3.2.3 ISPnano Series I - connecting to the RS232 Serial Port (RJ11)

If the programmer is being used in an environment where the RS232 cable will be regularly plugged in
and unplugged, then it is safer to use the 'RS232-2 Serial Port'. This port features a robust RJ11
connector which can withstand many insertions and de-insertions. The programmer comes with an
'RJ11 to 9-way D-connector' Serial Cable and also a '9-way serial extension cable'. The
combination of these two cables is used to connect the programmer to the PC COM port.
Instructions
Plug the 'RJ11 to 9-way D-connector' into the RJ11 connector port (RS232-2) on the
•
programmer (see diagram below).
Connect the other end of the cable to the '9-way D-connector Serial Cable'
•
Connect the other end of the '9-way D-connector Serial Cable' to a spare COM port on your
•
PC.
