DIP switch #
The DIP switch for configuration on the front of the edge gateway sets the startup mode of the edge gateway.
Explanation of DIP switch icons #
| DIP switch | Description. |
 | ON state |
 | OFF state |
The No. 4 DIP switch can be ON or OFF. It is not referenced by the boot loader (used only on the application side).

PUSH switch #
Holding down the PUSH switch for 3 seconds after booting the OS places the edge gateway in a power-off state.
If the power-off state continues for a certain period of time, the edge gateway is restarted by Watchdog Timer. This makes it possible to recover from a command operation (e.g., poweroff command) without going to the site, even if the command operation (e.g., poweroff command) was remotely powered off by mistake.
When the DIP switch is set to “U-Boot command mode,” various settings are initialized to the factory defaults by turning on the edge gateway with the PUSH switch pressed and holding the PUSH switch pressed for at least 3 seconds.
Note that setting files stored in the device will not be initialized. Therefore, if the device is rebooted after this operation is performed without writing to the settings file, it will start up with the settings before the settings are initialized.
CONSOLE Port #
Indoor Type Edge Gateway #
The indoor type Edge Gateway Console is CISCO Console compatible at the RS-232 level, so CISCO console cables can be used.
Refer to the table below for the signal pin numbers assigned to the RJ-45 and the connection to the edge gateway.

D IN / D OUT port #
This section describes the digital input (D IN) and digital output (D OUT).
interface circuit #
The edge gateway has a digital input (D IN) and a digital output (D OUT) interface. One connector can be connected to each port.
D IN / D OUT Port Overview
| port | Description. |
| Digital input (D IN) | When the photo coupler of D IN is turned ON, a minimum current of 1.2mA is required. ● As a protection element, a 30V zener diode is mounted for isolation from the internal circuit. ● The photo coupler of D IN uses a bi-directional light emitting type LED. |
| Digital output (D OUT) | ● Uses a photomos relay ● Maximum current drive capability is 100mA ● Maximum on-resistance is 2Ω ● As a protection element, a 30V zener diode is mounted for isolation from the internal circuit Surge protection is required for items that generate a surge when turned on or off. |
Below is a schematic of the internal interfaces associated with the digital inputs and outputs.
