IPTBridge ZFA over IP

Brief Description

The world-wide radio networks provide besides digital voice communication the possibility to transmit data. Data SIM-Cards for M2M applications (machine-to-machine) are optimally designed for professional data use. The universal radio modem UniMod LTE is supposed for remote inquiry of measurement data of any kind, especially however for telecounting applications. Optionally, a fault or status message can be queried or a switching command can be sent. The UniMod LTE supports the following modes:

  • Client mode for meter data communication according to DIN 43863-4 (IP-Telemetry), optionally with encryption (TLS version 1.2)
  • Server mode with static IP address and VPN access

The UniMod LTE can be used in LTE (Long Term Evolution / 4G: fourth generation) network with an arbitrary number of providers. It requires however the infrastructure for operating mobile. An existing LTE infrastructure with corresponding frequency ranges is one of the basic requirements. If LTE coverage is missing, the radio modem automatically switches to UMTS (3G) or GPRS (2G) (fallback technology). The modem supports an interface for Micro-SIM-Cards. For communication is the provision of a SIM-Card with data tariff needed.


The UniMod LTE is equipped with a built-in RS485 2-wire interface. Other interface standards can be realized by plugging the appropriate interface module. Currently the following modules are available:

  • CS (20 mA current loop) interface module, active (supplies current) or passive
  • RS232 interface module (uses signals RxD, TxD, CTS, RTS, GND)
  • RS485 2-wire module
  • RS485 4-wire module
  • M-Bus active module (can supply up to 20 devices)
  • M-Bus passive module

Communication is possible with many standard protocols, like DLMS, IEC1107, VDEW2+, Modbus, M-Bus, IEC60870, SCTM, LSV1 etc. (transparent reading)
