Automated detection of communicational system type

A communicational type detection system comprising:

• a first comparator circuit comparing one or more voltages of a communication of an communicational type, received from a remote device, to a first threshold voltage, the first threshold voltage differentiating between:
• (1) communications conforming to a first communicational type and (2) communications conforming to a second communicational type, wherein voltages indicative of binary values according to the first communicational type differ from voltages indicative of binary values according to the second communicational type;
• and
• one or more processing units to which output of the first comparator circuit is connected, the one or more processing units being configured to set a communicational type, that will be utilized by a first communicational device to communicate with the remote device, to one of the first communicational type or the second communicational type based on the output of the first comparator circuit;
• wherein the first communicational device can utilize one of multiple communicational types to communicate with the remote device, the first communicational device's communicational type settings being controllable by the one or more processing units, and
• further comprising a second comparator circuit comparing the one or more voltages of the communication of the communicational type to a second threshold voltage, the second threshold voltage differentiating between:
• (1) communications conforming to one of the first or the second communicational types and (2) communications conforming to a third communicational type, wherein voltages indicative of binary values according to the third communicational type differ from at least one of:
• the voltages indicative of the binary values according to the first communicational type or the voltages indicative of the binary values according to the second communicational type,
• the communication of the communicational type is one of an External interrupt request (EIR), Output data request (ODR), External function request (EFR) or Input data request (IDR) handshake input;
• the first threshold voltage differentiates between a binary “0” according to Naval Tactical Data System (NTDS) Type B and a binary “0” according to NTDS Type A;
• and
• the second threshold voltage differentiating between a binary “0” according to both NTDS Type B and NTDS Type A and a binary “0” according to NTDS Type C and NTDS Type H.
