Usage
Allows to receive and send SMS messages (2G, 3G). Provides Ethernet over LTE (4G). Can be installed in VT335t, VT336t, VT825t, VT855t, and VT960t monitoring systems. Power cycling is an embedded function.
The same PCB of VT740 is used for i
and t
series (e.g. VT335i and VT335t). But The metal enclosures use a different metal panel for holding the modem. t
series have an additional screw to hold the panel. Thus the installation is slightly different. But in all other regards, it is the same.
