In case of starting from blanked flash, it’s necessary to write “ tcl.img” file via factory copy in advance.

OAD Stream
(This function is not ready by SW)
To manage quicker mass reflashing on predefined DVB Channel, some licensed IBL tools ('xxx2lli.exe', 'lli2dsm.exe',
dsmmerge.exe …) from Intel byte Inc. might be necessary to create appropriate DVB SSU image. Over some predefine
settings such as repeated data block insertion, null packets size, … that are controllable in configuration file, here below
are mandatory OUI entries structure to prepare DSM-CC carousel image format:
- export CUST_OAD_OUI 0x001C50
- export CUST_OAD_HW_MODEL 0x5395
- export CUST_OAD_HW_VERSION 0x0000
- export CUST_OAD_SW_MODEL 0x0001
- export CUST_OAD_SW_VERSION
0x00

OAD reflashing is managed within 4 steps operation: multiplex detection, DVB transfer, flashing and warm-start.

UART & IR Parser
To use both UART and/or IR parser, TV has to be set in Factory mode with its USB port well connected to suitable
UART device or an IR emitter device correctly facing up TV (see below “section 2.0 - Product Assembly” how to
activate “Factory key”).
The UART parser engine is enabled by sending following command “
0xE2
” from host to TV within following presets
115200 / 8 / n / 1 .
Once initialized, “ PS ” caption is toggle displayed on bottom left screen (“S” like Serial).
To communicate with TV depending on SIACP revision layout implementation, you need to fulfill UART/IR
commands protocol and format described on enclosed SIACP requirements document (rev. v8.31).
1.4.Project ID Modification
There are different IDs stored into the eMMC depending on different Panels settings and Models features, but
there’s only one key branching ProjectID that includes all. So it’s not recommended to modify Panel ID with Hyper
terminal as other ID features may not change!
To modify ProjectID, first of all you need to enable Factory Hotkey (See below “section 2.0-Product Assembly”). After
that, go through1950 to “
Main menu

Service menu

8-Project ID ”, then turn left or right with RCU “◄ / ►” key”
keys to suitable ID (Project name is dynamically refreshed). Restart TV.
