The ignition control signal is to be referenced to input supply voltage as requested by NDL and is detailed in Section 2 Product Specifications. A flow diagram is shown under 6.2 power ignition control. A TVS diode is fitted between the plus and minus power inputs, there are no voltage clamping devices between these inputs and the chassis. A standard 1000VAC voltage withstand test with shorted plus minus is supported. From EN 50155:2017:-

13.4.9.3 Voltage withstand test Nominal battery voltage and/or I/O voltage Test voltage 72 V DC V DC < 125 V DC or from 50 to 90 V AC rms 1 000 V AC or 1 500 V DC DOC#NCP-R4600 GEN2-SOW Expansion The unit is equipped with four mPCIe slots, two m.2 slots from I/O board and one m.2 slot from the motherboard as detailed in Section 2. Two m.2 slots from the modem area (Section 5.1 location M.2-1 & M.2-2) provide USB 3.0 signaling and one m.2 from the motherboard provides USB3.0 and SATA signaling for a storage device. Two mPCIe slots with USB 3.0 signaling (Section 5.1 mPCIe-3 & mPCIe-4) will be configurable to support isolation of pins 22, 28 and 48 using dipswitches, this is to allow fitment of modems requiring these pins to be left open. Two mPCIe slots with USB 2.0 and PCIe x1 signaling (Section 5.1 mPCIe-5 & mPCIe-6) will follow PCIe mini card spec V1.2. The expansion slot pin outs have been designed to support mPCIe USB3.0 and M.2 USB3.0. Installation of internal m.2 storage slot will require removal of the chassis covers. To help prevent damage to the screw head, a torx fitting will be used Torx type M3, F HEAD, L5 and their locations are shown in the chassis underside view under the mechanical drawings section.

If in the future ECC is required it may be possible to specify a suitable processor, chipset and memory to implement this feature. Note: ECC CPU support list Intel Skylake CPU i3-6100TE Software The system will support Ubuntu 16.04.6 and Debian 10.0.0 operating systems. The operating system can be installed on either the m.2 2280 motherboard slot, cFast or removable 2.5 SSD device. As standard the DOC#NCP-R4600 GEN2-SOW system will be supplied without storage media. Expansion slots M.2-1, M.2-2 and mPCIe-3 to mPCIe-6 can be powered off or on using the built in PCA-9555 GPIO expander. The GPIO expander is controlled using i2c commands. By default expansion slots M.2-1, M.2-2 and mPCIe-3 to mPCIe-6 are powered on when the system power is on. User defined LEDs labelled U1 to U8 are controlled using i2c commands to the built in PCA-9555 GPIO expander. Watchdog facility can be either controlled directly using i2c commands or through the ADLINK SEMA tool.
