2.20 Watchdog timer configuration

An onboard watchdog timer reduces the chance of disruptions which

EMP (electro-magnetic pulse) interference can cause. This is an invalu-

able protective device for standalone or unmanned applications. Setup

involves one jumper and running the control software (refer to Appendix

A).

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 J13 as shown below:

The POS-761F board provides four USB (Universal Serial Bus) inter-

faces which support plug and play and hot attach/detach for up to 127

external devices. The USB interfaces comply with USB specification

Rev. 2.0 and are fuse protected.

The USB interfaces are accessed through 10-pin (5x2) flat-cable connec-

tors, CN16/CN27. You will need an adapter cable if you use a standard

USB connector. The adapter cable has a 5-pin connector on one end and a

USB connector on the other.

The USB interfaces can be disabled in the system BIOS setup.
