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.

Chris Stephens.



     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.

CAN Cables, Connectors, Converters
Isolation & Termination

We can provide cables, (terminated or not) that conform to the ISO standard CiA-DS102 as well as opto-isolation and converters to TJA1054.


High quality CAN cables suitable for use at 1MHz are available in standard lengths or built to order with or without termination.  Pin assignment according to CiA-DS102

CAN Cable CAN Connection Cable 2.0 m, 9-pin Sub-D female plug on both ends, each terminated with an 120 Ohm resistor. (so only suitable for connecting a single node to an interface at high speed)

CAN Connection Cable 2.0 m, 9-pin Sub-D female plug on both ends, without terminating resistors.
CAN T junction T-Adapter for tapping into CAN networks, 9-pin Sub-D female plug to 9-pin Sub-D female and 9-pin Sub-D male, without terminating resistors.
OBD-2 cable Converts the 9-pin Sub-D socket (to CiA DS102-1) to the OBD-2 connector 

– assigned for CAN only -  Pin 6: CAN high,  Pin 14: CAN low (J-2284) 
Without termination resistors

  J1939 cable




PCAN-Cable J1939
A 1M cable without termination resistors. It converts the 9-pin Sub-D socket (to CiA DS102-1) to the J1939 9 pin DEUTSCH HD series connector (not an ISO standard but becoming the most popular).


CAN Termination Adapter, 9-pin Sub-D male plug, terminated with a 120 Ohm resistor.




CAN isolation The PCAN-Optoadaptor provides a galvanic separation on a CAN-bus system of up to 500V.  It is enclosed in a small 9-pole to 9-pole housing.



Please note that the following adapters / converters only change the signals to match the voltage/current requirements of the different standards you will still have to run both sides at the lower of the two speeds.


BUS Converters (TJA1054 or AU5790)


TJA1054 Converts interfaces with buffers capable of running high speed CAN to the low speed, low power TJA 1054 standard with PCA82C252, TJA1053 or TJA1054 transceivers.  The TJA1054 Low Speed transceiver always runs in normal operating mode. It cannot be switched to Sleep mode or Standby mode.

AU5790 Converts interfaces with buffers capable of running high speed CAN to connect  with systems using the AU5790 transceiver. 

CAN TJA 1054 adapter


CAN converter from high speed to Truck Trailer CAN ISO 11992-1

Truck Trailer Converter


The PCAN-B10011S bus converter links a high-speed CAN-node and a truck trailer CAN bus (ISO 11992-1)Specification. It provides direct connection to a 9-pin HS-CAN, switch able termination of the HS-CAN.  Connection of the Truck Trailer CAN via 9-pin Sub-D connector with a choice of operating modes for the Truck Trailer CAN via a slide switch
Data transfer rates can be up to 125 kBit/s, power supply is via the Truck Trailer CAN-bus or an external PSU.  There is a status display for power supply and error states via LEDs
