Wireless modem for telemetry and SCADA systems, / radiomodem / radio modem/ VHF, UHF

T-MOD C48 Series wireless modem provides a data radio chanel, transparent to the protocol (¡.e. accepts al1 half-duplex protocols), with 4800 bps throughput through a RS-232 interface.

It provides outstanding long-range point-to-multipoint radio communication for SCADA systems (PLC, RTU and apllication specific devices). A single T-MOD C48 Series unit may act as terminal, base station or repeater. Thus, dramatically reducing maintenance and operation costs.


  • 4800 bps @ 12,5 KHz
  • Transparent to protocol
  • Modbus RTU Store & Forward repeater
  • Point-to-rnultipoint or peer-to-peer network
  • RSSI rneasure in dBrn (digital or voltrneter)
  • Long range links in UHF and VHF
  • Frequencies with or without license

Licensed or license-free frequencies. Long range.


TMOD C48 is available in UHF and VHF bands, with or without license (433 MHz). Its output power is configurable between 0.1 W and 5.0 w. the receiver provides excellent sensibility allowing for links up to a range of 50 Km (depending on propagation conditions).


First character store & forward repeater


The Store & forward function (stores and forwards each protocol frame) allows to set up a repeater by means of a single unit and a single frequency (no frecuency change). That function is available for al1 protocols with the network address in the first character (as, for instance, Modbus RTU)


Tough and easy-to-install units


Configuration by using the intuitive TMOD Suite software. Simple set up requiring only basic software. Simple set up requiring only basic parameterization (freuency, power, adress). No auxiliary radiofrequency tools required. The unit allows to easily test the radio link quality (emitted power, received power and frame error rate).


TMOD C-48 is manufactured under ISO 9001.
