EPS GigE Contactless Connectivity SK202 pair of 60Ghz Contactless Connecivity Modules (Port A&B), Original Version Brand: EPS Size: 67.35 mm X 31.6 mm X 16.7 mm) Features 60GHz VBand transceiver with ST60A2 Gigabit Ethernet short range contactless connectivity, preferred 3cm Full duplex, horizontal transmission, Controlled Auto negotiation RJ45 MDI interface Ethernet input NOTE: SK202A and SK202B have to used in pairs (A + B) . To allow a wireless transmission, both SK202A and SK202B are needed. A pair (A+B) order is strongly recommended. Application LED panels for modular display walls Video surveillance camera and robotics Contactless Ethernet applications (The Assembly Characteristics are shown in images.) Autonegotiation The Ethernet PHY supports 1Gbps, 100Mbps and 10Mbps speeds. In order for two Ethernet modules to communicate correctly, care must be taken that the PHY on both modules negotiate the same speed. The autonegotiation is always enabled on the Realtek PHY. It takes place independently between a module and the device connected on its RJ45 port. It is the responsibility of the application to ensure the autonegotiation result is the same for both Ethernet modules. For example, if one module is connected to a 100Mbps modem, the PC connected on the other module should be configured to the autonegotiation result is also 100Mbps. Package Including ：SK202A x1, SK202B x 1 More details are available in the User Manual.
