To begin using the programmer (Desktop unit), simply plug the 6-pin DIN cable into the PG-800 Mini and the synth. If you have a PG-800 Mini installed in your JX, the programmer starts up as soon as the synth is powered on.
1 second will disable transmissions from the PG-800. This is useful if using the JX in a performance. Once in disable mode, tapping manual will return the PG-800 Mini to its normal state. Any controls that were moved while transmission was disabled will be updated upon enabling transmission.
PG-800 MINI PCB BUILD NOTES The PG-800 Mini is available as a DIY bare PCB kit, as well as a fully assembled “internal” unit. This section is for people building their own units and installing units into the chassis of a JX-8P or JX-10P.
These holes should be .125” in diameter. Position the template on the synth so that the PG-800 Mini PCB sits directly to the right of the JX front panel PCB as shown below. The two should not touch. When the drill template is in position, tape it down and use a center punch to mark the hole locations.

When the overlay is placed, use the screws and spacers to create 6 standoffs as shown in the figure below. These standoffs are what the PG-800 Mini will mount to. This must be done with the graphic overlay applied to the panel. Insert the black screws (through the front panel facing side) into the 6 small mounting holes in the panel.

5-pin multi-conductor wire and connect the 5 wires from the PG-800 Mini to the JX as shown in the wiring diagrams. The 5 connections on the PG- 800 are indicated on the top side of the PCB where the DIN jack terminates. These 5 connections must be connected to the Jack PCB on the Super JX, and the Main PCB on the JX-8P.
