Troubleshooting
Display: Routed an audio input to an output, but the display didn’t show the new
route.
√ – The display on the front panel only reflects the video route, the audio route is
not represented.
Display: The front panel display is off.
√ – Verify power is applied. If power is applied, have a service technician check
fuse at power connector.
Audio: There is no volume for a selected output.
√ – Make sure volume level is not set to 0 from the front panel.
√ – Make sure the route is to the correct output.
√ – Verify audio source as input.
√ – If using RS-232 port, make sure the output was not muted.
Audio: Volume is higher on certain outputs.
√ – Check output volume level from front panel, typical setting is 32 (0 dB).
√ – If using RS-232 port, check input sensitivity settings.
√ – Check cables.
Video: No video on output.
√ – Verify the route is to the correct output.
√ – Verify video source as input.
√ – Check cables.
Digital Audio: Routed an audio input to an output, but the digital didn’t follow the
route.
√ – If using RS-232 port, make sure the digital has not been detached from the
audio, refer to the Digital Commands section of the manual.
√ – Make sure a composite source being used on a digital input is not being routed
to that digital output.
√ – Check cables.
RS-232: SVS-88 is not responding to serial messages, not even with MX00-
PARDON!
√ – Verify that a carriage return (ASCII 0D) is the last character in the message
sent.
√ – Verify that the SVS-88 baud rate is the same as that in the system controller or
terminal software. In addition to the correct baud rate, the data must be sent with 8
data bits, 1 stop bit and no parity.
√ – All messages are case sensitive, make sure commands are sent in upper case.
Presets: Preset programmed via RS-232 will not execute completely.
√ – Make sure preset sub-numbers are used sequentially, any gap between
numbers will terminate the preset at that point during execution.
