Usage

Allows to receive and send SMS messages (2G, 3G). Provides Ethernet over LTE (4G).

VT740 allows you to receive notifications over Ethernet, SMS notifications, SNMP connection, and others.

Provides network reservation: e.g. if the LAN connection fails, the Ethernet connection is secured using 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.

Panel

"Main antenna" - Connector, used when the modem is installed inside of the appliance to connect the LTE main antenna. ( The main antenna is supplied together with the modem).
"SIM card" - SIM card slot with an injector.
"Status" - displays modem status. Blinking = working.
"Auxiliary" - Connector, used when the modem is installed inside of the appliance to connect LTE auxiliary antenna. The additional antenna helps to strengthen the signal level. ( Auxiliary LTE antenna is supplied together with the modem).

Installation

You can install the modem while the system is turned On. You may wait up to 3 minutes until the Telecom operator information is renewed.

Step 1		Unscrew the M3 screw from the LTE metal panel.
Step 2		Use the wire cutter tool to cut off the metal inserts. You can dispose of the metal inserts.
Step 3		Plug the VT740 slot modem as shown on the picture into the opening. The board should slide into the guide rails (marked as “1”) and plug into the jack (marked as “2”).
Step 4		Put the LTE metal panel back in (marked as “1”). Screw the M3 screw back in fixating the LTE metal panel (marked as “2”).
Step 5		Screw the main LTE antenna into “Main” antenna” jack. If you want to strengthen the signal, you can screw in the second auxiliary antenna into “Auxiliary” jack.
Step 6		Plug in the micro SIM card. The SIM card slot has an injector.
Step 7		You are ready to go! Turn on the system. You can install the modem while the system is turned On. You may wait up to 3 minutes until the Telecom operator information is renewed.
