Usage

Allows to receive and send The VT740 module supports receiving and sending SMS messages (via 2G , 3G). Provides Ethernet and 3G networks, as well as providing Ethernet connectivity over LTE (4G). Can be installed in . It ensures continuous communication by sending notifications over various channels like Ethernet, SMS, and SNMP. One of its critical functions is providing network redundancy; if the LAN connection fails, the module automatically switches to LTE 4G to maintain the Ethernet connection.

The VT740 can be integrated into Vutlan monitoring systems, including VT335t, VT336t, VT825t, VT855t, and VT960t monitoring systems. Power cycling is . Additionally, it features an embedded power cycling function, allowing remote rebooting of connected devices.

This module is ideal for network backup and ensuring communication reliability in mission-critical environments.

Info
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.

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	Image RemovedImage Added	Unscrew the M3 screw from the LTE metal panel.
Step 2	Image RemovedImage Added	Use the wire cutter tool to cut off the metal inserts. You can dispose of the metal inserts.
Step 3	Image RemovedImage Added	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	Image RemovedImage Added	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	Image RemovedImage Added	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	Image RemovedImage Added	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.
