Scorpion can send or receive commands and values to or from other applications over RS232. Thus Scorpion can be configured and managed from external systems. These can also be other Scorpion systems. An external system may also send commands, set values in or receive values from Scorpion.

The dialogue to set the connection for the RS232 protocol is shown below. The window will continuously show the commands and values transmitted between Scorpion and the external system.

  • Active - The RS-232 TDVCmdProtocol interface is activated checking the Active options - default off
  • Send command response - Is default off. It is normally check when setting up or debugging the system to verify that the Scorpion system is alive.
