- I. Revision History
- ====================
- Rev 1.1.2: (08/23/95) Fixed a memory map resource leak on VXLink.
- The underlying map resource is now freed when a session
- is closed without first doing a viUnmapAddress().
-
- Rev 1.1.1: (06/20/95) Fixed a viReadStb() problem on RADI-EPC7.
-
- Rev 1.1.0: (05/02/95) First VTL 3.0 Release
-
-
- II. Software/Hardware Requirements
- ==================================
- This version requires the following hardware:
-
- PC Running Windows 3.1 or 3.11 in Enhanced Mode
- 4MBytes RAM
- 20MBytes Free Harddisk Space
-
- This version requires one of the following I/O interfaces:
-
- Radisys EPC-7 VXI Embedded PC Controller (VXI & HP-IB)
- HP RADI-EPC7 VXI Embedded PC Controller (VXI & HP-IB)
- HP E1483A VXLink VXI Interface
- HP 82340 HP-IB Card
- HP 82341A HP-IB Card
- HP 82341B HP-IB Card
- HP 82341C HP-IB Card
-
- The following I/O interface is specifically *not* supported:
-
- HP 82335 HP-IB Card
-
- In order to make use of the GPIB-VXI functionality (VXI
- communications from a GPIB interface), you need one of the
- following HP VXI Command Modules:
-
- HP E1405
- HP E1406
- HP E1300
- HP E1301
- HP E1303
- HP E1306
-
- This version requires HP SICL Revision B.03.11 or greater to be
- installed in order for the VTL software to function.
-
-
- III. Notes
- ===========
- - In order to receive interrupts that are being sent to your process,
- your process must yield the CPU. Most well-written Windows
- applications automatically do this at convenient locations.
-
- - %T does not work with this release, we recommend using %t instead.
-
- - The Fast Data Channel (FDC) protocol is not supported with this
- release.
-
- - Multiple GPIB instruments simultaneously generating SRQs on the
- same GPIB interface may cause loss of interrupts. This is not a
- problem if either the instruments do not generate SRQs simultaneously,
- or if they are on separate GPIB interfaces. This problem will be
- fixed in a future release.
-
- Platform Specific Notes:
- - GPIB:
- * HP 82335 GPIB card is not supported and does not work with this
- release.
- - GPIB-VXI:
- * Supported on HP E1405, HP E1406, HP E1300, HP E1301, HP E1303,
- and HP E1306 only. No other command modules are supported nor
- will they work with this release.
- * The VI_EVENT_VXI_SIGP and VI_EVENT_TRIG events are not supported.
- * The viAssertTrigger() command is not supported.
- - VXI on HP-VXLink:
- * The VI_EVENT_TRIG event is not supported.
- * The VXLink VXI cardcage should be powered on before running the
- configuration tool.
- - VXI on Radisys EPC7 and HP RADI-EPC7:
- * VTL automatically handles the EPC7 TTL trigger latch register.
- However, if a trigger line is asserted for more than one second
- during an appropriate viEnableEvent call, the call will fail and
- return an error.
- * If a trigger interrupt arrives, and VTL is unable to clear the
- trigger latch, then the trigger event is generated, but further
- trigger interrupts are disabled until an appropriate viDisableEvent
- followed by a viEnableEvent call is made.
- * For more information about the EPC7 TTL trigger latch register,
- please refer to your EPC-7 Documentation.
