Configuration by the Serial Console‎ Modbus Ethernet Gateways (G01 - G03 & G14 - G16) Another way to configure the device is via a serial console. In case of the G01 - G03 Modbus gateways an additional USB/UART converter is needed. Procedure to enter serial console mode on G01 - G03 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). Press and hold the S1 button. Turn on the power. Wait until the ST indicator ( orange  LED) lights up (it should light up after red light - service mode). Release the S1 button. Login using user’s personal credentials or default login details. If the process is successful, configuration command can be typed into the terminal. Procedure to enter serial console mode on G14 - G16 Install STM32 Virtual COM Port Driver. Turn off the power of the device. Connect Ethernet converter directly to the PC (the dedicated USB/UART converter is not obligatory). Open the serial console (default baud rate is 115200 bps). Press and hold the S1 button. Turn on the power. Wait until the ST indicator ( yellow  LED) lights up. Release the S1 button. Login using user’s personal credentials or default login details. If the process is successful, configuration command can be typed into the terminal.

Modbus ports configuration commands modbus modbus help Print command help. modbus int_addr VALUE Set internal Modbus address. Example: modbus int_addr 5 modbus idlet VALUE Show or set the idle TIME (in seconds) of the TCP connection after which the TCP connection is terminated by the converter and the TCP socket is released. Example: modbus idlet 720 If a subcommand that normally sets a value is not given an argument, it will print the current value. Example: modbus idlet Set idle time is 5000 modbus_ports modbus_ports help Print command help, does not require com_number. modbus_ports PORT_NUMBER add_slaves [SLAVE_ADDR ;/- SLAVE_ADDR, *] Set all addresses of slaves connected to com_port. A star in value means fill rest free slaves. It means all slaves that are not set to other ports will be set to this one. Example: modbus_ports 1 addslaves 124 Example: modbus_ports 1 addslaves 12-124 Example: modbus_ports 1 addslaves 12;14;18 Example: modbus_ports 1 addslaves 12;14-17;150-200 Example: modbus_ports 1 addslaves 12;14-17;150-200, * modbus_ports PORT_NUMBER show_slaves Show addresses of slaves connected to com_port.

Example: modbus_ports 1 baud 9600 modbus_ports PORT_NUMBER bits [CPS] Set bit count to C, parity to P, and stop bits to S. Valid values are: C: 7, 8 or 9 P: N, E or O (N- none, E- even, O- odd) S: 1 or 2 Example: modbus_ports 1 bits 8N1 Example: modbus_ports 2 bits 7O1 modbus_ports PORT_NUMBER state [GATEWAY/ROUTER/DISABLE] Enable or disable uart functionality.  Example: modbus_ports 1 state GATEWAY Example: modbus_ports 2 state DISABLE modbus_ports PORT_NUMBER termination [on/off] Enable or disable termination on RS485 port.  Example: modbus_ports 1 termination on modbus_ports PORT_NUMBER slave_response_timeout TIMEOUT Set response timeout (serial slave) in ms. When this timeout expires, delayed frames are dropped. Example: modbus_ports 1 slave_response_timeout 2000 If a subcommand that normally sets a value is not given an argument, it will print the current value. Example: modbus_ports 2 baud Set baud rate is 115200 PORT_NUMBER is a number of ports in modbus gateway and it is counted from 0. modbus_routing modbus_routing help Print routing's help. modbus_routing show Display all active routing table in system. [LP]: [SLAVES NUMBERS] [IP/HOSTNAME] [PORT] [TIMEOUT] modbus_routing add SLAVE_ADDR HOSTNAME PORT TIMEOUT SLAVE_ADDR with HOSTNAME PORT is used by uarts working in Modbus router mode. TIMEOUT (in ms) is used to close the connection if a slave is not responding. The maximum records is 8. One record for one address/ip. Example: modbus_routing add 18 192.168.0.10 502 2000 Example: modbus_routing add 18;25 192.168.0.10 502 2000 Example: modbus_routing add 18-25 192.168.0.10 502 2000 Example: modbus_routing add 18-25;* 192.168.0.10 502 2000 Example: modbus_routing add 18-25 modbus.local 502 2000 modbus_routing remove [HOSTNAME_NUMBER/all] Remove Modbus Routing Table record. HOSTNAME_NUMBER is line number from /show/ command. Example: modbus_routing remove 2 Example: modbus_routing remove all Network settings The following commands might be helpful to change network settings according to target LAN parameters,  ipconfig ipconfig addr ADDRESS Set IP address to ADDRESS.

Service mode Procedure to enter service mode for G01 - G03 gateways 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). Press and hold the S1 button. Turn on the power. Wait until the ST indicator ( red  LED) lights up. Release the S1 button. If the process is successful, service commands can be typed into the terminal. Procedure to enter service mode for G14 - G16 gateways Install STM32 Virtual COM Port Driver (if it was not done before). Turn off the power of the device. Connect Ethernet converter directly to the PC (the dedicated USB/UART converter is not obligatory). Open the serial console (default baud rate is 115200 bps). Press and hold the S1 button. Turn on the power. Wait until the ST indicator ( red  LED) lights up. Release the S1 button. 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. In the service mode, the “ipconfig” command can only show a last static IP address. Factory reset To restore default settings, type “defaults”. After that, user will be asked for type “default network” to reset the network settings as well. Then user will be informed if the process is successful. Default login details: - login: admin - password: admin123 - IP: 192.168.100.100 Additional notes In order to avoid issues like connecting to host, type “help” to get more information. To get more details about every particular command, append “help” after each commands (example: "ipconfig help").
