Datasheet-ID:  SR-D User Manual RemoteCOM w/ Wi-Fi (C30 - C32) Introduction Serial Port Server w/ Wi-Fi® (C30 - C32) Serial Port Server is a complete hardware and software solution for creating remote communication ports. The software part can be uploaded to any of the Redisage C30 - C32 Ethernet Converters. It provides a communication between a LAN host and a device equipped with RS232/RS485 serial interfaces. A dedicated app makes it easy and fast to configure and deploy. There is a possibility to create virtual COM ports with the Redisage Configurator to minimize number of cables. Onboard Wi-Fi module makes it even more versatile and independent solution. Configuration by the Web Page Serial Port Server w/ Wi-Fi® (C30 - C32) This page presents capabilities of the Ethernet Converters configuration. First of all, make sure that converter is connected to power supply and to the LAN using a patch cord. If the device has not static IP set up, it will be necessary to obtain its IP address in the local network. User interface is mostly similar for every converters but some subpages might be diffrent for several models depends on amount of interfaces. In order to avoid some issues, click on a “Help” button in the top right corner on every page. Default configuration Default configuration of the Ethernet Converters: IP address: 192.168.100.100 Subnet mask: 255.255.255.0  Gateway: 192.168.100.1 DNS 1: 192.168.100.1 DNS 2: 8.8.8.8 Default login details: User name: admin Password: admin123 Login To access the web page open the browser, type IP address of the converter (default is 192.168.100.100 ). Then log in using user’s personal credentials. If it is a first configuration or the converter had a factory reset, then use default login details (login: admin , password: admin123 ). The configuration is available only if devices are connected to the same Local Area Network as the computer used for it. Status page After a successful login, there should be an insight to important information such as port status, service and port which are in use and more details about the connection. Changing username or password After clicking “Edit User” under the user icon, it is possible to change the username or the password. If login details were forgotten, it would be necessary to do a factory reset via a USB/UART converter and a serial console. Ports page This page allows configuring the device’s ports. There is a toggle switch next to a “Port” label by which it is possible to turn ON/OFF any particular ports. Item Description Service RemoteCOM The RemoteCOM option lets to attach the port to a computer running the Redisage Configurator as if it would be physically present in the computer. TCP Socket TCP/UDP Socket exposes this port as a regular network socket - connect to this socket with own software and write/read data to send/receive data over the serial port without any additional software or serial port handling. UDP Socket Port The service number - the device has an “IP Address” by which it is identified and a couple of services running on it. It's required to tell the device which service should be in use by entering this device's IP address and the port number in the RemoteCOM client or user’s software. Connection Timeout [s] The time specifying how often (every how many seconds) the "keep alive" packet will be sent to check if the client is still connected. Value 0 means that the connection is kept permanently without any timeout. Inactivity Time [ms] The maximum allowed time in milliseconds during which there is no data transfer. When connection is inactive for the time longer or equal to the entered value, then it will be closed. Value 0 means there is no measure of the inactivity time at all. Encryption Determine how the data is protected 'in flight' over a network. It is available only with the RemoteCOM service. Once enabled, it is necessary to set the password. Password Protect the communication between the device and various clients - keep it secret! Same settings have to appear in clients - without the correct passwords, a client will not be able to connect at all. Termination Enable/disable termination on the RS line. Baud Rate Determine the port's transmission speed over the data channel. Data Bits Determine the number of data bits in the port's message frame. Parity Enable/disable parity check in the port's message frame. Stop Bits Determine the number of stop bits in the port's message frame. Notes These notes are for information only - feel free to write down anything related to this port (device it connects to, etc.). They're also shown in the Configurator during the device discovery - in the other words, they're public. Changing port’s service closes all sockets connected to the ports. In the UDP mode, port number 15051 is reserved for UDP broadcast service. Network page In this section, network settings can be changed according to target LAN parameters. Item Description Configuration Method Enable/disable the DHCP server. If the DHCP server is disabled, the IP address of the device has to be set manually. IP Address IP address of the device. Netmask Netmask associated with the IP address. Gateway Gateway address currently used by the device. MAC Settings Allow setting the default MAC address or typing it manually. MAC Address Allow changing the physical address of the device. Item Description HTTP Port Determine the port of the control panel. Telnet Port Allow connection with the device via Telnet. Broadcasts Notify RemoteCOM clients in the same network about this device's existence. With this enabled, the Configurator will automatically set most of the settings correctly after picking the correct port. Hostname Label that is assigned to the device. DNS Address 1 (Primary) Primary Domain Name System used by the device. DNS Address 2 Domain Name System used by the device. It is possible to obtain a dynamic IP address. Just switch configuration method from static IP to DHCP (automatic). This process may cause some issues with identifying converters in LAN unless there is an access to the device which is responsible for allocating IP addresses. Keep in mind that in case of changed IP address user needs to type new IP in the address bar and log in again. Device page On the device page there are tools used to a firmware update, a factory reset and a device reboot. Item Description Firmware Update Update firmware. Factory Reset Restore default ports settings and default network configuration. Reboot Reboot the device. Firmware update The device firmware update must not be interrupted. Update the device only if experiencing issues, being instructed to do so by our support or requiring the latest features/bugfixes. Failure during the update may 'brick' the device and make it unusable. Use the remote-com-esp32.fir file for a firmware update. Factory reset To restore default settings, press the “Factory Reset” button. After that, user will be asked to type “RESET”. Then it will take a few seconds to reload the web page and restart the device. Configuration by the Telnet Console‎ Serial Port Server w/ Wi-Fi® (C30 - C32) The device can be also configured via the Telnet Console. Firstly, make sure that converter is connected to the power supply and to the LAN using a patch cord. Knowledge of the device’s IP address (default is  192.168.100.100 ) and Telnet port number (default is 23 ) is necessary to establish a connection. Use command below in a terminal window to connect to the device: telnet If the connection is successful there will be a login prompt visible. Log in using user’s personal credentials or the default login details (login: admin, password: admin123). If login is successful, it will be possible to start typing configuration commands. The configuration is available only if devices are connected to the same Local Area Network as the computer used for it.

