	Description	Baldor proprietary CAN interface using a RJ45 connector.

CAN2 is opto-isolated and is intended for use with Baldor’s ioNode family of CAN peripherals. Practical operation of this CAN channel is limited to 500Kbaud owing to the propagation delay of the opto-isolators.

Correct operation of CAN2 can only be achieved with screened/shielded, twisted pair cabling. CAN2+ and CAN2- must form a twisted pair with the shield connected to the connector backshell. CAN2 must be terminated with a 120Ω resistor connected between CAN2+ and CAN2- at both ends of the network and nowhere else.

If the MintDrive is at the end of the network then ensure that the CAN2 DIP switch (located on the front panel), is in the ‘ON’ position, which will connect an internal terminating resistor.

The CAN2 port must be powered with a DC voltage in the range 12-24V. This can be achieved by powering an ioNode family device. Note that on the ioNode jumpers JP1 and JP2 must be in the CAN Bus 2 position as this selects pins 7 & 8 for CAN traffic.
