RemoteControl,cont’d

The SW AV Series switchers can be remotely controlled via the switcher’s rear panel Remote (SW 4 and SW 6 models) or RS-232 (SW 8 or SW 12 models) connector (Figure 4-1). Remote control devices can be:

•A host device such as a computer or third-party control system

•A device such as an Extron IR 102 Universal remote control kit

•A contact closure device such as an Extron KP 6 Keypad Control

Two or three remote control methods are available:

•Extron’s Simple Instruction Set

•Extron’s Windows-based control program

•SWS 4 and SW 6 models only, contact closure

The cable used to connect the RS-232/Remote port to a computer, control system, contact closure device, or IR control kit may need to be modified by removing pins or cutting wires. If unneeded pins are connected, the switcher may hang up.

For RS-232 control and IR control, use a control cable with only pins 2, 3, and 5 connected. Otherwise, either cut the wires to the other pins in hard-shelled connectors or remove the unneeded pins from molded plugs. See chapter 4, Remote Control, for definitions of the SIS commands and details on how to install and use the control software.

For contact closure, use a control cable with pins 2 and 3 not connected. Otherwise, either cut the wires to these pins in hard-shelled connectors or remove these pins from molded plugs. See chapter 4, Remote Control, for information on how to make a remote contact closure device.

Simple Instruction Set Control

Host-to-switcher communications

SIS commands consist of one or more characters per field. No special characters are required to begin or end a command character sequence. When a command is valid, the switcher executes the command and sends a response to the host device. All responses from the switcher to the host end with a carriage return and a line feed (CR/LF = ), which signals the end of the response character string. A string is one or more characters.
