G100 Instruction Manual
Interfaces and
Indicators
This chapter covers the interfaces of the G100 Substation Gateway.
UEFI Settings
Please refer to the document Configuring UEFI Settings on G100 User Guide (SWM0122) for details.
G100 device has the following UEFI settings that will revert to default values after the internal super capacitor
has been discharged due to the device being powered off for extended time (typically more than 5 days).
These UEFI settings are applicable only while the G100 is starting.
After the applications started, these settings are over-written by the values configured in MCP Local Configuration
Utility (mcpcfg) or MCP Settings GUI (which are persistent).
• Default Serial Maintenance Port used as UEFI (boot) console when KVM is not available
(Advanced->Serial Port Console Redirection)
o Console Redirection is set to Disabled for COM1-COM3, please do not change these settings.
o Console Redirection for COM4 should be enabled/disabled and have the “Bits per second”, to
be same as in the Serial Maintenance Port in MCP Studio (See MCP Software Configuration Guide
SWM0101 > Serial Maintenance Port).
• Default Serial Ports Modes (Advanced->Super IO Configuration)
o Please ensure are enabled/disabled as required for secure hardening purposes and set to RS-
232.
Users should check again these UEFI settings when the G100 is powered on again, and adjust as necessary.
General Purpose IO (GPIO)
G100 is equipped with an internal General Purpose Input/Output (GPIO) interface.
The available GPIO signal types are as follows.
Binary Inputs (DI): 8
All DI are wetted internally from main power supply circuit using single common for all 8 channels.
Each DI channel can be triggered by N.O. potential free external contacts, with the wetted positive voltage
being switched through the external contacts.
The DI wetting voltage is protected internally by the main fuse.
