Lucky Step 13) Once you have completed the Power Supply test, disconnect the TRACE PCB from your power supply and install the four
3.5mm I/O Jacks – DO NOT solder the jacks at this time. Note, the ground pin for the jacks is the one outside of the molded plastic part
of the jack. This is the pin that goes towards the top and bottom of the PCB.
14) Insert the Xprotolab module into the PCB. The I/O Jacks should be to your right with the Xprotolab buttons to the bottom.
15) Great, so all of the inside parts of the TRACE module are inside. The next step is to mount the front panel and then install the jack
nuts. Once you have front panel held in place with the jack nuts, insert one of the screws through front panel, through the spacer, then
through the PCB. Thread the locknut onto the portion of the screw sticking through the PCB. Repeat for the other screw. Tighten the nuts
until they are snug - no need to go crazy tight on them. If you are using pliers instead of a Knurled Nut Tool, be careful not to scratch the
front panel. Don't worry about alignment of the Xprotolab module yet, we will work on that next. Also, be sure that the I/O Jacks are
sitting flat against the PCB and the front panel.
