Introduction
The MedeaWiz 8X78 is an Input expander for the Sprite video player. It also has provisions to
add 8 sinking outputs, or 6 additional 3.5mm ports to control up to 6 more Sprites.
The base model is equipped with screw terminals and programmed to take up to 8 inputs and
control up to 8 trigger files on the Sprite. You can use pushbuttons, other dry contacts, or logic-
level voltage change with Low transition trigger.
You can choose to allow an interrupt from a new trigger event, or not to allow an interrupt, by
a jumper switch.
In the Serial Control Mode you can have a looping video and control other videos to play on
command. Once the commanded video ends, the looping video will play again until a new
command is received.
The 8X78 is powered by the Sprite over the included 3.5mm 4 pole plug-in cable.

8X78 Quick Start Guide
Connect pushbutton / trigger inputs and name your files as follows:
Trigger / Button -- Use terminals -----File Name
1 1&C 001
2 2&C 002
3 3&C 003
4 4&C 004
5 5&C 005
6 6&C 006
7 7&C 007
8 8&C 008
Switch Jumper S1 installed = no interrupt. Removed = interrupt on new trigger.
Connect the Sprite I/O port to the 8X78 Serial Port using a 3.5mm 4 pole cable.
Set the Sprite Control Mode to Serial Control, and set the Baud Rate to 9600.
Name your files to match the input numbers. You must also have a 000 looping file.

8X78 Options
Circuit Board Options
The circuit board has provisions to add:
1) A ULN2803 driver IC and a 10 position screw - terminal strip. This will allow driving low voltage lamps
or relays. We can install this on request, or you can install it. The standard included programming will
drive each of the 1 to 8 outputs while the corresponding file 001 to 008 is playing.
OR
2) Up to 6 more 3.5mm 4 pole jacks to interface up to 6 more Sprites. This option will require custom
programming. Depending on your needs, there are multiple possibilities.
There is provision, by cutting trace and bridging solder gap, to allow up to 25 pushbuttons / dry contacts
inputs in a 5 x 5 matrix. This will require a programming change in the 8X78.
The Stack Port allows stacking of a Sprite circuit board with the 8X78 for custom OEM applications. It
shares the connections with the 3.5mm 4 pole Serial Port.
The Program Port allows direct programming of the PIC processor using widely-available third-party
tools such as the PICKit™ 3. Free software development tools are available from
http://www.microchip.com/
Programming Options
The 8X78 comes pre-programmed to take up to 8 triggers / pushbuttons that will play up to 8 files, and
will drive the optional ULN2803 output driver, if installed.
You can re-program the PIC processor to meet custom needs, or contact us for a quote on a custom
program.
