DIP Setting of SP373 Series
Port settings are made very simple by means of a DIP (Dual Inline Package) switch at the rear panel
of the module. The default setting is auto negotiation and LFPT (Link-Fault-Pass-Through) enable as
shown below. A connected network device might fail to respond to the auto negotiation mechanism
due to various reasons, and therefore, this DIP switch allows user to manually adjust the TX/RX
speed and duplex modes.
There are six pins on the DIP switch for port settings. Refer to the table below for more details.
