This is an industrial grade 4G DTU which incorporates Qualcomm platform 4G communication module SIM7600E-H. It supports multi-mode multi-band, and suits multi countries or regions. After our secondary development for the module firmware, it takes only some simple configurations to achieve bidirectional data transparent transmission between RS232/RS485/TTL serial port and 4G LTE network.
