Jumper 2

N5 ————————— E5

N6 ————————— E6

Solder two wires to program switches N5 and N6. Connect the other end to a female jumper, then to E5 and E6. Double-check the placement of the leads.

Jumper 3

E3 ————————— N3

E4 ————————— N4

E3 ————————— P5

E4 ————————— P6

This is a unique jumper. Connect two wires to E3 and two wires to E4. One of the wires on E3 will connect to N3 and the other to P5. Connect two wires to E4. One of the wires on E4 will connect to N4 and the other to P6.

Jumper 4

other end to the female jumper and then connect it to H1 and H2. Polarity is not important.

This is a simple female jumper to female jumper configuration. This jumper provides power to the controller board.

Jumper 5

D1 and D2 ————————— J1

Here, we take a two-pin female header and short the two leads together. Then, connect it to a single female jumper with one wire. This allows us to both short the jumper (enable the RS232 Reset) and route the reset to the controller board at the same time.
