1) IR Outputs - SRC1 – SRC6, TV/7, RCV/8 are eight dedicated 3.5mm jacks that output IR data specifically for that source
2) RS232 Outputs - SRC1 – SRC6, TV/7 and RCV/8 are eight dedicated 3.5mm jacks that output RS232 data specifically for that source
3) Assignable 12V Outputs - Three 3.5mm jacks, output 12V DC 150mA when activated: a. 12V outputs 1 & 2 are independent of each other and are programmable to output 12V momentarily or constantly when activated. b. 12V output 3 is assignable and outputs 12V constantly when active.
4) Assignable Relays - There are three, 3-position  removable quick-connect  plugs labeled 1, 2 and 3 for connecting either NO (normally open) or NC (normally closed) contact closure devices to the HT-MSU. 
5) IR Input - A 4-position  removable quick-connect  plug for connecting an IR sensor to the HT-MSU.  This connection allows IR control of the HT-MSU  and/or IR pass-through  for connected sources
