The present invention discloses a remote control device. Via the present remote control device, a remote computing device can operate a plurality of computing devices and further administrate the whole system constituted by the plurality of computing devices and a KVM switch via a network. The remote control device and the method used therein firstly generates a menu in response to a request from the remote computing device, and the menu has at least one option for a remote control action. The menu is then transmitted to the remote computing device via the network. Once a cursor position representing a chosen option is received from the remote computing device via the network, the cursor position corresponds to the option. The remote control action is carried out according to the cursor position.
