Table 13. Main logic board service pin buttons and jumper
Service pin buttons/jumper | Function |
|
|
S1 | This service pin is the reset button. Pressing S1 reboots the controller. It starts the |
| same operation as does rebooting the controller from either the controller or the PC |
| software. All RAM data is permanently lost. |
| Note: Before pressing this button, attempt to restart the controller by cycling power; this method |
| retains the RAM image. |
|
|
S2 | Momentarily pressing this service pin button causes the controller to broadcast |
| Neuron ID and Program ID. This action also turns on LED9. |
|
|
J1 | This jumper is for factory use only. It must always remain in place. If removed, the |
| backup capacitor will not charge and data may be lost if power is lost. |
