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 (pin 31 of J4) must be included inside the shield, like the 232Rx and 
232Tx signals 

b)  Always power-off all the iPOS4808 supplies before inserting/removing the RS-232 serial connector  
c)  Do not rely on an earthed PC to provide the iPOS4808 GND connection! The drive must be earthed through a 

separate circuit. Most communication problems are caused by the lack of such connection
