AT-OME-MS42-HDBT
The AT-OME-MS42-HDBT provides an RS-232 port which can be used to control a display
connected to the HDMI output. Atlona recommends controlling the AT-OME-MS42-HDBT using
IP and reserving the RS-232 port for local display control.
1 Use wire strippers to remove a portion of the cable jacket.
2 Remove at least 3/16” (5 mm) of insulation from each of the wires.
3 Insert the wires into correct terminal using the included 3-pin captive screw connector.
4 Attach the 3-pin connector block to the RS-232 port on the AT-OME-MS42-HDBT.
The AT-OME-MS42-HDBT provides two-channel LPCM audio de-embedding of the source
device, using a dedicated AUDIO port. Use the included 5-pin captive-screw terminal block.
Balanced audio connections use two signal wires and a ground to minimize interference in audio
signals.
