Appendix I – PC Comms Wiring
A PC may be connected to the PLM by connecting to the 9 pin female
connector as shown below. This allows the PLM to be configured using the
PLM Configuration software.
It is also acceptable to use a standard 1:1 male to female communications
cable which connects all 9 pins.
Note that during configuration the PLM must also have power connected to it via
the PLM 9 pin male connector.
