	The '''''main mux''''' is the huge black thing in the [[AV rack]]. It routes video to different places, and also has analogue TV demodulator inputs. It's controlled by an outboard box which sits on the Director/Vision Mixer's desk.		The '''''main mux''''' is the huge black thing in the [[AV rack]].

 A new PIC, a PIC18F2455 using a 20MHz crystal, has replaced this PIC through use of an extra 'daughter' board. This change in PIC was to allow easier coding, using C instead of assembler, and to provide USB capabilities. The source code has also been lost.
-Six 74HC595 shift registers are daisy chained together to form a single large serial-to-parallel converter to control all of the LEDs and the buzzer. The data is shifted in in the following order, with high to turn the LED/buzzer on:
+It now runs on an installed Arduino, and is one of the first [[YVP_Protocol|YVP Protocol]] compatible devices. This does mean a computer is needed to control it however, connected to the now real, RS-232 compliant serial port on the back.
