Parity bit: none
Flow control: none
• 4 RJ-45 (1) connector - This is the LAN port connector with DHCP server function.
• 5 RJ-45 (2) connector - This is the WAN port connector.
• 6 WLAN PHY - This is the wireless LAN physical layer circuitry.
• 7 WLAN antenna - This is he antenna for wireless LAN.
• 8 WPS push button - This button is used for WPS function.
• 9 USB connector - The two connectors are USB hosts with support for mass storage
devices.
Currently, there is no auto detection for plugged in devices; the devices will need to be
manually mounted.
• 10 Z-Wave module - this is a Z-Wave static controller which can monitor/control other
Z-Wave based devices/sensors.
• 11 Z-Wave module antenna - This is the antenna for the Z-Wave module.
• 12 Push button 1 - this push button’s state is accessible via GPIO pin 4. If depressed
before system power on (or software reboot), system enters download mode. This mode is
used by SerComm during mass production, if board is accidentally booted into this mode,
power off than power back on.
• 13 Push button 2 - This push button’s state is accessible via GPIO pin 6. If depressed
before system power on (or software reboot), then release during boot up sequence, the
LAN, WAN and wireless LAN settings are restored to default value. However, GPIO pin
6 is also tied to RESET pin of the Z-Wave module. Hence, if push button 2 is depressed
during normal operation, Z-Wave functionality may behave unpredictably.
• 14 Programmable LED - These are seven single coloured and one bi-coloured LED
controllable by firmware.
Below is a close up of the console port. The pin definitions are:
Pin 1 - Vcc
Pin 2 - Receive
Pin 3 - Transmit
Pin 4 - Ground
