  • Page 57 Figure 31 - RS-232 Remote Connection 9.3 Setting up the IEEE-488 Port for Remote Control The AMC910 is fully programmable for use on a standard IEEE-488 interface bus. The IEEE-488 interface is also designed in compliance with supplemental standard IEEE-488.2, which describes additional IEEE-488 features.
  • Page 58 Figure 32 - IEEE-488 (GPIB) Remote Connection 9.4 Changing Between Local and Remote Operation In addition to local mode (front panel operation) and remote, the AMC910 can be placed into a local lockout condition at any time by command of the controller.
  • Page 59 Front panel operation is disabled except for the LOCAL (0) key. Pressing the LOCAL key, using RS-232 to send the LOCAL command, or IEEE-488 to send the GTL (Go To Local) message, returns the AMC910 to the local state. d) Remote with Lockout State When the AMC910 is placed in lockout, either via a RS-232 LOCKOUT command, or via the IEEE-488 message LLO (Local Lockout), the AMC910 front panel controls are totally locked out.
  • Page 60 Several commands are used only for RS-232 serial operation because these functions must be implemented as IEEE uniline (single control line) bus management messages per the IEEE Standards. For example, the command REMOTE could be sent as data over the IEEE-488 interface to place the AMC910 into remote operating mode, but it is not because the IEEE Standards call for the remote function to be sent to the device as the uniline message REN.
  • Page 61 9.6 Using Commands Communications between the controller and the AMC910 consist of commands, queries, and interface messages. Although the commands are based on the 488.2 standard, they can be used on either the IEEE-488 or RS-232 interface, except for a few specific RS-232 only commands as described in the subsection Commands for RS-232 Only below.
  • Page 62 This command instructs the AMC910 to return the present DC voltage output range. d) Interface Messages (IEEE-488) Interface messages manage traffic on the IEEE-488 interface bus. Device addressing and clearing, data handshaking, and commands to place status bytes on the bus are all directed by interface messages.
  • Page 63 You can also use the status commands *OPC and *OPC? to detect the completion of overlapped commands. g) Sequential Commands Commands that execute immediately are called sequential commands. The detailed command descriptions in section 10 show a check mark T beside Sequential for sequential commands. The majority of commands are sequential.

  • Page 72 9) Output Queue The output queue is loaded whenever a query is processed, and holds up to 250 characters. The controller reads it with a statement such as a BASIC INPUT statement, removing what it reads from the queue. If the queue is empty, the AMC910 does not respond to the INPUT statement from the controller.
  • Page 73 RS-232 interface: The AMC910 uses the RS-232-C Xon/Xoff protocol to control buffer overflow. The AMC910 sends a Xoff (Ctrl S) character when the input buffer becomes 80% full, and sends a Xon (Ctrl Q) character when it has processed enough of the input buffer so that it is less than 40% full.
