Zone 1 and Zone 2 volume control Hex string's (xx)=(level)
For example setting Zone 1 volume to level 48: in ASCII #aV48, in Hex: 23 61 56 34 38
Volume adjusting by steps: $xGUP is a RS232 command for volume increasing by one step, $xGDW for volume
reducing by one step x = zone number. Please use “a” instead x for zone 1 and“b”for zone 2
For example:
Zone 1 volume increasing by two steps send $aGUP command twice: in ASCII $aGUP, in Hex: 23 61 47 55 50
Zone 2 volume increasing by two steps send $bGUP twice : in ASCII $bGUP, in Hex: 23 62 47 55 50
