Introduction
C01 - C04 family products are reliable M-Bus electrical standard converters. They enable communication in master mode with up to 10 simultaneously connected slave devices. Dedicated EMC integrated circuits guarantee improved connection quality by limiting the impact of interferences typical for an industrial environment.

Passive vs. Active RS232
Devices equipped with a passive RS232 interface do not include an internal voltage converter. 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 - MBus10 Converter to RS232
C02 - MBus10 Converter with active RS232 interface
C03 - MBus10 Converter to RS485
C04 - MBus10 Converter to RS232/RS485 with active RS232 interface
In the C04 gateway user should 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.
