Incotex 221 / Mercury 221

 
 

Description:

USB interface converter into CAN/RS-232/RS485, designed for connection to PC of one or some energy meters with built-in interfaces CAN/RS-485 or devices with interface RS-232. interfaces: USB <-> CAN, RS485, RS232

 Functions:

«Mercury 221» represents converter of interface USB to CAN/RS-232/RS-485 and designed for connection to PC of one or some meters “Mercury” with built-in CAN/RS-485 or RS-232 (which use only RX. TX) interfaces. After installation of USB driver the device is detected as virtual COM port. Driver installation manual and the drivers themselves are provided on CD. Connection circuit of meters to PC is given in meters operation manual. Converter board contains jumper X4 in order to set converter operation mode (with jumper – “ECHO” CAN, without jumper – without “ECHO” RS-485). Factory setting – with jumper. “ECHO” – returning to converter the bite transmitted from PC (controller, etc). All converter interface outputs have galvanic decoupling from PC USB interface.
