Connecting to an MC-i3 and MC-i4 with TRU

There are two ways to connect TRU to an MC-i3 or MC-i4:

  • Connected to a control box (e.g. GX-55).
  • Connect to a PC via programming cable (PN 1001269-01).

The connection parameters vary depending on which method is used.

The MC-i4 modem cannot be connected to with TRU. You must use the web interface or MCXConfig.
