J12 | Connect to override. the ground network and connect IC ground to module ground. |
J13 | Connect 1 and 2 to power EN1 with VDD Connect 2 and 3 to pull EN1 low. |
J14 | Connect 1 and 2 to power EN2 with VDD Connect 2 and 3 to pull EN2 low. |
J15 | Connect 1 and 2 to power EN3 with VDD Connect 2 and 3 to pull EN3 low. |
J16 | Connect 1 and 2 to power EN4 with VDD Connect 2 and 3 to pull EN4 low. |
J17 | Connect 1 and 2 to pull LATCH HI to configure the device in latch (on fault) mode Connect 2 and 3 to pull LATCH LO to configure device in auto-retry on fault. |
