- | Jumper JP1 should be left unfitted. JP3 should be fitted and jumper-ed to short pins 1 and 2. JP4 should be fitted and pins 1 and 2 shorted. Note that our newer PCBs don't need any jumpers. | + | Jumper JP1 should be left unfitted. JP3 should be fitted and jumper-ed to short pins 1 and 2. JP4 should be fitted and pins 1 and 2 shorted.

If you have relays to fit, it is easier to fit the diode, resistor (4K7 ohm) and transistor (required to drive the relay) before fitting the relay itself. <note warning> | If you have relays to fit, it is easier to fit the diode, resistor (4K7 ohm) and transistor (required to drive the relay) before fitting the relay itself. <note warning> | ||
