4.3.1 Communication principle
MI 2893/MI 2892/MI 2885 instrument use Ethernet port for connection to PowerView through internet.
As companies frequently use firewalls to limit internet traffic options, whole communication is routed
through dedicated “Metrel Route Server”. In this way instrument and PowerView can avoid firewalls and
router restrictions. Communication is established in four steps:
1. User selects INTERNET or INTERNET (3G/GPRS) or INTRANET (LAN) connection under
COMMUNICATION menu, and checks if connection to Metrel server can be established (Status
bar icon should appear within 2 minutes).
Note: Outgoing ports 80, 443, 7781 ÷ 8888 to the gprs.metrel.si server should be opened on
remote firewall where instrument is placed!
2. User enters instrument serial number on PowerView and connects to the instrument over
Metrel server.
Note: In case of using accessory A 1622 3G Wi-Fi modem for internet connection, please check A
1622 instruction manual in order to properly set up modem, before using it.
