Re: how to build a VEX programming module
You can use an in-circuit debugger to program both the master and user processors. You have to open the case to access the connector.

Using the pin designators on the silkscreen of the pc board, here is the pinout:

J1-17 PGD on the Master Processor
J1-18 MCLR on the Master Processor
J1-19 +5v
J1-20 no connect
J1-21 Port B7 and PGD on the User Processor
J1-22 MCLR on the User Processor
J1-23 RX2 on the Master Processor
J1-24 GND
J2-9 PGC on the Master Processor
J2-10 GND
J2-11 Port B6 and PGC on the User processor
J2-12 TX2 on the Master Processor
