    Unused slots in the System 10/20 chassis are populated with blanking plates to prevent access to user I/O signals that may be present. Blanking panels are available to order from Pickering in a variety of slot widths. If the product is not used in this manner for example by using an extender card then additional care must be taken to avoid contact with exposed signals.

    The module is designed for indoor use only. PRE-OPERATION CHECKS (UNPACKING) 1. Check the module for transport damage and report any damage immediately to Pickering Interfaces. Do not attempt to install the product if any damage is evident. 2. Position the chassis relative to any other equipment the module(s) will connect with. Ensure the chassis is not connected to the electrical supply.
  • Page 16 The Interface should be installed in accordance with the following procedure: 1. Ensure that the system is turned OFF but still connected to mains so that it remains grounded. 2. Insert the Interface Module into the relevant chassis position detailed in the Pickering 10-910M IEEE-488 GPIB System 10/20 Ancillaries manual.

  • Page 19: Programming

    System 10/20 conforms. If a full and rigorous description is required the user should refer to that standard. The basic element used in programming System 10/20 is the program instruction. A program instruction consists of a sequence of data bytes sent to System 10/20 which form a command which is recognised by System 10/20. e.g. “WRITE 1,5”.
  • Page 20 Response Messages System 10/20 returns data to the controller in the form of a response message . A response message consists of a sequence of bytes, terminated by a response terminator which is defined as a newline data byte (ASCII character 10 decimal) sent with IEEE 488.1 <EOI>.
  • Page 21 Buffer Overflows Should System 10/20 be asked to buffer more data than it is able, because the controller sends an extensive query message which fills the System 10/20 output buffer with response data, and continues sending until the input buffer is also full, an error is detected (BUFFERS DEADLOCKED).

    System 10/20 will still be waiting for the message to complete, which would appear as a lock-up or time out error. To place System 10/20 back into a known bus state the controller must issue the SDC (Selective Device Clear) command - this is true for all IEEE-488.2 instrumentation-.
  • Page 40 Only multiplexer modules with a firmware revision number of 2.00 or greater support this function. Most multiplexer modules shipped after Jan. 1991 support this feature, if you have an earlier version please contact Pickering for a free upgrade EPROM. Multiplexers not supporting this feature include 1 pole and many RF types.
  • Page 41 SECTION 8 - TROUBLE SHOOTING pickering Solution #2: High voltage transients entering switching modules either via signal conductors or earth/shield lines can upset switching modules (usually the built-in microprocessors). High voltage switching modules have extensive suppression built-in, so provided the module is not subject to excessive voltages there should be no problem.
