terminated string that represents the exact voltage of the on 
board reference circuit as measured and stored at the factory. 

 

PMC Module Software 

 

Acromag also provides a software diskette (sold separately) 

consisting of PMC module ActiveX drivers for Windows 98, 95

ME, 2000 and Windows NT

 compatible application programs 

(Model PMCSW-ATX, MSDOS format).  This software provides 
individual drivers 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

 drivers.  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 

 

The PMC341 is shipped pre-calibrated by Acromag and may 

be returned at the discretion of the customer to measure the 
accuracy of the calibration at some defined period. Recalibration, 
if required, can be performed by the customer if the proper 
equipment is available to them and is otherwise offered through 
the Service Department at Acromag for a fee.   

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.
