Interface converter
TraxBus to EIA-RS232 / EIA-RS485
Transparent communication or with MODBUS ASCII and MODBUS RTU protocols
TraxBus conversion to the following standard physical layers:
• EIA-RS232
• EIA-RS485
TraxInterface4 can drive up to 250 remote peripherals operating in two different modes:
• Transparent
• Modbus® ASCII / RTU
An additional service port is available for monitoring and configuration.
A complete galvanic isolation is provided between local interfaces to fieldbus and power supply.

EIA RS232 – TRAXBUS
Is the easiest way to implement TraxBus when the number of remote peripherals and the system architecture does not require more than 1 TraxBus line. A single master controller is connected to SubD 9 female socket: only RxD, TxD and GND are required.
EIA RS485 – TRAXBUS
EIA-RS485 operates in push-pull action over two lines, allowing the connection of up to 32 transceivers, thus can be used to drive one or more TraxBus lines. A single master controller is connected to SubD 9 female of one or more TraxInterface4.
