CPU Hardware Setup
Communication Port Pinout Diagrams
Cables are available that allow you to quickly and easily connect a Handheld Programmer or a
personal computer to the DL205 CPUs. However, if you need to build a cable(s), use the
pinout descriptions shown on the following pages. You can also use the Tech Support/Cable
Wiring diagrams located on our website.
The DL240, DL250–1 and DL260 CPUs have two ports while the DL230 has only one. All
of the CPUs require at least one RJ-12 connector. The DL250-1 and DL260 require one 15
pin D-shell connector.
