The default that most devices use/accept is: Baud Rate - 9600 Data Bits - 8 Parity - None Stop Bits - 1 Com Port Pin Configuration: Use standard pin configuration. A configuration that allows direct connection to a PC via 9-pin straight through serial cable is best. Use of only 3 pins(Transmit, Receive, Ground)is best. 9 pin female D connector Pin 2 = Transmit Pin 3 = Receive Pin 5 = Ground RS-232 interface : Commands are to be sent to the unit via RS-232 using the following format: = = = 0x0d = 0x30,0x30 Status Byte: Upon receiving the command and done, a single status byte will be transmitted The format for the status byte is : = = 0x31,0x30,0x30 RS232-Interface Usage Details: The RS-232 interface has a first-in-first-out (FIFO) buffer which will allow each commands to be received in direct succession. Commands are executed in the order in which they are received with approximately a 1/2 second delay between each command. If a longer string of commands is necessary, a minimum of 1/2 second delay should be added before sending additional commands. Example for sending a long string of commands: [Command 1] [Command 2] [Command 3] If receiving the errors data, a single status byte will be transmitted. The status byte is: Rs232 = ASCII = <0x45,0x58,0x58> Upon Receiving the Command and done a Single Status byte will be transmitted Command description Rs232 Command ASCII Command Status Command Description Rs232 Commanc ASCII Command POWER ON 00 0x30,0x30,0x0d Take unit out of standby 100 0x31,0x30,0x30 POWER OFF 01 0x30,0x31,0x0d Put unit in standby 101 0x31,0x30,0x31 TRAY OPEN/CLOSE 02 0x30,0x32,0x0d Tray open 102a 0x31,0x30,0x32,0x41 Tray close 102b 0x31,0x30,0x32,0x42 PLAY 03 0x30,0x33,0x0d Play 103 0x31,0x30,0x33 PREVIOUS 04 0x30,0x34,0x0d Previous 104 0x31,0x30,0x34 PAUSE 05 0x30,0x35,0x0d Pause 105 0x31,0x30,0x35 STOP 06 0x30,0x36,0x0d Stop 106 0x31,0x30,0x36 NEXT 07 0x30,0x37,0x0d Next 107 0x31,0x30,0x37 REVERSE 08 0x30,0x38,0x0d Reverse 108 0x31,0x30,0x38 FORWARD 09 0x30,0x39,0x0d Forward 109 0x31,0x30,0x39 NUMBER KEY PAD 1 0A 0x30,0x41,0x0d Number Keypad 1 10A 0x31,0x30,0x41 NUMBER KEY PAD 2 0B 0x30,0x42,0x0d Number Keypad 2 10B 0x31,0x30,0x42 NUMBER KEY PAD 3 0C 0x30,0x43,0x0d Number Keypad 3 10C 0x31,0x30,0x43 NUMBER KEY PAD 4 0D 0x30,0x44,0x0d Number Keypad 4 10D 0x31,0x30,0x44 NUMBER KEY PAD 5 0E 0x30,0x45,0x0d Number Keypad 5 10E 0x31,0x30,0x45 NUMBER KEY PAD 6 0F 0x30,0x46,0x0d Number Keypad 6 10F 0x31,0x30,0x46 NUMBER KEY PAD 7 10 0x31,0x30,0x0d Number Keypad 7 110 0x31,0x31,0x30 NUMBER KEY PAD 8 11 0x31,0x31,0x0d Number Keypad 8 111 0x31,0x31,0x31 NUMBER KEY PAD 9 12 0x31,0x32,0x0d Number Keypad 9 112 0x31,0x31,0x32 NUMBER KEY PAD 0 13 0x31,0x33,0x0d Number Keypad 0 113 0x31,0x31,0x33 NUMBER KEY PAD +10 14 0x31,0x34,0x0d Number Keypad +10 114 0x31,0x31,0x34 GOTO 15 0x31,0x35,0x0d Goto 115 0x31,0x31,0x35 REPEAT ALL 16 0x31,0x36,0x0d Repeat All 116 0x31,0x31,0x36 REPEAT A-B 18 0x31,0x38,0x0d Repeat A-B 118 0x31,0x31,0x38 POWER ON/OFF 2A 0x32,0x41,0x0d Power on / off 12A 0x31,0x32,0x41 MUTE 19 0x31,0x39,0x0d Mute 119 0x31,0x31,0x39 VOLUME - 1A 0x31,0x41,0x0d Volume - 11A 0x31,0x31,0x41 VOLUME + 1B 0x31,0x42,0x0d Volume + 11B 0x31,0x31,0x42 DVD ANGLE 1C 0x31,0x43,0x0d DVD Angle 11C 0x31,0x31,0x43 DVD SUB-TITLE 1D 0x31,0x44,0x0d DVD Sub-title 11D 0x31,0x31,0x44 DVD AUDIO 1E 0x31,0x45,0x0d DVD Audio 11E 0x31,0x31,0x45 DVD MENU 1F 0x31,0x46,0x0d DVD Menu 11F 0x31,0x31,0x46 DVD ON SCREEN DISPLAY 20 0x32,0x30,0x0d DVD on screen disply 120 0x31,0x32,0x30 DVD TITLE 21 0x32,0x31,0x0d DVD Title 121 0x31,0x32,0x31 SETUP MENU 22 0x32,0x32,0x0d Setup Menu 122 0x31,0x32,0x32 NAVIGATION UP 23 0x32,0x33,0x0d Navigation up 123 0x31,0x32,0x33 NAVIGATION DOWN 24 0x32,0x34,0x0d Navigation Down 124 0x31,0x32,0x34 NAVIGATION LEFT 25 0x32,0x35,0x0d Navigation Left 125 0x31,0x32,0x35 NAVIGATION RIGHT 26 0x32,0x36,0x0d Navigation Right 126 0x31,0x32,0x36 NAVIGATION ENTER 27 0x32,0x37,0x0d Navigation Enter 127 0x31,0x32,0x37 ZOOM - 28 0x32,0x38,0x0d Zoom - 128 0x31,0x32,0x38 ZOOM + 29 0x32,0x39,0x0d Zoom + 129 0x31,0x32,0x39...
