Laird Telemedia LTM-4100

The LTM-4100 is a Multi-format 4x1 Routing System for the most complex Multimedia signal management. It accepts 3 Video Formats: Component, Y/C & Composite, as well as 2-Channel Balanced Audio and RS422 Machine Control for selection to a single output by simply pushing a front panel switch. The LTM-4100 can be genlocked to standard video reference signals to provide vertical interval switching of synchronous signals. In absence of an external reference, the unit defaults to asynchronous switching. RS232 external control & included Windows software provides PC-based control via its serial port. A unique embedded address allows up to Ten (10) LTM-4100 to be controlled by one PC. PAL or NTSC Compatible.
