4. SETUP
KR-04 converter setup is carried out using Network Enabler Administrator PC software
(installed on a computer). The computer and the converter communicate via Ethernet.
Procedure:
1. Install Network Enabler Administrator PC software.
2. Establish communication between the computer and the converter via LAN, use crossed
cable terminated with RJ45 connectors on both sides. For KR-04-3 converter use
RADWAG-manufactured P0198 cable and a switch.
3. Connect the converter to the mains.
4. Run Network Enabler Administrator PC software.
5. Click „Zoom” icon, the software will search for network-connected converters.
