on a 5-pin Terminal Block
Connectors
Connect to a serial controller or RS-232 controlled device for RS-
232 signal extension via the HDBT input.
IR (Rx, Tx) left 2-pins on a
5-pin Terminal Block
Connectors
Connect to the IR connector of an HDBT input (Tx to Rx and Rx to
Tx), to extend IR signal between an HDBT receiver on an output
and an HDBT transmitter on an input.

Mains Power Connector and Fuse
Step 3: Mounting MTX3-88-SE
To rack mount the matrix, attach both
rack ears (by removing the screws from
each side of the matrix and replacing
those screws through the rack ears) or
place the matrix on a table.
•Ensure that the environment (e.g., maximum ambient
temperature & air flow) is compatible for the device.
•Avoid uneven mechanical loading.
•Appropriate consideration of equipment nameplate
ratings should be used for avoiding overloading of the
circuits.
•Reliable earthing of rack-mounted equipment should be
maintained.
