One DB9 RS232 interface (9600 bits/sec, 8N1) Power input socket (barrel type, centre positive)

Indicators: Per-input LED indicates valid (solid)/invalid (flashing) HDMI input selected

Controls: Front-panel button manually steps through inputs; RS232 input selection; control via Meridian DVD-A/V player; infrared control with G12 sensor (not sup- plied)

Power: Unit accepts DC in the range 6–15V, <3VA (W)

The 421 Switch can be controlled in several ways. For direct use, a front-panel button al- lows the users to step through the inputs. LEDs indicate which input is selected.

For serial control, a 9600 baud serial port is pro- vided, allowing interfacing via RS232 command. In addition, sources may be assigned to different inputs, eg DVD = input 1, etc.

This allows the unit to be controlled via Meridian Comms (DIN or BNC) so as to select the correct input automatically when a source is selected in a Meridian system.

Input assignment can also be carried out in the Meridian configuration application.

Input 1 on the 421 Switcher also automatically senses the presence of a Meridian DVD-Audio/ Video player. When the Meridian player detects the presence of a Switcher, a range of ad- ditional options become available in the player’s on-screen display allowing video sources to be assigned to the other Switcher inputs instead of going via the player’s internal format conversion and scaling. (Player firmware revision 1.86 or later required.)

A G12 infrared sensor may be connected via a Comms port for infrared remote control capabilities.

The 421 Switch includes indicators correspond- ing to each input to show which is currently

selected. The selected input indicator comes on solidly when an HDMI input is valid, and flashes when it is invalid.

The 421 Switch is powered by a separate univer- sal voltage supply or may be powered by any DC supply from 6 to 15V, at under 3W. It has rubber feet that may be removed to reveal mounting holes for permanent installation.

Both the 121 Extender and 421 Switch pass both HDMI audio and video and are completely transparent to handshaking, control and data signals, with extremely high bandwidth and virtually zero latency.
