Up to four transmit or receive modules can be mounted in an RM4 chassis, a compact 1RU enclosure that includes dual redundant power supplies and front panel control. Two channel DVI modules are also available, allowing an RM4 to support 8 channels in a single chassis. This provides the most space efficient DVI endpoint package available. The RM4 chassis simplifies set-up with an easy to navigate cursor-operated front panel LCD display. The display provides a computer-free method of configuring EDID and checking diagnostic data. A choice of EDID modes includes selection from a factory default table, capture from a display device and real-time passthrough. Like all Opto signal path components, a 6.22Gps per channel bandwidth ensures a perfectly clean video image without artifacts caused by bandwidth limitations, particularly for timings above 1920x1080/60p . Any compliant DVI or HDMI 1.3 timing is supported and all DVI single-link modules are HDCP compliant. Contact closure relays with a terminal block connector are provided for power failure or over-temperature alarms. A BNC connector for stereo emitter sync used in 3D applications is also included. Opto RM4 rackmount modules work with other Opto products in a variety of ways: • Point-point connection between Opto rack mount transmit and receive modules • Point-point connection between Opto rack mount modules and Opto standalone transmit or receive endpoints • RM-4 modules connected to the inputs or outputs of an Opto matrix switcher
