2.1 RJ12 control port
The 6 wire RJ12 port enables the LHDMI66 to be controlled by a proprietary LEAF
controller such as the TC3.
2.2 4 way DIP switch module
The rear panel accessible 4 position DIP switch controls functionality of the LHDMI66.
The table below summarizes the settings:
NOTE: The interface will only read the DIP switch settings on power-up. The unit must
be powered off and then back on again for it to respond to any change of the DIP
switch settings.

2.3 3.5mm IR ports
The 3.5mm Remote IR connectors are used for routing external IR control signals in
one direction between the LHDMI66 and the connected LB1 breakouts. These
connections are treated as through connections. That is, IR port 1 connects to the
breakout connected to Zone 1, through to port 4 being connected to the breakout at
Zone 4.
The IR ports support direct connection and drive of Leaf “hammerhead” and other
compatible 5 volt, 3 wire (Tip Ring Sleeve / stereo plug) IR detectors to Leaf LB41 and
other compatible 2 wire (mono plug) IR blasters.
The system wide operating direction of the IR detectors and blasters (either Hub to
Zones or Zones to Hub) is configurable by DIP Switch 1.
If the IR Direction is set to “Hub to Zones” by DIP switch 1, the IR ports on the
LHDMI66 can be further configured by DIP Switch 2 to accept direct IR drive from an
external control system or similar instead of stand-alone IR detectors.
For this configuration, Stereo (Tip Ring Sleeve) 3.5mm leads must be used instead of
Mono leads for the IR interconnections from the control system to the Leaf LHDMI66.
