2.19.2 Network boot
The Network Boot feature can be utilized by incorporating the
Boot ROM image files for the appropriate network operating
system. The Boot ROM BIOS files are included in the system
BIOS, which is on the utility CD disc.
2.20 Watchdog timer configuration
An on-board watchdog timer reduces the chance of disruptions
which EMP (electro-magnetic pulse) interference can cause. This
is an invaluable protective device for standalone or unmanned
applications. Setup involves one jumper and running the control
software (refer to Appendix A).
2.20.1 Watchdog timer action (JP2)
When the watchdog timer activates (CPU processing has come to
a halt), it can reset the system or generate an interrupt on IRQ11.
This can be set via setting JP2 as shown below:
