  • Page 70 The Digital Interface is user configurable as inputs or outputs in eight bit bytes. Interface configuration and data transfer is done by commands received from the GPIB bus or Serial interface. The 4807/2307/4867/2367 are no data handshake or strobe lines. The commands transfer data by direct byte (port) access or as strings of data characters.
  • Page 71 which in turn will set bits in the Status Byte Register. If the corresponding Status Byte Enable bits are set, then Service Request bit will be set and generate an SRQ. The user can serial poll or query the Status Byte to determine the source of the SRQ and take the appropriate action.
  • Page 72 SCPI commands is that they are common to a wide variety of instruments and are self documenting in the program listing. Most of the SCPI commands or queries have a corresponding short form command for ease of programming. Where possible, the short form commands are the same as those used other ICS Interfaces.
  • Page 73 UPDATE command or by the *RCL 0 command. The 2307/2367 provides a Service Request Message (SRM ) as a substitute for the 4807's SRQ signal. The SRM message contains the value of the Status Byte so the user does not have to query the 2307/2367's Status Byte Register.
  • Page 74 '1'. Summary lines from the three event registers cascade down to set bits in the Status Byte Register. When enabled, the 4807/4867 pulls the SRQ line low to signal the bus controller that an event has occurred and/or that the 4807/4867 needs service. The 2307/2367 sends its controller the SRM message to signal that it needs service.

  • Page 83 SCPI CONFORMANCE INFORMATION The 4807/2307/4867/2367 accepts SCPI commands and command extensions to configure its digital interface, to set the data formats and to transfer data. The SCPI commands conform to SCPI Standard 1994.0 and provide an industry standard, self-documenting form of code that makes it easy for the programmer to maintain the application program.
  • Page 84 SHORT FORM COMMANDS The unit also accepts short form commands which invoke the same action as do the corresponding SCPI commands. The short form commands are one to three characters long and are not case sensitive. The short form commands have the advantage of reduce the typing load on the programmer when operating the interface from a terminal or from a terminal emulation program.

    SERIAL DATA COMMUNICATIONS BACKGROUND A2.1 INTRODUCTION TO SERIAL COMMUNICATION Serial data communication is the most common means of transmitting data from one point to another. In serial communication systems, the data word or character is sent bit by bit over some kind of transmission path. The receiving device recognizes each bit as they are received and reassembles them back into the original data word.

Devices employing the same interface standard can usually be connected together but the user must verify each devices signal requirements before plugging them together.

  • Page 147: Rs-232 Standard

    With asynchronous characters, the receiver normally uses the start bit to synchronize its internal clock. However, some devices, such as the higher speed modems, require the data bits to be synchronized with their clock. These units are referred to as synchronous modems (not the same as synchronous data characters) and they will supply the clock signals to both the transmitting and receiving device.
  • Page 148 revision of this standard (RS-232) has been in effect since 1969 and is known as RS-232C. It specifies: Mechanical characteristics of the interface Electrical characteristics of the interface A number of interchange circuits with descriptions of their functions The relationship of interchange circuits to standard interface types The specification does not mean that two devices that are RS-232 compatible can be connected together with a standard cable and be expected to work.

  • Page 149: A2.3 Rs-422 And Rs-485 Standards

    In Europe, the Comite Constultatif International Telephonique it Telegraphiqe (CCITT) has established standards that correspond to RS- 232C. While these standards, CCITT V.24 and CCITT V.28, are very similar to RS-232C, they are not identical. The Model 4984 conforms to both RS-232 and CCITT V.24 standards, but does not contain or use all of the circuits allowed for in both standards.

  • Page 150: A2.4 Rs-530 Pinouts

    A2.4 RS-530 PINOUTS In 1987, the EIA released a new standard, EIA-530, for high speed signals on a 25 pin connector. This new standard combined the older RS-232 single-ended signals and the newer RS-422/RS-485 differential signals on one connector. The advantage of the RS-530 specification is that it established a pin out standard for RS-422/RS-485 signals on a 25 pin connector and at the same time provided for the presence of both signals on the same connector.