To get more details about every particular command, append “help” after each commands (example: "ipconfig help"). Redisage Configurator‎ Serial Port Server w/ Wi-Fi® (C30 - C32) Redisage Configurator is an app used to emulate connection between converter and a PC as if its RS232/RS485 ports would be connected directly to the COM port. The advantage of that functionality is lack of additional cables. Transmission can be tested over Ethernet. First connect the device to a local network using the Ethernet port and power it up. During the configuration process set “Service” to the RemoteCOM option on the “Ports” page. While changing port service from RemoteCOM to TCP/UDP Socket make sure to disable RemoteCOM virtual port in the Redisage Configurator first. Redisage VSP Driver In order for Redisage Configurator to work properly, it is necessary to install the Redisage VSP Driver. It can be done with RedisageVSPDriver Installer available for Windows. You can download it for free here . Redisage Configurator When the device is configured open the Redisage Configurator app. Use the “Add Device” button to set up a new connection with a device. On the right side there should be a list of available devices visible. Choose one of them or specify a custom COM port number, an IP address and a service port number. While specifying a custom virtual COM make sure to use the same IP address and service port as set earlier in the port configuration. In order to establish a connection with a desired device use the “Enable” button. To end the connection use the “Disable” button. Service IP/hostname, service port and password can be modified at any time. There are also available 2 options of the encryption methods (none (disabled) or strong (AES-GCM 128-bit, Argon2)) and 5 options of the connection timeout (brief, short, fair, modest or lengthy). Changes have to be saved with “Save Changes” button. There is also the “Settings” tab at the top of the window from where the Logging Directory or the Device Manager can be opened. If everything is connected properly there should be a new COM port available in the Device Manager. It is also possible to check it, for example, on the web page. If any change is made to the port configuration, make sure to apply it with the “Save Changes” button. Troubleshooting If a discovered device cannot be added, check if it hadn’t been added before with a different COM port / service port. In that case, delete previous configuration from the Redisage Configurator. If that doesn't work, check if the port service was configured correctly for the RemoteCOM Service. Modes of Operation RemoteCOM Serial Port Server + Wi-Fi (C30 - C32) TCP Socket Mode Serial Port Server w/ Wi-Fi (C30 - C32) This article presents a simple instruction of a first connection between a TCP client and a RS232/485 device through the RemoteCOM Serial Port Server. Firstly, connect the RemoteCOM according to the diagram below. Then, it is necessary to configure the RemoteCOM’s ports. It can be done, for example, via the device’s web page. Ports' configuration can also be done via the Telnet, serial or service console. Set the “ TCP Socket ” option in the “Service” field on the “Port” page. Check also if the port number is set correctly in the “Port” field. Set desired options of the RS232/485 connection (“Baud Rate”, “Data Bits”, “Parity”, “Stop Bits” - these options should be the same as in the RS232/485 device). Now, the device should be ready to work. Once the TCP Client creates a TCP socket, the bidirectional communication should be available. Test connection Connection can be easily tested with a USB-RS232/485 converter and for example Hercules Setup Utility  software. Connect the RemoteCOM’s RS232/485 port to the USB-RS232/485 converter and plug it in to the USB port of a PC. Open Hercules Setup Utility program and go to the “Serial” page. Set serial connection options according to the previous RemoteCOM’s ports configuration and open the COM port. Then, go to the “TCP Client” page and set the device’s IP address and port. After a successful connection, there should be the bidirectional communication available. UDP Socket Mode Serial Port Server w/ Wi-Fi (C30 - C32) This article presents a simple instruction of a first connection between a UDP client and a RS232/485 device through the RemoteCOM Serial Port Server. Firstly, connect the RemoteCOM according to the diagram below. Then, it is necessary to configure the RemoteCOM’s ports. It can be done, for example, via the device’s web page. Ports' configuration can be also done via the Telnet, serial or service console.  Set the “UDP Socket” option in the “Service” field on the “Port” page. Check also if the port number is set correctly in the “Port” field. Set desired options of the RS232/485 connection (“Baud Rate”, “Data Bits”, “Parity”, “Stop Bits” - these options should be the same as in the RS232/485 device). Now, the device should be ready to work. The bidirectional communication should be available after the device receiving a first message from the UDP client. Before that happens, all the data sent from the device to the UDP client will be buffered and sent later. Test connection Connection can be easily tested with a USB-RS232/485 converter and for example Hercules Setup Utility software. Connect the RemoteCOM’s RS232/485 port to the USB-RS232/485 converter and plug it in to a USB port of a PC. Open Hercules Setup Utility program and go to the “Serial” page. Set serial connection options according to