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.
