Data Sheet 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. C30 C31 C32 Features Ethernet converter to RS232/RS485 ESD protection for the RS485 data line Power supply: +12 to +30 VDC Transmission speed up to 115200 bps Tx, Rx and power LED indicators RS485 embedded termination 120 ohm WiFi 802.11b/g/n 150 Mbps / 2.4 GHz Operating temperatures: -40°C to +75°C DIN rail mounting Dimensions: 90x56.4x22.5 mm 3 years warranty Customization of OEM is welcomed Introduction C30 - C32 are a products family of reliable converters based on the  ESP32 Xtensa LX6 microcontroller, extending the capabilities of industrial devices. The addition of a network interface allows remote access and full control over a communication via a computer. The user performs the basic configuration of transmission parameters in a browser or via a Telnet/serial console.  Dedicated EMC integrated circuits guarantee improved connection quality by limiting the impact of the interferences typical for an industrial environment.

It means, don't use pairs: RS232-1 & RS485-1 at the same time and RS232-2 & RS485-2 at the same time! Frame ground FG Electronic circuits are constantly prone to electrostatic discharge ESD. Redisage Electronics modules feature a design for the frame ground terminal block FG. The frame ground provides a path for bypassing ESD, which provides enhanced static protection ESD abilities and ensures the module is more reliable. Connecting FG terminal block to the earth ground will bypass the ESD disturbances outside the device so will provide a better level of protection against ESD. Frame Ground FG connection reference drawing is provided below. If earth ground is not available FG can be left floating or it can be connected with the power supply GND.

Check user manual before first launch. Reset to Factory Defaults Reset to factory defaults is possible on the web page in the device section or using the service mode.  Service mode Procedure to enter service mode for C30 - C32 converters Turn off the power of the device. Connect Ethernet converter to the dedicated USB/UART converter via the microUSB port. Connect the USB/UART converter to the PC. Open the serial console (default baud rate is 115200 bps). Short the DI and GND ports. Turn on the power. Wait until the ST indicator ( red LED) lights up. Open the the DI and GND ports. If the process is successful, service commands can be typed into the terminal. List of commands in the service mode Command Description help Print the help. credits Print current credits value for this device. dev_ident Print the device identification value. restart Restart the system. serial_num Print the serial number of this device. version Display the bootloader version. xmodem Download image to the internal flash using xmodem. defaults Reset application variables to defaults. ipconfig Print or change the network configuration. flash_read Read bytes from flash memory. md Read bytes from memory address. In the service mode, the “ipconfig” command can only show a last static IP address. Additional notes Wi-Fi® is a registered trademark of Wi-Fi Alliance®.
