Abstract

A method for detecting a type of one of plurality of devices attached to a graphics machine, each device being one of at least a first type and a second type. The method includes detecting at a controller the type of device attached to or to be attached to the machine. The controller is capable of preadjusting the device or machine as a function of the detection. A graphics machine includes a controller, a first device connected to the controller, the first device being categorizable as one of at least a first type and a second type, the controller detecting the type of the first device, and a memory accessible by the controller, the memory storing information regarding the first type and the second type.

Claims

1. A graphics machine comprising:

a controller;

a first device connected to the controller, the first device being categorizable as one of at least a first type, a second type, and a third type, the controller detecting whether the first device is of the first type, the second type or the third type; and

a memory accessible by the controller, the memory storing information regarding the first type and the second type and the third type;

wherein the controller automatically adjusts the first device as a function of the information;

the first device includes a type identifier, and the machine further comprises an identifier reader connected to the controller;

the type identifier is a plug having an input power pin and at least one other pin, the first type or second type being identified by a connection between the power pin and the other pin; and

the at least one other pin includes two other pins, the type being determined by the presence or absence of power at the other pins when power is supplied to the input power pin.
