  • Page 40 Note that you do not need to use a crossover cable to connect your PC to this module if the Acromag 900EN-S005 switch is used between the PC and module, as the switch is auto-crossing. However, you must use a crossover cable when directly connecting your PC to a Series 9xxEN I/O Module without the use of an auto-crossing switch or hub.
