The maximum load of the feeback connector is 50 mA. If you want to connect something with a higher current load, connect an external power supply - then the maximum load is 1A.

New Puzzle Controller Instruction & General Information[edit | edit source]

Transforming a twisted-pair cable to a simple sensor[edit | edit source]
  • Target: Make a simple sensor
  • Difficulty: Easy

If you would like to send a win state on the port of Universal Puzzle Controller you simply need to connect DB (green) and GND (white & blue or brown) wires.

If you want to use crossover cable or you are not sure what kind of cable has been used, you need to connect CA (white & orange) wire with +12V (blue or white & brown) and CB (white & green) wire with GND (white & blue or brown). By doing that, you allow UPC to detect the type of cable used.

Digital DA and DB lines[edit | edit source]

DA and DB are TTL Lines. Universal Puzzle Controller controls DA line and reads DB's state.

One of the ports of the Universal will be active if the user will pass the low state to the DB line of this port.

If the user will read low on DA line, the UPC will go to the win state.

Communication CA and CB lines[edit | edit source]

These lines are mostly used to detect the type of twisted pair cable used (simple / crossover).

If APD was connected, data will be sent using these lines between UPC and APD (bidirectionally and asynchronously) just after the handshake procedure.

Technical info[edit | edit source]

Twisted pair cable wiring (RJ45) in Universal Puzzle Controller (UPC)[edit | edit source]
Name Function Description
1 (White & Orange) CA Communication Differential data transfer
2 (Orange) DA UPC4 digital output LED relay
3 (White & Green) CB Communication Differential data transfer
4 (Blue) +12V Power +12V power
5 (White & Blue) GND Ground Ground
6 (Green) DB UPC4 digital input Button, RFID sensor, reed switch
7 (White & Brown) +12V Power +12V power
8 (Brown) GND Ground Ground

Step 1[edit | edit source]

Take a twisted-pair cable and cut it in half.

Step 2[edit | edit source]

Take one half of previously cut cable and using an insulation stripper and remove around 2-3 cm (0.8-1.2 inch) of cable cover.

Step 3[edit | edit source]

We would like to have access to CA (White & Orange), CB (White & Green), DB (Green), +12V (Blue) and GND (Brown) wires. To do so we need to remove their covers using an insulation stripper or wallpaper knife.

Step 4[edit | edit source]

Next, we need to make sure that the Universal Puzzle Controller will be able to detect what kind of cable was connected. To do so we connect CA (White & Orange) wire with +12V (Blue or White & Brown) and CB (White & Green) wire with GND (White & Blue or Brown). I would recommend soldering them together to make sure they won't disconnect.

Step 5[edit | edit source]

To make UPC go into win state we need to connect DB (Green) wire with GND (White & Blue or Brown). I highly recommend using cable collets to make connecting them easier.

Watch out![edit | edit source]

I highly recommend using insulating tape to cover every wire except for DB and previously used GND, because making a connection between (+12V) and ground (GND) will cause a short circuit and will blow the fuse on a UPC!

Old Puzzle Controller Instruction[edit | edit source]

Make your own input old controllers

Make one puzzle controller input of the other puzzle controller[edit | edit source]

Step 1[edit | edit source]

You will need:

– 2x Universal Puzzle Controller,

– 1x Relay module,

– 1x Green-screw terminal (included with each Universal and each Output relay module),

– 2x Ethernet cable,

– 1x Make-Your-Own sensor (MYOS module),

– one two-wire cable or two wires.

Step 2[edit | edit source]

Put the GND input in the Make-Your-Own sensor with the middle slot in the green-screw terminal.

Step 3[edit | edit source]

Put the SIG input in the Make-Your-Own sensor into the left slot in the green screw terminal.

Step 4[edit | edit source]

Connect the green-screw terminal to the Relay module. The connections:

– Relay NO -> Make-Your-Own sensor's SIG

– Relay COM -> Make-Your-Own sensor's GND

Step 5[edit | edit source]

Everythings done! Now connect the Universal puzzle controller (as the sensor) to the Output relay module via an Ethernet cable. The Universal puzzle controller (as the main puzzle) needs to be connected to the Make-Your-Own sensor – also via an Ethernet cable.
