  The cable used to connect the RS-232 port to a computer or control system 
may need to be modified by removing pins or cutting wires.  If you encounter 
problems while operating under RS-232 control (the switcher may hang up), 
pins 1, 4, 6, 7, and 8 may need to be disconnected.  Either cut the wire to 
pins 1, 4, and 6 through 8 in a hard-shelled connector or remove pins 1, 4, and 
6 through 8 from a molded plug.
 
details on how to install and use the control software.
 
Using the hardwired IR input on pin 9, you can use a control system with 
IR-learning capabilities to operate the switcher just as if you were using an 
IR 501 remote control.  The control system must first “learn” the IR command 
from an IR 501, after which it sends the same commands to the MVX via pin 9.
Power connection

  AC power connector — Plug a standard IEC power cord into this connector to 
connect the switcher to a 100 VAC to 240 VAC, 50 or 60 Hz power source.
