Binary Mode 1 (SW7-1:ON, SW7-2:ON, SW7-3:Any)
It displays the hexadecimal data as sent with entering space between 1Byte data.
It can display 10Byte in 1 screen. It scrolls 1 line when it received 11Byte of data.
(example） URTH?TX = 0x01; TXWait();
URTH?TX = 0x02; TXWait();
・・・・・・・・・・
URTH?TX = 0x0A; TXWait();
