Extron Electronics has introduced the CTR 8, a control module that adds contact closure control to most RS-232 controllable Extron simple or scaling switchers. The CTR 8 accepts up to eight contact closure inputs and converts them to Simple Instruction Set (SIS) serial commands that select the corresponding input on an Extron switcher. Video can be muted and unmuted by pressing a single switch in sequence, allowing the user to control the viewing of the presentation. Each contact closure input features a +5 VDC output that can be used to light an LED to indicate the active switch. The CTR 8 features a RS-232 serial port, a +12 VDC power loopout port, selectable video mute LED options, and a compact form factor. The RS-232 serial port allows monitoring and troubleshooting from a remote location. To streamline installation, a +12 VDC power loop-out port allows sharing of external power with another Extron product. The CTR 8 is housed in a 1RU, quarter-rack-width metal enclosure. It ships with the Extron MBU 123 low-profile mount kit.
