To implement Remote Off using a custom cable connect J2_2 (Remote Off) to J2_13
(Remote_Off_Return) through a mechanical switch, relay or transistor switch powered by the 28V supply.
Refer to Chapter 4 for more connector information.
Write Protect
For configuration control, the DuraCOR 311 provides a write protect connection to the mSATA, BIT
microcontroller, and the PCIe Ethernet MAC/PHY. Asserting this signal causes the mSATA and PCIe
MAC/PHY devices to be unwritable. The write protect connection to the BIT microcontroller is for
monitoring purposes. The write protect input is accessed from J2_30 and J2_37, see Chapter 4.
Power Hold Up
The DuraCOR 311 has the option of 50 ms hold up at 40W. Hold up may be incorporated into the system
without any size increase to the system. Hold up is not a standard feature; please contact your sales
representative for system part numbers containing hold up.
