JetCon 1301-48V Replacement Note
JetCon 1301 is a compact 1-port Fast Ethernet media converter designed as small as a cigarette box, making it an ideal model that would physically fit into a chassis with limited space, such as machinery control box and duct assembly room. It also supports switch forwarding mode with abnormal packet filtering and pure converter mode for extreme low latency requirement – fieldbus and EtherCAT, which needs invariant forwarding latency in 64~1522 bytes packet length. For easy maintenance and time-saving, JetCon 1301 features remote Link Loss Forwarding technology which provides remote link down signal forwarding, acknowledging link events occurred on each end of JetCon 1301. To activate forwarding mode and LLF functions, simply adjust DIP switch and reset the converter and the reconfiguration will be applied.
For the field site harsh environmental installations such as vibrating machinery or duct assembly room applications, JetCon 1301 can be easily mounted directly onto DIN rail and powered with DC 18~32V or AC 12~27V for applications, where DC input is not available.
Besides, for particular 48V DC industrial environments, JetCon 1301-48V model is available to be powered with DC 36~60V input. With the Ingress Protection grade 31 and rigid aluminum case, JetCon 1301 can survive and have excellent performance under -10~70°C temperature range, severe electromagnetic interference and outcoming vibration.
The high MTBF value of over 500,000 hours, 5-year global warranty and endurable performance of JetCon 1301 series give you the reliable choices for hazardous applications.

Switching Converter Mode and Pure Converter Mode
The JetCon 1301 can be used in two different modes, switching converter mode and pure converter mode. The store-and-forward technology is implemented in switching converter mode. It will filter out abnormal packets to maintain network efficiency, and support the data forwarding rate up to 148810 pps in full wi re speed wi th packet length f rom 64 to 1522 bytes. In the pure conver ter mode, the JetCon 1301 only conver ts signal between copper and fiber port without any packet check, and operates
in the speed of minimum data forwarding latency.
Traditionally, media converter is used for the signal conversion between electronic and optical. Most of media converters are not capable of handling all kinds of packet sizes. A major drawback is that they cannot support 10/100Mbps auto negotiation and auto detection function for the cross-over or straight cable. The pure converter mode has the advantage of suppor t ing ext reme low t ransfer latency, even when the packet is with a CRC error, and when the packet length is below 64 bytes. Some of special devices need pure converter and they need it to operate simply without any features.
JetCon 1301 can be configured as Switching converter or Pure Converter mode by a DIP Switch. For CSMA/CD compliance, the UTP port supports 100Mbps Full Duplex when setting JetCon 1301 as pure converter. If setting as 100Mbps half duplex mode, the available link distance will be 60 meters only. In the switch mode, it will not have this limitation - the link distance can be reached up
to 100 meters.
In pure converter mode, the JetCon 1301 will operate with the minimum latency, 1.6 micro second. The 2 ports of JetCon 1301 series are inter-connected via MII signals, therefore the internal switch MAC and packet buffer are not used. Besides, the packet length will not be limited and will reach up to 1600bytes. The updated configuration will be available after resetting power.
Auto Fault Detection through Link Loss Forwarding
When using traditional fiber converters, users often encounter the following problem: a fiber converter acting like an ordinary unmanaged 2-port switch. When one of the fiber converter's ports fails (e.g. the TX port), the other one (e.g. FX port) continues to receive data via the media (e.g. fiber), confusing the device on the other end of the media by indicating that the connection is still intact. But, by the time the disconnection is found, this error causes a great amount of loss.
If a port loses the connection for any reason, it will activate Link Loss Forwarding to shut down the other port, as a result, allowing the device on the other end of the media to detect the disconnection. The administrator over the network can be informed of the disconnection immediately, and can react promptly to the situation, greatly reducing loss caused by any link failure.
The Real Time Ethernet Solution- EtherCAT Test
JetCon 1301, an Industrial 10/100Base-TX to 100Base-FX Multi-Mode (JetCon1301-m) / Single- Mode (JetCon1301-s) fiber converter, has passed the system test of an open Real-Time Ethernet solution, EtherCAT. Cooperating with the testing laboratory of Backhoff, Korenix sets a successful milestone to enable Real Time Ethernet-EtherCAT, the fastest "industrial Ethernet
control in the world", over fiber optics. For communication tasks, not only the defined latency (cycle time) is important, but the jitter also has to be limited. During the system test, there is no noticeable Jitter between two JetCon 1301 converters connected via fiber end, whereas EtherCAT devices attached to the other Ethernet end. The system has been setup and tested to
meet all criterions of EtherCAT protocol. For standard Ethernet jitter, specifications of only 100 μs to 3 ms are possible.
Reliable Mechanical Design
Industrial conver ters are of ten placed in harsh environments and are required to run non-stop. The quality of industrial converter is constantly being tested by rugged conditions, such as high or low temperature conditions, impact, vibration, or corrosion. To cope with demanding industrial environments, the aluminum alloy case of JetCon Industrial Converter is rigid, shock-proof, and conforms to IP31 housing design. In order to prevent power lines from damage caused by falling dust particles and water drops in an industrial environment, Korenix's engineers specially designed the terminal block for power and relay at the bottom of the unit, greatly reducing failures caused by this environment.
