Broadcast Tools SS2.1 III Switcher/Router. Tested with 12v power adapter and it appears to work. When pressing input 2 the relays sound like they move and the LED indicator lights as well. Currently it is setup so that it does not stay on channel 2 but returns to channel 1 by default. According to the manual this is normal behavior if dip switch 6 is on.
Package only contains SS2.1 III switcher no power supply or serial cable.
