Page 7: Ir Remote Control, Rm-18
IR Remote Control, RM-18 Fig. 3, RM-18 The RM-18 IR remote control allows you to control all of the functions available from the unit’s front panel, with the addition of a DIM setting. POWER – Toggles between Active and Standby mode. DIM - Pressing this button cycles through four levels of brightness on the front panel lights - bright, medium, dim or off. -
Page 8: Typical Hook Up
Typical Hook up Step 1 Connect the AC adapter to 120 VAC and plug the DC cord into the 15 VDC input on the rear of the VS- 712EX. Step 2 You will determine how you want to use your system. We have provided two sample hook-up diagrams to help you determine how to connect the components of your system. - Page 9 Fig. 5 - Basic Hook-up #1 Figure 5 below shows a hook-up with only two input sources. This diagram shows only inputs 1 and 2 being used. Be sure you use either S-Video or composite video inputs, but not both on the same input. The one VS-712EX output goes to the TV so you can watch and listen on your TV.
- Page 10 Fig. 6 - Basic Hook-up #2 Figure 6 below shows a system with 3 input sources. It shows how you can watch video on your TV, listen on your surround sound receiver and record from the sources plugged into the VS-712EX. It also illustrates using the dual outputs to record on a VCR, watch the video on the TV and listen to the sound on a surround system.

Page 11: Operation
Operation When AC power is first applied, all outputs will be muted and all the lights will come on for 1 second and then go out. The Power / Stand-by light will be lit dim red. The Auto Input and Volume Stabilization modes will be active as default. -
Page 12: Volume Stabilizer Active
Note: If an input goes off and back on in less than 5 seconds, the VS-712EX may not sense the input change so no input change may occur. Volume Stabilizer Active (only on analog audio – no effect on digital audio) If the Volume Stabilizer Active light is on, then the output of the audio switcher will be routed through the Volume Stabilizer circuitry. -
Page 13: How It Works
How it works This section has more technical information for the person who wants to learn more about the VS- 712EX. In the block diagram below you can see how the audio and video inputs are selected and fed to the output buffer amplifiers. -
Page 14: Automatic Input Sensing
Automatic Input Sensing When the AUTO SELECT mode is on, the VS-712EX constantly scans the video inputs, Composite, S- Video, and Component waiting for a video input. When you turn on a device (VCR, DSS, etc.) a microprocessor in the VS-712EX senses the video input, turns on the VS-712EX (when it is in the stand- by mode) and selects the input. -
Page 15: Composite To S-Video To Component Conversion
Composite to S-Video to Component Conversion The VS-712EX has special circuitry to convert the composite video inputs to the S-Video outputs and the composite/s-video signals to component video. The VS-712EX sends the original composite and the generated s-video signal to both sets of outputs and it takes the s-video signal and generates a component video signal. -
Page 16: Digital Audio Conversion
Digital Audio Conversion The VS-712EX converts the coaxial and optical digital audio inputs and sends the signal out both the coaxial and optical outputs simultaneously. This lets you connect a single digital audio cable (either optical or coaxial) between the VS-712EX and your receiver and feed the VS-712EX with both coaxial and optical inputs. -

SVS-CONTROL Interface The SVS-CONTROL interface on the VS-712EX lets you connect the unit to a home automation system and control the various functions of the unit. SVS-CONTROL Connection The specifications of the SVS-CONTROL port are: 9600 baud 1 start, 8 bits, no parity no handshaking DB-15, female connector Here is the pin out of the SVS-CONTROL port on the VS-712EX... -
Page 19: View Video Commands
Message Acknowledgement The VS-712EX will ignore any message that does not begin with the @ character. When the VS-712EX receives an correctly initiated RS232 message, it will respond with an acknowledgement message, followed by a block of data, as appropriate. The acknowledgement message consists of 3 bytes (a start character, an address character and a status character), The message structure is summarize in the following table: Start Address... - Page 20 Page 20...
- Page 21 RS232 Status Response The returned data format (in response to a status request) takes the following format: Message header = $*2 as per section 7.3 above (* = RS232 address). Message data = VE?RE?CS?CL?SD?SL?SS?SA?SR?SP? (where ? represents a numeric value). Note that the mnemonics are the same as for the received RS232 commands.
