CANRS01

INC, LLC. produces several gateways for CANopen and DeviceNet. The gateways can be ordered with RS232 ports, RS485 ports, or a second CAN port. The device allows the network to connect to legacy devices such as bar code readers and weigh scales. The gateway has two serial ports that can be selected at purchase time. The supported serial types are RS232, RS485, and CAN. Other protocols such as Modbus, J1939, and J1708/1587 that lay on top of these physical mediums are available in different models (see vehicle gateway and Modbus gateway). The serial gateway can be operated in a pass through mode, where the user sends the number of bytes and the raw data to transmit and the device transmits the information to the serial port. The data received on the serial port is converted to the network protocol and the number of byes received and the raw data received are made available on the network. A second mode is also supported that allows the user to configure the gateway to send and receive formatted messages. This mode allows the conversion to be accomplished in the gateway instead of in the controller. The gateway is available in three different enclosures, economical black ABS plastic, Nema 4 aluminum alloy, or Nema 4X polycarbonate. All versions (except with internal screw terminal connections) are potted to help protect against vibration, shock, and foreign matter. The Network connector is available in a standard 5 pin sealed micro connector or a low cost 5 pin Combicon connector with screw flanges. The Combicon connector allows the use of lower cost cabling, and also allows the use of a dual row Combicon plug to facilitate the daisy chaining of modules in the network.
