This Gateway board packs all essential features in one package: secure power connector, I\/O ports, serial and IoT communications, fast and a reliable internet connection for industry applications, where long lifecycle is a must. The TRB255 can be used to integrate modern and legacy industrial equipment in one solution and with a wide range of hardware and software features such as: LTE Cat M1, NB-IoT, SMS control, Firewall, open VPN, IPSec, RMS - users can be ensured that data can be reached securely and safely. Without this backward compatibility to EGPRS (2G) networks, users can upgrade already working devices to ensure that after the 2G network is switched off, your equipment will be accessible with the support of LTE Cat M1, NB-IoT.\n\u003cbr\u003e\u003cbr\u003e\u003cp\u003e\u003ciframe allow=\"accelerometer; autoplay; encrypted-media; gyroscope; picture-in-picture\" allowfullscreen=\"\" frameborder=\"0\" height=\"315\" src=\"https:\/\/www.youtube.com\/embed\/M6I4frmAIWQ\" width=\"560\"\u003e\u003c\/iframe\u003e\u003c\/p\u003e\n\u003cdiv class=\"gowifi_pd_det_desc_features_header\"\u003eFeatures\u003c\/div\u003e\n\u003cdiv class=\"gowifi_pd_det_desc_features\"\u003e\u003cul\u003e\n\u003cli\u003eLTE Cat M1 \/ Cat NB1 \/ EGPRS Communication\u003c\/li\u003e\n\u003cli\u003eDual-SIM with auto Failover, Backup WAN and other SW features\u003c\/li\u003e\n\u003cli\u003eRS232\/RS485 serial communication interfaces\u003c\/li\u003e\n\u003cli\u003eMultiple Inputs\/Outputs for remote monitoring and control\u003c\/li\u003e\n\u003cli\u003eWide range of power supply voltages 9 - 30V\u003c\/li\u003e\n\u003cli\u003eTeltonika Remote Management System compatible\u003c\/li\u003e\n\u003c\/ul\u003e\u003c\/div\u003e\n\u003c\/div\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003cdiv style=\"margin-bottom:20px;\"\u003e\n\u003ctable class=\"gowifi_pd_tb_spec\"\u003e \u003cthead class=\"gowifi_pd_tb_spec_head\"\u003e \u003ctr class=\"gowifi_pd_tb_spec_head_row\"\u003e \u003cth class=\"gowifi_pd_tb_spec_head_th_desc\"\u003eDetails\u003c\/th\u003e \u003cth class=\"gowifi_pd_tb_spec_head_th_spec\"\u003e\u003c\/th\u003e \u003c\/tr\u003e \u003c\/thead\u003e \u003ctbody class=\"gowifi_pd_tb_spec_det\"\u003e \u003ctr class=\"gowifi_pd_tb_spec_det_row gowifi_pd_tb_spec_row_num_1\"\u003e\n\u003ctd class=\"gowifi_pd_tb_spec_det_td_desc\"\u003eProduct code\u003c\/td\u003e\n\u003ctd class=\"gowifi_pd_tb_spec_det_td_spec\"\u003eTRB255\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr class=\"gowifi_pd_tb_spec_det_row gowifi_pd_tb_spec_row_num_0\"\u003e\n\u003ctd class=\"gowifi_pd_tb_spec_det_td_desc\"\u003eMobile\u003c\/td\u003e\n\u003ctd class=\"gowifi_pd_tb_spec_det_td_spec\"\u003eLTE (Cat M1) \/ NB-IoT \/ EGPRS\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr class=\"gowifi_pd_tb_spec_det_row gowifi_pd_tb_spec_row_num_1\"\u003e\n\u003ctd class=\"gowifi_pd_tb_spec_det_td_desc\"\u003eSIM\u003c\/td\u003e\n\u003ctd class=\"gowifi_pd_tb_spec_det_td_spec\"\u003eDual SIM with auto-switch\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr class=\"gowifi_pd_tb_spec_det_row gowifi_pd_tb_spec_row_num_0\"\u003e\n\u003ctd class=\"gowifi_pd_tb_spec_det_td_desc\"\u003eSerial Communication Modes\u003c\/td\u003e\n\u003ctd class=\"gowifi_pd_tb_spec_det_td_spec\"\u003eConsole, OverIP, Modem (planned), Modbus RTU master, Modbus gateway, Modbus Slave, NTRIP client (planned)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr class=\"gowifi_pd_tb_spec_det_row gowifi_pd_tb_spec_row_num_1\"\u003e\n\u003ctd class=\"gowifi_pd_tb_spec_det_td_desc\"\u003eMonitoring and Management\u003c\/td\u003e\n\u003ctd class=\"gowifi_pd_tb_spec_det_td_spec\"\u003eWeb UI, FOTA, SSH, SMS, JSON-RPC, Modbus, RMS\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr class=\"gowifi_pd_tb_spec_det_row gowifi_pd_tb_spec_row_num_0\"\u003e\n\u003ctd class=\"gowifi_pd_tb_spec_det_td_desc\"\u003eCPU\u003c\/td\u003e\n\u003ctd class=\"gowifi_pd_tb_spec_det_td_spec\"\u003eQualcomm QCA9531, MIPS 24kc, 650 MHz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr class=\"gowifi_pd_tb_spec_det_row gowifi_pd_tb_spec_row_num_1\"\u003e\n\u003ctd class=\"gowifi_pd_tb_spec_det_td_desc\"\u003eRAM\u003c\/td\u003e\n\u003ctd class=\"gowifi_pd_tb_spec_det_td_spec\"\u003e64 MB, DDR2\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr class=\"gowifi_pd_tb_spec_det_row gowifi_pd_tb_spec_row_num_0\"\u003e\n\u003ctd class=\"gowifi_pd_tb_spec_det_td_desc\"\u003eFlash\u003c\/td\u003e\n\u003ctd class=\"gowifi_pd_tb_spec_det_td_spec\"\u003e16MB SPI Flash (4 MB available for user)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr class=\"gowifi_pd_tb_spec_det_row gowifi_pd_tb_spec_row_num_1\"\u003e\n\u003ctd class=\"gowifi_pd_tb_spec_det_td_desc\"\u003eOperating System\u003c\/td\u003e\n\u003ctd class=\"gowifi_pd_tb_spec_det_td_spec\"\u003eRutOS (OpenWrt based Linux OS, SDK package with build environment provided)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr class=\"gowifi_pd_tb_spec_det_row gowifi_pd_tb_spec_row_num_0\"\u003e\n\u003ctd class=\"gowifi_pd_tb_spec_det_td_desc\"\u003eI\/O\u003c\/td\u003e\n\u003ctd class=\"gowifi_pd_tb_spec_det_td_spec\"\u003e3 x Configurable Inputs\/Outputs.
