Frame Ground FG

Electronic circuits are constantly prone to electrostatic discharge ESD.
Rediisage 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 referece drawing.

If earth ground is not availabe FG can be left floating or can be connected with power supply GND.

Configuration 
Internal Modbus Address is qualified by Gateway/Router as a request for internal resources. Internal Modbus Address has a higher priority than Gateway Slave Address.
Idle Time [s] determines the time thread waits for the TCP connection. If time expired, the connection and thread are closed. Used only in Gateway Mode.
Ports Configuration 
Uart Mode defines the port's role in the system. In Gateway Mode port is used to communicate with Modbus Slave. However, in Router Mode port is used to communicate with Modbus Master. Note the Routing Configuration section below if Router Mode is chosen.
Uart Protocol determines the protocol used for communication.
Gateway Slaves addresses of Modbus Slave Devices connected to Gateway UART ports. Multiple addresses can be written in one field, e.g. 9;11;14-17;80. This field is available only in Gateway Mode. Use * to select all not assigned addresses.
Saves Response Timeout [ms] specifies how long the Device will wait for a response from Modbus Slave.
Baud Rate determines the port's transmission speed over the data channel.
Data Bits determine the number of data bits in the port's message frame.
Parity enables/disables parity check in the port's message frame.
Stop Bits determines the number of stop bits in the port's message frame.
Termination enables/disables termination on the RS line.
Routing Configuration 
Routing Slaves addresses of Modbus Slaves connected to Modbus Router. Multiple addresses can be written in one field, e.g. 9;11;14-17;80. Use * to select all not assigned addresses.
Slaves Response Timeout [ms] specifies how long the Device will wait for a response from Modbus Slave.
IP/Hostname determines IP address or Hostname of Modbus Slave.
TCP Port determines TCP port of Modbus Slave.

Fig. 5. Ports page

Network setting can be changed on the network page.

Hostname is the label that is assigned to the Device.
Configuration Method enables/disables the DHCP server. If the DHCP server is disabled, the IP Address of the Device has to be set manually.
IP Address of the Device.
Netmask associated with the IP Address.
Gateway address currently used by the Device.
DNS Address is the Domain Name System used by the Device.
MAC Settings allows setting the default MAC address or typing it manually.
MAC Address allows changing the physical address of the Device.
Services 
HTTP port determines the port of the control panel.
Telnet Port allows connection with the device via Telnet.
Modbus TCP listening port uses as an entry point for new Modbus TCP connections.

Configuration by Serial Console

The device has the ability to be reconfigured via a serial console. C20-C23 and C30-C32 require a dedicated USB/UART converter connected to the USB micro-B connector on the front of the device. C23-C25 can be directly connected to a PC through a USB cable.

Procedure to enter serial console mode on C20-C23 and C30-C32:

  • Turn off the power of the device
  • Connect PC to the C1 micro-USB port using a dedicated USB/UART converter
  • Press and hold the S1 button (or connect Din pin to GND pin if the button is not mounted)
  • Turn on the power and wait a few seconds until the orange LED lights up
  • Release the button (or disconnect Din pin from GND pin)

Procedure to enter serial console mode on C23-C25:

  • Install STM32 Virtual COM Port Driver on your PC
  • Turn off the power of the device
  • Connect PC to the C1 micro-USB port using a USB cable (or use dedicated USB/UART converter)
  • Press and hold the S1 button
  • Turn on the power and wait a few seconds until the yellow CN LED lights up
  • Release the button (or disconnect Din pin from GND pin)

Once this is done you can connect to the serial port. The baud rate of the serial port is 115200. Log in using the default username and password, then change the network settings using ipconfig command.
