With an increasing demand for cold-chain supply chains, Teltonika is offering the ability to monitor real-time information from freezer trailer thermographs. Each thermograph has an RS232 communication line where FMM640 devices can connect via COM1/COM2 port of the device. The solution is easy to install and configure. This allows you to monitor the main information of the freezer trailer such as Temperature, Fridge door status, Alarms, etc., and generate events according to your needs. For more information please refer to the installation manual below.
NOTE: this feature is available from FW ver. 01.02.02.Rev.00
Supported Thermographs[edit source]
FMM640 can be connected to DataCold600, Transcan2, TouchPrint thermographs.
Refer to the table bellow to see which freezers use which thermograph:
RS-232 Interface[edit source]
RS-232 supports full-duplex communication which means the data can be both sent and received at the same time as they use separate transmission lines. Most of the modes are the same as for FMM640. When entering Sleep or Deep sleep RS-232 will be powered off. FMM640 RS-232 connection diagram is shown in the figure below:
