The Concept

Great Apart. Perfect Together.

Great Apart

The X20X family features modules of two kinds: EM "controller" modules carry the CPU, Ethernet controller, memory, and other digital circuitry. RJ "jack/connector" modules feature Ethernet magnetics, an RJ45 jack, and a shielded housing that partially covers the modules.

The EM modules can be used with any standard Ethernet front-end, such as the YCL-PTC1111-01G RJ45 connector with integrated magnetics.

Depending on the model and configuration, these devices can work either as fixed-function, ready-to-run serial-to-Ethernet converters or as BASIC-programmable controllers.

Each EM module in the X20X family has several status LEDs onboard.

The RJ modules combine standard 10/100BaseT magnetics and RJ45 jack into a single module.

Unique patent-pending design minimizes their board footprint and allows you to put other components, such as the Ethernet controller, right under them -- thus saving valuable host board space.

The modules are partially encased in a lightweight, aesthetically pleasing housing. This provides necessary shielding and mechanical stability, while keeping the rear portion of the device uncovered for better air circulation.

The housing is translucent, allowing you to place status LEDs directly on the host board, so they're visible through the RJ module's front face.

Perfect Together

The EM and RJ modules can be used together as well. EM devices tuck right under the RJ modules, effectively occupying no extra space on the host board.

In this configuration, the EM module's status LEDs are positioned right behind the RJ device's translucent face, and so remain visible.
