    Section 6 Remote interface INTRODUCTION RS232C INTERFACE RS232C OPERATION IEEE-488 OPERATION INTRODUCTION TO SCPI LANGUAGE COMMAND SUMMARY MANDATORY COMMANDS INSTRUMENT COMMANDS IEEE-4888 COMPLIANCE INFORMATION 6.10 SRQ HANDLING DETAILS 6.11 ERROR MESSAGES & REPORTING 6.12 APPLICATION PROGRAM EXAMPLES Introduction VSP series power supplies are configured for either RS232C or GPIB as per the order placed (refer chapter 1 for ordering information).
  • Page 25 RS232C INTERFACE: The basic principle of RS232C operation is achieved by 3-wire interface. The 3-wire interface comprises of transmit pin (abbreviated as TXD), receive pin (abbre- viated as RXD) and a common ground pin (GND). TXD pin of host is connected to the RXD pin of the instrument and the RXD pin of the host is connected to the TXD pin of the instrument and the third line connects the GROUNDs of the two sides.
  • Page 26 6.3.1 RS232 Data Format One Start Bit 8 Data Bits No Parity Bit 1 Stop Bit 6.3.2 RS232 Connector Details On the rear panel of the unit, a 9 pin D-type male connector is provided for the RS232 communication. The DSR and DTR handshake lines are not used. But the interface cable which connects the COMM INTF on the instrument to the PC COM port (COM 1 or COM 2) should interconnect the RXD and the TXD line, such that the RXD input the instrument is the TXD output of the host controller or PC.
  • Page 27 6.3.3 INSTALLATION OF RS232 CARD The RS232 Interface (ISO_RS232_CONV-1103 Card) card may come already installed, if ordered. If this interface is to be installed later, the card can be mounted on the rear panel of the unit using L-clamp provided on the card itself & following cards &cables shall be provided along.
  • Page 28 6.3.4 RS232 Commands Following section deals with the commands set for RS232 interface. It specifies the syntax of each command, which reads the status of power supply or configures it to the requirements of users. NOTE: The command uses following notations <SP>...
  • Page 29 Command: VOLT: PROT<SP><NR.DATA><EOS> Description: Set Over Voltage Protection Limit of OUTPUT Function: This command sets the Over Voltage Protection Limit of the Power Supply output with the <NR.DATA> given in the command in Volts. The input VOLTAGE data is in Numeric Data format. Once this OVP limit is set, any time if the actual Output Voltage of the channel exceeds the OVP limit, the OUTPUT will be ‘TRIPed’.
  • Page 30 Command : STAT? <EOS> Description: Read Status Query. Function: This command reads the status of various events occurred in the system. The definition of events is given below Over voltage Trip Over Temperature Trip Power On event (Sets when unit is turn ON. The bit gets cleared after the quarry.) Internal Failure Always 1 (THIS STATUS BIT MAY BE CHANGED IN FUTURE)
  • Page 31 6.4.1 IEEE-488 Interface Configuration The IEEE-488 Interface is a parallel BUS for Communication in the Program- mable Instruments. Multiple instruments can be connected on the same BUS and can be hooked up to a single HOST controller or computer. In order that instruments from different manufacturers can be built into the same system, it was necessary that all interfaces be compatible.
  • Page 32 6.4.2 IEEE-488 Connector Details The instrument provides a standard 24 pin GPIB connector (marked as COMM INTF on the rear panel of the instrument) to connect it with the standard GPIB (IEEE- 488) bus. Refer FIG. 6.3 for connector types definition diagram. Description of the GPIB Signals is given below.
  • Page 33 6.4.3 IEEE-488 Operational Sequence Guidelines Most interface communication tasks require a sequence of coded mes- sages to be sent over the interface. It is recommended that a careful study of the available controller capabilities be made many of them assigning one programming instruction to these sequences.