the previous RemoteCOM’s ports configuration and open the COM port. Then, go to the “UDP” page and set the device’s IP address and port. The bidirectional communication should be available after the device receiving a first message from the UDP client. Before that happens, all the data sent from the device to the UDP client will be buffered and sent later. Redisage Configurator Virtual COM Mode Serial Port Server /w Wi-Fi (C30 - C32) This article presents a simple instruction of a first connection between a virtual COM port and a RS232/485 device through the RemoteCOM Serial Port Server and the Redisage Configurator app. Redisage Configurator is used to emulate connection between converter and a PC as if its RS232/RS485 ports would be connected directly to the COM port. The advantage of that functionality is lack of additional cables. Redisage Configurator can be installed on Windows machine and requires the Redisage VSP Driver to work (it can be installed with RedisageVSPDriver Installer).  In order to perform a setup, connect the RemoteCOM according to the diagram below (RemoteCOM should be connected via Ethernet to the same local network as the PC). Then, it is necessary to configure the RemoteCOM’s ports. It can be done, for example, via the device’s web page. Ports' configuration can also be done via Telnet, serial or service console.  Set the “RemoteCOM” option in the “Service” field on the “Port” page. Check also if the port number is set correctly in the “Port” field. Additionally, encryption can be set to increase the security (it will also require to set up a password). Next, open the Redisage Configurator and click the “Add Device…” button. Available RemoteCOM’s ports should appear on the list. Choose the desired one and click the “Add” button. If a discovered device cannot be added, check if it hadn’t been added before with a different COM port / service port. In that case, delete previous configuration from the Redisage Configurator. If that won’t work, check if the port service was configured correctly for the RemoteCOM Service. Enable the virtual COM port with the “Save changes” button. If a password was set during the configuration, it will be necessary to type it into the “Password” field. Now, the device should be ready to work. The bidirectional communication should be available from the start. It is possible to check if created virtual COM port is present in the system. Just go to the “Settings” page and choose “Open Device Manager” button. There should be a “Redisage” COM visible. Test connection Connection can be easily tested with a USB-RS232/485 converter and for example  Hercules Setup Utility  software. Connect the RemoteCOM’s RS232/485 port to the USB-RS232/485 converter and plug it in to a USB port of a PC. Open 2 instances of Hercules Setup Utility program and go to the “Serial” page of the first one. Set serial connection options according to the previous RemoteCOM’s ports configuration and open the COM port (fixed options: Baud Rate 115200; Data Bits: 8; Parity: None; Stop Bits: 1). Then, go to the “Serial” page of the second Hercules instance and set the virtual COM port in the same way as the serial port of the first Hercules instance. After a successful connection, there should be the bidirectional communication available. While changing port service back from RemoteCOM to TCP/UDP Socket make sure to disable RemoteCOM virtual port in the Redisage Configurator first.

TCP Socket TCP/UDP Socket exposes this port as a regular network socket - connect to this socket with own software and write/read data to send/receive data over the serial port without any additional software or serial port handling. UDP Socket Port The service number - the device has an “IP Address” by which it is identified and a couple of services running on it. It's required to tell the device which service should be in use by entering this device's IP address and the port number in the RemoteCOM client or user’s software. Connection Timeout [s] The time specifying how often (every how many seconds) the "keep alive" packet will be sent to check if the client is still connected. Value 0 means that the connection is kept permanently without any timeout. Inactivity Time [ms] The maximum allowed time in milliseconds during which there is no data transfer. When connection is inactive for the time longer or equal to the entered value, then it will be closed. Value 0 means there is no measure of the inactivity time at all. Encryption Determine how the data is protected 'in flight' over a network. It is available only with the RemoteCOM service. Once enabled, it is necessary to set the password. Password Protect the communication between the device and various clients - keep it secret! Same settings have to appear in clients - without the correct passwords, a client will not be able to connect at all. Termination Enable/disable termination on the RS line. Baud Rate Determine the port's transmission speed over the data channel. Data Bits Determine the number of data bits in the port's message frame. Parity Enable/disable parity check in the port's message frame. Stop Bits Determine the number of stop bits in the port's message frame. Notes These notes are for information only - feel free to write down anything related to this port (device it connects to, etc.). They're also shown in the Configurator during the device discovery - in the other words, they're public. Network page Item Description Configuration Method Enable/disable the DHCP server.
