  • Page 18: Implemented Status Structures

    SX8 User Manual Implemented Status Structures There are three distinct status data structures implemented in the SX8 switch:  IEEE 488.2 defined standard registers (standard status structure)  SCPI defined operation registers (operation status structure)  SCPI defined questionable registers (questionable status structure) The 488.2 standard status structure consists of four registers: ...
  • Page 19 SX8 User Manual Status Byte Register The status byte register contains the summary bits for each of the structures implemented in the switch, the master summary bit (MSB) and the request for service bit (RQS). Status Register Bit 7 Bit 6 Bit 5 Bit 4 Bit 3...
  • Page 20 SX8 User Manual  Bit 7 (operation summary bit) is the summary bit for the operation status register. It is set if any bit in the operation event register is set while the corresponding bit in the operation event enable register is set.
  • Page 21 SX8 User Manual  Bit 3 (device dependent error) is set by the switch to indicate that an error has occurred that is not a command error, an execution error, or a query error.  Bit 4 (execution error) is set when an execution error is detected by the switch, for example, if a command parameter is out of the range of the switch or a valid program message cannot be executed due to some condition in the switch.
  • Page 22 SX8 User Manual Operation and Questionable Event Registers Event registers reflect changes in the conditions of the switch. Each bit in the operation event register and the questionable event register is associated with a bit in the corresponding condition register. Depending on the values of the positive transition register and the negative transition register, a bit in the event register can be set when the associated bit in the condition register changes from 0 to 1, from 1 to 0,...
  • Page 23 SX8 User Manual Operation and Condition Positive Transition Register If a bit in the positive transition register is set, then a positive transition (a transition from 0 to 1) in the associated bit in the condition register sets the associated bit in the event register.

  • Page 24: Queues

    SX8 User Manual Queues Input Queue The input queue in the switch is a first-in-first-out (FIFO) queue and is 256 characters in length. Data bytes received from the controller are placed in the input queue in the order received. When a full message unit is received, it is transferred to the parser.
