The default protocol is 9600 baud, 1 stop bit, no parity, and no flow control. The rear panel RS-232 9-pin D connector has the following pin assignments:

	Pin	RS-232 function	Description
	1	–	No connection
	2	Tx	Transmit data	5	1
	3	Rx	Receive data
	4	Tx 2	Transmit data
	5	Gnd	Signal ground	9	6
	6	–	No connection	9	6
	6	–	No connection	DB9 Pin Locations
	7	–	No connection	DB9 Pin Locations
	7	–	No connection	Female
	8	Rx 2	Receive data	Female
	8	Rx 2	Receive data
	9	–	No connection

Pins 4 and 8 (Tx2 and Rx2) are used to communicate with a slaved switcher (if one is connected). A slave adapter cable (Extron part #26-386-01) is required for slaving. For details, see “Connecting and Slaving A Switcher” in this chapter, and also see “Switcher Setup/Configuration” in chapter three.

Connecting and Slaving a Switcher

One switcher can be connected (slaved) to the System 7SC to allow for a greater number of inputs. The System 7SC serves as the master switcher, communicating with and providing video output to the projector/display. The switcher (“slave”) that is connected to the System 7 provides up to ten (10) additional input connections. See the illustration on the next page for a list of Extron switchers that can be used as slaves.

A System 7SC cannot be used as a slaved switcher.

The RS-232 and video cable connections must be made between the slaved switcher and the System 7 before the System 7 can be configured (via front panel or RS-232) for slaving.

Do not attach any communications or control devices to the slaved switcher except a contact closure remote control, if one is needed.

To connect a slave switcher to the System 7SC, do the following:

1.Connect the slave switcher’s video and audio outputs to input 1 of the System 7SC. See “Rear panel inputs”, page 2-5, in this manual, and refer to the slave switcher’s user’s manual for details on cabling.
