2, and WEP, plus 802.1x authentication with the most commonly used EAP typesDual band IEEE 802.11a/b/g/n support on the SD-310AN allows communication in the 2.4 GHz and 5 GHz bands. Radio interference in the commonly used 2.4 GHz band can be avoided by utilizing 5 GHz.Virtually any client device can remotely control and monitor your serial devices including computers (Windows, Mac, Linux), mobile devices (Android, iOS), and virtual servers (VMware, Citrix, Microsoft Terminal Server and Hyper-V).No special drivers or applications are needed to use the serial devices: Drivers and applications that worked when the serial device is directly connected to the computer will continue to work across the network connected to the SD-300/SD-310AN.SD-310AN provides optimized roaming based on a signal strength algorithm between wireless access points ensuring maximum uptime for the connection.Multiple serial port and wireless modes for maximum flexibility for any environmentSerial Port ModesSerial Port Emulation Mode: The included Silex SX-Virtual Link software precisely emulates a serial port (or COM port) connection on a computer operating system, and then redirects the packets over the network to the serial port of the SD-300/SD-310AN.Raw TCP Connection Mode: This mode makes it possible to possible to directly communicate with a serial device via TCP application program using a TCP socket API.eCable Mode: Serial data can be tunneled over the network between devices connected to SD-300/SD-310AN.Wireless ModesWired Mode: The SD-300 and SD-310AN are equipped with an autosensing 10/100 Ethernet port. SD-300 is wired only. SD-310AN can also operate in wired mode to connect to the Ethernet network.Wireless Station (Client) Mode: The SD-310AN can connect to an existing 802.11a/b/g/n Wi-Fi network. The dual band capability and enterprise security ensure a stable connection to even the most advanced wireless networks.Wireless Access Point Mode: The SD-310AN can create a wireless network so any wireless client (station) can easily make a direct secure connection.
The SD-300 Serial Device Server allows you to connect and share serial devices on a network. Silex offers a reliable way to remotely connect to your RS-232 serial devices.The provided Serial Port Emulator software allows for easy integration with existing PC applications.
