4.0 ISP Cable considerations
The programmer is supplied with a single 10-way ISP Cable as standard. This cable is terminated
with a 10-way IDC 0.1” female polarised plug at each end. The cable is wired as a so-called ‘straight-
through’ cable with pin 1-1, 2-2 etc. The polarised ISP Header ensures that the ISP Cable cannot be
plugged in the wrong way around by mistake. If you are planning to design such a header onto your
Target System, it is strongly recommended that a similar polarised header is used. This will help to
prevent accidental damage to both the programmer and the Target System.
Pin 1 of the ISP cable can be determined by looking for a small arrow on the plastic part of the ISP
female plug. If the cable has a RED stripe on one cable, this usually also indicates pin 1.
If you are using the programmer in a production environment and constantly plugging / unplugging the
ISP cable into/from the Target System, you may find that the cable eventually fails. Spare ISP cables
can be ordered from Equinox in this eventuality.
