Piciorgros TMO-100v3 telemetry modem

The TMO-100 telemetry modem enables data to be transferred to one or more positions anywhere within a TETRA network. The all-in-one solution includes a controller, router, modem and mobile radio, making it suitable as a turnkey solution.

The product is equipped with two serial interfaces (optional RS-232 or RS-422/285) and one ethernet port (10/100 Mbps). Serial protocols include Modbus-RTU, IEC60870-5-101, DNP3, ROC, BSAP, PakBus and Siemens SINAUT. For the Modbus RTU protocol, the TMO-100 makes it possible to send out event-driven alarms.

The unit can be equipped with an I/O board, the inputs of which send status alarm messages to the master radio station. The master radio station stores the alarms in Modbus registers, where they can be easily polled from the master PLC.

The product can also process UDP and TCP protocols. After the device is turned on, a PPP-connection is automatically established to the TETRA network, whereupon the TMO-100 receives an IP network address and can immediately send IP data from the local ethernet interface to the TETRA-IP-world and vice versa. The modem utilises NAT, port forwarding and port translation, which turns the device into a fully featured TETRA router.
