Product Description
Product Name TC488/VMS, Version 1.0
TURBOchannel-IEEE-488-Interface for VMS
Description
The TC488/VMS is a low-cost, high-performance TURBOchannel
IEEE-488 converter for OpenVMS. It allows the usage of the
IEEE-488 bus on such members of the VAXstation4000 family, which
have a TURBOchannel adapter (e.g. VAXstation 4000/60 and
VAXstation 4000/90). The TC488/VMS connect instruments and
measuring devices, communicating via the IEEE-488 bus to the
TURBOchannel.
The TC488/VMS consists of the TC-GPIB-Board and the corresponding
device driver for OpenVMS. The TC-GPIB is a TURBOchannel board
which allows a standardized, bi-directional communication between
the TURBOchannel interconnect and the widely used IEEE-488 bus,
also known as the GPIB. This board is also used for the devices
IET11 from Digital Equipment Corporation and GPIB-DEC5000 from
National Instruments. The IEEE-488 circuits NAT488 and Turbo488
from National instruments are used for this board. With them it
is possible to realize all major IEEE-488 interface functions as
described in the IEEE-488.1 and IEEE-488.2 standards and to
provide enhanced DMA transfer capabilities with data transfer
rates of 1 Mbyte/second for both read and write operations. The
board supports up to 14 IEEE-488 bus devices directly.
The loadable device driver for OpenVMS (at least version 5.5-2)
allows the usage of all features of the board. This contains the
full interface functions of the IEEE-488 specification, in
particular the full talker, listener and controller capabilities.
The driver provides a QIO interface which is compatible to the
IEZ11 SCSI-IEEE488 converter from Digital Equipment Corporation.
Therefore it is possible to port applications written for the
IEZ11 easily and with no problems to the TC488/VMS.
The driver realizes the following functionalities
- read and write data over the IEEE-488 bus (data transfers)
- control and monitor the other devices (works as system
controller and Controller-In-Charge (CIC))
- works as peripheral device (talker and listener only)
- provides the possibility to poll the devices on the bus
serial or parallel (serial and parallel polling)
- detect the configuration of the IEEE-488 bus system
(detect and recognize connected devices)
- react to bus events (e.g. handle service requests)
- provides the possibility to request service
Furthermore there is an interface library for C programs which
contains NI488.2 compatible calls (the NI488.2 is the interface
standard from National Instruments for the IET11 and
GPIB-DEC500). It is possible to port with this library calls UNIX
based solutions for the IET11 to the VMS platform with the
TC488/VMS.
The TC488/VMS should be supported by the LIO routines and DECrti
(DEC Realtime Integrator). All DECrti and LIO routine based
applications which work with the IEZ11 can be used even with the
TC488/VMS.
Part of the TC488/VMS is also the test and maintenance programm
ITADS.
A VAXstation 4000 workstation, equipped with the TC488/VMS, is
well suited for instrument control applications where low-cost
and high-performance requirements are important selection
criteria. These applications can be found in research and
development laboratories, service laboratories, research
institutes, education, and government. Applications include data
acquisition systems, automated test equipment, and numerous
graphic applications.
For the installation of the TC488/VMS software the standard
procedure VMSINSTAL is used.

Additional Informations
Product Name TC488/VMS, Version 1.0
TURBOchannel-IEEE-488-Interface for VMS
Date 27. May 1993
1.) Availability
Field test versions are available in the middle of June (25. week of the year).
The first final versions are available 2 or 4 weeks later.
2.) Price
The price is the same as the price for the Ultrix version from National
Instruments : 2700,- DM (for the board and the software). It is possible to buy
the driver only. The price for this case can be obtained on request.
3.) Porting to Alpha (OpenVMS/AXP)
The TC488/VMS will be ported to OpenVMS/AXP and be named TC488/AXP. The portin
starts with the delivery of the first VMS version. The AXP version shall be
available in the summer (in August, 32. - 35. week of the year)
4.) Support
We provide support to develop special driver versions (e.g. for very time
critical real-time applications) and to develop customer solutions. Any special
driver versions can have their own QIO interface wich is optimized for the
desired solution to get the best performance or to provide the required
features.
