Enable Serial Console on B series TV

Attention: Do everything at your own risk. You warranty may be void! I take no responsibility for any damage that may be caused on your device. Tested on a UE46B7000 only

1) Solder yourself ( or buy ) an Ex-Link serial cable to connect to your Samsung TV. See here for the Serial Cable specs. You can ignore the rest of the information posted there, as it is not applicable for the more recent Samsung devices.

2) Enter Service Menu ( quickly push [INFO] [MENU] [MUTE] [POWER] on your remote control )

3) Change setting for your RS232C interface to "debug" ( Control -> Sub Option -> RS-232 Jack -> [ Debug | UART | Logic ] )

4) Use following connection parameters with your terminal-client ( e.g. Hyper Therminal or ZOC Terminal ): 115200,8,n,1,n

5) Switch on your TV ... you should see the boot-log on your terminal, if you did everything right!

5) Enter "debug" at the invisible prompt ... to enable your serial console. You should see something like below with each keystroke

[SERIAL INPUT MANAGE] 1-th ENABLE Magic serial input match! [SERIAL INPUT MANAGE] 2-th ENABLE Magic serial input match! [SERIAL INPUT MANAGE] 3-th ENABLE Magic serial input match! [SERIAL INPUT MANAGE] 4-th ENABLE Magic serial input match! [SERIAL INPUT MANAGE] 5-th ENABLE Magic serial input match! [SERIAL INPUT MANAGE] serial input ENABLE!!!!!

6) Now you need to be fast ... a) hit CTRL-C, which stops the exeDSP binary b) immediately after that enter ( you have ca. 3 seconds ... I suggest you cut&paste this command )

/mtd_boot/MicomCtrl 23

This now prevents your LED/LCD to stop and you have a command prompt of the TV-Console.
