5.0 System Overview
The VTune is an RS232, contact closure, and IR controllable 181 Channel TV Tuner and FM Tuner. The unit was designed
for easy integration into systems that need remote control of the capabilities. The powerful yet simple RS232 protocol
gives a user full 2 way feedback of channel selections. Control systems can take advantage of the RS232 to allow true
channel updating on a touch panel or web browser. Ordinary IR only tuners can not give this type of information. Kiosks
can take advantage of the contact closure port for direct access of channel, volume, and source selection. Twelve
built in presets make getting to a users favorite TV or FM channels a breeze.
Another great feature of the VTune is the ability to upgrade the firmware for additional features or fixes. Try to keep an
eye out for the latest releases on www.auroramultimedia.com to take advantage of the new version. The firmware is
easily upload to the VTune with the Flash123 utility that is free on our web site.

12.0 Troubleshooting
TV Tuner
Random noise in video image - Check antenna position or cable connection. Weak signals can
cause noise. Use of an RF Signal amplifier may help. Check the TV Source setting in the menu for
proper selection between broadcast, cable, IRC, and HRC.
White noise - Check antenna position or cable connection. Check the TV Source setting in the
menu for proper selection between broadcast, cable, IRC, and HRC.
Hum on all channels - Poor grounding will cause this problem. The cable feed should be grounded
at entry into building or house structure. Jensen Transformers model VR-1FF CATV Ground Isolator
may also do the trick if the ground problem can not be found.
Ghosting - Check antenna position. Sometimes to much gain from the cable source can cause
this type of problem. Radio Shack sells 3dB and 6dB attenuators that might help.
RS-232
No Communication - Make certain PC or control device is set to 9600 8N1.
‘ERROR’ is always received - Some terminal programs send both carriage return and line feed (0Dh,
0Ah) when the enter key is pressed. Make certain it only sends carriage return (0D hex). When writing
code try to put a 0Dh 100ms before sending a VTune command to make certain the buffer is
empty.

13.0 Upgrading Firmware
1) Download latest copy of Flash123 from www.auroramultimedia.com under the VTune product
section.
2) Download the latest version of firmware.
3) Install Flash123 on a Windows 2000 or better machine.
4) With the power cord unplugged connect the 6 pin Mini Din to 9 pin RS232 cable between the
Control port of the VTune and the Com port of the PC. If you do not have a cable the help menu of
Flash123 has the pin out.
5) Plug the power connector into the VTune and launch the Flash123 program.
6) Select the Com port, then the file, then click on start. The firmware should start uploading. This
process could take a few minutes. Do not turn off the power to the VTune or unplug the RS-232
cable when uploading firmware.
What to do if flash upgrade fails or is interrupted:
Well everyone needs a backup plan just in case.
If a flash upload is interrupted, Flash123 will not work unless
Hardware Boot is checked under the options selection.
By selecting this, you are telling the Flash123 program
it is still in firmware upgrade mode. Once checked click
on start again.
If there is difficulty in getting the VTune into boot mode
there is a hole large enough for a paper clip in the front
panel next to the menu button. With the power unplugged
insert and hold the paper clip in while plugging the power
in. The LED should not be lit and there will be no output display. Follow the above directions for
hardware boot.
If Flash123 is restarted the default for Hardware Boot is unchecked.
