File Transfer Protocol
Once a bitmap or font file has been created and paired to its command it must be sent using a file
protocol developed specifically for Matrix Orbital displays. Once a file upload command has been sent
requesting a unique reference number and specifying the file size required, the display will respond
indicating whether it has enough room to save the file or not. As is the case throughout the upload
protocol, a response of 1 will indicate confirmation while an 8 corresponds to rejection and will
terminate the session.
