CConnect the sleeve to ground. Connecting the sleeve to a negative (-) terminal will damage the audio output circuits.

Step 4 — RS-232/RS-422

If desired, connect a control system or computer to the Remote RS-232/RS-422 port.

		Pin RS-232 Function			RS-422 Function
		1	—	Not used	—	Not used
		2	TX	Transmit	TX–	Transmit (–)
1	6	3	RX	Receive	RX–	Receive (–)
		4	—	Not used	—	Not used
5	9	5	Gnd	Ground	Gnd	Ground
		6	—	Not used	—	Not used
		7	—	Not used	RX+	Receive (+)
		8	—	Not used	TX+	Transmit (+)
		9	—	Not used	—	Not used

Step 5 — Ethernet

If desired, connect a network WAN or LAN hub, a control system, or computer to the Ethernet RJ-45 port. See chapter 2, Installation, for details.

•Network connection — Wire as a patch (straight) cable.

•Computer or control system connection — Wire the interface cable as a crossover cable.

Step 6 — Power

Plug the switcher into a grounded AC source.

Definitions

Tie — An input-to-output connection.

Set of ties — An input tied to 2 or more outputs.

Configuration — One or more ties or sets of ties.

Current configuration — The currently active configuration (also called configuration 0).

Global preset — A configuration that has been stored. One global preset can be assigned to each input button. When a global preset is retrieved from memory, it becomes the current configuration.

Front Panel Controls

Input and output buttons select inputs and outputs. Output buttons light amber to indicate video and audio ties. The buttons light green to indicate video-only ties. The buttons light red to indicate audio-only ties. Input and output buttons also select presets.

The output buttons also display the selected input’s audio level.

The input buttons also display the selected output’s volume level.

Enter button saves changes.

Preset button saves a configuration as a preset or recalls a previously-defined preset.

View button selects a view-only mode that prevents inadvertent configuration changes. On audio models, View decrements the level and volume. See Viewing and adjusting the audio level on QS-2.
