IP•Express RS232 is a Wide Area Network solution that bridges Ethernet Packets or routes the Internet Protocol through a High Speed RS232 WAN interface. The RS232 WAN port supports Point to Point and Frame Relay Wide Area Networking Protocols with 24/7 proven interoperability.

IP•Express RS232 are used extensively with Wide Area Networks for high performance branch office connectivity and Internet access. Internet Service Providers deploy the IP•Express RS232 as a customer premise solution. Corporations and Government agencies select the IP•Express RS232 for its ease of installation and reliability.

The IP•Express RS232 is a very reliable, high performance and cost effective IP WAN Router and Ethernet Bridge for interconnecting remote LANs and for shared high performance Internet Access. 

IP•Express RS232 is great for:

  • Branch Office Connections
  • Education District Networking
  • Ethernet to RS232 Conversion
  • Shared Internet Access
  • Multi Megabyte File Transfers

Network Security is provided with Full On Source, Destination Address; Port and Flag IP Packet filtering. Interconnectivity is able to be selectively controlled at the network, device and application layers.

Management of the IP•Express RS232 is accomplished with a Command Line Interface that is accessed through a Console or Telnet connection. Templates of the most common configuration provide for an Edit and Paste configuration. SNMP MIB I and II support is a standard feature.

Rack Mount Kit

The IP•Express products are easily installed in 19" and 23" racks with the Rack Mount Kit. Easy access to both front and rear sides facilitates technician maintenance procedures.


Two T1 Inverse Packet Multiplexer

IP•Express RS232 is a high performance, bandwidth scalable, IP WAN router. The RS232 port is able to interconnect to remote locations at 2 Mbps. Standards based WAN protocols, PPP, Multilink PPP, and Frame Relay, ensure interoperability.

MPEG IP Video Redundancy Switch

REDundant IP Video configuration automatically switches from the Primary to a Secondary Encoder's IP Video Stream for mission critical broadcasts and is available with the IP•Express RS232-IPM-RED. A one second absence of IP packets from the Primary Encoder results in the switch to the Secondary Encoder. The WAN bandwidth is reserved for a single feed.

MPEG IP Multicast Streaming Video

IP•Express RS232-IPM models deliver MPEG IP Streaming Video over Inverse Packet Multiplexed RS232s. The Inverse Packet Multiplexer provides the bandwidth necessary for the delivery of broadcast quality video feeds for a single MPEG Video. IP Multicast is a standard feature of the IP•Express RS232 and is utilized to distribute MPEG video simultaneously to multiple decoders.
