It must be considered that this supply is not isolated with respect to CANbus or RS485. Therefore, if 

the system contains other devices that have a non isolated power-supply, MMIMYK must have a 

dedicated supply.

RJ11

The connection through RJ11 to an MCX supplies power to MMIMYK and provides directly the 

CANbus connection.

USB

MYK can be supplied with power from the host USB port. Since current consumption can be high 

make sure that the port is of “high-current” type and can supply up to 500 mA as from USB 2.0 

specification. The USB port on MMIMYK is galvanically isolated with respect to the fieldbus 

connections.

Mounting

MMIMYK can be conveniently mounted into a DIN-rail.

The cabinet where MMIMYK is mounted should be mainly vibration free in order to avoid problems 

on the USB connector or memory card.
