External Control Device Setup * All data are transmitted by Hexadecimal code *Two/One part Channel: 6th bit This bit is used in a cable-ready system. *Using physical channel: 5th bit If the channel band is NTSC air or NTSC cable, channel tuning can be done by only physical channel. In this case, using physical channel bit must be low(0). But if the channel band is ATSC air or ATSC cable, there are two cases that physical channel enable or disable. If the physical channel sending is meaningful, you should set this bit low(0). If the physical channel sending is meaningless, you should set this bit high(1). Example) 1.
