After supplying all your  Embedded Development Tool needs for 42 years
 Computer Solutions Ltd and its web shop are now closed.

  

 
 

 Having reached the grand old age of 75 it is time to relax and fulfil other ambitions.

 Its been an exciting ride with you, our customers, often on the bleeding edge of technology
 and I thank you for your friendship, your trust, and your orders.

Stay well        I wish you all success in your future projects.

     But what to do with the web site ?  It has taken >12 man years of work to create a repository of knowledge on many aspects of the art and science of embedded microprocessor development and even after closing the shop it still gets over 4,000 visitors per month.  So as a service to my customers I have decide to keep it live providing my technical insights on the products and then redirecting viewers to sites where they can purchase the items they used to buy from us. Follow the link   "Home"

       The  "Information zone"  consists of articles produced as background tutorials on subjects of interest to those designing new products.  As different CPUs have became available this has lead to new development techniques and in particular to new ways of communicating between nodes.

Configurable CAN Data Acquisition Units


 

This page describes the  Peak Industrial strength Data Acquisition systems that are configured via simple PC based Windows Applications.  The advantage of this configuration process is that no programming expertise is required and configurations may be rapidly created and changed.  They all need a PEAK-CAN interface for the initial loading of fresh configurations but after that can of course be read and written to by any valid CAN interface.

Large Industrial  I/O Modules

Thermocouple Unit

Advanced Router and Data Logger

 

 

It's a rather artificial separation but on our Programmable CAN Controller page we have a number of units that require the user to program the modules.  This gives much more control and flexibility but requires a greater investment in time to program the unit in C.

Industrial I/O Modules

These Industrial I/O modules use the PCAN MicroMod board described on another page to provide a ready made data acquisition system. They are available with a number of the most useful signal conditioning alternatives plus termination in an industrial case. At 51 x 60 x 20mm, they are suitable for a wide variety of applications.

Each unit is supplied with a preconfigured MicroMod board installed on a signal conditioning motherboard in an all-metal casing.  The electrical connections  provide snap-in termination; with a screw connection as an option.

Status LEDs show power supply and a single digital output

Speed is settable up to CAN High Speed typically 500k Bits/s and up to 32 Modules may be put on a CAN network.

Standard supply is push in connectors,  screw are available as an option.

CAN Open compatible firmware is also available at no extra charge for all Industrial modules.

 

Versions are available to suite a range of needs........
