Using an RS-232-to-IR Adapter Connection
If the TV does not have an RS-232 port, which is typical for consumer grade TVs,
an RS-232-to-IR adapter is required. Although this approach is strongly
discouraged, you can use the JAFA SCIRTx RS-232 to IR adapter. Figure 24 and
Figure 25 illustrate the RS-232-to-IR Adapter connections for the DMP 4310G and
DMP 4305G, respectively.

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 Remote Sensor and IR Extender
If the DMP is mounted behind the TV such that the IR sensor is not visible for IR
remote control then an USBIR extender may be used to extend IR control.

The USBIR (infrared) extender (Figure 26) is a small device where an IR transmitter
at one end of the cable is connected to the DMP IR sensor. The other end of the
