2.1.6 DC-IN Connector
The ES-R-2x01-M is supplied with an external +5V, 10W DC power supply. It is recommended that the
ES-R-2x01-M is only used with this power supply.
If an alternative power supply is used it must be a +5V +/-5% DC supply capable of providing at least
1A. The DC-IN connector accepts a DC Jack with a 2.1mm pin and a 5.5mm barrel with +5V on the
centre pin. There is no reverse voltage protection.
The Yellow PWR LED is illuminated when power is applied to the ES-R-2x01-M.
