There are four (eight) LED switches mounted on the front panel to select among the inputs. For remote control, there is an optional RS232 serial port that uses simple ASCII commands for input selection. The included serial control makes for a very economical remote-access SDI switcher.

In addition, the DSR8x1 can be controlled by an optional RC8x1, a separate device with illuminated switches for selection between inputs. Another optional remote control for the DSR8x1 uses DTMF tones.

The DSR4x1 and DSR8x1 are housed in Burst Electronics standard aluminum and steel enclosures that can be either desktop- or rack-mounted in a 1U rail. Power is supplied by any 9-15 Vac/dc power source using a 2.1mm circular connector (5Vdc optional). The units are polarity immune – perfect for vehicular and portable applications.
