Communication Port Pinout Diagrams
Cables are available that allow you to quickly and easily connect a Handheld Programmer or
a personal computer to the DL06 PLCs. However, if you need to build your cable(s), use the
pinout descriptions shown below, or use the Tech Support/Cable Wiring Diagrams located
on our website. The DL06 PLCs require an RJ-12 phone plug for port 1 (D2-DSCBL) and a
15-pin SVGA DSub for port 2 (D2-DSCBL-1).
The DL06 PLC has two built-in serial communication ports. Port 1 (RS232C only) is
generally used for connecting to a D2-HPP,
Direct
SOFT
,
operator interface, MODBUS
slave only, or a
Direct
NET slave only. The baud rate is fixed at 9600 baud for port 1. Port
2 (RS232C/RS422/RS485) can be used to connect to a D2-HPP,
Direct
SOFT, operator
interface, MODBUS master/slave,
Direct
NET master/slave or ASCII in/out. Port 2 has a
range of speeds from 300 baud to 38.4K baud.
NOTE: The 5v pins are rated at 220mA maximum, primarily for use with some operator interface units.
