Description

The Sync2IP or sync to IP Converter is an interface conversion product that transports serial communications over an Ethernet LAN. It converts a full duplex synchronous or asynchronous serial data stream to a UDP/IP packet stream. The serial stream consists of transmit and receive data with selected control signals. Serial Data rates of 1200 bps to 64 Kbps for simultaneous two-port operation, and up to 128 Kbps for single-port operation are available to the user. The Sync2IP is a cost effective HDLC to IP Converter.

Two or more Sync2IP units are required to transparently connect serial devices over the LAN. Data conversion is independent of the serial port protocol.

In the synchronous mode the Sync2IP sends and receives the data bit-for-bit at the synchronous port operating clock rate. Therefore, the interconnected Sync ports must operate at the same nominal clock rate. Guaranteed delivery of Sync data requires error recovery in the customers equipment.

In the asynchronous mode the data is sent on byte boundaries, and when Async flow-control is honored the interconnected Async ports may operate at different speeds. The Async byte format supported is 8 data bits, 1 stop bit, and no parity. Therefore the Async byte frame is 10 bits in length. In Async mode there is guaranteed delivery. Packets will be retransmitted for up to 15 seconds, after which time the session will be reset.

The Sync2IP is configured via the HTML Browser interface or front panel LCD display and input buttons. The Sync2IP system firmware upgrades are accomplished via the 10/100 LAN port.

Any combination of DCE and DTE devices may be supported over the peer-to-peer connection between one Sync2IP and the other. However, in Sync mode the Sync2IP does not support a connection of two DCE customer devices.

In the DCE-DCE configuration RTS/CTS flow control is passed through the LAN and exposed as DCD at the peer Sync2IP unit.

In the DCE-DTE configuration RTS, CTS, DCD, DSR, and DTR are passed through the LAN and presented (in time-sequence with the data) as the same (unprocessed) signals to the device connected to the peer Sync2IP.

In the DTE-DTE configuration DCD control is passed through the LAN and exposed as RTS at the peer Sync2IP unit. (Async only)

Xon/Xoff flow control is not processed by either Sync2IP peer. Xon/Xoff are considered data by the Sync2IP and left to the connected user devices to contend with.

The Sync2IP is housed in a sturdy 1U high chassis and has a 90-240VAC power supply or optional -36 to -72VDC power supply. Additionally, an optional 2-up 1U high chassis contains two Sync2IP printed circuit cards for high density applications. The Sync2IP has a 3-year warranty and a 24 hour turnaround on warranty repairs.
