PC Interface ProtocolIn a Multi RF Deck/ Multi Control Head structure, the remote control by applications such as KAS-10 is available by usinga serial interface port of the transceiver.If a PC command is executed from COM 1 or COM 2 of a D-sub 25-pin connector of an RF Deck, the communication portsof each RF Deck behave individually according to the configuration for the connected RF Deck, regardless of whether theRF Deck is the Selected RF Deck or Unselected RF Deck.If a PC command is executed from COM 0 in a Multi RF Deck system, the communication port (COM 0) of the Selected RFDeck behaves. If a PC command is executed from COM 0, a response command is returned to the Control Head thatexecuted the PC command.NoteIn a Multi RF Deck system, if a PC command is executed from COM 1 or COM 2 of the Unselected RF Deck, some ofthe commands are restricted.16.10 External Ports (AUX Input/ Output)In a Multi RF Deck/ Multi Control Head structure, external devices such as Mobile Data Terminal (MDT) can be connectedby using the AUX Input/ Output port of the transceiver. (Refer to EXTERNAL PORTS.)The functions configured for a D-sub 25-pin connector behave only for the RF Deck connected to the D-sub 25-pin connector,regardless of whether the RF Deck is the Selected RF Deck or Unselected RF Deck. The functions configured for the 12-pin connector of a Control Head behave individually for the Selected RF Deck according to the configurations of thecommunication ports of each RF Deck.AUX function executedExternalSpeakerExternalSpeakerExternalSpeakerAUX function executedAUX function executedFigure 16-59 Example of When the AUX Input Is Configured for RF Decks16 MULTI RF DECK/ MULTI CONTROL HEAD16.9 Communication PortsCommon FUNC (K, F)/Ver 2.20 297CONTENTS INDEX
