The ESI-50 has a built-in IVC12. It can support up to 12 IP channels, which can be a combination of local IP, remote IP, and Esi-Link channels. The channels are activated in blocks of four for local IP, singles for remote IP, and four or twelve for Esi-Link. Here is an example of some possible ESI-50 IVC12 channel combinations:
• 12 all Esi-Link.
• 12 all local IP.
• Eight Esi-Link, four local IP.
• Four Esi-Link, four local IP, four remote IP.
