IPR400 S2

A 2-in-1 Interoperability Gateway and RoIP Gateway

A 2-in-1 analog Interoperability Gateway and RoIP Gateway

A 2-in-1 analog Interoperability Gateway and RoIP Gateway that makes it super easy to interconnect different radios reliably and fast.



Why Choose the IPR400 S2 with RoIP Gateway Software?

The IPR400 S2 is a full featured, fast and flexible multi-channel VoIP radio interface with RoIP gateway software. It combines Voice over IP extensions for analog radio equipment and interoperability between disparate radio systems all in one.

The 4 ports of the IPR400 S2 can be linked together internally to the IPR400 S2 or with VoIP in a myriad of combinations, making the device ideal for connecting repeater sites. The gateway also features SIP connectivity for use with dispatch consoles such as RediTALK-Flex, altusomni or omnicore.

When the IPR100 is not enough, the IPR400 S2 offers isolated 4-wire E&M interfaces, multi-casting, voice activity detection, voice compression, SELCALL & DTMF signalling, encryption and RS-232 data tunnelling.

To make configuration a breeze, the IPR400 S2 now incorporates software configurable E&M signals. Using a web browser, you can configure contact, voltage or switched (power or ground) operation for both the M (PTT) outputs and the E (Busy) inputs.

PTT over Cellular (PTToC) is supported as is Remote Control over IP.

Connect Smart Phones and Radios

Push To Talk over Cellular | PTToC | PoC

A remote communications app connects you with all devices in the field, allowing you to stay connected anytime and anywhere. This cloud-based service is integrated with Omnitronics IPR110+ and IPR400 S2 Gateways as standard, and also integrates into Omnitronics Radio Dispatch Systems. Keeping communication lines open, even when you are without your radio.

IPR400 S2 Use Case

High Path Loss Environments

Connect two-way radio communications in areas where signals normally cannot pass through walls or obstacles, i.e. from the surface to underground mine levels, through tunnels, across large buildings.

IPR400 S2 Use Case

Remote Controlled Linking

Dynamically changing link groups in real-time via omnilink Windows application, even when out in the field.

IPR400 S2 Use Case

Connecting Remote Radio Repeater Sites Using IP

When faced with multiple sites using analog two-way radio that are far apart, connecting repeater sites using IP is an easy way to join communications between them.

IPR400 S2 Use Case

Integrating Voice LMR with PTToC

Integrating mobile phones into a two-way radio network has never been easier when interconnecting or bridging multiple LMR channels at a repeater site.

Mission-Critical Radio Gateway

7+ Years of Up Time and Counting

The Omnitronics IPR400 Radio Gateway has got what it takes to be mission-critical!

Installed on a remote oil platform, this IPR has been continuously running for 2593 days, that’s 7+ Years without a fault, reset, power outage or upgrade.

When the organisation’s dispatch system was upgraded from a DX-64 to RediTALK-Flex, all the IPR400 needed was a firmware upgrade to suit the new requirements and it was straight back in service.  Counting up again from 0 until we see it again in 7+ years…

We'll find the perfect system for your individual needs.
