Using an RS-232-to-IR Adapter Connection
If the TV does not have an RS-232 port, which is typically the case for consumer
grade TVs, the JAFA SCIRTx RS-232-to-IR adapter can be used as a workaround.
This approach is discouraged due to its fragility, and lack of ability to retrieve TV
status. It should be used only as last resort.

Adapter connections for the DMP 4310G.
One disadvantage of using an RS-232-to-IR adapter (besides added complexity) is
that you must use an adhesive to affix the IR sensor to the TV. There is a good
chance that the adhesive, if exposed to weather or due to age, will pull away from
the TV’s IR sensor. This results in loss of TV control and possibly the use of ladders
and personnel to re-adhere the sensor to the TV.

IR for TV Control
IR Remote Sensor and IR Extender
If the DMP is mounted behind the TV such that the IR sensor is not visible for to IR
remote control, then the included IR extender may be used to extend IR control. The
handheld IR remote is a critical troubleshooting tool so it is important to ensure that
all DMPs can be IR-controlled even if this is not needed during normal operation.
