The generated hexadecimal or binary code determines the direction of output in terms of data flow. These mechanisms often have only two modes of operation such as normally open NO and normally close NC.
In the normally open NO mode, the DIP function enables the connection between the input and output terminals of an electromechanical assembly.
On the other hand, in the normally closed NC mode, the DIP function disables the connection, which terminates the flow of signals. Different pole and throw configurations are available in slider or rocker DIP interfaces, listed as follows. This offers two poles and a single throw. This means the operator can choose the flow of data from input. The operator can decide from where the input is to be taken and sent to the output. Any of these DIP interfaces can be implemented on the gigabit media converters.
Let us discuss the significance of DIP switches on media converters. The DIP function on media converters helps enhance the performance of unmanaged media converters. However, the DIP function on media converters has to be operated manually. The DIP function on unmanaged gigabit media converters is of significance because it allows a few functions of managed switches in unmanaged switches.
These enabled features include auto-negotiation, cross-over, duplex mode transmission, etc. The performance monitoring is enhanced by using the DIP function on the media converter as an integration of DIP offers warnings on potential errors in the link.
This is achieved during the mode selection process. Fault identification, fault propagation, loopback mode, etc can be achieved by using DIP functions. The flow of data can be manually controlled in order to reduce link failure. The usual functions performed by the DIP switches on the unmanaged media converters are listed below. LFC series are newest series of media converters. Used with their compatible LFC-CH12 fiber optic chassis they can be aggregated up to 12 units in a 19" wide and only 1RU of height space only.
This is the highest density attainable for unmanaged fiber media converters. The LFCSS fiber to fiber media converter has utmost flexibility for fiber change by using two SFP slots that can be populated with any rate and type of optics.

In the Store and Forward mode, the entire frame will be stored in the memory for inspection on its destination address, source address, and the CRC.
If no errors are present, the frame is forwarded to the appropriate port. This process ensures that the destination network is not affected by corrupted or truncated frames, but may cause latency. In Modified Cut Through mode, the frame will be forwarded as soon as the destination address is identified. This mode allows lower latency and saves buffer space. However, the drawback is that network performance may be impacted by forwarding corrupted or truncated frames which cannot be detected by reading only the destination address.
These bad frames can create broadcast storms wherein several devices on the network respond to the corrupted frames simultaneously. An unmanaged media converter can run in this mode by the DIP switch on it.
Media converters from different vendors may have different DIP switch settings. Some use one key to control a function, and some use two or more. The following table is extracted from the user manul of a media converter.
