X! = Input selection: 1 = composite, 2 = RGB.YUV, and 3 = HDMI
KEY:
X( = Enable or disable: 0 = Off or disable, 1 = On or enable
X2! = On-screen menu timeout: (default = 60 seconds), output sync timeout (default = 501 - never)
0 = OSD never displayed or output sync is instantly disabled with no active input, 1 to 500, in 1 second
increments, 501 = OSD never times out/output sync never times out
X2% = Screen saver mode: 1 = Black screen (default), 2 = Blue screen with OSD text
X3# = Audio gain and attenuation: -18 through + 12 dB, (with leading "+" or "–")
X3$ = Audio Input type:
0 = None, 1 = Analog TRS 1, 2 = Analog TRS 2, 3 = Analog TRS 3, 4 = LPCM-2Ch, 5 = Multi-Ch,
6 = LPCM-2Ch Auto, 7 = Multi-Ch Auto. See the
