USR-LTE-7S4 4G Module is used to transmit data between serial port and network server by Operator network. It is configured by AT Command and work in dual transparent transmission mode. USR-LTE-7S4 is of small size, which is widely used in LTE, WCDMA and TD-SCDMA network.And USR-LTE-7S4 is compatible with 2G module 7S2/7S3, user can replace 7S3 easily. We add Watch dog function in firmware to ensure the stability if work for a long time.
Support TDD-LTE, FDD-LTE, WCDMA, TD-SCDMA, GSM/GPRS/EDGE network Based on embedded Linux system, has high stability Support RNDIS remote network driver interface, USB connection Support 4 sockets, support TCP and UDP Each connection supports 4KB data cache, can choose data cache to avoid data loss in abnormal connection Support sending identity header and heartbeat packet Support remote configuration via SMS Work modes: network transmission mode and HTTPD mode Support basic instruction set Support socket distribution protocol, can send data to different Sockets FTP else upgrade protocol, apply to remotely update device FTP itself upgrade protocol, make firmware the latest version Support sending Chinese/English SMS via simple instructions Support class RFC2217,can modify module serial parameter via network dynamically Pins compatible with pins of USR-GPRS232-7S2/7S3, user can replace 7S2 and 7S3 with USR-LTE-7S4
