TagMaster’s RS485 Converter is compact and robust in design for reliable operations in harsh environments. This converter connects an RS232 serial communication line to a 2-wire RS485 multidrop network. It is specially adapted for the communicators and software. The RS485 converter automatically senses the direction of data flow and switches the transmission direction. This control is completely transparent to the user system enabling the use of existing software or other software written for RS232 without the need for any modifications.
The converter is easily mounted on a DIN rail, a wall using the included bracket, or a “piggy-back” where stacking of several units on one another is applied. Ensuring quick and simple installation, modification and maintenance, signal connections are made through rugged plug-in screw terminal blocks. The RS485 Converter accepts any unregulated power source between +10 and +30Vdc. These converters are protected against accidental power supply reversals and can be safely connected or disconnected without causing disturbance to a running network.
