The RJ203 can also be used in combination with the EM203 Ethernet-to-serial module (documented in the "Serial-over-IP Solutions Manual") or EM1206 BASIC/C-programmable Ethernet module.

Connector pins of the EM203 and EM1206 are designed to mate with interface pads of the RJ203. The EM203 (EM1206) fits "under" the RJ203 and partially within the recess area provided by the RJ203. This recess area is formed by a translucent housing of the RJ203. When the EM203 (EM1206) is combined with the RJ203, the status LEDs of the EM203 (EM1206) become positioned close to the translucent front wall of the RJ203 and remain visible through the front face of the RJ203.

Detailed mechanical information can be found in the Mechanical Dimensions: RJ203+EM203 and Mechanical Dimensions: RJ230+EM1206 topic.
