Idec / Izumi PLC series FA2, FA2J and FA3J all require a special
communication adapter for programming. This communication link adapter
(CLA) is a small box that converts the RS232 electrical signals into a
compatible level for the PLC. The cable to connect the PC to a CLA uses a
DB25 connector at the PLC side. The layout for a cable with a DB9
connector at the PC side is shown here.

Z-World micro-controllers
Z-World is an American company specialized in developing
micro-controller boards based on the Z180 and Rabbit series
micro-controllers. Where PLCs are often used in single piece
environments, micro-controllers are mainly present in the OEM world
where multiple controllers are needed.
The main difference in programming a PLC is that most
micro-controllers, including those from Z-World, are programmed in C.
The Z-World programming package runs on a normal PC and the connection
with the controller is made using a serial cable. This cable needs a DB9
connector at one and, and a RJ14 plug at the other. The pin out of a
programming cable is shown here.
