Abstract
A system and method for data transmission between an intelligent electronic device (IED) and a device, such as a remote display or input/output (I/O) device, are provided. Each data line of the IED is input into a serializer and transmitted over a serial link to a deserializer and then provided to the inputs of remote device, such as a remote display or input/output (I/O) device. The serial link can be made of any media such as copper, fiber optics, etc. The serial link can be formed as one, two or more channels.
