B-Lan Setup & Overview - LG Pro Centric 37LT777H Commercial Mode Setup Manual

The b-LAN module is internal to the TV. It allows hotel/institution head end equipment with b-LAN technology
to communicate, via the institution's RF distribution system, with the TV for configuration and control.
Installer Menu item 118 POWER SAVINGS controls the power circuitry for both the embedded b-LAN module
and the GAME CONTROL/MPI port (see note below). The default value is 3—the b-LAN module is only pow-
ered when the TV is turned ON. See chart below.
SAVINGS
3 (default)
A b-LAN enabled head end device, such as an LG FMA-LG101, broadcasts over the RF distribution system
to communicate to multiple TVs. When the TV is first installed, it must be turned ON in order for its embedded
b-LAN module to receive communication from the head end device. At this point, if it is desired for the b-LAN
module to always be powered, including while the TV is turned OFF, set Installer Menu item 118 POWER
SAVINGS to 1.
Also, if MPI communication is required for external MPI control, set Installer Menu item 118 POWER SAVINGS
to 1 so that the GAME CONTROL/MPI port circuitry is always powered.
For specific applications, the RS-232 (DB9) port may be used to provide +12v/1A external power (for
example, to an external MPI control device). In this case, Installer Menu item 118 POWER SAVINGS must
be set to 9—both the b-LAN module and the GAME CONTROL/MPI port circuitry are always powered,
and the external power is provided on pin 9 of the RS-232 port.
Caution: POWER SAVINGS should NEVER be set to 7. This setting is intended for factory use
only.
