Cables are available that allow you to quickly
and easily connect a Handheld Programmer or
a personal computer to the DL105 PLCs.
However, if you need to build your own cables,
use the pinout diagrams shown. The DL105
PLCs require an RJ-12 phone plug to fit the
built-in jacks.
The Micro PLC has one built-in RS232C
communication port. The port is generally used
for programming either with the Handheld
Programmer or Direct SOFT, and has a fixed
station address of 1. The baud rate is fixed at
9600 baud. This port supports the K--sequence
protocol, which is a proprietary protocol.
