Can I use a standard RS 232 instead the Nera interconnection cable between the IDU and the ODU?
No, this is highly discouraged. Normal RS232 cables do not have any IP grading and may have incorrect electrical characteristics, which potentially could damage the terminal. Nera provide IDU-ODU cables in 3 lenghts of IP graded; 3m (Part No 107425), 10m (Part No 106495) and 20m (Part No 107450) Note: The warranty will be void if damage is caused to the WorldPro product by using it with unofficial equipment.
