Lantronix M114B00FS — ROW LTE Cat 1 bis IoT Serial Modem, RS-232 & USB

The Lantronix M114B00FS is a small, low-power cellular modem for retrofitting serial equipment with an IP connection. Typical examples include electricity meters, PLCs, lifts, vending machines and POS kiosks. It is the ROW (rest of world) M114B, built for EMEA, LATAM and India on LTE Cat 1 bis bands B1, B2, B3, B4, B5, B7, B8, B20, B28, B66, B38, B40 and B41 with 2G fallback. The antenna attaches through a single SMA connector. Certifications for the M114 bis are CE, UKCA, UL/CB and RCM, and Lantronix also publishes KC and NCC certificates for this SKU. The housing is brushed aluminum and measures 60 x 66 x 21.7 mm without connectors, at about 95 g. Serial devices connect through full RS-232 on a 9-pin sub-D, and a host can use USB 2.0 over Type-C. The optional SnapCap accessory converts the RS-232 port to isolated RS-485 with half- or full-duplex operation and cable runs of up to 1.5 km. Two I/Os can each be set as a 0-48 V DC analogue input with 12-bit resolution or as an open-collector digital output rated at 200 mA and 50 V DC. The modem runs from 8-32 V DC with slow start. Worst-case figures for the M114B are 0.15 W idle, 0.36 W standby and 0.65 W at maximum transmit, which suits battery and solar installs. The mPack software suite handles PPP dial-up, generic AT commands and mPack commands over RS-232 or USB. It also offers permanent TCP/UDP client or server modes and an on-demand client, with two sockets for failover and a network connectivity watchdog. Firmware updates run over the air from your own HTTP server. The M114B also integrates with Lantronix Percepxion for remote configuration, console access, telemetry and tunneling. Lantronix publishes a product brief, user guide, quick start guide and command references for the M110 Series, and the modem carries a two-year limited warranty.
