In this case, the connected external device must supply the necessary voltage to drive the RS232 data lines. This means the RS232 port is functional only when connected to a host device capable of providing the required signaling levels. In contrast, devices with an active RS232 interface feature an integrated voltage converter that generates the appropriate RS232 voltage levels internally. As a result, the data lines are powered by the converter itself, ensuring proper signal levels regardless of the capabilities of the connected device. Variants C01 - M-Bus10 Converter to passive RS232 C02 - M-Bus10 Converter with active RS232 interface C03 - M-Bus10 Converter to RS485 C04 - M-Bus10 Converter to RS232/RS485 with active RS232/RS485 interface In the C04 gateway user can use only RS232 or only RS485 interface of one port as they occupy the same internal bus of the device. 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.
