OPERATING MODES

SPECIFICATIONS

Here is the complete specification.

Please use the Control App from INOGENI to identify the hardware revision of your product.

SERIAL COMMUNICATION PROTOCOL

Here is the complete list of commands provided through the serial connection: Pinout is indicated on the enclosure.

Baud rate: 9600 // Data bits: 8 // Stop bits: 1 // Parity: None // Flow control: None

All commands will append to the return values 2 possible answers: “ACK” or “NACK” with “/n/r” chars.

GPIN MODE

With the introduction of firmware 1.1+, there are two (2x) GPIN modes: pulse mode and level mode.

• – The GPIN pulse mode is the factory default. Each transition from HIGH to LOW on GPIN pin will force a PC change. See the following picture for the explanation of the mode.
• The GPIN level mode uses a level “0” (short to ground) and “1” (open or voltage higher than threshold) to select a specific PC.
  • A level “0” or short to ground: PC2 is selected.
  • A level “1” or open: PC1 is selected.

IMPORTANT NOTES ABOUT GPIN

• It is recommended to set the Toggle in manual mode with the UART command “sm” when using the GPIN (especially with level mode). If the Toggle is used in auto mode, any changes on the PCx side will affect the PC selected even if the GPIN level mode is used.
• It is also recommended to lock the button with the UART command “slck” when the GPIN is used in level mode.
• For Toggle with a hardware revision of 2.0, you need to connect the external power supply to use the GPIN. The Control App software from INOGENI will report the exact hardware revision.

SETTINGS

Some settings can be saved with the “SAVE” command. These settings are:

• Presence or absence of events on serial ports. Events are used for diagnostic. An event returned by the unit always starts with the string “EVT:” The “SEV” serial command is used to enable/disable the events. This command also automatically saves this setting inside the device.
• Manual or automatic mode for PC selection. The “SM” command is used to switch between manual and automatic modes. This command also automatically saves this setting inside the device.
• If manual mode is selected and the GPIN level mode is disabled: the specific PC selected is also saved. The “SH” command is used to select between PC1, PC2 or OFF. This command also automatically saves this setting inside the device.
• If the button is locked or not. The “SLCK” command is used to select between these modes. This command also automatically saves this setting inside the device.
• If the GPIN level mode is selected or not. The command “SGMOD” is used to select between these modes. This command also automatically saves this setting inside the device.
• The “DEF” command restores the default settings of the device. It will take effect immediately. The factory default settings are:

1. No events.
2. Automatic mode for PCx selection.
3. GPIN_LEVEL disabled.
4. Button unlocked.
