Capstone Capstone Turbine Corporation 6025 Yolanda Avenue Tarzana, CA 91356 Connector used on Capstone MicroTurbine: DB25-P Pin Connection Name Value Notes or Conditions I/O Classification 6 DSR (Data Set Ready) 7 SG (Signal Ground) 8 DCD (Data Carrier Detect) 20 DTR (Data Terminal Ready) 22 RI (Ring Indicator) +/- 12V Gnd (0 V) +/- 12V +/- 12V +/- 12V Input N/A Input Output Input Dry circuit Dry circuit Dry circuit Dry circuit Dry circuit Table 2 -MicroTurbine Maintenance Port Signal Definitions 1.3 RS232 USER/MAINTENANCE PORT COMMAND LINE INTERFACE 1.3.1 Command Structure The basic paradigm of the communications interface is query-response from a prompt message, with the external device providing the query to the Capstone MicroTurbine DPC. In some unusual cases, a message on the maintenance port may be initiated by the DPC. (Example: The DPC is connected via dial- up connection to a central monitoring station, and a fault occurs. The DPC would initiate a call to the maintenance center via the maintenance port). Each query sent to the DPC contains a message. A typical message consists of a command, an optional turbine identification number, and command arguments. Arguments provide additional information to process the command. where, -> [,] [=] -> 6 ASCII characters identifying function to execute -> turbine number -> sequence of ASCII text supplied to the . See details on commands defined below. All white space characters (includes carriage return, line feed, space, and tab characters) are ignored by the DPC. In a multiple unit environment, all external devices connect to the master device2. Communications to other units in a multiple unit installation is routed automatically through the master unit. The master unit is always number 0. 1.3.2 RS232 Query Protocol Data transmissions over the RS232 interfaces are protected with a proprietary communication protocol syntax that encapsulates each message. Error detection is provided in the protocol through ASCII character message synchronization and a verification checksum. Error correction3 is performed by re- 2 Methodology for determining the master unit is beyond the scope of this specification. 3 This is the responsibility of the external device. No response is returned in the case of protocol error detected by the DPC. 1-3
