4052R14 GPIB ENHANCEMENT ROM PACK. This might be described in the 1983 Tek Catalog, but I found this in Vol. 6 No. 2 Summer 1982 Tekniques: TEKTRONIX 4051R14 and 4052R14 GPIB Enhancement ROM Packs Expand Bus Control. Is your 4050 Desktop Computer acquiring data or controlling instruments over the IEEE-488 General Purpose Interface Bus (GPIB)? If so, a new ROM pack is sure to save you time and expand your capability. The ROM Pack comes in two versions: the 4051R14 with 41 new commands for the 4051, and the 4052R14 with 39 new com- mands ("MTPack" and "WAIT" are already built in) for the 4052 or 4054. A group of twelve commands improves GPIB polling by adding parallel polling, en- hancing serial polling, assisting blind poll- ing, decoding Tektronix Codes and Formats* standard instrument error messages and adding direct control over SRQ interrupts. Another twelve commands provide friendly interface with the GPIB by implementing the standard bus commands through "CALL" statements using the corresponding IEEE-488 mnemonics instead of WBYTE statements. The rest of the commands add routines par- ticularly valuable in GPIB environments. A brief look at a few of its functions will suggest the ROM pack's utility. A time-out parameter to the serial poll routine prevents unexpected bus conflicts when a device does not respond to a poll request. A new routine automatically determines what devices are on the GPIB and returns their primary, and optionally their secondary addresses. This allows programs to check the availability of all necessary equipment before data collection or transmission. The CALLs for GPIB functions use common names such as "IFC" for Interface Clear and "SDC" for Selected Device Clear. Instruments may be selected as talkers or listeners through the CALL "TALK" or "LISTEN" commands. Binary data may be transferred in either packed or unpacked form. Hexidecimal conversions are easy and fast. Utility routines provide better control of tape operations such as named tape files or LAST file search. Array sizes may be determined with the CALL "ARSIZE" command. The bit manipulation routines which set, clear, and test individual bits in a variable promote easier data transmission to and from devices on the GPIB. I'll ship this in a USPS Padded Flat Rate Envelope (with two pieces of cardboard protecting the ROM pack...inside the Bubble Envelope) with Tracking information.
