SERIES PMC230 PCI MEZZANINE CARD 16-BIT HIGH-DENSITY ANALOG OUTPUT MODULE

___________________________________________________________________________________________

- 12 -

The Calibration PROM contains channel specific calibration

coefficients to correct both offset and gain errors. The coefficients
must be used to trim the outputs to within their accuracy
specification. The PROM, software registers, and DAC’s are all
accessed through the PCI bus interface.

PMC Module Software

Acromag also provides a software diskette (sold separately)

consisting of PMC module ActiveX

controls for Windows 98, 95

ME, 2000 and Windows NT

compatible application programs

(Model PMCSW-ATX, MSDOS format). This software provides
individual controls that allow all PMC modules to be easily integrated
into Windows

application programs, such as Visual C++

™

, Visual

Basic

, Microsoft

Office

97 applications and others. The

ActiveX

controls provide a high-level interface to PMC modules,

eliminating the need to perform low-level reads/writes of registers,
and the writing of interrupt handlers—all the complicated details of
programming are handled by the ActiveX

controls. These functions

consist of an ActiveX

control for each Acromag PMC module.

In addition, Acromag provides a software product (sold

separately) consisting of PMC module VxWorks

libraries. This

software (Model PMCSW-API-VXW MSDOS format) is composed
of VxWorks

(real time operating system) libraries for all Acromag

PMC modules. The software is implemented as a library of “C”
functions which link with existing user code to make possible simple
control of all Acromag PMC modules.

5.0 SERVICE AND REPAIR

SERVICE AND REPAIR ASSISTANCE

Annual return of the PMC230 to Acromag for

re-determination of the calibration coefficients is highly
recommended. Corrected data accuracies depend heavily on the
calibration coefficients being within specification. Field
determination of calibration coefficients requires precision test
equipment. Contact Acromag for technical assistance if field
recalibration is needed.

Surface-Mounted Technology (SMT) boards are generally

difficult to repair. It is highly recommended that a non-functioning
board be returned to Acromag for repair. The board can be easily
damaged unless special SMT repair and service tools are used.
Further, Acromag has automated test equipment that thoroughly
checks the performance of each board. When a board is first
produced and when any repair is made, it is tested, placed in a burn-
in room at elevated temperature, and retested before shipment.

Please refer to Acromag's Service Policy Bulletin or contact

Acromag for complete details on how to obtain parts and repair.

PRELIMINARY SERVICE PROCEDURE

Before beginning repair, be sure that all of the procedures in

Section 2, Preparation For Use, have been followed. Also, refer to
the documentation of your carrier/CPU board to verify that it is
correctly configured. Replacement of the module with one that is
known to work correctly is a good technique to isolate a faulty
module.

CAUTION: POWER MUST BE TURNED OFF BEFORE
REMOVING OR INSERTING BOARDS

Acromag’s Applications Engineers can provide further technical

assistance if required. When needed, complete repair services are
also available from Acromag.
