Cabling Information
This chapter describes how to connect your computer to a DL5.
You will need a cable to connect your computer’s COM1 serial port to the
RS-232 port on the DL5. The Off-line Programmer automatically uses the
COM1 port for all communication functions including: setting the baud rate
of the DL5, using your computer in Terminal Mode, and reading and writing
files between your computer and the DL5. Consult your computer’s user’s
manual if you are not sure which port is COM1.
We recommend using an Allen-Bradley serial communications cable to
connect your computer to a DL5. These cables provide the 9-pin “D” shell
connections for your DL5’s RS-232 port and a “D” shell connector to plug
into your computer.
There are four cables available for serial communications connections to the
DL5’s serial port. See Table 3.A for catalog numbers.

You can construct your own cable according to the information provided in
this section. The RS-232 serial port is accessible via a 9-pin subminiature
male D-shell connector. The pin connections for cabling between the DL5
and various computer systems are included in this chapter.
NOTE: A shielded cable is recommended to ensure accurate data
transmission.
