IP Tube RS232 SER - Engage Communication

Flexible Serial Data Extensions over IP Packet or MPLS Networks
The IP•Tube SER RS232 converts RS232 serial data connections into IP packets, extending the serial data over very cost
effective Ethernet or MPLS based LAN/WAN/MAN wired and wireless networks. Synchronous, Asynchronous, Isochronous or
HDLC serial data is encapsulated into IP packets. This facilitates the interconnection of Serial Data over IP between Serial Bulk
Encryptors (KIV7/OMNI), Data Terminals, Data Acquisition Systems, WAN Routers and Bridges, SCADA RTUs....
Layer 1 with Isochronous Support
In Layer 1 operating mode every bit is encapsulated into an IP packet. The size and frequency of the IP packets can be set
with data bit rates from 75 bits to 256 kilobits per second. Isochronous serial protocols, such as Conitel, are transported
synchronously to maintain message alignment. A configured number of incoming packets are buffered in order to
compensate for the packet delivery jitter introduced by the network. The size of the Tube bit buffer is configurable to
accommodate the peak amount of jitter.
Asynchronous Over IP
Asynchronous characters from the RS232 interface with 5 to 8 data bits, baud rates from 1.2 to 38.4 kilobits, 1 or 2 stop bits
that are with or without parity are efficiently encapsulated into IP packets. The encapsulation supports block mode transfers
to minimize the bandwidth required. Additionally the latency is controlled by setting the Tube Bytes per packet.
In Layer 2 operating mode HDLC Data frames, such as those used by Wide Area Networking protocols PPP and Frame Relay
or proprietary Data Links, are transported within IP packets as HDLC over IP. The Serial to Packet conversion only occurs when
HDLC frames are active.
IP•Tube SER RS232 Standard Features
Dual LAN Interfaces
All IP•Tube SER RS232 models ship with dual 10/100BaseT
Ethernet LAN ports. The dual Ethernet interfaces provide for:
• Management interface on LAN port 2 when LAN port 1
is connected to a VPN tunnel
• Protector Option for Redundant Packet Path connections
with Constant or Switch Over Criteria
Assured Delivery Protocol
In order to assure high quality communications over links
with intermittent or noisy performance, such as Wireless,
the IP•Tube SER RS232 employs Engage’s robust Assured
Delivery Protocol with the following benefits:
• Packet out of sequence detection and re-sequencing
• Duplicate skipping
• Lost packet retransmissions with configured delay

IP•Tube SER RS232 Optional Features
Protector OPTION -PRO
The protector option utilizes the second LAN interface
as a redundant path for the interconnection of the IP
encapsulated SER RS232 data. The extension of the SER
RS232 has a fault tolerant link that is configured to always
on, or with switch over criteria.
Serial Redundancy OPTION -Y
The Serial Redundancy option is used to switch the RS232
connection to a secondary IPTube in the case of a network
or equipment failure maximizing network availability by
providing complete hardware redundancy for mission critical
