Remote connection

D	RS-232 connector — Connect a host device, such as a computer or control
	system, to the switcher via this 9-pin D connector (figure 2-5) for remote
	control of the switcher.
			Pin	RS-232	Function
			1	—	Not used
	5	1	2	TX	Transmit data (-)
			3	RX	Receive data (+)
			4	—	Not used
			5	Gnd	Signal ground
	9	6	6	—	Not used
	Female		7	—	Not used
			8	—	Not used
			9	—	Hardwired IR

Figure 2-5 — RS-232 port pin assignment

NThe 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.

See chapter 4, “Remote Operation”, for definitions of the SIS commands and 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

5AC 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.
