LRM Radio Module with Integral Modem Launched
A new PCB mountable module incorporating both an easy to use radio section and an internal modem capable of data rates up to 9600bps has been introduced by RF DataTech. The LRM module is a complete high performance radio modem built into a small screened can designed to mount directly onto a PCB for OEM applications.

IEC 60870-5 Store & Forward Support Added to Modem Range
Repeater support for IEC 60870-5 (IEC 870-5) protocol has been added to the RF DataTech radio modems. This behaves in a very similar way to the existing support for repeating of MODBUS messages and is based of storage and subsequent re-transmission of messages for protocol addresses specified in a routing table.

PRX Paging Receiver Introduced
RF DataTech are pleased to announce the introduction of a new high specification paging receiver meeting the ETSI EN300 224 requirements for base-station receiver use. The PRX range has an RS232 output and 4 switched digital outputs. The RS232 port allows ASCII message content to be passed serially to an external device, while the 4 programmable digital outputs allow remote switch operation under the control of a paging system. The switched outputs can be operated in an On/Off, Momentary or Timed mode making them ideal for sign control or remote switch operation. They can also be configured to pulse on for a configurable time every time a message is received on one of the addresses which pass data to the serial port. This allows the outputs to be used to alert an operator to the receipt of an incoming message.

ZRT470 is FCC and Industry Canada Certified
The UHF version of our popular ZRT radiomodem has now been certified by the FCC and Industry Canada (IC) to allow it's use throughout the USA and Canada. Although the ZRT range has been available with full European approvals and certification for some time now, recent increased demand from America for low-cost, high-performance data radios made this a good time to carry out the additional external testing and approval necessary for these territiories. The ZRT470 joins our top-of-the-range ART modems which were already FCC and IC certified.

New RS232/RS485/RS422 & 5V TTL Interfaces for ZRT
RS232/RS422/RS485 and 5V TTL interface options have been added to the ZRT Series low cost radio modems. Support for MODBUS and Store & Forward repeater operation has also been added. These new versions complement the original RS232-only versions and offer even greater flexibility to the designers of industrial telemetry systems. Many of todays industrial telemetry and process control products use RS485 or RS422 serial interfaces to allow multi-drop configurations and the introduction of the new versions of the ZRT allows these units to be easily connected by radio without the need for external data conversion products. The new 5V TTL version is particularly suitable for direct integration into OEM products which already use these logic levels on the main board. All the versions of the ZRT are fully compatible with each other and it is possible to mix and match the different interfaces within a single system.

RS232 and RS485 Bluetooth Modems
Two new Bluetooth to Serial Data converters have been added to our product range. RS232 and RS485 versions are available. They can be used in pairs to replace a serial cable or can be used in conjunction with a Bluetooth enabled PC to give the PC licence-exempt wireless access to an RS232, RS422 or RS485 serial port on a remote device.

New ZRT Radio Modem
RF DataTech are pleased to announce the launch of the new low cost ZRT series of radio modems. The new ZRT replaces our popular QRT range and adds a number of new and improved features taken from our higher specification ART and SRT ranges. The ZRT Series has been designed as a flexible range of high specification, low cost radio modems for stand alone applications or for integration into OEM products. The design has been optimised for reliability and low current consumption, making the ZRT suitable for operation on remote sites without mains power. Applications include security, command & control, data logging, SCADA, telemetry, remote switching or any similar applications where serial data needs to be transmitted and a cable is not the most practical solution. Compared with the older QRT, the ZRT has an improved and updated internal modem capable of operation up to 9600bps, 80 user programmable channels where the QRT only had 9, more LED status indications and the addition of a packetisation mode for improved immunity to squelch tail effects.
