3.3 Serial port (RS232C)/Boot-up
The back panel serial port is live from BIOS startup to full operating system bootup. The default serial port
parameters are 115200 8N1, with no flow control. Pin-out of the port is listed in Table 4. A null-modem
cable must be used to connect to another computer. Press F10 during bootup to enter boot devices
selection, select Payload[setup] to select BIOS options.
This serial port access is useful during development phase and porting of operating system. During regular
production use, network ports (WAN/LAN1/LAN2/Wi-Fi) can be used for access and control of NES.

4. Internals.
Open the metal enclosure of NES to access the mini-PCIexpress slots, SD card slot, SATA and the dual sim-
card. It is recommended that NES is powered-down during this operation. The main CPU is on the bottom
side of the PCB. The bottom section of the enclosure is thermally connected to the processor and functions
as heat-sink. Four screws are used to secure the motherboard to the bottom section of the enclosure. A
thermal compound is used at the interface between the heatsink and processor.
Major connectors of NES motherboard are listed in Figure 3. Use Figure 4 to identify the pin 1 location of
specific connectors that are listed below.
