Section 6 Remote interface 6.1 INTRODUCTION 6.2 RS232C INTERFACE 6.3 RS232C OPERATION 6.4 IEEE-488 OPERATION 6.5 INTRODUCTION TO SCPI LANGUAGE 6.6 COMMAND SUMMARY 6.7 MANDATORY COMMANDS 6.8 INSTRUMENT COMMANDS 6.9 IEEE-4888 COMPLIANCE INFORMATION 6.10 SRQ HANDLING DETAILS 6.11 ERROR MESSAGES & REPORTING 6.12 APPLICATION PROGRAM EXAMPLES 6.
6.2 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 (abbreviated 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. I.e. the TXD and RXD lines are cross-connected to the Host controller.
6.3.1 RS232 Data Format One Start Bit 6.3.2 8 Data Bits No Parity Bit 1 Stop Bit 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.
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.
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 = Indicates Null or space character (20H) = Indicates Arbitrary ASCII Response Data = Indicates Numeric Data = Indicates End of string character (ODH) 1.
4. Command: VOLT: PROT Description: Set Over Voltage Protection Limit of OUTPUT Function: This command sets the Over Voltage Protection Limit of the Power Supply output with the 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’. I.e.
9. Command : STAT? Description: Read Status Query. Function: This command reads the status of various events occurred in the system. The definition of events is given below B0: B1: B2: B3: B4: B5: B6: B7: Over voltage Trip Over Temperature Trip Power On event (Sets when unit is turn ON. The bit gets cleared after the quarry.
6.4.1 IEEE-488 Interface Configuration The IEEE-488 Interface is a parallel BUS for Communication in the Programmable 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.
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 (IEEE488) bus. Refer FIG. 6.3 for connector types definition diagram. Description of the GPIB Signals is given below. PIN NO.
6.4.3 IEEE-488 Operational Sequence Guidelines Most interface communication tasks require a sequence of coded messages 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. Different controllers will not necessarily have identical sequences or program instructions. The following sequences are recommendations only.
UNL SPE SPD SBN SBA 6.4.4 = = = = = Unlisten Serial Poll Enable Serial Poll Disable Status Byte Negative, where BIT 6 = 0 (BIT 7 is the MSB) Status Byte Affirmative, where BIT 6 = 1 (BIT 7 is the MSB) Installation procedure for GPIB interface option in the VSP series power Refer to the general assembly layout of the VSP series power supplies. In the standard units RS232 interface is provided by default. Accordingly, at the location no. 12 the RS232 interface card (ISO-RS232 CONV-0304A) is installed.
f) Compile the project. g) Connect line input to the unit. Keep the front panel output ON/OFF switch in OFF position. Turn the unit on with the input ‘Line’ switch. h) Run CSPY to download program in flash memory of the controller. i) j) Press the RESET button in the window and exit from CSPY. Turn OFF the unit & remove JTAG connector. This will complete the software installation for GPIB option.

VSP-DPM-CONT To J7 To J5 To J1 of VSP-POT-IMON To J1 of INSTR-TO-GPIB 6.4.5 IEEE-488 Instrument Address Selection The instrument address is set manually using an eight way miniature switch near the interface connector on the rear panel. This DIP switch is normally marked with A0 to A7 to identify the proper switch. In our system, we refer A0 as switch 1 and an A7 as switch 8.

6.4.6 Special Notes For the Controller Software Writer This section will provide some valuable hints to the controller software program writer for interfacing this Programmable Unit, through the communication interface. 1). Normal communication is in ASCII. The unit will accept both the lower case and upper case characters. 2). All commands for the units are in the IEEE-488.2 and SCPI format. 3). All mandatory commands for IEEE-488.2 are implemented in the unit. 4).
13). Before sending the unit into talk mode it is also advisable to Flush out the controller’s data-in buffer by giving a dummy read. This is required because some controller can keep the last data latched into its data-in Buffer. 14). If you send more than one query in a , only the LAST correct query will be processed and response will be given for last query. 15). No response can be read without giving a query. Otherwise the query error bit will be set & an error message is generated. 6.
USING WHITESPACE You must use Whitespace characters, [tab], or [space] to separate a parameter from a command keyword. Whitespace characters are generally ignored only in parameter lists. USING “?” COMMANDS The BUS controller may send commands at any time, but an SCPI instrument may only send responses when specifically instructed to do so. Only QUERY com mands (commands that end with a “?”) will instruct the instrument to send a response message.
DISCRETE PARAMETERS: Discrete parameters are used to program settings that have a limited number of values (like BUS, EXTernal, NORmal, and INVerted). They have a short forms and a long form just like command keywords. You can mix upper case and lower-case letters. Query responses will always return the short form in upper-case letters. BOOLEAN PARAMETERS: Boolean Parameters represent a single binary condition that is either TRUE or FALSE. For a false condition the instrument will accept “OFF” or “0”.
6.5.4 SCPI Status Model All SCPI instruments implement status registers in the same way. The status system records various instrument conditions in three register groups: The Status Byte register The Standard Event register and The Questionable Data register. The status byte register records high level summary information reported in the other register groups. The diagram on the next page illustrates the SCPI status system.
SCPI STATUS SYSTEM 40
The Status Byte Register The status byte summary register reports conditions from other status registers.Query data that is waiting in the instrument’s output buffer is immediately reported through the “message available” bit (bit 4). Bits in the summary registers are not latched. Clearing an event register will clear the corresponding bits in the status byte summary register. Reading all messages in the output buffer, including any pending queries will clear the message available bit.
TO INTERRUPT YOUR BUS CONTROLLER USING SRQ * * * * * Send a bus device clear message. Clear the event registers with the *CLS (clear status) command. Set the *ESE (standard event register) & *SRE (status byte register) enable masks. Send the *OPC? (Operation complete query) command and enter the result to assure synchronization. Enable your bus controller’s IEEE-488 SRQ interrupt. TO DETERMINE WHEN A COMMAND SEQUENCE IS COMPLETED.
Note: An error condition (standard event register bits 2,3,4 or 5) will always record one or more errors in the instrument’s error queue. Read the error queue using SYSTem: ERRor? The standard event register is cleared when: * You send a *CLS (clear status) command. * You query the event register using the *ESR? (Event status register) command. The standard event enable register is cleared when: * * You turn on the power to the instrument. You execute a *ESE 0 command.
