Serial RS-232 connection
3.5.10.2 Recommendation for wiring
a) If you build the serial cable, you can use a 3-wire shielded cable with shield connected to BOTH ends. Do not
use the shield as GND. The ground wire must be included inside the shield, like the 232Rx and 232Tx signals
b) Always power-off all the iPOS360X supplies before inserting/removing the RS-232 serial connector
c) Do not rely on an earthed PC to provide the iPOS360X GND connection! The drive must be earthed through
a separate circuit. Most communication problems are caused by the lack of such connection
